    OBFUSCATION, STEALTH, AND NON-ATTRIBUTION IN RED TEAM TOOLS

    No full text
    Current automated red teaming tools are limited in their ability to emulate advanced persistent threat (APT) behaviors. Supporting such behaviors in automated security assessments and tools can be helpful for improving organizations’ cyber defense preparedness. This research enhances the Cyber Automated Red Team Tool (CARTT) by integrating advanced evasion techniques to better simulate sophisticated cyber threats. By incorporating Metasploit Framework evasion modules and new custom Internet Control Message Protocol (ICMP) and Domain Name System (DNS) evasion capabilities into CARTT, its ability to evade detection by common security controls is significantly improved. The research demonstrates how obfuscation, stealth, and non-attribution techniques can be effectively automated into red teaming tools. The enhanced CARTT was tested in a simulated operational environment, which demonstrated its effectiveness in identifying vulnerabilities and assessing the robustness of security measures. Results of the research showed successful evasion of antivirus detection systems and covert data exfiltration using the newly implemented techniques. The enhanced CARTT will enable network managers as well as cybersecurity professionals to conduct more thorough evaluations of defense mechanisms against sophisticated threats, ultimately strengthening overall cybersecurity postures.Distribution Statement A.

    USMC Manpower Models Modernization II

    No full text
    This project builds on our previous work in support of an FY22 Naval Research Program project (Seagren et al., 2022). The primary objective of this project is to determine the feasibility and effectiveness of a more automated process to more accurately account for all active-duty personnel gains and losses by month and facilitate the inclusion of this information in various models and processes. We develop a machine learning version of the Enlisted End-Strength Planning Model (ESPM) and compare its performance to the legacy process. Ultimately, we find that it is possible to develop and implement a machine learning approach that effectively forecasts base NEAS attrition in a managerially useful manner. In fact, evidence suggests that the machine learning models may dramatically outperform the legacy methods and that these findings are robust across fiscal years. However, resources required to develop the machine learning models include significant time on a High-Performance Computer, which may not be practical for the topic sponsor. While we find that the machine learning models perform well, the benefits relative to the legacy model and process likely do not justify the effort given current constraints of computing power.Approved for public release; distribution is unlimited.This research is supported by funding from the Naval Postgraduate School, Naval Research Program (PE0605853N/2098). https://nps.edu/nrpChief of Naval Operations (CNO)Naval Postgraduate School, Naval Research Program, Headquarters Marine Corps, Manpower & Reserve Affair

    The Naval Reserve Officer Training Corps (NROTC) program is essential for developing future leaders for the United States Navy and Marine Corps. This study aims to analyze and understand the factors contributing to midshipman attrition within the NROTC program, utilizing a dataset of over 5,000 midshipmen who enrolled and subsequently left the program between 2012 and the present. Statistical techniques and machine learning algorithms, including logistic regression, random forests, gradient boosting machines, K-Nearest Neighbors (KNN), and Naive Bayes, were used to identify key predictors of attrition. The analysis showed higher dropout rates at certain institutions and during specific periods, underscoring the need for targeted interventions and time-informed counseling strategies. Gender differences were also noted, with females more likely to leave due to physical reasons and males due to academic and disciplinary issues, suggesting the importance of gender-specific support systems. Although machine learning models showed moderate improvements in predictive accuracy, their effectiveness was limited, in part due to imbalanced data and the complexity of human factors.Distribution Statement A.

    LOCAL DESCRIPTION OF FRICTIONAL WEAKENING IN VIBRATED GRANULAR SHEAR FLOWS

    Get PDF
    The rheology of vibrated granular shear flows is a key missing piece for modeling and predicting landslides, earthquakes, and more. In this thesis, we use computer simulations written in the Large-scale Atomic/Molecular Multiprocessor Parallel Simulator (LAMMPS) language to study frictional properties of vibrated granular shear flows subjected to externally applied vibrations at the lower boundary. Based on previous dimensional analysis and the Discrete Element Method (DEM) simulations from LAMMPS, we examine frictional weakening at the local grain-scale, correlating stress, contact fabric, and force fabric tensors with fluctuations in grain velocities and system friction . This thesis makes progress toward an end goal of writing down a closed constitutive law for vibrated granular shear flows that could solve for more complex geometries that currently can only be solved with nonlocal models.

    IMPLEMENTATION OF DECENTRALIZED UNMANNED SURFACE VEHICLE SWARM CONTROL

    No full text
    Algorithms for swarm control of unmanned surface vessels (USV) normally require a communication network utilizing radio frequency (RF) to determine range and bearing between vehicles to maintain formation. The RF signals, either between USVs or between each USV and a centralized swarm controller, are vulnerable to detection and disruption by enemy actions, thus preventing typical methods of swarm formation control. This research decentralizes an existing control algorithm by simulating USVs with computer vision capable of determining range and bearing to fellow USVs in the swarm. Performance of the decentralized control algorithm will be analyzed to determine the impact of simulated cameras with different fields of view, as well as different desired swarm behaviors.Distribution Statement A.

    The COVID-19 global pandemic has brought heightened awareness to the challenges that biological events can pose for emergency medical service providers. This research seeks to produce policy guidance to create optimal pandemic preparedness strategies for the Phoenix Fire Department and its regional partners. Utilizing a design thinking process, the research engaged focus groups in a series of sessions designed to understand and define pandemic response challenges, leading to possible solutions. Focus group findings revealed that the department faced multifaceted issues in pandemic preparation, ranging from equipment and personnel decontamination to inter-agency support coordination. However, the Phoenix Fire Department also demonstrated robust capabilities in confronting past challenges. The inherent unpredictability and severity of pandemics necessitate preemptive preparation, anchored by the prioritization of accountability and thorough planning. It is recommended that the Phoenix Fire Department establish a specialized pandemic preparedness group dedicated to drafting and updating a comprehensive pandemic preparedness plan. Incorporating a continual review mechanism, this plan would benefit from a pandemic preparedness audit tool, ensuring iterative improvements through regular testing, integration of the latest knowledge, and lessons learned.Distribution Statement A.

    MASTERING THE DIGITAL ART OF WAR: DEVELOPING INTELLIGENT COMBAT SIMULATION AGENTS FOR WARGAMING USING HIERARCHICAL REINFORCEMENT LEARNING

    No full text
    In today’s rapidly evolving military landscape, advancing artificial intelligence (AI) in support of wargaming becomes essential. Despite reinforcement learning (RL) showing promise for developing intelligent agents, conventional RL faces limitations in handling the complexity inherent in combat simulations. This dissertation proposes a comprehensive approach, including targeted observation abstractions, multi-model integration, a hybrid AI framework, and an overarching hierarchical reinforcement learning (HRL) framework. Our localized observation abstraction using piecewise linear spatial decay simplifies the RL problem, enhancing computational efficiency and demonstrating superior efficacy over traditional global observation methods. Our multi-model framework combines various AI methodologies, optimizing performance while still enabling the use of diverse, specialized individual behavior models. Our hybrid AI framework synergizes RL with scripted agents, leveraging RL for high-level decisions and scripted agents for lower-level tasks, enhancing adaptability, reliability, and performance. Our HRL architecture and training framework decomposes complex problems into manageable subproblems, aligning with military decision-making structures. Although initial tests did not show improved performance, insights were gained to improve future iterations. This study underscores AI’s potential to revolutionize wargaming, emphasizing the need for continued research in this domain.Distribution Statement A.
