Security Paradigm is Changing The burden on StateNet’s members to secure all aspects of the network and business is rapidly growing heavier • Assessing Security Risks • Defining & Authoring Security Policy • Designing & Implementing Security Infrastructure • Enforcement of Security Policy Self Defending Network Initiative (SDNI) will result in the network making intelligent admission and defense decisions while helping to enforce security policy compliance.

Cisco Network Admission Control (NAC) • Cisco Network Admission Control (NAC) is Cisco-led, industry program focused on limiting damage from emerging security threats such as viruses and worms • NAC is a significant step forward in security policy compliance and enforcement • In NAC, customers can allow network access only to compliant and trusted endpoint devices (e.g. PCs, servers, PDAs) and can restrict the access of non-compliant devices • Initial NAC co-sponsors include Network Associates, Symantec, and Trend Micro • NAC is the first phase of the Cisco Self-Defending Network Initiative • These efforts are designed to dramatically improve the ability of networks to identify, prevent, and adapt to threats
Cisco NAC Solution Overview NAC Solution:Leverage the network to intelligently enforce access privileges based on endpoint security posture. The Cisco network helps force corporate security compliance. NAC Characteristics: Ubiquitous solution for all connection methods Validates all endpoints/hosts Endpoint Attempting Network Access Network Access Devices Leverages customer investments in Cisco network and AV solutions Policy Server Decision Points Cisco Secure ACS Policy (AAA) Svr AV Vendor Svr Quarantine & remediation services Credentials Credentials Credentials Deployment scalability RADIUS Access Rights Comply? NAC enforces the security policies as defined on the ACS by the user. It does not author the policies. Notification Cisco Trust Agent Enforcement
