Which of the following is NOT a function of a firewall?

• A. Block unauthorized traffic from entering the network.
• B. Prevent accidental disclosure of information.
• C. Hide vulnerable systems from the Internet.
• D. Log traffic to and from internal servers.

Answer: (B)

The function of a firewall primarily revolves around controlling traffic between different networks, particularly in protecting private networks from unauthorized access. When considering the functions listed, blocking unauthorized traffic, hiding vulnerable systems from the Internet, and logging traffic to and from internal servers are all established roles that a firewall plays. Blocking unauthorized traffic is one of the core functions of a firewall, which monitors incoming and outgoing traffic and establishes policies on what type of traffic is permissible. Additionally, by hiding vulnerable systems from the Internet, firewalls provide a layer of security that helps prevent direct access to these systems, reducing their exposure to potential attacks. Logging traffic is another essential task of a firewall. It enables administrators to review logs for unusual activity, track usage patterns, and respond to potential security incidents effectively. In contrast, preventing accidental disclosure of information is not a direct function of a firewall. While firewalls enhance overall security and can indirectly help to secure sensitive information, they do not specifically address or prevent scenarios that may lead to the accidental exposure of data. Such tasks would typically fall under the broader domains of data loss prevention strategies, encryption, and user education regarding information security practices.
