Image via WikipediaTCP Split Handshake Issue 
those days I’ve read on the news a lot of noise about an NSS test that were reporting a TCP handshake security hole (TCP Split Handshake Issue) in several commercial firewalls.
The question is interesting from several points of view: 
are IPS and firewall really secure? 
is a vulnerability really a security issue?
how does this vulnerability affect me?
