802.1X and NAC: Best Practices for Effective Network Access Control

14136_802.1x_WP

802.1X provides an authentication mechanism for devices and users attempting to connect to wired and wireless LANs. Network Access Control (NAC) solutions provide both authentication of users and devices – much like 802.1X – as well as validation of the security posture of devices attempting to connect to a network.

There is often confusion between the functions and benefits of 802.1X vs. NAC solutions. This paper explores the fundamentals of 802.1X and NAC technologies, and explains why a combination of both is often required to provide the level of security, control and visibility needed in today’s networks.

What’s Inside:

  • Overview of 802.1x including benefits and core functionality required to effectively control network access
  • Overview of NAC solutions including benefits and core functionality required to effectively control network access
  • Detailed comparison between the two technologies including similarities and differences, benefits and limitations of each approach in different scenarios
