I know that VSE is only the antivirus program. But I'm confused as to what the firewall is. We would need a firewall to compliment VSE, but have no clue what it is. Firewall, HIPS, etc, we're not sure.
Antivirus (Av) detect virus based on pre-defined signature & it does not protect from vulnerability of the system but Hips does not work only on signature based but it also work on system behaviour based & Protocol.
