Flying and Fighting in Cyberspace
This research paper develops the foundation for a new military operating concept to "fight the net" in support of 8th Air Force requirements and stand-up as the new Cyber Command. It applies the Air Force Concept Development framework to examine cyberspace as a newly designated warfare domain, and proposes cyber capabilities and effects that the Air Force should develop and apply as it seeks to execute its mission in cyberspace. Before the Air Force can effectively lead in the cyber domain, it must first fully characterize cyber conditions, threats, and vulnerabilities, and clearly define how and where it can contribute to the national cyberspace strategy. Once the Air Force accomplishes these tasks, it can then focus on the nature of war in the cyber domain and consider the implications for military doctrine and operations. In order to successfully build capability and capacity for operating in cyberspace, the Air Force needs to institutionalize "cyber-mindedness" to underpin organizational, research and development, and human capital investments that the Air Force needs "to fly and fight" effectively in 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.

Heuristically Driven Search Methods for Topology Control in Directional Wireless Hybrid Networks
Information and Networked Communications play a vital role in the everyday operations of the United States Armed Forces. This research establishes a comparative analysis of the unique network characteristics and requirements introduced by the Topology Control Problem (also known as the Network Design Problem). Previous research has focused on the development of Mixed-Integer Linear Program (MILP) formulations, simple heuristics, and Genetic Algorithm (GA) strategies for solving this problem. Principal concerns with these techniques include runtime and solution quality. To reduce runtime, new strategies have been developed based on the concept of flow networks using the novel combination of three well-known algorithms; knapsack, greedy commodity filtering, and maximum flow. The performance of this approach and variants are compared with previous research using several network metrics including computation time, cost, network diameter, dropped commodities, and average number of hops per commodity. The results conclude that maximum flow algorithms alone are not quite as effective as previous findings, but are at least comparable and show potential for larger networks.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Applying Automated Theorem Proving to Computer Security
While more and more data is stored and accessed electronically, better access control methods need to be implemented for computer security. Formal modelling and analysis have been successfully used in certain areas of computer systems, such as verifying the security properties of cryptographic and authentication protocols. However, formal models for computer systems in cyberspace, like networks, have hardly advanced. A highly regarded graduate textbook cites the Take-Grant model created in 1977 as one of the "current" examples of security modelling and analysis techniques. This model is rarely used in practice though. This research implements the Take-Grant Protection model's four de jure rules and Can Share predicate in the Prototype Veri cation System (PVS) which automates model checking and theorem proving. This facilitates the ability to test a given Take-Grant model against many systems which are modelled using digraphs. Two models, one with error checking and one without, are created to implement take-grant rules. The rst model that does not have error checking incorporated requires manual error checking. The second model uses recursion to allow for the error checking. The Can Share theorem requires further development.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Engaging Cyber Communities
There are 1.7 billion Internet users worldwide as of October, 2009 and growing. The dramatic growth in online users in conjunction with the influence of social communities in cyberspace is having an effect in current and future international affairs. Despite the growing amount of activity performed by social groups in cyberspace, the US military remains focused on technology centric operations such as computer network attack and computer network defense. This leads to the question of whether the US military is missing an opportunity by not focusing on online social communities. This research performed a problem and solutions methodology to investigate this question. The research came up with the criteria of value and risk to analyze whether the US military should engage cyber communities. The results of this study suggest engaging online communities can augment the technology-centric solutions. Engaging online communities can help to degrade, deceive, and exploit adversaries operations in cyberspace. Engaging online communities can also influence and help respond to social groups' issues and concerns. Without responding or influencing these groups they are left to their own vagaries as well as negative and adversarial influence. There are risks associated with engaging online communities due to the ubiquitous reach of cyberspace. An ill-conceived comment, text, or video can be sent globally and have a negative impact to objectives and reputation. However, this study finds applying controls and rules of engagement in undertaking these operations can mitigate the risks. Thus, the US military needs to develop these capabilities and engage social communities in 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.

