Access Control In And For The Real World, Sara Sinclair

Dartmouth College Ph.D Dissertations

Access control is a core component of any information-security strategy. Researchers have spent tremendous energy over the past forty years defining abstract access-control models and proving various properties about them. However, surprisingly little attention has been paid to how well these models work in real socio-technical systems (i.e., real human organizations). This dissertation describes the results of two qualitative studies (involving 52 participants from four companies, drawn from the financial, software, and healthcare sectors) and observes that the current practice of access control is dysfunctional at best. It diagnoses the broken assumptions that are at the heart of this dysfunction, …

Metamorphic Detection Using Singular Value Decomposition, Ranjith Kumar Jidigam

Master's Projects

Metamorphic malware changes its internal structure with each infection, while maintaining its original functionality. Such malware can be difficult to detect using static techniques, since there may be no common signature across infections. In this research we apply a score based on Singular Value Decomposition (SVD) to the problem of metamorphic detection. SVD is a linear algebraic technique which is applicable to a wide range of problems, including facial recognition. Previous research has shown that a similar facial recognition technique yields good results when applied to metamorphic malware detection. We present experimental results and we analyze the effectiveness and efficiency …

Anonymous: Polemics And Non-Identity, Samuel Chiang

Electronic Thesis and Dissertation Repository

The hacktivist collective Anonymous has been known to follow nonhierarchical, amorphous and sometimes contradictory strategies for online activism. This may weaken their potential to become a populist movement, as out-group members may find Anonymous’s politics obscure and out of reach. Anonymous’s communiqués compensate for this by enabling direct communication with the public. But as a critical discourse analysis finds, the communicative strategies employed deviate from logics of difference and non-identity. They express rigid beliefs, even at times under the banner of universal truth.

However, these findings do not suggest Anonymous inevitably embraces identity. By adopting a Deleuzian concept of minor …

Time Orientation, Rational Choice And Deterrence: An Information Systems Perspective, Michael Brian Pope

Theses and Dissertations

The present study examines General Deterrence Theory (GDT) and its "parent," Rational Choice Theory (RCT), in an information security setting, assessing the behavioral intent to violate organizational policy under varying levels of certainty, severity and celerity of negative sanction. Also assessed is the individual computer user's time orientation, as measured by the Consideration of Future Consequences (CFC) instrument (Strathman et. al, 1994). How does rational consideration of violation rewards influence the impact of sanctions on individuals? How does time orientation impact intent to violate security policy? How do these operate in an IS context? These questions are examined by assessing …

Minimal Trusted Computing Base For Critical Infrastructure Protection, Arun Velagapalli

Theses and Dissertations

Critical infrastructures like oil & gas, power grids, water treatment facilities, domain name system (DNS) etc., are attractive targets for attackers — both due to the potential impact of attacks on such systems, and due to the enormous attack surface exposed by such systems. Unwarranted functionality in the form of accidental bugs or maliciously inserted hidden functionality in any component of a system could potentially be exploited by attackers to launch attacks on the system. As it is far from practical to root out undesired functionality in every component of a complex system, it is essential to develop security measures …
