Cloud computing may provide cost benefits for organizations by eliminating the overhead costs of software, hardware, and maintenance (e.g., license renewals, upgrading software, servers and their physical storage space, administration along with funding a large IT department). In addition to the promised savings, the organization may require…

The major challenges facing resource constraint wireless devices are error resilience, security and speed. Three joint schemes are presented in this research which could be broadly divided into error correction based and cipher based. The error correction based ciphers take advantage of the properties of LDPC codes and Nordstrom Robinson code. A…

Online education and computer-assisted instruction (CAI) have existed for years, but few general tools exist to help instructors create and evaluate lessons. Are these tools sufficient? Specifically, what elements do instructors want to see in online testing tools? This study asked instructors from various disciplines to identify and evaluate the…

With today's high demand for online applications and services running on the Internet, software has become a vital component in our lives. With every revolutionary technology comes challenges unique to its characteristics; for online applications, security is one huge concern and challenge. Currently, there are several schemes that address…

This paper describes a survey of online learning which attempts to determine online learning providers' awareness of potential security risks and the protection measures that will diminish them. The authors use a combination of two methods: blog mining and a traditional literature search. The findings indicate that, while scholars have…

Courses in Information Technology Ethics are often designed as discussion-intensive courses where case studies are introduced and evaluated using ethical theories. Although many of the case studies directly apply to our students' online lives, the stories can sometimes seem too far removed from their own experiences. While we read the news…

This dissertation consists of three essays that examine, in three specific contexts, issues related to pricing of information goods and services. As the ability to measure technology resource usage gets easier with increased connectivity, the question whether a technology resource should be priced by the amount of the resource used or by the…

Where does privacy belong in the college/university ecosystem, and what should its relationship be with security and compliance? Are the three areas best kept separate and distinct? Should there be some overlap? Or would a single office, officer, and/or reporting line enable a big picture of the whole? This article examines several of the campus…

Increasing complexity and sophistication of ever evolving information technologies has spurred unique and unprecedented challenges for organizations to protect their information assets. Companies suffer significant financial and reputational damage due to ineffective information technology security management, which has extensively been shown to…

Botnets remain a potent threat due to evolving modern architectures, inadequate remediation methods, and inaccurate measurement techniques. In response, this research exposes the architectures and operations of two advanced botnets, techniques to enumerate infected hosts, and pursues the scientific refinement of infected-host enumeration data by…

Hands-on experiments are essential for computer network security education. Existing laboratory solutions usually require significant effort to build, configure, and maintain and often do not support reconfigurability, flexibility, and scalability. This paper presents a cloud-based virtual laboratory education platform called V-Lab that provides a…

In today's society, educational opportunities have evolved beyond the traditional classroom setting. Most universities have implemented virtual learning environments in an effort to provide more opportunities for potential or current students seeking alternative and more affordable learning solutions. "User-Centered Design Strategies for…

With increasing demand of mobile devices and cloud computing, it becomes increasingly important to develop efficient mobile application and its secured backend, such as web applications and virtualization environment. This dissertation reports a systematic study of mobile application development and the security issues of its related backend. …

The need to maintain an unpolluted learning environment is no easy task for schools and districts that have incorporated social networking sites into their educational life. The staff and teachers at Blaine High School in Minnesota's Anoka-Hennepin District 11 had been considering the pros and cons of establishing a school Facebook page when the…

Too often, organizations make the mistake of treating malware infections as a series of independent occurrences. Each time a malicious program is discovered, IT simply cleans up or rebuilds the affected host, and then moves on with routine operational tasks. Yet, this approach doesn't allow the institution to keep up with the increasingly…
