What is the key advantage of using a hybrid IDS?

The key advantage of using a hybrid Intrusion Detection System (IDS) is that it combines the capabilities of both signature-based and anomaly-based detection methods. This blend allows for a more comprehensive approach to detecting intrusions and security threats. Signature-based detection is effective in identifying known threats based on predefined signatures, enabling quick detection of familiar attacks. On the other hand, anomaly-based detection identifies deviations from normal behavior, helping to catch new, previously unknown threats that do not have established signatures.

By leveraging both methods, a hybrid IDS can offer enhanced accuracy and adaptability in identifying a wider range of attacks, thus improving overall network security. This dual capability allows the system not only to catch known threats but also to recognize anomalous patterns that may indicate a novel attack, providing a more robust defense strategy compared to using either technology alone.
