CompTIA Security+ 2011: Cryptography and Public Key Infrastructures

This course is included in our On-demand training solution.


Guaranteeing end-to-end security in communication, document, and database infrastructures is incredibly important in internetworking environments. This course examines cryptography and the different algorithms, ciphers and tools that can be used to secure information, and to protect against attacks. Symmetric and asymmetric algorithms are examined, along with block and stream ciphers, one-time pads, and steganography. This course also examines message authentication, digital signatures, Public Key Infrastructures and certification authorization and revocation. This course helps prepares the learner to write the CompTIA Security+ Certification SYO-301.

Target Audience

Individuals who have day to day technical information security experience who are looking to validate that knowledge. It is recommended that individuals have a minimum of 2 years experience in IT administration with a focus on security and a broad knowledge of security concerns and implementations.


Expected Duration
