Reduction Of False Positives In Intrusion Detection Based On Extreme Learning Machine With Situation Awareness, Donald A. Burgio

CCE Theses and Dissertations

Protecting computer networks from intrusions is more important than ever for our privacy, economy, and national security. Seemingly a month does not pass without news of a major data breach involving sensitive personal identity, financial, medical, trade secret, or national security data. Democratic processes can now be potentially compromised through breaches of electronic voting systems. As ever more devices, including medical machines, automobiles, and control systems for critical infrastructure are increasingly networked, human life is also more at risk from cyber-attacks. Research into Intrusion Detection Systems (IDSs) began several decades ago and IDSs are still a mainstay of computer and …

Examining The Impact Of Learning Management Systems In Computer Programming Courses, Mohammed Naif Alatawi

CCE Theses and Dissertations

The development of software and communication technologies in education has led the majority of universities worldwide to integrate the functions of Learning Management Systems (LMSs) into their learning environments. LMSs offers several features that encourage their use by universities and other educational institutions, such as unlimited access to course content, easy tracking of learners’ progress and performance, and reduced costs in terms of both money and time. Most existing LMS studies have been focused on experienced LMS users who are familiar with its functions, with little consideration given to new users. Furthermore, although previous researchers have identified various means of …

The Factors That Impact Patient Portal Utilization, William Carroll Reed

CCE Theses and Dissertations

Spawned by legislative mandates, such as the American Recovery and Reinvestment Act of 2009’s Health Information Technology for Economic and Clinical Health Act, and individuals desiring to have more personal accountability for their health and healthcare, the introduction and use of electronic personal health information (ePHI) has grown substantially. Given that most ePHI is maintained within the healthcare delivery system, an information portal is required for individuals to have access to the ePHI. As a result, the legislation required the introduction and use of patient portals to grant such access.

Despite substantial financial incentives and disincentives for healthcare organizations to …

An Examination Of User Detection Of Business Email Compromise Amongst Corporate Professionals, Shahar Sean Aviv

CCE Theses and Dissertations

With the evolution in technology and increase in utilization of the public Internet, Internet-based mobile applications, and social media, security risks for organizations have greatly increased. While corporations leverage social media as an effective tool for customer advertisements, the abundance of information available via public channels along with the growth in Internet connections to corporate networks including mobile applications, have made cyberattacks attractive for cybercriminals. Cybercrime against organizations is a daily threat and targeting companies of all sizes. Cyberattacks are continually evolving and becoming more complex that make it difficult to protect against with traditional security methods. Cybercriminals utilize email …

Information Systems Security Leadership: An Empirical Study Of Behavioral Influences Of Leaders On Employees’ Security Compliance, Marcus Alan Winkfield

CCE Theses and Dissertations

This empirical study examined the behavioral influences of leaders on employees’ security compliance. Organizations can use leadership concepts in the field of Information Systems (IS) security. Despite the adoption of technical and managerial approaches, organizations still face issues motivating employee IS security compliance. This dissertation argued that organizations need strong leadership to encourage employees. Using the expectancy theory, this paper created a theoretical model to help understand the influence of task and relationship-oriented leadership behaviors on nontechnical controls IS security compliance. The conceptual underpinnings translated into perceived security effort, perceived security performance, and expected security outcomes. The theoretical model was …

Exploring Strategies To Integrate Disparate Bioinformatics Datasets, Charbel Bader Fakhry

Walden Dissertations and Doctoral Studies

Distinct bioinformatics datasets make it challenging for bioinformatics specialists to locate the required datasets and unify their format for result extraction. The purpose of this single case study was to explore strategies to integrate distinct bioinformatics datasets. The technology acceptance model was used as the conceptual framework to understand the perceived usefulness and ease of use of integrating bioinformatics datasets. The population of this study included bioinformatics specialists of a research institution in Lebanon that has strategies to integrate distinct bioinformatics datasets. The data collection process included interviews with 6 bioinformatics specialists and reviewing 27 organizational documents relating to integrating …

Knowledge Sharing And Customer Relations In Mobility, Katie Dyretha Moore

Walden Dissertations and Doctoral Studies

After the events of September 11, 2001, inadequacies in how government organizations and agencies shared knowledge and communication with defense mission partners became readily apparent. A reasonable U.S. government information technology expectation is the integrated use of mobile phones across organizations and agencies. Yet, it is difficult to meet this expectation, as the provisioning process for mobile devices can be different for each government organization or agency. The Department of Commerce National Institute of Standards and Technology does not set provisioning standards, and organizations and agencies determine policies tailored to their particular needs. Using Schein's theory on organizational culture, the …
