Cisco Cisco Web Security Appliance S690 User Guide

Router Security

Choose whether or not to require a password for this 
service group. If required, enter the password in the 
password fields. The password can contain up to seven 
characters.

When you enable security for a service group, every 
appliance and WCCP router that uses the service group 
must use the same password.

Requiring a password enables you to control which 
routers and WCCP-enabled systems, such as the Web 
Security appliance, become part of the service group.

WCCP uses the MD5 hash protocol to encrypt the 
password.

Note — Each appliance or WCCP router in the service 
group authenticate the security component in a 
received WCCP packet immediately after validating 
the WCCP message header. Packets failing 
authentication are discarded.
