Firewall as a part of sec life

["__ Radien__" <radien@xxxxxxxxx>]

Dear All
(Here My Idea)

  Configuring a firewall is just a chapter of security life of a
system(not just a linux box). 

  And two latest chapter is 

. Optimization (in configuration and/or kernel)
. Testing the security issues(e.g. security assessment tools)
.  keeping updat2date

  So what is your idea about testing a firewall:
1. Configuration to satisfy our needs
2. Keep my things secure
3. Is this firewall, that I'm using, good enough?( in troughput, etc)

Regards
