Security Basics: Re: what should I do when....

[Adriel Desautels <adriel () netragard com>]

Ansgar,
	You can not bullet proof a computer system by using a firewall even if 
you block all traffic to and from that system. In most configurations 
firewalls block inbound connection attempts to *internal* systems, while 
they permit outbound attempts from those systems.
	It is my opinion that firewalls are not security devices as much as 
they are traffic shaping devices. Their job is to control network 
connections and the flow of traffic, not to ensure that something can't 
be hacked.
