Evaluating Containment Effectiveness
Once containment actions are in place, the next step is to assess whether they are effective in preventing the attack from spreading and limiting the impact. Evaluating containment effectiveness involves:
Monitoring for Ongoing Activity: Continuous monitoring is essential to ensure that the containment measures are working. Security tools and systems should be used to monitor for signs of further compromise.
Reassessing Containment Measures: If the incident continues to evolve, the containment strategy may need to be adjusted. Regular reassessments help ensure that containment actions are still relevant and effective.
Feedback from the IRT: The IRT should provide feedback on the containment efforts, sharing observations about what worked and what didn’t. This feedback helps refine the incident response process and ensure that containment efforts are continuously improved.
