However, network security is in many ways similar to physical security in that no one technology serves all needs-rather, a layered defense provides the best results. Organizations are increasingly looking to additional security technologies to counter risk and vulnerability that firewalls alone cannot address. Network-based intrusion detection systems (IDSs) provide around-the-clock network surveillance. The Cisco Secure Intrusion Detection System (CSIDS) is a real-time, network-based IDS designed to detect, report, and terminate unauthorized activity throughout a network.
