Security administration plays a vital role in network management tasks. The Intrusion Detection Systems (IDS) are primarily designed to protect the availability, confidentiality and integrity of critical network information systems. There are plenty of IDSes to choose from, both commercial and open source. Since most of the commercial intrusion detection systems are at typically thousands of dollars and they tend to represent a significant resource requirement in themselves, for small networks, use of such IDS is not feasible.
