I would recommend the following URL: csrc.nist.gov/publications/nistpubs/800-41/sp800-41.pdf where you can find a long but very detailed document titled: NIST Firewall Guide and Policy Recommendations
Regards, Francesco -----Messaggio originale----- Da: David Campbell [mailto:[EMAIL PROTECTED]] Inviato: lunedi 1 aprile 2002 22.27 A: [EMAIL PROTECTED] Oggetto: Firewalls What is the difference between the various levels of Firewalls. My current requirement is comparing a (router-based) level 3 firewall to a (PIX) level 7 firewall. Can anyone explain the differences? Does anyone know of a good resource that defines/compares the attributes of firewalls of different levels (perhaps in tabular form)? Thanks, Dave
