The Security+ certification is one of the latest certifications developed by CompTIA (who also manage the widely-recognized and highly-respected A+ and Network+ certifications) in response to both corporate and government requests for a certification that validates foundation-level IT security skills. Topics covered include access control, authentication, intrusion detection, malicious code, cryptography, physical security, disaster recovery, policies and procedures, and more. This book provides in-depth coverage of all official exam objectives and includes hundreds of challenging review questions, electronic flashcards, and a searchable electronic version of the entire book.
