Automating Security Protocol Analysis
When Roger Needham and Michael Schroeder first introduced a seemingly secure protocol [24], it took over 18 years to discover that even with the most secure encryption, the conversations using this protocol were still subject to penetration. To date, there is still no one protocol that is accepted for universal use. Because of this, analysis of the protocol outside the encryption is becoming more important. Recent work by Joshua Guttman and others [9] have identified several properties that good protocols often exhibit. Termed "Authentication Tests", these properties have been very useful in examining protocols. The purpose of this research is to automate these tests and thus help expedite the analysis of both existing and future protocols. The success of this research is shown through rapid analysis of numerous protocols for the existence of authentication tests. The result of this is that an analyst is now able to ascertain in near real-time whether or not a proposed protocol is of a sound design or whether an existing protocol may contain previously unknown weaknesses. The other achievement of this research is the generality of the input process involved. Although there exist other protocol analyzers, their use is limited primarily due to their complexity of use. With the tool generated here, an analyst needs only to enter their protocol into a standard text file; and almost immediately, the analyzer determines the existence of the authentication tests.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

U.S. Policy Recommendation for Responding to Cyber Attacks Against the United States
U.S. Response Strategy for Cyber Attacks The United States has traditionally looked to its military to defend against all foreign enemies. International telecommunications and computer networks and globalization have now overcome the military's absolute ability to provide for that common defense. More than capable to respond to attacks in traditional war fighting domains of land, sea, air, and even space, the military will not be able to prevent all cyber attacks against U.S. interests. As a result, the U.S. should establish and announce the nature of its strategic responses to cyber attacks - including legal prosecution, diplomacy, or military action. Such a policy pronunciation will serve both as a deterrent to potential attackers and likely be established as a normative international standard. The outline for a response policy begins by addressing attacks based upon the prevailing security environment - peacetime or conflict. The U.S. should respond to peacetime attacks based on the target, reasonably expected damage, attack type, and source. Attacks likely to cause significant injuries and damage warrant a full spectrum of response options, while state-sponsored attacks would justify a forcible response when their type and target indicate destructive effects including widespread injury and damage.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Interagency Organization for Cyberwar
Many people take for granted things they cannot see, smell, or touch. For most people, security in cyberspace is one of these things. Aside from the securing their home personal computer with the latest anti-virus, the majority of Americans take government and corporate cyber security for granted assuming the professionals have security of the nation's military networks, sensitive government data, and consumers' personal data and financial information under control. Outside of an occasional news story about a denial of service internet attack or an "I Love You" virus, what goes on behind the closed compact disc drive doors does not concern most of the nation. The chilling fact is the nation should be concerned about what is going on in cyberspace. Since the terrorist attacks on 9/11, the nation has taken a renewed interest in securing the homeland, to include efforts to protect the countries critical infrastructure such as electrical plants, dams, and water supplies. It is no secret that terrorists are interested in striking these targets with the intent of inflicting catastrophic physical and economic damage to western civilization. What many people do not realize is, the computer network systems which monitor and manage these systems, and many others, are also under attack by what some are calling cyber terrorists. Although the government and industry has undertaken a significant amount of effort to protect the nation's military, non-military government, financial, and industrial networks, more work is necessary.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

A Study of Quality of Service Communication for High-Speed Packet-Switching Computer Sub-Networks
In this thesis, we analyze various factors that affect quality of service (QoS) communication in high-speed, packet-switching sub-networks. We hypothesize that sub-network-wide bandwidth reservation and guaranteed CPU processing power at endpoint systems for handling data traffic are indispensable to achieving hard end-to-end quality of service. Different bandwidth reservation strategies, traffic characterization schemes, and scheduling algorithms affect the network resources and CPU usage as well as the extent that QoS can be achieved. In order to analyze those factors, we design and implement a communication layer. Our experimental analysis supports our research hypothesis. The Resource ReSerVation Protocol (RSVP) is designed to realize resource reservation. Our analysis of RSVP shows that using RSVP solely is insufficient to provide hard end-to-end quality of service in a high-speed sub-network. Analysis of the IEEE 802.lp protocol also supports the research hypothesis.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Cyberspace
In the last century, the United States was protected from a direct physical attack by its adversaries due to its geographic isolation. However, today any adversary with sufficient capability can exploit vulnerabilities in the United States' critical network infrastructures using cyber warfare and leverage physical attacks to significantly impact the lives of its citizens and erode their confidence in its ability to protect their way of life. This AY-10 student research paper provides information to assist senior leaders working to prevent or to minimize the effects of future cyber attacks by a nation state or non-state actor against the United States' critical network infrastructures.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Secureqemu
This research presents an original emulation-based software protection scheme providing protection from reverse code engineering (RCE) and software exploitation using encrypted code execution and page-granularity code signing, respectively. Protection mechanisms execute in trusted emulators while remaining out-of-band of untrusted systems being emulated. This protection scheme is called SecureQEMU and is based on a modi ed version of Quick Emulator (QEMU). RCE is a process that uncovers the internal workings of a program. It is used during vulnerability and intellectual property (IP) discovery. To protect from RCE program code may have anti-disassembly, anti-debugging, and obfuscation techniques incorporated. These techniques slow the process of RCE, however, once defeated protected code is still comprehensible.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Supplementing an Ad Hoc Wireless Network Routing Protocol With Radio Frequency Identification Tags
