QuestionQ11

VerifiedInformation Security Concepts

Firewall protection is delivered by different firewall types. One type functions at the session layer of the OSI model, or the TCP layer of TCP/IP, and monitors TCP handshaking between packets to decide whether a requested session is legitimate. This level conceals information about the private networks it protects, but it does not filter individual packets. Identify the firewall type described.

Explanation

A circuit-level gateway validates TCP sessions by monitoring the connection handshake at the session/TCP level. It obscures the protected private network while avoiding inspection and filtering of individual packets.
