How to manage large access-lists on FWSM

Team I have a rather large access-list in one of my firewalls and was wondering if anyone has any rules of thumbs to go by when building a complex access lists. I currently use object groups but what is a good rule for acls with servers, users and diffent needs for access?

We use object-groups as well. We typically create an object for source servers (if more than 1), the ports (if more than 1 or 2) and another group for destination server(s). We have a very restrictive security policy so each rule must be specific. I think it makes it hard to see what the ACL's really do, but it shortens the config.

Hope that helps.

We try to do something very similar but over time alot of 1 offs have creeped into the acls.

Thanks for the reply
