A guide to endpoint compliance enforcement
Today, a variety of security challenges affect all businesses
regardless of size and location. Companies face ongoing challenges with the
fight against malware such as worms, viruses, and spyware. Today's mobile
workforce attach numerous devices to the corporate network that are harder to
control from a security policy perspective. These host devices are often lacking
antivirus updates and operating system patches, thus exposing the entire network
to infection. As a result, worms and viruses continue to disrupt business, causing
downtime and continual patching. Noncompliant servers and desktops are far too
common and are difficult to detect and contain. Locating and isolating infected
computers is time consuming and resource intensive.
Network Admission Control (NAC) uses the network infrastructure
to enforce security policy compliance on all devices seeking to access network
computing resources, thereby limiting damage from emerging security threats.
NAC allows network access only to compliant and trusted endpoint devices (PCs,
servers, and PDAs, for example) and can restrict the access of and even remediate
noncompliant devices.
Cisco Network Admission Control, Volume I, describes
the NAC architecture and provides an in-depth technical description for each
of the solution components. This book also provides design guidelines for enforcing
network admission policies and describes how to handle NAC agentless hosts.
As a technical primer, this book introduces you to the NAC Framework solution
components and addresses the architecture behind NAC and the protocols that
it follows so you can gain a complete understanding of its operation. Sample
worksheets help you gather and organize requirements for designing a NAC solution.
- Understand how the various NAC components work together to defend your network
- Learn how NAC operates and identifies the types of information the NAC solution
uses to make its admission decisions
- Examine how Cisco Trust Agent and NAC-enabled applications interoperate
- Evaluate the process by which a policy server determines and enforces a
policy
- Understand how NAC works when implemented using NAC-L2-802.1X, NAC-L3-IP,
and NAC-L2-IP
- Prepare, plan, design, implement, operate, and optimize a network admission
control solution
