Network Security - Network Intrusion Detection System
Monitor your network traffic for signs of malicious activity or policy violations. Analyzing network traffic in real-time, looking for patterns or anomalies that indicate an attack or intrusion is taking place in your environment.
A variety of techniques to detect intrusions, including signature-based detection, anomaly-based detection, and behavioral-based detection. Signature-based detection compares network traffic against a database of known attack patterns or "signatures." Anomaly-based detection looks for traffic that deviates from normal patterns or "anomalies." Behavioral-based detection is based on the observation of normal behavior of the systems and network, and any deviation from it is considered as an intrusion.
It is important to note that NIDS is a reactive security measure, meaning that it can only detect and alert on intrusions that have already occurred. It cannot prevent an intrusion from happening in the first place. Therefore, it is often used in conjunction with other security measures.