Non-Reputable Identity Management and Information Access Technologies for Improved Cyberspace Agility by 2035
The military's use of cyberspace as a warfighting domain in current operations is vulnerable to hackers and malware. Today's cyber defense strategy is based on trust and perimeter boundaries. This strategy provides the DoD with little room for strategic or tactic errors and exposes our information superiority advantages to unnecessary risk. Emerging threats are becoming more sophisticated and organized, eroding the US's asymmetric advantage in cyberspace. By 2035, the emerging threats posed by insider threats, artificial intelligence and nation-states such as China will require game-changing innovations to defend cyberspace. The goal of this research paper is to propose an identity management and information access solution capable of mitigating emerging threats to military cyberspace operations in the year 2035. This solution requires that eight major technical challenges be overcome. This paper answers the following question for DoD strategic planners: What technologies and programs should the DoD invest in today in order to mitigate emerging threats to freedom of action in cyberspace by 2035? It answers this question by surveying the existing operational environment and comparing that with three of the most probable emerging threats to cyber operations between now and 2035. Finally, the paper highlights a potential solution to these threats given current capabilities and uses backcasting to identify the required variables, policy changes, and technology challenges.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Organization of Cyberspace Forces
Forces that establish, sustain, manage, or operate in cyberspace are cyberspace forces. These forces generate first order effects "in" cyberspace. This paper seeks to provide one answer to the problem: how should cyberspace forces be organized? The research methodology is problem-solution. Four categories of criteria are used to evaluate the current cyberspace organization and a proposed alternative organization. The evaluation criteria are strategy and employment, cyberspace environment, integration, and organization/culture. This paper finds that the current cyberspace force organization is focused too much on presenting forces to USSTRATCOM and too little to Geographic Combatant Commanders (GCCs). Additionally, cyberspace forces concentrated in one MAJCOM prevent cyberspace capabilities from being directly integrated with Falconer Air and Space Operations Centers across the Air Force. The paper concludes that cyberspace forces should be organized in standardized "composite cyberspace wings" and groups, and be assigned to virtually all Component-Numbered Air Forces. Based on the evaluation criteria, cyberspace forces organized in a balanced manner that provide both global effects through USSTRATCOM and theater effects for GCCs are more likely to succeed.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Dominating Networks in Cyberspace
Recognized as an equal to the air, land, sea and space domains, US military operators must gain dominance over cyberspace, in order to maintain its superior edge in military operations throughout the world. Cyberspace "dominance" over computer networks can be achieved, but only in providing support for freedom of action to friendly forces, within the other domains. Doctrine played an important role in defining the fundamental idea of cyber dominance. In addition, an extensive literature review of books, reports and recent articles from the Internet security sites provided the background on cyber threats in the world and the laws that governed military operations in cyberspace. The paper culminates in applying this information in a scenario of a cyber attack from China on the US. It shows the effects a network attack could have and proves how cyber dominance can be achieved.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

DoD Role for Securing United States Cyberspace
The cyber attacks on Estonia in late April and the early weeks of May 2007 significantly crippled the country, preventing it from performing banking, communications, news reporting, government transactions and command and control activities. Estonia is considered a "Wired Society", much like the United States. Both countries rely on the cyberspace infrastructure economically and politically. Estonia sought assistance outside the country to recover from and to address the attacks. The cyber attacks on Estonia focused world-wide attention on the effects that cyberspace attacks could have on countries. If a cyber attack of national significance occurred against the United States, what would the United States do? The Department of Defense is responsible for protecting the nation and its geographical boundaries from attack, but what is DoD's role for securing the United States' cyberspace? Research was conducted by studying national orders, strategies, policies plans, and doctrine to determine DoD's role for securing the United States' 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.

