The Enemy Within: Firewalls and Backdoors

Posted by CowboyNeal on from the securing-the-perimeter dept.

hrbrmstr writes "SecurityFocus is running an article on firewalls and backdoors on their InFocus site. They provide info on firewall types, backdoor classifications, some examples of real backdoors and tips on mitigating their use on your network." Some good topics explained for the beginner, and it's a nice refresher for the veteran admin as well.

    Allowing ALL ougoing and RELATED incoming traffic is hardly secure setup. Every fscking worm/backdoor is allowed to call home, replicate itself or even participate in DDOS network. I also doubt that netgear cares about actual packet payload (layers 4-7). I guess that they're using dynamic packet filter.
