CompTIA Security+ validates knowledge of communication security, infrastructure security, cryptography, operational security, and general security concepts. It is an international, vendor-neutral certification that is taught at colleges, universities and commercial training centers around the world.
The Security+ exam covers the most important foundational principles for securing a network and managing risk. Access control, identity management and cryptography are important topics on the exam, as well as selection of appropriate mitigation and deterrent techniques to address network attacks and vulnerabilities. Security concerns associated with cloud computing, BYOD and SCADA are addressed in the SY0-401 exam.
