  • Balancing Ex Ante Security with Ex Post Mitigation
    Is an Ounce of Prevention Worth a Pound of Cure? Balancing Ex Ante Security with Ex Post Mitigation Veronica Marotta ), Heinz College, Carnegie Mellon University Sasha Romanosky ) RAND Corporation Richard Sharp ), Starbucks Alessandro Acquisti ( ), Heinz College, Carnegie Mellon University Abstract Information security controls can help reduce the probability of a breach, but cannot guarantee that one will not occur. In order to reduce the costs of data breaches, firms are faced with competing alternatives. Investments in ex ante security measures can help prevent a breach, but this is costly and may be inefficient; ex post mitigation efforts can help reduce losses following a breach, but would not prevent it from occurring in the first place. We apply the economic analysis of tort and accident law to develop a two-period model that analyzes the interaction between a firm and its consumers. The firm strategically chooses the optimal amount of ex ante security investments and ex post mitigation investments in the case of a breach; consumers, that can engage in ex post mitigation activities. We show that it can be optimal for a firm to invest more in ex post mitigation than in ex ante security protection. However, there also exist situations under which a firm finds it optimal to not invest in ex post mitigation, and simply invest a positive amount ex ante. In addition, we find that a social planner seeking to minimize the social cost from a breach should not incentivize the firm to bear all consumers loss: as long as consumers have feasible tools for mitigating the downstream impact of data breaches, they should be responsible for a fraction of the expected loss caused by the breach.

Suzanne Barber cates. UTCID Report #18-06 MAY 2018 Sponsored By Identity Threat Assessment and Prediction Identity theft and related threats are increasingly common occurrences in today’s world. Developing tools to help understand and counter these threats is vitally important. This paper discusses some noteworthy results obtained by our Identity Threat Assessment and Prediction (ITAP) project. We use news stories to gather raw data about incidents of identity theft, fraud, abuse, and exposure. Through these news stories, we seek to determine the methods and resources actually used to carry out these crimes; the vulnerabilities that were exploited; as well as the consequences of these incidents for the individual victims, for the organizations affected, and for the perpetrators themselves. The ITAP Model is a large and continually growing, structured repository of such information. There are currently more than 5,000 incidents captured in the model.

  • A Framework for Technology-Assisted Sensitivity Review: Using Sensitivity Classification to Prioritise Documents for Review
    A Framework for Technology-Assisted Sensitivity Review: Using Sensitivity Classification to Prioritise Documents for Review Graham McDonald Submitted in fulfilment of the requirements for the Degree of Doctor of Philosophy School of Computing Science College of Science and Engineering University of Glasgow March 2019 Abstract More than a hundred countries implement freedom of information laws. In the UK, the Freedom of Information Act 2000 (c. 36) (FOIA) states that the government’s documents must be made freely available, or opened, to the public. Moreover, all central UK government departments’ documents that have a historic value, for example the minutes from significant meetings, must be transferred to the The National Archives (TNA) within twenty years of the document’s cre- ation. However, government documents can contain sensitive information, such as personal in- formation or information that would likely damage the international relations of the UK if it was opened to the public. Therefore, all government documents that are to be publicly archived must be sensitivity reviewed to identify and redact the sensitive information, or close the document un- til the information is no longer sensitive. Historically, government documents have been stored in a structured file-plan that can reliably inform a sensitivity reviewer about the subject-matter and the likely sensitivities in the documents. However, the lack of structure in digital document collections and the volume of digital documents that are to be sensitivity reviewed mean that the traditional manual sensitivity review process is not practical for digital sensitivity review. In this thesis, we argue that the automatic classification of documents that contain sensitive information, sensitivity classification, can be deployed to assist government departments and human reviewers to sensitivity review born-digital government documents.

  • The Protection of Classified Information: the Legal Framework
    The Protection of Classified Information: The Legal Framework Jennifer K. Elsea Legislative Attorney January 10, 2011 Congressional Research Service 7-5700 www.crs.gov RS21900 CRS Report for Congress Prepared for Members and Committees of Congress The Protection of Classified Information: The Legal Framework Summary The publication of secret information by WikiLeaks and multiple media outlets has heightened interest in the legal framework that governs security classification, access to classified information, agency procedures for preventing and responding to unauthorized disclosures, and penalties for improper disclosure. Classification authority generally rests with the executive branch, although Congress has enacted legislation regarding the protection of certain sensitive information. While the Supreme Court has stated that the President has inherent constitutional authority to control access to sensitive information relating to the national defense or to foreign affairs, no court has found that Congress is without authority to legislate in this area. This report provides an overview of the relationship between executive and legislative authority over national security information, and summarizes the current laws that form the legal framework protecting classified information, including current executive orders and some agency regulations pertaining to the handling of unauthorized disclosures of classified information by government officers and employees. The report also summarizes criminal laws that pertain specifically to the unauthorized
