COMPUTER FUNDAMENTALS

Detailed explanation-1: -As mentioned, NIDS (Network Intrusion Detection System) is a security technology that monitors and analyzes network traffic for signs of malicious activity, unauthorized access, or security policy violations.

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 and NIPS A network-based intrusion detection system (NIDS) detects malicious traffic on a network. NIDS usually require promiscuous network access in order to analyze all traffic, including all unicast traffic. NIDS are passive devices that do not interfere with the traffic they monitor; Fig.

Detailed explanation-4: -An intrusion detection system (IDS) is a device or software application that monitors a network for malicious activity or policy violations. Any malicious activity or violation is typically reported or collected centrally using a security information and event management system.

Detailed explanation-5: -Once an intrusion is detected, NIDS immediately shuts down the process and alerts you so you can react quickly to stop further damage. Prevents attacks. The NIDS constantly monitors network traffic to identify suspicious activity and block it before hackers are able to gain access to your system.
