types of idps devices
Currently, there are two types of IPSs that are similar in nature to IDS. They consist of host-based intrusion prevention systems (HIPS) products and network-based intrusion prevention systems (NIPS).
There is a wide spectrum of IDS, varying from antivirus software to hierarchical systems that monitor the traffic of an entire backbone network. The most common classifications are network intrusion detection systems (NIDS) and host-based intrusion detection systems (HIDS).
