Cisco Nac Appliance: Enforcing Host Security with Clean Access

Angebote / Angebote:

Cisco NAC Appliance from Cisco Press presents an overview of real world Cisco NAC Appliance (formerly known as Clean Access) deployment scenarios. The book provides best practices for communicating to the user community before deploying the NAC Appliance and how best to plan/design for the eventual merger of NAC framework and NAC Appliance solutions. The majority of viruses and worms in existence today would be successfully stopped using an up to date operating system along with an up to date anti-virus client. The concept of checking how up to date a host's operating system, antivirus client, and spyware removal tools are before they are given access to the network is relatively new. It is not so much the operating system's or anti-virus client's lack of ability to stop the majority of attacks so much as it is a company's lack of ability to enforce, at the network layer, security policies that require endpoint systems to have updated patches and AV software installed. This ability is the essence of what the Cisco NAC Appliance provides. This book is the ultimate reference to the Cisco NAC Appliance, and is an essential book in the library of any networking professional that works on host security or security policy enforcement.