Wireless sensor networks (WSNs) have a broad and varied range of applications, yet all of these are limited by the resources available to the sensor nodes that make up the WSN. The most significant resource is energy; a WSN may be deployed to an inhospitable or unreachable area leaving it with a non-replenishable power source. This research examines a technique of reducing energy consumption by augmenting the nodes with radio frequency identification (RFID) tags that contain routing information. It was expected that RFID tags would reduce the network throughput, AODV routing traffic sent, and the amount of energy consumed. However, RFID tags have little effect on the network throughput or the AODV routing traffic sent. They also increase ETE delays in sparse networks as well as the amount of energy consumed in both sparse and dense networks. Furthermore, there was no statistical difference in the amount of user data throughput received. The density of the network is shown to have an effect on the variation of the data but the trends are the same for both sparse and dense networks. This counter-intuitive result is explained and conditions for such a scheme to be effective are discussed.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Cyberspace and the New Age of Influence
The importance of cyberspace and the utility of networked computer systems have grown exponentially over the past 20 years. For this reason, this study advances a theory for operations in cyberspace that uses the cyber domain to strategically influence an adversary in a context prior to armed conflict. It addresses different types of operations by initially examining parallel constructs from classical airpower theory. It goes on to analyze cyber operations in light of recently demonstrated international cyber events as well as analogues from air warfare, counterinsurgency warfare, and information operations. The analysis demonstrates that capabilities developed to exploit the unique nature of the cyber domain can be extremely persuasive if properly integrated into a well-crafted grand strategy. Effects created within the cyber domain can have real-world results that drive an opposing state's leaders to make decisions favorable to the state that is able to weild power in the domain. These operations can focus on the critical infrastructure of another state, its indigenous population, or even the leaders, themselves.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Evaluation of the Effects of Predicted Associativity on the Reliability and Performance of Mobile Ad Hoc Networks
Routing in Mobile Ad Hoc Networks (MANETs) presents unique challenges not encountered in conventional networks. Limitations in bandwidth and power as well as a dynamic network topology must all be addressed in MANET routing protocols. Predicted Associativity Routing (PAR) is a custom routing protocol designed to address reliability in MANETs. By collecting associativity information on links, PAR calculates the expected lifetime of neighboring links. During route discovery, nodes use this expected lifetime, and their neighbor's connectivity to determine a residual lifetime. The routes are selected from those with the longest remaining lifetimes. Thus, PAR attempts to extend the duration routes are active, thereby improving their reliability. PAR is compared to Ad Hoc On-Demand Distance Vector Routing (AODV) using a variety of reliability and performance metrics. Despite its focus on reliability, PAR does not provide more reliable routes. Rather, AODV produces routes which last as much as three times longer than PAR. However PAR, even with shorter lasting routes, delivers more data and has greater throughput. Both protocols are affected most by the node density of the networks. Node density accounts for 48.62% of the variation in route lifetime in AODV, and 70.66% of the variation in PAR. As node density increases from 25 to 75 nodes route lifetimes are halved, while throughput increases drastically with the increased routing overhead. Furthermore, PAR increases end-to-end delay, while AODV displays better efficiency.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Performance Analysis of Protocol Independent Multicasting-Dense Mode in Low Earth Orbit Satellite Networks
This research explored the implementation of Protocol Independent Multicasting - Dense Mode (PIM-DM) in a LEO satellite constellation. PIM-DM is a terrestrial protocol for distributing traffic efficiently between subscriber nodes by combining data streams into a tree-based structure, spreading from the root of the tree to the branches. Using this structure, a minimum number of connections are required to transfer data, decreasing the load on intermediate satellite routers. The PIM-DM protocol was developed for terrestrial systems and this research implemented an adaptation of this protocol in a satellite system. This research examined the PIM-DM performance characteristics which were compared to earlier work for On- Demand Multicast Routing Protocol (ODMRP) and Distance Vector Multicasting Routing Protocol (DVMRP) - all in a LEO satellite network environment. Experimental results show that PIM-DM is extremely scalable and has equivalent performance across diverse workloads.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

From Web1 to Web3
From Web1 to Web3 is your definitive roadmap through the current digital revolution. Authored by Ollie Bell, Nabil Hadi, and Daniel Strode, this book offers a clear, thoughtful exploration of the internet's evolution - from its humble, static beginnings to the dynamic, decentralized future that is emerging today.The journey begins with Web1, an era defined by a read- only landscape of information where the internet functioned primarily as a digital library. As time moved on, Web2 brought a seismic shift with its explosion of usergenerated content and the rise of social media, fundamentally changing how we communicate and share. However, as centralized platforms increasingly controlled our digital interactions and data, a new need arose - a need for a system that returned control to the individual.Enter Web3. In this new paradigm, blockchain technology, cryptocurrencies, decentralized finance (DeFi), non- fungible tokens (NFTs), and decentralized autonomous organizations (DAOs) converge to empower individuals with true digital ownership and control. Rather than relying on centralized institutions, Web3 leverages transparent, peer- to- peer networks to reimagine how we interact with the digital world.This book provides not only a historical perspective but also practical insights for businesses and individuals alike. Through case studies featuring leading global brands and actionable guides on navigating decentralized applications (dApps), readers gain an understanding of how businesses and individuals are already using Web3 technologies to drive innovation and create value. Whether you're an entrepreneur, investor, developer, or a digital native keen to reclaim your data and identity, this book offers the knowledge you need to adapt and thrive in this rapidly evolving landscape.Beyond the technical details, From Web1 to Web3 explores the broader cultural and economic shifts brought about by decentralization. It examines how these changes are redefining what it means to be connected and how trust is built in a world where power is shifting from centralized authorities to individual users.This book is a balanced and accessible guide, providing the context, analysis, and practical advice required to understand the present and future of the internet. Your journey into the evolving world of Web3 begins here.