Early Warning and Prediction of Internet Attacks and Exploits
A safe, secure and functional information network is vital in today's Air Force net centric environment. Information is more critical today than it has ever been. As more operational functions are placed in cyber space and greater computing power becomes available to everyone, keeping these networks safe and secure is an almost unattainable task. Network security entails Intrusion Detection Security, but another form of security or "insecurity" is quickly gaining attention. Honeypots allow the black hat community to attack and penetrate non-production systems. By monitoring and studying these attacks, network defenders can develop better Information Assurance tactics and procedures to defend their networks. The ability to quickly analyze only those data packets predicted to be an exploit and disregard the remaining packets is crucial in today's overworked environment. Using an accredited Honeypot, an Exploit Prediction System (EPS) is developed using a decision-tree matrix. The EPS provides an excellent tool in choosing only those data packets needing further analysis. The EPS employs as few criterion needed for successful prediction. The log data coming into the honeypot is not filtered and all incoming log data is captured, interpreted and categorized.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Empowering Marine Corps System Administrators
Organizations cannot protect the integrity, confidentiality, and availability of information in today's highly networked systems environment without ensuring that System Administrators are properly trained and meet a minimum standard that is enforced enterprise-wide. Only with this ubiquitous benchmark training, will the System Administrators roles and responsibilities become synchronous to achieving Defense in Depth in the IT realm. The goal of this research is to analyze Marine Corps training methods to identify viable solutions that will produce consistent skill sets and meet requirements set forth in mandates from DoD.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 Evaluation and Analysis of Effective Range and Data Throughput for Unmodified Bluetooth Communication Devices
The DoD and the Air Force continually seek to incorporate new technology in an effort to improve communication, work effectiveness, and efficiency. Office devices utilizing Bluetooth technology simplify device configuration and communication. They provide a means to communicate wirelessly over short distances thereby eliminating the need for different vendor specific cables and interfaces. One of the key concerns involved in incorporating new communication technology is security; the fundamental security concern of wireless communication is interception. Studies focusing on IEEE 802.11b have shown vulnerability zones around many DoD installations that reflect the ranges at which wireless communications using the 802.11b standard can be intercepted. This research identifies the vulnerability zones in which Bluetooth transmissions can potentially be intercepted. Specifically, the orientation of Bluetooth device antenna and the distance between devices are varied to determine ranges at which set levels of throughput can be achieved for a specific device configuration. Throughput ranges are then mapped to graphically reflect vulnerability zones. This research shows that the range at which Bluetooth communication can occur with unmodified devices is more than twice that of the minimum standard of 10 m outlined in the core specification without degradation of the best-case throughput level measured. It is expected that the throughput ranges could be greatly extended with some device modification. This research shows that the security risk associated with interception of Bluetooth communications is legitimate and warrants further study.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 TCP Degradation Over Intermittent Link Failures Using Intermediate Buffers
This thesis addresses the improvement of data transmission performance in a challenged network. It is well known that the popular Transmission Control Protocol degrades in environments where one or more of the links along the route is intermittently available. To avoid this degradation, this thesis proposes placing at least one node along the path of transmission to buffer and retransmit as needed to overcome the intermittent link. In the four-node, three-link testbed under particular conditions, file transmission time was reduced 20 fold in the case of an intermittent second link when the second node strategically buffers for retransmission opportunity.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Written in a distinctly cranky, humorous, and often cynical voice by an experienced programmer and LLM tool builder ("Cranky Man"), it aims to cut through AI hype and technical jargon to provide hard-won lessons learned from extensive experimentation and failure.The author will guide you through the minefield of AI terms and concepts and you will emerge at the other side, preferably still with your sanity intact.So, what can you expect from this book?A solid grounding in the theory of Large Language Models, without getting bogged down in the details and math. You'll learn about the different types of models, quantization, how to choose the right one for the job, and how to train it.What all of the rank, alpha, batch_size or gradient accumulation actually do. In a plain language.You'll discover the tricks of the trade, the secrets of data collection, preparation and augmentation.You'll learn how to set up and use the hardware and software; even how to build your own multi-GPU AI supercomputer.How to read the tea leaves: Demystify the training process by learning to interpret those inscrutable loss graphs, and tell when your model is actually learning, when it's just memorizing the training data, and when it's blissfully and expensively dead.How to sidestep the pitfalls: Benefit from Cranky Man's hard-won experience and avoid the most common CUDA errors, Python tantrums and soul-crushing weight of unmet expectations.The author, F.P. HAM aka Cranky Man, is a real-world senior programmer. He didn't just use the training tools, he contributed and built many of them! From the rage-coded Training PRO, to the VirtualLora, Twinbook, Playground or Storycrafter.Cranky Man has been there, done that, got the T-shirt, the GPU burn marks and the electricity bills to prove it!This book is the result of thousands of experiments, the successes, the near misses, the total disasters. It is the story of one man's obsessive quest to create the ultimate AI model.So, there you have it. The definitive guide to training your own Large Language Model. If you're serious about getting into AI, this is the book for you. It's the one book that Cranky Man wished he'd had when he started out. He says it would have saved him a small country GDP-worth in electricity.

