The Paradox Of Social Media Security: A Study Of It Students’ Perceptions Versus Behavior On Using Facebook, Zahra Y. Alqubaiti

Master of Science in Information Technology Theses

Social media plays an essential role in the modern society, enabling people to be better connected to each other and creating new opportunities for businesses. At the same time, social networking sites have become major targets for cyber-security attacks due to their massive user base. Many studies investigated the security vulnerabilities and privacy issues of social networking sites and made recommendations on how to mitigate security risks. Users are an integral part of any security mix. In this thesis, we explore the relationship between users’ security perceptions and their actual behavior on social networking sites. Protection motivation theory (PMT), initially …

Knowledge Modeling Of Phishing Emails, Courtney Falk

Open Access Dissertations

This dissertation investigates whether or not malicious phishing emails are detected better when a meaningful representation of the email bodies is available. The natural language processing theory of Ontological Semantics Technology is used for its ability to model the knowledge representation present in the email messages. Known good and phishing emails were analyzed and their meaning representations fed into machine learning binary classifiers. Unigram language models of the same emails were used as a baseline for comparing the performance of the meaningful data. The end results show how a binary classifier trained on meaningful data is better at detecting phishing …

Ultrasonic Data Steganography, Alexander Orosz Edwards

KSU Journey Honors College Capstones and Theses

What started off as a question on the possibly of data transmission via sound above the level of human hearing evolved into a project exploring the possibility of ultrasonic data infiltration and exfiltration in an information security context. It is well known that sound can be used to transmit data as this can be seen in many old technologies, most notably and simply DTMF tones for phone networks. But what if the sound used to transmit signals was in in the ultrasonic range? It would go generally unnoticed to anyone not looking for it with tools such as a spectrum …

Empirical Analysis Of Socio-Cognitive Factors Affecting Security Behaviors And Practices Of Smartphone Users, Joseph P. Simpson

CCE Theses and Dissertations

The overall security posture of information systems (IS) depends on the behaviors of the IS users. Several studies have shown that users are the greatest vulnerability to IS security. The proliferation of smartphones is introducing an entirely new set of risks, threats, and vulnerabilities. Smartphone devices amplify this data exposure problem by enabling instantaneous transmission and storage of personally identifiable information (PII) by smartphone users, which is becoming a major security risk. Moreover, companies are also capitalizing on the availability and powerful computing capabilities of these smartphone devices and developing a bring-your-own-device (BYOD) program, which makes companies susceptible to divulgence …

An Empirical Assessment Of Employee Cyberslacking In The Public Sector, Wilnelia Hernández

CCE Theses and Dissertations

With the increasing use of the Internet, new challenges are presented to employees in the workplace. Employees spend time during work hours on non-work related activities including visiting e-commerce Websites, managing personal email accounts, and engaging in e-banking. These types of actions in the workplace are known as cyberslacking. Cyberslacking affects the employees’ productivity, presents legal concerns, and undermines the security of the organization’s network. This research study addressed the problem of cyberslacking in the public sector, by assessing the ethical severity of cyberslacking activities, as well as how employees perceived that the frequency of such activities occurred by their …

Understanding The Impact Of Hacker Innovation Upon Is Security Countermeasures, Sean M. Zadig

CCE Theses and Dissertations

Hackers external to the organization continue to wreak havoc upon the information systems infrastructure of firms through breaches of security defenses, despite constant development of and continual investment in new IS security countermeasures by security professionals and vendors. These breaches are exceedingly costly and damaging to the affected organizations. The continued success of hackers in the face of massive amounts of security investments suggests that the defenders are losing and that the hackers can innovate at a much faster pace.

Underground hacker communities have been shown to be an environment where attackers can learn new techniques and share tools pertaining …

New Secure Solutions For Privacy And Access Control In Health Information Exchange, Ahmed Fouad Shedeed Ibrahim

Theses and Dissertations--Computer Science

In the current digital age, almost every healthcare organization (HCO) has moved from storing patient health records on paper to storing them electronically. Health Information Exchange (HIE) is the ability to share (or transfer) patients’ health information between different HCOs while maintaining national security standards like the Health Insurance Portability and Accountability Act (HIPAA) of 1996. Over the past few years, research has been conducted to develop privacy and access control frameworks for HIE systems. The goal of this dissertation is to address the privacy and access control concerns by building practical and efficient HIE frameworks to secure the sharing …

Technetium: Productivity Tracking For Version Control Systems, David Leonard

Dissertations and Theses

In recent years, the City College of New York has seen its Computer Science program grow immensely, to the point of overcrowding. This has negative implications for both students and professors, particularly in introductory computer science courses in which constant feedback, iteration and collaboration with others is key to success. In this paper we propose various models for collaboration among students in all course levels using distributed version control systems and implement a secure and efficient tool for visualizing collaborative efforts by observing past work [5]. Lastly, we lay the foundation for future work around additional collaborative metrics, features and …

The Corporate Security Stratum Of Work: Identifying Levels Of Work In The Domain, Codee Roy Ludbey

Theses : Honours

Corporate security is a practicing domain and developing academic discipline that provides for the protection of people, information and assets, as well as the self-protection of organisations. Fayol (1949) articulated such an activity within organisations to be a core business function of significant importance; embedding security operations within all aspects of organisational work. This embedded nature of security within organisations has led to difficulty in the literature delineating roles and responsibilities of security practitioners; consequently leading to a nebulous understanding of security as a whole. Therefore, an investigation of the corporate security stratum of work has been undertaken to address …