Software and Critical Technology Protection Against Side-Channel Analysis Through Dynamic Hardware Obfuscation
Side Channel Analysis (SCA) is a method by which an adversary can gather information about a processor by examining the activity being done on a microchip though the environment surrounding the chip. Side Channel Analysis attacks use SCA to attack a microcontroller when it is processing cryptographic code, and can allow an attacker to gain secret information, like a crypto-algorithm's key. The purpose of this thesis is to test proposed dynamic hardware methods to increase the hardware security of a microprocessor such that the software code being run on the microprocessor can be made more secure without having to change the code. This thesis uses the Java Optimized Processor (JOP) to identify and _x SCA vulnerabilities to give a processor running RSA or AES code more protection against SCA attacks.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Mitigating Distributed Denial of Service Attacks in an Anonymous Routing Environment
Network-centric intelligence collection operations use computers and the Internet to identify threats against Department of Defense (DoD) operations and personnel, to assess the strengths and weaknesses of enemy capabilities and to attribute network events to sponsoring organizations. The security of these operations are paramount and attention must be paid to countering enemy attribution efforts. One way for U.S. information operators to avoid being linked to the DoD is to use anonymous communication systems. One such anonymous communication system, Tor, provides a distributed overlay network that anonymizes interactive TCP services such as web browsing, secure shell, and chat. Tor uses the Transport Layer Security (TLS) protocol and is thus vulnerable to a distributed denial-of-service (DDoS) attack that can significantly delay data traversing the Tor network. This research is the first to explore DDoS mitigation in the anonymous routing environment. Defending against DDoS attacks in this environment is challenging as mitigation strategies must account for the distributed characteristics of anonymous communication systems and for anonymity vulnerabilities. In this research, the TLS DDoS attack is mitigated by forcing all clients (malicious or legitimate) to solve a puzzle before a connection is completed.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Visually Managing IPsec
The United States Air Force relies heavily on computer networks to transmit vast amounts of information throughout its organizations and with agencies throughout the Department of Defense. The data take many forms, utilize different protocols, and originate from various platforms and applications. It is not practical to apply security measures specific to individual applications, platforms, and protocols. Internet Protocol Security (IPsec) is a set of protocols designed to secure data traveling over IP networks, including the Internet. By applying security at the network layer of communications, data packets can be secured regardless of what application generated the data or which protocol is used to transport it. However, the complexity of managing IPsec on a production network, particularly using the basic command-line tools available today, is the limiting factor to widespread deployment. This thesis explores several visualizations of IPsec data, evaluates the viability of using visualization to represent and manage IPsec, and proposes an interface for a visual IPsec management application to simplify IPsec management and make this powerful security option more accessible to the information warfighter.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Throughput Performance Evaluation and Analysis of Unmodified Bluetooth Devices
The Air Force relies on the application of new technologies to support and execute its mission. As new technologies develop, the integration of that technology is studied to determine the costs and benefits it may provide to the war fighter. One such emergent technology is the Bluetooth wireless protocol, used to connect a small number of devices over a short distance. The short distance is a feature that makes using the protocol desirable. However short, there is still a vulnerability to interception. This research identifies ranges at which several commercially available Bluetooth devices are usable. Various combinations of both distance and orientation are varied to determine a 360 degree map of the Bluetooth antenna. The map identifies distances at which certain throughput thresholds are available. This research shows that baseline 1 mW Bluetooth antennas are capable of throughput levels of 100 kbps at over 40 meters, which is four times the minimum distance specified in the protocol standard. The 3Com PC card was the best performing PC card, capable of throughputs at or near 100 kbps out to 40 meters. The other PC Cards tested had similar performance. The Hawking USB dongle was the best USB antenna tested, achieving throughputs of over 200 kbps in three of the four orientation, and over 150 kbps at the fourth. The 3Com dongle was a close second, the Belkin dongle a distant third, while the DLink antenna was not able to achieve 100 kbps at any distance tested.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Air Force and the Cyberspace Mission
A little over year ago, in November 2005, the Secretary of the Air Force Michael W. Wynne and Air Force Chief of Staff General T. Michael Moseley wrote a joint letter to all airmen of the Air Force. The letter defined a new mission statement which also included the concept of cyberspace. The secretary and chief defined cyberspace as including network security, data transmission and the sharing of information. It would be useful to look at how United States adversaries plan to engage us in the cyber domain as the Air Force moves toward this new frontier. This paper begins by suggesting potential areas an adversary may infiltrate cyberspace. It also includes a scenario describing China's cyberspace strategy. A brief historical look at computers, followed by a visit to today's systems, and then more importantly, an examination of future vulnerability of computer systems used throughout the Air Force is also included. A snapshot of current computer vulnerabilities within the Air Force, to include the operating systems, software and network/internet connectivity is also discussed in this paper. Although the Air Force and the Department of Defense (DOD) in general, have numerous safeguards in effect to protect systems and their networks, the DOD relies on a system that is passive when encountering cyber threats. This paper offers recommendations to consider, in the future, as the Air Force increasingly becomes reliant on computers, software, and the networks they reside on. Additionally, the time needed to develop and deploy effective defenses in cyberspace is much longer than the time required for an adversary to mount an attack.

