I am a relative novice in the arena of firewalls but am attempting
to learn as much as I can. Monitoring this forum on basic fw issues to
the most esoteric is exceptionally enlightening. I have been
implementing L/WAN's for about 9 years and consider myself relatively well
qualified in certain areas.
Coming at the issue of firewalls as a small system integration house
we researched what a firewall is and what is important. What is important
as I see it is to keep the unwanted out while inconveniencing those who
need access as little as possible..
First: How is security rated A1, B3, B2, B1, C2, C1 in the US, other
similar grading scales in England/Germany and probably countless others
worldwide. Then to find out what was the best achievable security rating
for a product that is usable.
The most secure, usable, firewall we have found to date is the Cyberguard
As mentioned the products are B1 compliant (awaiting certification)....
They are relatively easy to setup , nice GUI and it has built in the ablity
for most "standard "(excuse the word) proxies and allows creation
of probably anything you might need. It is priced competitively with
Sidewinder, Raptor and the other high-end hardened O/S FW's available but
as far as I know it is the only one that is B compliant.
If you need to purchase a firewall, I do not see how anyone ever
chooses anything other than the Cyberguard.
Thanks for your time.
