Description

The combination of national events and persistent intrusion into well-known network sites has made network security a very hot topic. This class provides a mix of theory and practical application that will help you understand this very complex subject.

First, the basic concepts and terminology related to keys and encryption will be studied. Then the major standards and implementations of those standards will be investigated. While the theory behind much of cryptography involves a substantial amount of mathematics, this course will develop explanations of these concepts without requiring formal mathematics training. Topics covered will include public and private keys, authentication, certificates, security policies, and VPNs. Protocols covered include DES, 3DES, Kerberos, IPSec, L2TP, PPTP, Diffie-Helman, RSA and others. Two or more case studies are used. Exercises also reinforce the concepts discussed. This course aggressively covers the material an prepares students for further study of network security.

Who can benefit from this class?

Any technician, analyst, manager, engineer, or personnel providing network support.

Prerequisites to Course

Individuals should have a general knowledge of LANs, WANs, and network technology including IP protocol.
