Definition

An Intrusion Detection System (IDS) is a security solution that monitors network traffic or system activities for malicious behavior or policy violations, alerting administrators to potential threats.

Used Cases

• Used by organizations to detect potential cyberattacks, such as malware infections, DDoS attacks, or unauthorized access attempts.• Applied in compliance frameworks to meet security monitoring requirements.

FAQs

What is the difference between an IDS and an IPS?

An IDS detects and alerts administrators to potential threats, while an IPS takes action to block or prevent the threat in real time.

How does an IDS detect malicious activity?

An IDS uses signature-based or anomaly-based detection techniques to identify malicious activity based on known attack patterns or deviations from normal behavior.

What are the limitations of an IDS?

An IDS can generate false positives, and it does not actively block threats, making it important to use in conjunction with other security tools.
