Detailed explanation-1: -Signature-based: Signature-based IDS detects possible threats by looking for specific patterns, such as byte sequences in network traffic, or known malicious instruction sequences used by malware. This terminology originates from antivirus software, which refers to these detected patterns as signatures.
Detailed explanation-2: -An IDS monitors traffic to and from all devices on a network. The system operates behind a firewall as a secondary filter for malicious packets and primarily looks for two suspicious clues: Signatures of known attacks.
Detailed explanation-3: -What it is: Signature-based and anomaly-based detections are the two main methods of identifying and alerting on threats. While signature-based detection is used for threats we know, anomaly-based detection is used for changes in behavior.
