1.7.4 Case Study: Network Intrusion Detection Systems (NIDS)

Network Intrusion Detection Systems (NIDS) are designed to monitor network traffic and detect potential attacks. There are two main types of NIDS:

1. Signature-based NIDS: Detects attacks by comparing network traffic against a database of known attack signatures. This approach is effective for identifying known threats but cannot detect new or unknown attacks.
   
2. **Anomaly-based N...
