I have to write firewall rulesets for a pair of back to back dual vendor firewalls with multiple DMZ's from each. Can anyone recommend a good procedure to use. Opensource would be great but you cant really beat a good book.
Standard rules: Default everything to closed and see what breaks, open ports as required. "Building Internet Firewalls" (O'Reilly and Associates) is a good book to start with.
Also can anyone recommend a good resource for translating services into ports etc