Multicast Algorithms for Mobile Satellite Communication Networks
With the rise of mobile computing and an increasing need for ubiquitous high speed data connections, Internet-in-the-sky solutions are becoming increasingly viable. To reduce the network overhead of one-to-many transmissions, the multicast protocol has been devised. The implementation of multicast in these Low Earth Orbit (LEO) constellations is a critical component to achieving an omnipresent network environment. This research examines the system performance associated with two terrestrial-based multicast mobility solutions, Distance Vector Multicast Routing Protocol (DVMRP) with mobile IP and On Demand Multicast Routing Protocol (ODMRP). These protocols are implemented and simulated in a six plane, 66 satellite LEO constellation. Each protocol was subjected to various workload, to include changes in the number of source nodes and the amount of traffic generated by these nodes. Results from the simulation trials show the ODMRP protocol provided greater than 99% reliability in packet deliverability, at the cost of more than 8 bits of overhead for every 1 bit of data for multicast groups with multiple sources. In contrast, DVMRP proved robust and scalable, with data-to-overhead ratios increasing logarithmically with membership levels. DVMRP also had less than 70 ms of average end- to-end delay, providing stable transmissions at high loading and membership levels. Due to the fact that system performance metric values varied as a function of protocol, system design objectives must be considered when choosing a protocol for implementation.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.

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.

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.

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.

What Senior Leaders Need to Know About Cyberspace
What must senior security leaders know about cyberspace to transform their organizations and make wise decisions? How does the enduring cyberspace process interact with and transform organizations, technology, and people, and, in turn, how do they transform cyberspace itself? To evaluate these questions, this essay establishes the enduring nature of the cyberspace process and compares this relative constant to transformation of organizations and people. Each section discussing these areas provides an assessment of their status as well as identifies key issues for senior security leaders to comprehend now and work to resolve in the future. Specific issues include viewing cyberspace as a new strategic common akin to the sea, comparing effectiveness of existing hierarchies in achieving cybersecurity against networked adversaries, and balancing efficiency and effectiveness of security against the universal laws of privacy and human rights.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 Artificial Immune System-Inspired Multiobjective Evolutionary Algorithm With Application to the Detection of Distributed Computer Network Intrusions
Today's predominantly-employed signature-based intrusion detection systems are reactive in nature and storage-limited. Their operation depends upon catching an instance of an intrusion or virus after a potentially successful attack, performing post-mortem analysis on that instance and encoding it into a signature that is stored in its anomaly database. The time required to perform these tasks provides a window of vulnerability to DoD computer systems. Further, because of the current maximum size of an Internet Protocol-based message, the database would have to be able to maintain 25665535 possible signature combinations. In order to tighten this response cycle within storage constraints, this thesis presents an Artificial Immune System-inspired Multiobjective Evolutionary Algorithm intended to measure the vector of tradeoff solutions among detectors with regard to two independent objectives: best classification fitness and optimal hypervolume size. Modeled in the spirit of the human biological immune system and intended to augment DoD network defense systems, our algorithm generates network traffic detectors that are dispersed throughout the network.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Virtualization Technology Applied to Rootkit Defense
This research effort examines the idea of applying virtualization hardware to enhance operating system security against rootkits. Rootkits are sets of tools used to hide code and/or functionality from the user and operating system. Rootkits can accomplish this feat through using access to one part of an operating system to change another part that resides at the same privilege level. Hardware assisted virtualization (HAV) provides an opportunity to defeat this tactic through the introduction of a new operating mode. Created to aid operating system virtualization, HAV provides hardware support for managing and saving multiple states of the processor. This hardware support overcomes a problem in pure software virtualization, which is the need to modify guest software to run at a less privileged level. Using HAV, guest software can operate at the pre-HAV most privileged level. This thesis provides a plan to protect data structures targeted by rootkits through unconventional use of HAV technology to secure system resources such as memory. This method of protection will provide true real-time security through OS attack prevention, rather than reaction.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
