Answer :
Final answer:
An IDS, or Intrusion Detection System, acts as a digital watchdog by monitoring networks for suspicious activity through signature-based and anomaly-based detection methods, enabling security personnel to react effectively.
Explanation:
What is an IDS?
An Intrusion Detection System (IDS) is a security tool that monitors networks and systems for suspicious activity, acting as a digital watchdog against potential threats.
How does an IDS work?
IDS systems operate through signature-based detection, identifying known attack patterns, and anomaly-based detection, focusing on unusual behavior compared to normal network activity, to alert security personnel upon detecting threats.
Choosing the right IDS
Selection depends on factors like network size, threat landscape, false positive rate, and integration compatibility with other security tools, ensuring optimal security.
