In this manner, no ACLs exist for any port, except for the Telnet ACL. Until such time, the firewall is configured to disallow all traffic except Telnet.

After authentication, a remote host can then execute a Telnet session and open the corporate site firewall. In a typical environment, Lock and Key security puts in place an access control list (ACL) that filters all traffic until the remote user has authenticated with the security mechanism. The NAS is the authentication mechanism and is responsible for altering the access list for the incoming interface to enable the privileges allowed to that user. Lock and Key security is activated after the user has been authenticated by the network's CiscoSecure ACS. Provided that the user is in an access list, this command uses a configuration template to open a hole in the firewall.ДЇigureВ D-1: Lock and Key with CiscoSecure ACS When a user tries to log in, the CiscoSecure ACS runs the access-enable command. In essence, you can allow user access through a firewall dynamically, without compromising security restrictions. Lock and Key security defines dynamic access lists that grant access per user, on a specific source/destination host basis through a user authentication process.

Ip local pool default 171.68.187.1 171.68.187.48Д¬onfiguring Your CiscoSecure ACS and Cisco NAS for Lock and KeyДЄn improved security solution starting with Cisco IOS Release 11.1 software is the Lock and Key Security feature (see Figure D-1). You can enter the following sample configuration directly into your NAS to immediately enable the CiscoSecure ACS for RADIUS-based security services.ДЄaa authentication login secure radius localДЄaa authentication ppp secure if-needed radius local The result is uniform authentication, authorization, and accounting services, which in turn provides centralized user management as well as accounting records necessary for billing. In this sample configuration, the Cisco AS5200 can use the same authentication and accounting servers as other vendors' equipment. The sample configuration that follows might be a typical configuration for an IS P with an existing RADIUS installation. Remote node IP dialup Configuring Your CiscoSecure ACS and Cisco NAS for RADIUSД«ecause the CiscoSecure ACS supports the RADIUS protocol, you can configure your network access server for RADIUS and achieve the same, or equivalent, security services as with the TACACS+ protocol.Use the information here to help you configure your CiscoSecure ACS and Cisco network access server (NAS) for: This appendix provides examples you can apply directly to your own CiscoSecure access control server (ACS).
