Solution

The Intrusion Detection System (IDS) method that searches for intrusion or attack attempts by recognizing patterns or identifying entities listed in a database is the Signature-based IDS.

Here's a step-by-step explanation:

  1. An Intrusion Detection System (IDS) is a device or software application that monitors a network or systems for malicious activity or policy violations.

  2. There are several methods that IDS use to detect intrusions. These include Signature-based IDS, Heuristics-based IDS, Anomaly-analysis-based IDS, and Stateful-inspection-based IDS.

  3. Among these, the Signature-based IDS is the one that searches for intrusion or attack attempts by recognizing patterns or identifying entities listed in a database.

  4. This method works by comparing the information in its database to observed events to identify possible incidents, logging information about them, attempting to stop them, and reporting them to security administrators.

  5. The database in a Signature-based IDS contains the patterns, known as signatures, of common and well-known attacks.

  6. When the IDS detects a match between the observed pattern and a pattern in its database, it raises an alert.

So, the answer to your question is Signature-based IDS.
