Subject: Drop Input Policy
Date: Tue, 14 Feb 2006 12:02:10 -0700 [thread overview]
Message-ID: <1139943730.29158.254367263@webmail.messagingengine.com> (raw)
If the default INPUT chain policy is set to drop is there any reason to
explicitly add rules to drop packets within the firewall script? I am
reading various firewall books and it is recommended that you set the
default INPUT chain to drop. After this is done, they go on to construct
a firewall to drop all sorts on packets on the INPUT chain. I am
somewhat confused why these rules are needed when your default is to
drop. Can you simply just add accept rules? Is the default drop policy
a safety net and it is good practice to explicitly drop packets within
your script?
Thanks