Ten Propositions Regarding Cyberpower
This thesis is an initial attempt to clarify and further conceptualize cyberspace as an Air Force warfighting domain. This thesis follows two previous Ten Propositions works regarding airpower and spacepower, respectively written by Col Phillip S. Meilinger (1995) and Maj Michael V. Smith (2001). As the United States military explores its future regarding cyberspace operations, the time has come to frame similar propositions regarding cyberpower. Specifically, this thesis seeks to answer the question: What is the nature of cyberpower? It also tests the notion that cyberpower is simply a continuation or extension of airpower. Two points come immediately to the forefront of this work. First, cyberpower is different from airpower in that it encompasses much more than the vertical dimension of warfare. Second, cyberspace operations are quickly maturing to a point wherein propositions regarding cyberpower are worth discussing. The ten propositions presented here do not represent a complete list.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Megabyte Will Always get Through
The purpose of this monograph is to describe the future road ahead for the US Cyber community in light of the recent technical and strategic developments in the state of cyber warfare. The paper began with a realization that cyber attacks have now become weaponized, and have the ability to command computer-guided machines to destroy themselves. In effect, kinetic strikes are now possible through the means of cyber attacks. Cyber attacks have therefore become kinetic in nature. Moreover, a history of such attacks has indicated the offense is significantly more powerful than the defense, and that there have been numerous examples where attacks easily and decisively defeated defensive schemes. However, the American cyber community is not unified, has no common doctrine, budget, educational or recruiting infrastructure. The method used was to break the community down into its component parts, discuss what characteristics made cyber warfare unique, then seek like organizations. Once those organizations were identified, and analysis of what made those organizations successful was made. Conclusions were drawn and those conclusions became recommended future activities for the cyber community. An analysis of the US cyber community determined that it was a technical organization, dependent on a small number of highly skilled personnel. It had a future that could see it as a decisive role player in future conflicts, but had an insignificant past. It had to struggle for funding dollars, and theorists and doctrine writers had difficulty identifying a road ahead. This community had great resemblance to the current cyber community in China, and the US Army Air Corps in the WWI - WWII interwar period. An analysis of those organizations determined several historical facts. Domains where technology was growing at a rapid rate brought several challenges as to how to maximize the organized systematic growth of the organization. Budgets were always a contentious issue, especially whenThis work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Spear Phishing Attack Detection
This thesis addresses the problem of identifying email spear phishing attacks, which are indicative of cyber espionage. Spear phishing consists of targeted emails sent to entice a victim to open a malicious file attachment or click on a malicious link that leads to a compromise of their computer. Current detection methods fail to detect emails of this kind consistently. The SPEar phishing Attack Detection system (SPEAD) is developed to analyze all incoming emails on a network for the presence of spear phishing attacks. SPEAD analyzes the following file types: Windows Portable Executable and Common Object File Format (PE/COFF), Adobe Reader, and Microsoft Excel, Word, and PowerPoint. SPEAD's malware detection accuracy is compared against five commercially-available email anti-virus solutions. Finally, this research quantifies the time required to perform this detection with email traffic loads emulating an Air Force base network. Results show that SPEAD outperforms the anti-virus products in PE/COFF malware detection with an overall accuracy of 99.68% and an accuracy of 98.2% where new malware is involved. Additionally, SPEAD is comparable to the anti-virus products when it comes to the detection of new Adobe Reader malware with a rate of 88.79%. Ultimately, SPEAD demonstrates a strong tendency to focus its detection on new malware, which is a rare and desirable trait. Finally, after less than 4 minutes of sustained maximum email throughput, SPEAD's non-optimized configuration exhibits one-hour delays in processing files and links.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Software and Critical Technology Protection Against Side-Channel Analysis Through Dynamic Hardware Obfuscation
Side Channel Analysis (SCA) is a method by which an adversary can gather information about a processor by examining the activity being done on a microchip though the environment surrounding the chip. Side Channel Analysis attacks use SCA to attack a microcontroller when it is processing cryptographic code, and can allow an attacker to gain secret information, like a crypto-algorithm's key. The purpose of this thesis is to test proposed dynamic hardware methods to increase the hardware security of a microprocessor such that the software code being run on the microprocessor can be made more secure without having to change the code. This thesis uses the Java Optimized Processor (JOP) to identify and _x SCA vulnerabilities to give a processor running RSA or AES code more protection against SCA attacks.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Packet Analysis of Unmodified Bluetooth Communication Devices
Bluetooth technology has potential for widespread use within the Department of Defense and the Air Force. An office environment using Bluetooth technology can wirelessly connect computers, printers, and other office equipment in order to share information over short distances. The clutter and annoyance of cables connecting equipment can be eliminated. Bluetooth provides a standard interface for connection, as opposed to many different proprietary cables. The research is conducted indoors in a climate controlled environment, with minimal obstructions, to closely follow free-space signal propagation. Four different antenna orientations are used. The factors varied are the distance between devices, and the antenna orientation. This research determined that two of the four cards tested have a specific distance where a change from Data High rate packets and Data Medium rate are used.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Flexible Options for Cyber Deterrence
