24Incident Mitigation (RS.MI)

In the ballet of cybersecurity incident management, containment and eradication perform as critical movements—where swift, decisive actions isolate danger and purge threats, each step choreographed with precision and insight, ensuring the dance of defense evolves stronger with every performance.

In the critical stages of incident management, containment and eradication are essential. For containment, strategies are designed to quickly limit the spread of an incident within the network, utilizing methods such as network segmentation, the deployment of endpoint detection and response (EDR) tools, and stringent communication controls. These measures, complemented by the coordinated efforts of IT teams for emergency responses and staff training on their specific roles, lay the groundwork for effective incident management. Following containment, the focus shifts to the eradication phase, where the objective is to remove the threat from the system altogether. This involves identifying and eliminating malicious payloads, conducting root cause analyses to prevent future occurrences, and systematically restoring affected systems to secure states. Both phases emphasize the importance of detailed documentation and post-incident analysis to refine protocols and enhance future response capabilities, ensuring a robust defense against cyber threats.
