Chapter 8 Configuring AAA Rules for Network Access

Configuring Authorization for Network Access

Step 8 In the Service field, enter an IP service name or number for the destination service, or click the ellipsis (...) to choose a service.

Step 9 (Optional) In the Description field, enter a description.

Step 10 (Optional) Click More Options to do any of the following:

•To specify a source service for TCP or UDP, enter a TCP or UDP service in the Source Service field.

•The destination service and source service must be the same. Copy and paste the Destination Service field content into the Source Service field.

•To make the rule inactive, clear the Enable Rule check box. You may not want to remove a rule, but instead turn it off.

•To set a time range for the rule, in the Time Range drop-down list, choose an existing time range. To add a new time range, click the ellipsis (...). For more information, see the “Configuring Time Ranges” section on page 20-15in the general operations configuration guide.

Step 11 Click OK.

The Add Authorization Rule dialog box closes, and the rule appears in the AAA Rules table.

Step 12 Click Apply.

The changes are saved to the running configuration.

Configuring RADIUS Authorization

When authentication succeeds, the RADIUS protocol returns user authorizations in the access-accept message sent by a RADIUS server. For more information about configuring authentication, see the “Configuring Network Access Authentication” section on page 8-6.

When you configure the ASA to authenticate users for network access, you are also implicitly enabling RADIUS authorizations; therefore, this section contains no information about configuring RADIUS authorization on the ASA. It does provide information about how the ASA handles ACL information received from RADIUS servers.

You can configure a RADIUS server to download an ACL to the ASA or an ACL name at the time of authentication. The user is authorized to do only what is permitted in the user-specific ACL.

Note If you have enabled the Per User Override Setting (see the Configuration > Firewall > Access Rules > Advanced > Access Rules Advanced Options dialog box), be aware of the following effects of the per-user-override featureon authorization by user-specific ACLs:

•Without the per-user-override feature, traffic for a user session must be permitted by both the interface ACL and the user-specific ACL.

•With the per-user-override feature, the user-specific ACL determines what is permitted.

This section includes the following topics:

•Configuring a RADIUS Server to Send Downloadable Access Control Lists, page 8-14

•Configuring a RADIUS Server to Download Per-User Access Control List Names, page 8-17