The idea of deterrence has existed since the beginning of humanity. The concept of deterrence became synonymous with American Cold War strategic thinking and foreign policy through the idea of mutually assured destruction. However, deterrence through punishment requires attribution, the demonstration of offensive capabilities, and an assumption of rationality. These requirements demonstrate the fallacy of Cold War deterrence applied to the cyber domain. In order to address both asymmetric threats from terrorists and the intimidation associated with nation-state peer competitors in the cyber domain, what is required is a comprehension of the challenges associated with attribution and international law. Just as important is an understanding of how extremists and nation-states use the cyber domain to conduct operations. Only then can the United States consider flexible cyber deterrent options within cyberspace.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Netwars Based Study of a Joint STARS Link-16 Network
Both secure and anti-jam resistant, the Link-16 is the primary communications channel used by the Joint Surveillance Target Attack Radar System (Joint STARS) for the exchange of real-time tactical data among various ground, air, and sea platforms of the United States of America and North Atlantic Treaty Organization forces. This research explored the effect of increasing network traffic for imagery transfer to the mean delay when operating under different network topologies. Using Network Warfare Simulation (NETWARS), three different missions were simulated to run on five network topologies having a different number of participants, different assigned time slots, and stacked nets. As a result, this study determined that the Link-16 network is able to handle the increase in network traffic, from 30 kilobits per second to 50 kilobits per second, when using multiple stacked net configurations while assigning an adequate number of time slots. However, because each participant is limited to 128 time slots per second, the increased network traffic limits the communication ability of other participants.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

WLAN CSMA/CA Performance in a Bluetooth Interference Environment
IEEE 802.11 WLANs and Bluetooth piconets both operate in the 2.4 GHz Industrial Scientific and Medical (ISM) radio band. When operating in close proximity, these two technologies interfere with each other. Current literature suggests that IEEE 802.11 (employing direct sequence spread spectrum technology) is more susceptible to this interference than Bluetooth, which uses frequency hopping spread spectrum technology, resulting in reduced throughput. Current research tends to focus on the issue of packet collisions, and not the fact that IEEE 802.11 may also delay its transmissions while the radio channel is occupied by a Bluetooth signal.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

An Analysis of Botnet Vulnerabilities
Botnets are a significant threat to computer networks and data stored on networked computers. The ability to inhibit communication between servers controlling the botnet and individual hosts would be an effective countermeasure. The objective of this research was to find vulnerabilities in Unreal IRCd that could be used to shut down the server. Analysis revealed that Unreal IRCd is a very mature and stable IRC server and no significant vulnerabilities were found. While this research does not eliminate the possibility that a critical vulnerability is present in the Unreal IRCd software, none were identified during this effort.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Simple Public Key Infrastructure Analysis Protocol Analysis and Design
Secure electronic communication is based on secrecy, authentication and authorization. One means of assuring a communication has these properties is to use Public Key Cryptography (PKC). The framework consisting of standards, protocols and instructions that make PKC usable in communication applications is called a Public Key Infrastructure (PKI). This thesis aims at proving the applicability of the Simple Public Key Infrastructure (SPKI) as a means of PKC. The strand space approach of Guttman and Thayer is used to provide an appropriate model for analysis. A Diffie-Hellman strand space model is combined with mixed strand space proof methods for proving the correctness of multiple protocols operating in the same context. The result is the public key mixed strand space model. This model is ideal for the analysis of SPKI applications operating as sub-protocols of an implementing application. This thesis then models the popular Internet Transport Layer Security (TLS) protocol as a public key mixed strand space model. The model includes the integration of SPKI certificates. To accommodate the functionality of SPKI, a new protocol is designed for certificate validation, the Certificate Chain Validation Protocol (CCV). The CCV protocol operates as a sub-protocol to TLS and provides online certificate validation. The security of the TLS protocol integrated with SPKI certificates and sub-protocols is then analyzed to prove its security properties. The results show that the modified TLS protocol exhibits the same security guarantees in isolation as it does when executing its own sub-protocols and the SPKI Certificate Chain Validation protocol.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Graph Theoretical Analysis of Network-centric Operations Using Multi-layer Models
As the Department of Defense continues its transformations to a network centric force, evaluating DoD's progression towards net-centricity remains a challenge. This research proposes to extend the Network Centric Operation Common Framework Version 2.0 (draft) with the metrics based in graph theory and, specifically addresses, among other metrics, the measurement of a net-centric force's mission effectiveness. The research incorporates the importance of understanding network topology for evaluating an environment for net-centricity and using network characteristics to help commanders assess the effects of network changes on mission effectiveness.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Strategic Deterrence in Cyberspace
