Interdisciplinary Cybersecurity for Resilient Cyberdefense

Cybersecurity's role is to protect confidentiality, integrity, and availability of enterprise assets. Confidentiality secures data from theft, integrity mitigates modification of data in a malicious way, and availability assures continuation of systems' access and services. However, achieving these goals is difficult due to the mushrooming of various cyber attackers that come from individuals or state actors with motives ranging from ideological, financial, state-sponsored espionage, revenge, or simple curiosity and boredom. The difficulty also lies in the complexity of the cyber layers that are not well studied. Layers that interconnect and require effective communication and collaboration. This effectiveness is still lacking in cyber programs. To understand this complexity, one must seek an interdisciplinary approach to cybersecurity. Interdisciplinary study requires understanding of technology, mathematics, engineering, psychology, economics, human factors, and political science. Hence, this dissertation is proposing an Interdisciplinary Cybersecurity for Resilient Cyberdefense or ICRC model that includes (1) building behavioral aspects of cybersecurity with insider threat insights, (2) mastering encryption standards and requirements through developing a novel encryption method, (3) understanding different cyberdefense strategies' costs and payoffs by using game theory, (4) assessing vulnerabilities in the networks and plan ethical hacking in an audit, (5) studying machine learning challenges in cybersecurity to improve tools and set new ontologies for different threats, including the insider threat risk, and (6) address trustworthiness by aligning overall requirements of cybersecurity. ICRC is more than the sum of the above parts; it is a new approach for cybersecurity professionals to consider expanding their expertise to be interdisciplinary. Since cybersecurity is a complex task it requires a team that can handle its complexity. However, a given team's structure, team's hierarchy, and team members' characteristics could affect negatively that team's performance. With executing ICRC, both the team and the individuals seek interdisciplinary approaches to contribute to enterprise's resilience.
