To enable network access authentication, perform the following steps:
Using the access-list command, create an ACL that identifies the source addresses and destination addresses of traffic you want to authenticate.
The permit ACEs mark matching traffic for authentication, while deny entries exclude matching traffic from authentication. Be sure to include the destination ports for either HTTP, Telnet, or FTP in the ACL because the user must authenticate with one of these services before other services are allowed through the security appliance.
To configure authentication, enter the following command:
hostname/contexta(config)# aaa authentication match acl_name interface_name server_group_or_LOCAL
where acl_name is the name of the ACL you created in Step 1, interface_name is the name of the interface as specified with the nameif command.
- - - - - - - - - - - - - - - - - - - - - - -
(Optional) If you are using the local database for network access authentication and you want to limit the number of consecutive failed login attempts that the security appliance allows any given user account, use the aaa local authentication attempts max-fail command.
hostname/contexta(config)# aaa local authentication attempts max-fail 7
