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. Although not a prerequisite, it is recommended that CompTIA Security+ candidates have at least two years on-the-job networking experience, with an emphasis on security. The CompTIA Network+ certification is also recommended.

Because human error is the number one cause for a network security breach, CompTIA Security+ is recognized by the technology community as a valuable credential that proves competency with information security. Major corporations such as Sun, IBM/Tivoli Software Group, Symantec, Motorola, Hitachi Electronics Services and Verisign value the CompTIA Security+ certification and recommend or require it of their IT employees.
