QTNA: Firewall Types

In CyberVista’s Questions That Need Answers (QTNA) video series, we tackle some of the most testable and important cybersecurity questions on a weekly basis. This week we’re covering a question related to types of firewalls. Here we go…

An attacker is using HTTP tunneling to evade a firewall. However, their traffic is being blocked as it traverses the port. The attacker notices other HTTP traffic is being allowed through. What is happening?

• Port 80 monitored by stateless firewall
• Port 443 monitored by application firewall
• Port 80 monitored by stateful firewall
• Port 80 monitored by proxy firewall
