You can issue "show ip access-lists" to show the current access-lists configured on your router.

Also "show running-config" displays the current loaded config in RAM.

"show running-config | begin access-list" will take you to the portion of the config where your access list entries begin.

You should configure AAA and TACACS+ on you routers, this way you can see when certain commands were issued such "enable secret <new password>" etc. from you accounting logs   

TACACS+ gives you centralised control of username and passwords for your routers / switches, as well as other stuff. 

You can have the tac_plus binary running on a locked down server, or two servers for redundancy  

This would make it difficult for someone to change username and passwords, if AAA is configured correctly, they would first have to stop your router talking tacacs to your tacacs server, then try and gues the local username and password.

tac_plus is a freeware tacacs server available on cisco.com

Hope this helps.

Hello full-disclosure,

  I've got a little problem with a cisco router.
  It has obviously been compromised. How do i know, well the password
  has changed. So I want to retrieve the ACL from the RAM (not NVRAM)
  to see what else maybe got compromised.
  Does anyone know how this could be done?

  thanks for any suggestions in advance...
