Several trends in computer security have become prominent since the beginning of the new century and are represented in the program. They include the proliferation of intrusions that exploit new vulnerabilities, the necessity to respond to an increasing number of computer security incidents, the emergence of new security threats and the need to adapt existing approaches and models to handle these threats. Reflecting these trends, the conference includes sessions on attacks and defenses, security of resource-constrained devices, trust and quality of security management, and advanced security models.
