Your source for federal standard information security training

CNSS LogoWe are undergoing major improvements!

We still offer low cost, self paced, DOD-certified cyber security training.

Our improved program requires only one low-cost test per chapter, plus a midterm and final.

Elementary Information Security provides thorough and readable information security training. It is designed for students who have completed an introductory computing and programming course. The U.S. National Security Agency has determined that Elementary Information Security conforms fully to the federal training requirements for Information Security (INFOSEC) professionals (NSTISSI 4011). It also covers the core learning outcomes for information assurance and security from the latest IT curriculum recommendations published by the Association for Computing Machinery (ACM) and the Institute for Electrical and Electronics Engineers (IEEE) - the premier professional societies in the field.
