This exam includes communication security, infrastructure security, cryptography, access control, authentication, external attack and operational and organization security. For the preparations for this examination I used Security+ Certification Exam Cram 2 Study Kit, and InsideScoop to Security+ Technology Second Edition Exam SY0-101 by Tcat Houser and Helen O'Boyle book with an exam simulation test from ucertify.com. I think it was a good combination. The Exam Cram 2 enhanced my knowledge about the subject and simulation test increased my confidence as well as knowledge.
