Social Media Text Mining Framework For Drug Abuse: An Opioid Crisis Case Analysis, Tareq Nasralah
Social Media Text Mining Framework For Drug Abuse: An Opioid Crisis Case Analysis, Tareq Nasralah
Masters Theses & Doctoral Dissertations
Social media is considered as a promising and viable source of data for gaining insights into various disease conditions, patients’ attitudes and behaviors, and medications. The daily use of social media provides new opportunities for analyzing several aspects of communication. Social media as a big data source can be used to recognize communication and behavioral themes of problematic use of prescription drugs. Mining and analyzing such media have challenges and limitations with respect to topic deduction and data quality. There is a need for a structured approach to efficiently and effectively analyze social media content related to drug abuse in …
Mirai Bot Scanner Summation Prototype, Charles V. Frank Jr.
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
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 …
Advanced Code-Reuse Attacks: A Novel Framework For Jop, Bramwell J. Brizendine
Advanced Code-Reuse Attacks: A Novel Framework For Jop, Bramwell J. Brizendine
Masters Theses & Doctoral Dissertations
Return-oriented programming is the predominant code-reuse attack, where short gadgets or borrowed chunks of code ending in a RET instruction can be discovered in binaries. A chain of ROP gadgets placed on the stack can permit control flow to be subverted, allowing for arbitrary computation. Jump-oriented programming is a class of code-reuse attack where instead of using RET instructions, indirect jumps and indirect calls are utilized to subvert the control flow. JOP is important because can allow for important mitigations and protections against ROP to be bypassed, and some protections against JOP are imperfect. This dissertation presents a design science …
