Open-source NIDS Vs Commercial NIDS

Locked

overview of technological issues associated with IDS, Further more by looking at the network bases systems and can argue that due to the high bandwidth requirements that are needed by network based intrusion detection systems (NIDS) the optimum approach may be to use an open source code and then invest funds in an expert that can tailor the programme to the needs of the client rather than buying a vendor version of a NIDS. Intrusion detection systems (IDS) are one of the fastest growing technologies within the security space. Unfortunately, many companies find it hard to justify acquiring IDS systems due to their perceived high cost of ownership. However, not all IDS systems are prohibitively expensive.

Can open source Intrusion detection systems can be effective and financially beneficial?
