In science:

The detection time is important for intrusion detection applications, measuring how quickly a sensor network can detect a randomly located intruder.
Dynamic Coverage of Mobile Sensor Networks
The time scales of such time durations are also very important for network planning; they present the time granularity of the intrusion detection capability that a mobile sensor network can provide.
Dynamic Coverage of Mobile Sensor Networks
Specifically, we studie d the coverage measures related to the area coverage and intrusion detection capability of a mobile sensor network.

IDPS: An Integrated Intrusion Handling Model for Cloud
Intrusion Prevention System in Cloud Computing There are only a few works that talked about IPS in Cloud Computing. Generally an IPS sits inline on the network and monitors it, and when an event occurs, it takes action, based on prescribed rules.
IDPS: An Integrated Intrusion Handling Model for Cloud
Others, however, think in broader terms and consider the IPSs as yet another tool in the security infrastructure that could help prevent intrusions. IPS has been developed out of IDS but, the two are really different security products that have different functionalities and strengths as shown in Table 4 .
IDPS: An Integrated Intrusion Handling Model for Cloud
The Intrusion Detection Service (IDS) service increases a Cloud’s security level by providing two methods of intrusion detection.
