Firewalls – Performance V Security
While stateful packet filters are the most popular firewall products, their popularity has more to do with their performance than their absolute security.
If security is important to your customers, evidence below suggests advocating application-level gateway firewalls.
When advocating application-level firewalls you should be considering
AXENT Technologies Raptor Firewall 6.5.
‘Trade-off for performance gains against total security’
An attack is described by IT World News (7 July) as being capable of passing through Checkpoint’s FireWall-1 to a supposedly protected port. Rumours that Cisco PIX was also vulnerable to such an attack turned out to be true. Cisco posted a fix for the PASV problem back in March 16 2000.
Application-level gateways are much harder to fool, as the way they maintain state is to have one running process per connection -- and this process can be much more thorough in testing for the correctness of data sent through the firewall.
