Certified Cloud Security Professional (CCSP) — Question 346

Firewalls are used to provide network security throughout an enterprise and to control what information can be accessed--and to a certain extent, through what means.
Which of the following is NOT something that firewalls are concerned with?

Answer options

• A. IP address
• B. Encryption
• C. Port
• D. Protocol

Correct answer: B

Explanation

The correct answer is B, as firewalls primarily operate at the network and transport layers, focusing on IP addresses, ports, and protocols to control traffic. Encryption, while important for securing data, is not a primary concern for firewalls, which do not typically analyze the contents of encrypted packets.