This research outlines practical steps that the United States can take to improve strategic deterrence in cyberspace. The unique character of cyberspace requires tailoring of traditional deterrence strategies to fit the domain. This research uses the Deterrence Operations Joint Operating Concept (DO JOC) and the New Triad as models for organizing deterrence operations. The DO JOC focuses on tailoring deterrence operations based on the actor; but deterrence operations must be also be tailored to the uniqueness of cyberspace. The effective tailoring of deterrence operations for cyberspace will require both the application of new ways and means and the tailoring of traditional deterrence concepts to fit this new domain. Practical application of cyber strategic deterrence involves: issuance of US declaratory cyber deterrence policy; removing sanctuaries for cyber adversaries; changing US and adversary mindsets and expectations for what is permitted in cyberspace; changes to military planning in order to conduct operations in consideration of adversary cyber capability; and appreciation of the key policy tradeoffs with respect to cyber deterrence implementation. Cyberspace deterrence should include all three ways of implementing a deterrence strategy: imposing costs, denying benefits, and inducing adversary restraint. Influencing the "Consequences of Restraint" fulcrum through attribution, identity management, and incentivizing trust holds great promise for cyberspace deterrence.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Internet Protocol Over Link-16
The purpose of Link-16 is to exchange real-time tactical data among units of the United States and allied forces. Primary Link-16 functions include exchange of friendly unit position and status data, the dissemination of tactical surveillance track data, and the control/management of air, surface, and subsurface engagements. Because Link-16 will play an integral part in the network-centric Joint Battlespace Infosphere (JBI), the performance of Internet Protocol version six (IPv6) and IP Security (IPSec) over Link-16 needs to be determined. IP packets also afford additional security measures within the JBI. Using OPNET modeling software to simulate a Link-16 network, the investigation of this research revealed that the overhead from IPv6 and IPSec does not significantly affect end-to-end delay and effective throughput of the Link-16 network. As long as the encryption and authentication protocols are preprocessed, these protocols add minimal amounts of latency overhead to the Link-16 network. However, as the offered load is extended beyond the 90 % level, the overhead from the IPSec extensions begins to have more of a negative effect on the End-to-End delay and throughput.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Multi-Class Classification for Identifying JPEG Steganography Embedding Methods
Over 725 steganography tools are available over the Internet, each providing a method for covert transmission of secret messages. This research presents four steganalysis advancements that result in an algorithm that identifies the steganalysis tool used to embed a secret message in a JPEG image file. The algorithm includes feature generation, feature preprocessing, multi-class classification and classifier fusion. The first contribution is a new feature generation method which is based on the decomposition of discrete cosine transform (DCT) coefficients used in the JPEG image encoder. The generated features are better suited to identifying discrepancies in each area of the decomposed DCT coefficients. Second, the classification accuracy is further improved with the development of a feature ranking technique in the preprocessing stage for the kernel Fisher's discriminant (KFD) and support vector machines (SVM) classifiers in the kernel space during the training process. Third, for the KFD and SVM two-class classifiers a classification tree is designed from the kernel space to provide a multi-class classification solution for both methods. Fourth, by analyzing a set of classifiers, signature detectors, and multi-class classification methods a classifier fusion system is developed to increase the detection accuracy of identifying the embedding method used in generating the steganography images.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

A Study of Rootkit Stealth Techniques and Associated Detection Methods
In today's world of advanced computing power at the fingertips of any user, we must constantly think of computer security. Information is power and this power is had within our computer systems. If we can not trust the information within our computer systems then we can not properly wield the power that comes from such information. Rootkits are software programs that are designed to develop and maintain an environment in which malware may hide on a computer system after successful compromise of that computer system. Rootkits cut at the very foundation of the trust that we put in our information and subsequent power. This thesis seeks to understand rootkit hiding techniques, rootkit finding techniques and develops attack trees and defense trees in order to help us identify deficiencies in detection to further increase the trust in our information systems.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Using Prospect Theory to Investigate Decision-Making Bias Within an Information Security Context
Information security is an issue that has increased greatly in importance to bothindustry executives as well as military leadership over the past decade. In this time bothpractitioner and academic circles have researched and developed practices and process tomore effectively handle information security. Even with growth in these areas there hasbeen almost no research conducted into how decision makers actually behave. This isproblematic because information security decision makers in the Department of Defensehave been observed exhibiting risk seeking behavior when making information securitydecisions that seemingly violate accepted norms. There are presently no models in theliterature that provide sufficient insight into this phenomenon.This study used Prospect Theory, developed by Kahneman and Tversky, as aframework to develop a survey in an effort to obtain insight into how decision makersactually behave while making information security decisions.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Evaluation of the Ad Hoc On-Demand Distance Vector Routing Protocol for Mobile Ad Hoc Networks
Routing protocols designed for wired networks cannot be used in mobile ad hoc networks (MANETs) due to the dynamic topology, limited throughput, and energy constraints. New routing protocols have been designed for use in MANETs, but have not been thoroughly tested under realistic conditions such as node movement, number of sources, the presence of obstacles, and node speed.This research evaluates the performance of ad hoc on-demand distance vector routing with respect to throughput, goodput ratio, end-to-end (ETE) delay, node pair packet delivery rate, and node pair end-to-end delay. It shows these performance metrics vary significantly according to the choice of mobility model, number of sources, and the presence or absence of obstacles. The mobility model explains 68% of the variation in node pair packet delivery rate. The mobility model explains between 8% and 53% of variation in the other performance metrics. Obstacles explain between 5% and 24% of variation, and have the greatest effect on ETE delay. Finally, the number of sources explains between 8% and 72% of variation in node pair ETE delay, throughput, goodput ratio, and node pair packet delivery rate. The number of sources does not have a significant affect on ETE delay.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Insider Threat Detection Using Microsoft Log Files
