Ch11 Basic Cryptography
Security+ Guide to Network Security Fundamentals, 3rd Edition, by Mark Ciampa Knowledge and skills required for Network Administrators and Information Technology professionals to be aware of security vulnerabilities, to implement security measures, to analyze an existing network environment in consideration of known security threats or risks, to defend against attacks or viruses, and to ensure data privacy and integrity. Terminology and procedures for implementation and configuration of security, including access control, authorization, encryption, packet filters, firewalls, and Virtual Private Networks (VPNs). CNIT 120: Network Security http://samsclass.info/120/120_S09.shtml#lecture Policy: http://samsclass.info/policy_use.htm Many thanks to Sam Bowne for allowing to publish these presentations.
