Why is it so challenging to block packets from Remote Access Troans that use port 80 for network communications? Choose three.
The correct answer is A. To a firewall, the traffic appears simply to be from an internal user making an innoccous HTTP B. Port 80 outbound is normally open on corporate firewalls D. Not all firewalls are capable of inspecing data in the HTTP data fields for evidence of tunneling. See the full explanation below for the reasoning.
