CIS 455 Network Security

Network security focuses on the prevention and monitoring of unauthorized access, misuse, modification, or denial of a computer network and network-accessed resources.

Topics include Internet security techniques and protocols, authentication, email security, encryption, web security, network management, firewalls, network security policies, and tools and techniques used by malicious network attackers.
