Optimal Power Flow (OPF) is a crucial part of the Energy Management System (EMS) as it determines individual generator outputs that minimize generation cost while satisfying transmission, generation, and system-level operating constraints. OPF relies on a core EMS routine, namely state estimation, which computes system states, principally bus voltages/phase angles at the buses. However, state estimation is vulnerable to false data injection attacks in which an adversary can alter certain measurements to corrupt the estimator's solution without being detected.

ABSTRACT: Attack graphs used in network security analysis are analyzed to determine sequences of exploits that lead to successful acquisition of privileges or data at critical assets.
ABSTRACT: Intrusive multi-step attacks, such as Advanced Persistent Threat (APT) attacks, have plagued many well-protected businesses with significant financial losses. These advanced attacks are sophisticated and stealthy, and can remain undetected for years as individual attack steps may not be suspicious enough. To counter these advanced attacks, a recent trend is to leverage ubiquitous system monitoring for collecting the attack provenance for a long period of time and perform attack investigation for identifying risky system behaviors.
ABSTRACT: A repository of privacy incidents is essential for understanding the attributes of products and policies that lead to privacy incidents. We describe our vision for a novel privacy incidents database and our progress toward building a prototype.
ABSTRACT: Countries vary greatly in the extent to which their computers encounter and host attacks. Empirically identifying factors behind such variation can provide a sound basis for policies to reduce attacks worldwide.