Many threats to a network are not detected in a timely manner. Some are found hours or even days after the threat occurs. This research enhances threat detection in networks by parsing log data from the Windows event viewer. The data is processed in real time, and the notification of a threat results in the immediate sending of an email alertto the administrator. This notification is an imperative first step which alerts administrators of a possible threat that needs to be fully investigated. It was found that timely auditing of all components of the Microsoft Event Log, along with a script running to monitor these events on all network systems, can alert an administrator immediately of a potential threat situation on the network via email, resulting in more efficient defense tactics.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Spectral Domain RF Fingerprinting for 802.11 Wireless Devices
The increase in availability and reduction in cost of commercial communication devices (IEEE compliant such as 802.11, 802.16, etc) has increased wireless user exposure and the need for techniques to properly identify/classify signals for increased security measures. A communication device's emission includes intentional modulation that enables correct device operation. Hardware and environmental factors alter the ideal response and induce unintentional modulation e ects. If these e ects (features) are su ciently unique it becomes possible to identify a device using its ngerprint, with potential discrimination of not only manufacturers but possibly serial numbers for a given manufacturer.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Uscybercom
Even though the Department of Defense has named cyberspace as the newest domain of warfare, the United States is not adequately organized to conduct cyber war. United States Strategic Command (USSTRATCOM) is the functional combatant command responsible for cyberspace but suffers from numerous problems that prevent it from properly planning, coordinating, and conducting cyberspace operations. Among the problems facing USSTRATCOM are insufficient manning, an overly diverse mission set, and the recent failures within America's nuclear enterprise. To overcome USSTRATCOM's problems and to provide the cyber domain the prominence needed to properly protect the United States, a new functional combatant command for cyberspace must be established. This command, United States Cyberspace Command (USCYBERCOM), should be given responsibility for conducting worldwide cyber attack, defense, and intelligence. USCYBERCOM should also serve as a supporting command to the geographic combatant commanders and must establish an in-theater headquarters presence similar to the land, air, maritime, and special operations forces.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Mission Assurance
Military organizations have embedded information technology (IT) into mission processes to increase operational efficiency, improve decision-making quality, and shorten the sensor-to-shooter cycle. This IT-to-mission dependence can place the organizational mission at risk when an information incident (e.g., loss or manipulation of an information resource) occurs. Non-military organizations typically address this type of IT risk through an introspective, enterprise-wide focused risk management program that continuously identifies, prioritizes, and documents risks so control measures may be selected and implemented.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Visually Managing IPsec
The United States Air Force relies heavily on computer networks to transmit vast amounts of information throughout its organizations and with agencies throughout the Department of Defense. The data take many forms, utilize different protocols, and originate from various platforms and applications. It is not practical to apply security measures specific to individual applications, platforms, and protocols. Internet Protocol Security (IPsec) is a set of protocols designed to secure data traveling over IP networks, including the Internet. By applying security at the network layer of communications, data packets can be secured regardless of what application generated the data or which protocol is used to transport it. However, the complexity of managing IPsec on a production network, particularly using the basic command-line tools available today, is the limiting factor to widespread deployment. This thesis explores several visualizations of IPsec data, evaluates the viability of using visualization to represent and manage IPsec, and proposes an interface for a visual IPsec management application to simplify IPsec management and make this powerful security option more accessible to the information warfighter.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Megabyte Will Always get Through
The purpose of this monograph is to describe the future road ahead for the US Cyber community in light of the recent technical and strategic developments in the state of cyber warfare. The paper began with a realization that cyber attacks have now become weaponized, and have the ability to command computer-guided machines to destroy themselves. In effect, kinetic strikes are now possible through the means of cyber attacks. Cyber attacks have therefore become kinetic in nature. Moreover, a history of such attacks has indicated the offense is significantly more powerful than the defense, and that there have been numerous examples where attacks easily and decisively defeated defensive schemes. However, the American cyber community is not unified, has no common doctrine, budget, educational or recruiting infrastructure. The method used was to break the community down into its component parts, discuss what characteristics made cyber warfare unique, then seek like organizations. Once those organizations were identified, and analysis of what made those organizations successful was made. Conclusions were drawn and those conclusions became recommended future activities for the cyber community. An analysis of the US cyber community determined that it was a technical organization, dependent on a small number of highly skilled personnel. It had a future that could see it as a decisive role player in future conflicts, but had an insignificant past. It had to struggle for funding dollars, and theorists and doctrine writers had difficulty identifying a road ahead. This community had great resemblance to the current cyber community in China, and the US Army Air Corps in the WWI - WWII interwar period. An analysis of those organizations determined several historical facts. Domains where technology was growing at a rapid rate brought several challenges as to how to maximize the organized systematic growth of the organization. Budgets were always a contentious issue, especially whenThis work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Ten Propositions Regarding Cyberpower
