Public school districts are frequently targeted by cybercriminals to gain access to a wealth of under-protected sensitive data. As a result, information technology (IT) leaders in public school districts must implement measures to maintain the security and confidentiality of sensitive data collected and stored by their schools. This qualitative…

The need to protect confidential data stored in university enterprise information systems and to prevent infiltration through phishing cyber attacks by malicious individuals and organizations has emerged. The unfortunate target of phishing attacks is university employees and students with access to confidential information. This research specifies…

The aim of this study is to understand the Tor browser and its multiple applications as related to cybersecurity. The study also argues that most internet users are not aware of the danger they face when navigating the dark web. This research explores top executives' and specialized employees' awareness and understating of the hidden areas of…

Communication privacy is constantly under threat from Nation State Adversaries (NSA). This has led many platforms, such as Facebook and Apple, to implement secure conversation cryptographic protocols in their messaging applications. However, many of the protocols do not provide provable security and do not provide other security guarantees about…

Academic institutions hold important information about students, faculty, and staff members. Hackers target academic institutions to access this information for criminal activities such as identity theft. This study was conducted to examine information confidentiality and cybersecurity in academic institutions. It targeted employees' training…

The online communication landscape has changed significantly from the early days of the Internet. In most developed countries, people are constantly connected through the Internet to almost everyone else in their lives, everywhere they go. The Internet makes their lives more convenient, but unintentional exposure of personal information to…

Current networking architectures and communication protocols used for Wireless Sensor Networks (WSNs) have been designed to be energy efficient, low latency, and long network lifetime. One major issue that must be addressed is the security in data communication. Due to the limited capabilities of low cost and small sized sensor nodes, designing…

Sender anonymity in Location-based services (LBS) refers to hiding the identity of a mobile device user who sends requests to the LBS provider for services in her proximity (e.g. "find the nearest gas station etc."). The goal is to keep the requester's interest private even from attackers who (via hacking or subpoenas) gain access to the LBS…

Given the lack of computer diffusion studies in the Caribbean, and coupled with the necessity to understand Jamaica in efforts to get a clearer global representation of the digital divide, this study takes an exploratory approach and examines the differences of the computer technology adoption and diffusion attitudes and viewpoints between the…

Wireless Sensor Networks (WSNs) have unique characteristics which constrain them; including small energy stores, limited computation, and short range communication capability. Most traditional security algorithms use cryptographic primitives such as Public-key cryptography and are not optimized for energy usage. Employing these algorithms for the…

"End-to-End (E2E)" voting systems provide cryptographic proof that the voter's intention is captured, cast, and tallied correctly. While E2E systems guarantee integrity independent of software, most E2E systems rely on software to provide confidentiality, availability, authentication, and access control; thus, end-to-end integrity is not…

In recent years, many health care organizations have begun to take advantage of computerized information systems to facilitate more effective and efficient management and processing of information. However, commensurate with the vastly innovative enhancements that computer technology has contributed to traditional paper-based health care…

WSNs are susceptible to a variety of attacks. These attacks vary in the way they are performed and executed; they include but not limited to node capture, physical tampering, denial of service, and message alteration. It is of paramount importance to protect gathered data by WSNs and defend the network against illegal access and malicious…

Location is fundamental information in Vehicular Ad-hoc Networks (VANETs). Almost all VANET applications rely on location information. Therefore it is of importance to ensure location information integrity, meaning that location information is original (from the generator), correct (not bogus or fabricated) and unmodified (value not changed). We…

Today's interconnected technical environment creates unprecedented opportunities while simultaneously introducing risks. With economic, social and personal interactions increasingly occurring in technology-mediated settings new vulnerabilities are continually being introduced. This dissertation seeks to improve extant understanding of how…
