An IPS (intrusion prevention system) is more advanced than an IDS (intrusion detection system). What else does an IPS perform?

An intrusion prevention system (IPS) goes beyond the capabilities of an intrusion detection system (IDS) by not only monitoring and detecting malicious activities but also actively preventing them. This proactive approach allows an IPS to take immediate action against identified threats, such as blocking malicious traffic or severing connections.

One of the advanced techniques used by IPS is statistical anomaly detection, which analyzes network traffic patterns and behavior over time. By establishing a baseline of normal activity, the IPS can identify anomalies that may signify a potential security threat. This behavioral detection method is critical as it can uncover threats that signature-based systems might miss, especially new or unknown attacks.

While an IPS can indeed incorporate signature-based detection to identify known threats, this does not encompass its broader capabilities. False-positive detection relates to identifying and resolving mistaken alerts but isn't a function that distinguishes IPS specifically. Encryption is unrelated to the primary function of IDS or IPS systems, focusing instead on securing data in transit and at rest. Therefore, the ability to conduct statistical anomaly detection aligns well with the more advanced and proactive nature of IPS technology.