This thesis is an initial attempt to clarify and further conceptualize cyberspace as an Air Force warfighting domain. This thesis follows two previous Ten Propositions works regarding airpower and spacepower, respectively written by Col Phillip S. Meilinger (1995) and Maj Michael V. Smith (2001). As the United States military explores its future regarding cyberspace operations, the time has come to frame similar propositions regarding cyberpower. Specifically, this thesis seeks to answer the question: What is the nature of cyberpower? It also tests the notion that cyberpower is simply a continuation or extension of airpower. Two points come immediately to the forefront of this work. First, cyberpower is different from airpower in that it encompasses much more than the vertical dimension of warfare. Second, cyberspace operations are quickly maturing to a point wherein propositions regarding cyberpower are worth discussing. The ten propositions presented here do not represent a complete list.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Analysis of Routing Worm Infection Rates on an IPV4 Network
Malicious logic, specifically worms cost network users an enormous amount of time and money. Worms, like Slammer and Code Red, infect thousands of systems and denied whole networks access to the Internet. This research examines the ability of the original Slammer worm, a Slammer based routing worm, and a new Single Slash Eight (SSE) routing worm to infect vulnerable systems within a given address space. The ability of Slammer to generate a uniform random IP addresses in a given address space is established. Finally, a comparison of the speed increase from a worm on a computing system in 2003 to those available today is performed. Both the Slammer based routing worm and the SSE routing worm spread faster than the original Slammer. The random number generator of the original Slammer worm generates a statistically uniform distribution of addresses within the range under test. Furthermore, despite the previous research into the speed of worm propagation, there is still a need to test worms on the current systems. The speed of the computing systems that the worms operated on in the past were more than three times slower than today's systems. As the speed of computer systems continue to grow, the speed of worm propagation should increase with it as their scan rates directly relate to their infection rate. As such, any inherent immunity of an IPv6 network from scanning worms should be reexamined.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Enemy at the Gateways
Every day, hackers use the Internet to "virtually" invade the borders of the United States and its critical infrastructure. National leadership must determine whether these intrusions constitute an attack or merit the declaration of a national emergency. In times of war, cyber attackers may attempt to monitor communications or disrupt information systems and other systems critical to national infrastructure. Formed in 2002, the Department of Homeland Security(DHS) holds lead agency status for many initiatives of the National Strategy to Secure Cyberspace (NSSC). The NSSC identifies critical infrastructures and key resources (CI/KR) that must be protected from physical or virtual attack. Current national strategy calls for the Department of Defense (DoD) to protect the defense industrial base (DIB), one of seven identified sectors of CI/KR. DoD components include the Office of the Secretary of Defense, the Joint Staff, the Military Services, Unified and Specified Commands, Defense Agencies, and field activities. DoD can contribute significantly to the protection of the nation from attacks directed against the United States via cyberspace by leveraging current resources and capabilities to augment ongoing initiatives and working to develop more effective homeland defense solutions. Along the way, DoD must continue working to protect the DIB from the information collection efforts of foreign intelligence services and organized crime, as well as from potential terrorist efforts to destroy or hold hostage critical information. Sensitive but unclassified (SBU) information seems to be more at risk than classified program information at this time, so current DoD efforts aim to secure the unclassified networks and databases of defense contractors. DoD can and should exceed the expectations laid out by the President of the United States in national strategy. Cooperation and information sharing will be the key.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Internet Protocol Over Link-16
The purpose of Link-16 is to exchange real-time tactical data among units of the United States and allied forces. Primary Link-16 functions include exchange of friendly unit position and status data, the dissemination of tactical surveillance track data, and the control/management of air, surface, and subsurface engagements. Because Link-16 will play an integral part in the network-centric Joint Battlespace Infosphere (JBI), the performance of Internet Protocol version six (IPv6) and IP Security (IPSec) over Link-16 needs to be determined. IP packets also afford additional security measures within the JBI. Using OPNET modeling software to simulate a Link-16 network, the investigation of this research revealed that the overhead from IPv6 and IPSec does not significantly affect end-to-end delay and effective throughput of the Link-16 network. As long as the encryption and authentication protocols are preprocessed, these protocols add minimal amounts of latency overhead to the Link-16 network. However, as the offered load is extended beyond the 90 % level, the overhead from the IPSec extensions begins to have more of a negative effect on the End-to-End delay and throughput.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

WLAN CSMA/CA Performance in a Bluetooth Interference Environment
IEEE 802.11 WLANs and Bluetooth piconets both operate in the 2.4 GHz Industrial Scientific and Medical (ISM) radio band. When operating in close proximity, these two technologies interfere with each other. Current literature suggests that IEEE 802.11 (employing direct sequence spread spectrum technology) is more susceptible to this interference than Bluetooth, which uses frequency hopping spread spectrum technology, resulting in reduced throughput. Current research tends to focus on the issue of packet collisions, and not the fact that IEEE 802.11 may also delay its transmissions while the radio channel is occupied by a Bluetooth signal.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
