Formal evaluation just means that the features judged relevant to the evaluation can be minimally verified. On the flip side, there's David Litchfield's observation in the introduction to The Oracle Hacker's Handbook: "The Oracle RDBMS was evaluated under Common Criteria to EAL4... However, the first few versions of Oracle that gained EAL4 had a buffer overflow in the authentication mechanism." He goes on to that standards are necessary to some extent but not fully indicative. You'll find summary arguments and starting links off the Common Criteria's Wikipedia entry. Given such limitations, perhaps you might propose a more open evaluation and make code access for audit, including by escrow access for an established third-party authority, as a major criteria?

I've used OpenBSD & PF for a number of years without issue and am now in the position that I want to create a dmz between the Internet and my organisations WAN. Our security people are asking if the firewall that we use is accreditated by ITSEC and I am pretty sure it isn't but it turns out that our security people will be happy is the firewall is accredited for use by another government !

I am very happy with my PF firewalls and their reliability and don't want to be forced into purchasing some cisco / forenet comercial firewall that I've never used before so am desperate to find some details of any foreign governments that are using OpenBSD / PF as a firewall or any details of any certification of the PF firewall.

Can anyone help me out ?

Thanks
Keith
