Explanation:
This is one of the features of intrusion detections, instead of being pro-active, it has
a reactive behavior. When we set an IDS system inside of our network or hosts, the IDS agent is
constantly monitoring in real time what activities are being performed in the infrastructure. If the
IDS founds a malicious activity taking place it can take actions against it like disabling interfaces,
alerting the administrators or sending network attacks to the source to put it out of service.
As a difference to the detective behavior of IDS, we can also increase the security with practices
like hardening our systems ,this is considered a preventive practice.
