Cognitive enhancements to support dependability

The threat of cyber-attacks is not limited to the boundary of information systems any longer. Safety and reliability of almost any system can be compromised by exploiting the vulnerabilities in the information systems that connect with or control them. Agile and ongoing manipulation of (redundant and diverse) system components, defense mechanisms and system resources is essential for surviving attacks and continuing operation. Cyber-defense administration-- dynamic management of components, defense mechanism and systems resources--is therefore a current topic of significant interest to the dependability community. In this paper, we present our ongoing work on automated support for intelligent cyber-defense administration.
