The acronym NIDS/NIPS stands for Network Intrusion Detection System and Network Intrusion Prevention System. These systems are critical in network security as they monitor network traffic for suspicious activities and potential threats.
A Network Intrusion Detection System (NIDS) is designed to detect unauthorized access or anomalies within the network by analyzing the traffic and identifying patterns that may indicate a security breach. When malicious activity is detected, the NIDS can alert administrators to take action.
On the other hand, a Network Intrusion Prevention System (NIPS) not only detects potential threats like an NIDS but also takes immediate actions to prevent those threats from causing harm, such as blocking the traffic from the identified malicious source or terminating user sessions.
This dual function of detecting and preventing intrusions is why this choice accurately reflects the purpose of these systems in securing network environments. The other options do not accurately describe the functionality or terminology associated with network security systems, which is essential to understand when discussing intrusion detection and prevention technologies.
