It aims to prevent propagation of the threat, preserve the evidence, and restore parts of the network not affected by the breach. Strategies for containment might include isolating affected systems from the network, utilizing network segmentation, deploying intrusion prevention systems, blocking specific IPs, or disabling connectivity for affected user accounts. Incident containment is crucial to minimize the impact of the incident, reduce the risk of compromise to other systems, and mitigate disruption to critical organizational functions.
