Detailed explanation-1: -Network intrusion detection system (NIDS) Monitors inbound and outbound traffic to identify suspicious traffic.
Detailed explanation-2: -Network intrusion detection systems (NIDS) attempt to detect cyber attacks, malware, denial of service (DoS) attacks or port scans on a computer network or a computer itself. NIDS monitor network traffic and detect malicious activity by identifying suspicious patterns in incoming packets.
Detailed explanation-3: -NIDS systems utilise a combination of signature and anomaly-based detection methods. Signature-based detection involves comparing the characteristics of collected data packets against signature files that are known to be malicious.
Detailed explanation-4: -The NIDS alerts the network administrator if the traffic matches a known signature. Signature-based detection is effective at identifying known attacks, but it cannot detect new or unknown attacks.
