Incident response is the procedure that turns a stressful event into a manageable one. The organisations that handle incidents well are not the ones with fewer incidents; they are the ones who already know who picks up the phone, what the first thirty minutes look like, and when the regulator has to be told. NIS2 has sharpened that expectation considerably: in-scope entities must submit an early warning within 24 hours of awareness and a formal incident notification within 72.
The phases are well established. Preparation makes sure the runbook, the on-call rota, and the contact list exist before they are needed. Detection and analysis decide whether a signal is a real incident and how serious it is. Containment limits the damage; eradication removes the cause; recovery brings systems back. The post-incident review captures lessons in a corrective action that feeds the next iteration of the plan. Each phase has its own evidence trail, and the audit-grade question is whether the trail can be reconstructed credibly after the fact.
The hardest part of incident response is rarely technical. It is the decision tree under uncertainty: when to escalate, when to notify the regulator, when to bring in legal counsel, when to disclose to customers. The Askara Solutions agent keeps the runbook, the decision criteria, and the notification clock visible during the incident, so the response team is making informed calls rather than reconstructing the procedure on the fly.
