CompTIA Security+ 2011: Network Protocols, Attacks, and Defenses

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


Network security professionals must have a firm understanding of the transport mechanisms and attacks faced by traffic entering and exiting a network environment. This course examines the TCP/IP protocol suite, the OSI model, and the different protocols that operate within the layers of these models. This course also examines various attacks that protocols and ports can face, along with the tools that can be used to detect these attacks. This course helps prepares the learner to write the CompTIA Security+ Certification SYO-301.

Target Audience
