Cisco Threat Response IDS Requirements

CTR works in conjunction with intrusion detection systems. Your network should have an installation of either or both of the following IDSs:

■ Cisco Intrusion Detection System version 3.x or higher

■ Internet Security Systems RealSecure—CTR has been tested with RealSecure versions 6.5 and 7.0

You can access the CTR GUI from any computer in your environment; CTR uses an SSL connection under Microsoft Internet Explorer. For example, to access the CTR server with an IP address of 192.168.100.100, simply type this URL in your Explorer address box:

https://192.168.100.100 HTTPS specifies that your application should use SSL.

With the need for greater security between devices and switches, the IEEE committee came up with a new technology, 802.1X authentication.
