An attack on a network is BEST blocked using which of the following?

An Intrusion Prevention System (IPS) device placed inline is best suited to block attacks on a network actively. Being inline allows the IPS to analyze and take action on the traffic as it passes through the device, effectively preventing malicious traffic from reaching its target. The IPS can detect and block a wide range of attacks in real-time by using various detection methods, such as signature-based detection, anomaly detection, and policy-based detection. Unlike Host-based Intrusion Prevention Systems (HIPS), web proxies, or load balancers, an inline IPS is specifically designed to inspect and act on incoming and outgoing network traffic to prevent attacks before they reach network devices or applications.
