Cisco and NSS Labs still arguing firewall vulnerability test results

NSS Labs today is expected to say four out of five vendors -- Palo Alto Networks, Juniper, Fortinet and SonicWall -- whose firewall equipment it said was vulnerable to a hacker exploit have corrected the problem. The fifth, Cisco, maintains its ASA firewall isn't susceptible to the exploit known as the "TCP Split Handshake," which lets an attacker remotely fool the firewall into thinking an IP connection is a trusted one behind the firewall.
