Secured Branch Router Configuration Example
Configure
!---Restrict user access to the network:
!---(a) Run authorization to determine if the user is allowed to run an EXEC shell.
!---(b) Enable authorization that applies specific security policies on a per-user basis.
!---You must use the "aaa authorization auth-proxy" command together with the
!---"ip auth-proxy <name>" command (later in this configuration). Together, these
!---commands set up the authorization policy to be retrieved by the firewall.
aaa authorization exec default group SJ none
aaa authorization auth-proxy default group SJ
!---Make sure that the same session ID is used for each AAA accounting service type
!---within a call.
aaa session-id common
.
.
.
!---Define a set of inspection rules. In this example, the set is called "myfw."
!---Include each protocol that you want the Cisco IOS firewall to inspect.
ip inspect name myfw cuseeme timeout 3600
ip inspect name myfw ftp timeout 3600
ip inspect name myfw http urlfilter timeout 3600
ip inspect name myfw rcmd timeout 3600
ip inspect name myfw realaudio timeout 3600
ip inspect name myfw smtp timeout 3600
ip inspect name myfw sqlnet timeout 3600
ip inspect name myfw streamworks timeout 3600
ip inspect name myfw tftp timeout 30
ip inspect name myfw udp timeout 15
ip inspect name myfw tcp timeout 3600
ip inspect name myfw vdolive
!
!---(Optional) Set the length of time an authentication cache entry, along with its
!---associated dynamic user access control list, is managed after a period of inactivity.
ip auth-proxy inactivity-timer 120
!---Create an authentication proxy rule; in this example it is named "aprule."
!---Set HTTP to trigger the authentication proxy.
ip auth-proxy name aprule http
!
!---Configure the Cisco IOS Intrusion Protection System (IPS) feature:
!---Specify the location from which the router loads the Signature Definition File (SDF).
!---(Optional) Specify the maximum number of event notifications that are placed
!---in the router's event queue.
!---Disable the audit of any signatures that your deployment scenario deems unnecessary.
!---Name the IPS rule, so that you can apply the rule to an interface.
!---Later in this example, this rule (named "ids-policy") is applied to FE 0/0.
ip ips sdf location tftp://192.168.1.3/attack-drop.sdf
ip ips po max-events 100
ip ips signature 1107 0 disable
ip ips signature 3301 0 disable
ip ips name ids-policy
!
!---Configure the Firewall Websense URL Filtering feature:
!---(Optional) Set the maximum number of destination IP addresses that can be cached
!---into the cache table, which consists of the most recently requested IP addresses
!---and respective authorization status for each IP address.
!---Specify domains for which the firewall should permit or deny all traffic
!---without sending lookup requests to the Firewall Websense URL filtering server (UFS).
!---Specify the IP address of the Firewall Websense UFS.
ip urlfilter cache 0
ip urlfilter exclusive-domain permit www.cisco.com
ip urlfilter server vendor websense 192.168.1.116
