Which of the following is most closely associated with attempting to actively prevent network intrusion?
Correct Answer: C
An intrusion prevention system (IPS) is a network security tool that continuously monitors network traffic for malicious activity and takes action to prevent it, such as reporting, blocking, or dropping it. An IPS is different from an intrusion detection system (IDS), which only detects and alerts about threats, but does not stop them.
A firewall is a device or software that filters network traffic based on predefined rules, but it does not analyze the traffic for anomalies or signatures of known attacks. A VPN is a virtual private network that creates a secure tunnel between two endpoints, but it does not prevent intrusions from within the network or from compromised endpoints.
