Evaluating The Impacts Of Detecting X.509 Covert Channels, Cody Welu Mar 2019

Evaluating The Impacts Of Detecting X.509 Covert Channels, Cody Welu

Masters Theses & Doctoral Dissertations

This quasi-experimental before-and-after study examined the performance impacts of detecting X.509 covert channels in the Suricata intrusion detection system. Relevant literature and previous studies surrounding covert channels and covert channel detection, X.509 certificates, and intrusion detection system performance were evaluated. This study used Jason Reaves’ X.509 covert channel proof of concept code to generate malicious network traffic for detection (2018). Various detection rules for intrusion detection systems were created to aid in the detection of the X.509 covert channel. The central processing unit (CPU) and memory utilization impacts that each rule had on the intrusion detection system was studied and …


Mirai Bot Scanner Summation Prototype, Charles V. Frank Jr. Mar 2019

Mirai Bot Scanner Summation Prototype, Charles V. Frank Jr.

Masters Theses & Doctoral Dissertations

The Mirai botnet deploys a distributed mechanism with each Bot continually scanning for a potential new Bot Victim. A Bot continually generates a random IP address to scan the network for discovering a potential new Bot Victim. The Bot establishes a connection with the potential new Bot Victim with a Transmission Control Protocol (TCP) handshake. The Mirai botnet has recruited hundreds of thousands of Bots. With 100,000 Bots, Mirai Distributed Denial of Service (DDoS) attacks on service provider Dyn in October 2016 triggered the inaccessibility to hundreds of websites in Europe and North America (Sinanović & Mrdovic, 2017). A month …


Flashlight In A Dark Room: A Grounded Theory Study On Information Security Management At Small Healthcare Provider Organizations, Gerald Auger Mar 2019

Flashlight In A Dark Room: A Grounded Theory Study On Information Security Management At Small Healthcare Provider Organizations, Gerald Auger

Masters Theses & Doctoral Dissertations

Healthcare providers have a responsibility to protect patient’s privacy and a business motivation to properly secure their assets. These providers encounter barriers to achieving these objectives and limited academic research has been conducted to examine the causes and strategies to overcome them. A subset of this demographic, businesses with less than 10 providers, compose a majority 57% of provider organizations in the United States. This grounded theory study provides exploratory findings, discovering these small healthcare provider organizations (SHPO) have limited knowledge on information technology (IT) and information security that results in assumptions and misappropriations of information security implementation, who is …


A Malware Analysis And Artifact Capture Tool, Dallas Wright Mar 2019

A Malware Analysis And Artifact Capture Tool, Dallas Wright

Masters Theses & Doctoral Dissertations

Malware authors attempt to obfuscate and hide their execution objectives in their program’s static and dynamic states. This paper provides a novel approach to aid analysis by introducing a malware analysis tool which is quick to set up and use with respect to other existing tools. The tool allows for the intercepting and capturing of malware artifacts while providing dynamic control of process flow. Capturing malware artifacts allows an analyst to more quickly and comprehensively understand malware behavior and obfuscation techniques and doing so interactively allows multiple code paths to be explored. The faster that malware can be analyzed the …


Matching Possible Mitigations To Cyber Threats: A Document-Driven Decision Support Systems Approach, Martha Wagner Mcneil Mar 2019

Matching Possible Mitigations To Cyber Threats: A Document-Driven Decision Support Systems Approach, Martha Wagner Mcneil

Masters Theses & Doctoral Dissertations

Cyber systems are ubiquitous in all aspects of society. At the same time, breaches to cyber systems continue to be front-page news (Calfas, 2018; Equifax, 2017) and, despite more than a decade of heightened focus on cybersecurity, the threat continues to evolve and grow, costing globally up to $575 billion annually (Center for Strategic and International Studies, 2014; Gosler & Von Thaer, 2013; Microsoft, 2016; Verizon, 2017). To address possible impacts due to cyber threats, information system (IS) stakeholders must assess the risks they face. Following a risk assessment, the next step is to determine mitigations to counter the threats …
