Re: Attacking TACACS

[lists () packetfocus com]

Hey Mike,

DoS it :) 

  Cisco devices should have a secondary login stored locally if they can't reach the TACACS server. You can test this 
my flooding the port. UDPFlood so on. This could also test for security setting on the Cisco Gear.

 - TACACS (Terminal Access Controller Access Control System) is an older authentication protocol common to Unix 
networks that allows a remote access server to forward a user's logon password to an authentication server to determine 
whether access can be allowed to a given system. TACACS is an encryption protocol and therefore less secure than the 
later TACACS+ and Remote Authentication Dial-In User Service protocols. A later version of TACACS is XTACACS (Extended 
TACACS). Both are described in Request for Comments 1492.
