A company suspects that an attacker has been attempting to gather sensitive information by intercepting traffic on its wired network. Which of the following measures is MOST effective in preventing the attacker from gaining useful information?
You selected this option
Implementing a firewall between the wired network and external systems.
You selected this option
Disabling all unused services on the network hosts.
You selected this option
Encrypting the data in transit over the network.
You selected this option
Changing the default passwords on network devices.
Encrypting the data in transit on the wired network significantly enhances security, as it renders intercepted traffic unreadable and useless to an attacker without the proper decryption key. Changing default passwords does not prevent traffic interception, although it is a basic security practice. Implementing a firewall helps regulate traffic based on security rules but does not directly prevent data interception. Disabling unused services minimizes potential exploit vectors but would not prevent an attacker from capturing traffic that is already allowed on the network.
