Permissive Firewall Policy

[Kevin Hinze <kevin.hinze () navigators org>]

New to the list, so hope this has not already been covered numerous times.

I have been asked to move from a restrictive policy of only
allowed/permitted ports are allowed through the Firewall to a permissive
policy of deny known ³bad² port/protocols and allow all else.  Does anyone
have lists, bookmarks or the like to show a list of known ³bad² ports?  I
believe this is a bad idea but need some information to prove how difficult
it will be to manage.

Thanks in advance,

Kevin Hinze
