Which is the RECOMMENDED configuration mode for sensors for an intrusion prevention system (IPS) if the prevention capabilities will be used?
Correct Answer: C
Inline is the recommended configuration mode for sensors for an intrusion prevention system (IPS) if the prevention capabilities will be used. An IPS is a network security device that monitors and analyzes the network traffic for malicious or anomalous activities, and takes actions to block or stop them. An IPS sensor is the component that performs the detection and prevention functions of the IPS. An IPS sensor can be configured in different modes, such as active, passive, inline, or span. Inline mode means that the IPS sensor is placed directly in the network traffic path, and can modify, drop, or redirect the packets as they pass through.
Inline mode enables the IPS sensor to use its prevention capabilities effectively, as it can stop the attacks in real time, before they reach their intended targets. References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 7: Security Operations, page 365.
