This book constitutes the refereed proceedings of the Second International Symposium on Cyber Security, CSS 2015, held in Coeur d'Alene, ID, USA, in April 2015. The 9 revised full papers presented were carefully reviewed and selected from 20 papers. The papers reflect four areas of scholarly work: permissions and trust evaluation, implementation and management; cloud and device security and privacy; social implications of networked and mobile applications; system and process assessments for improved cybersecurity.

This book constitutes the proceedings of the 8th International Conference on Higher Order Logic Theorem Proving and Its Applications, held in Aspen Grove, Utah, USA in September 1995.
The 26 papers selected by the program committee for inclusion in this volume document the advances in the field achieved since the predecessor conference. The papers presented fall into three general categories: representation of formalisms in higher order logic; applications of mechanized higher order logic; and enhancements to the HOL and other theorem proving systems.
