Answer yes if your organisation's Incident Response Plan contains a section for classifying information security events. Please reference the section of any previously provided plan in the notes.
An Incident Response Plan (IRP) is a crucial document that outlines the operational steps that must be taken when an unexpected or disruptive event occurs. The plan can be invoked for both security and non-security incidents and should be an organic and operational document used to restore service and co-ordinate a response.
A good IRP will categorise incidents based on the cause of the incident and the severity of its impact. For example, a security incident involving confidential data disclosure may require a different response when compared with an operational incident that causes a temporary service disruption.
Security incidents are classified with a severity rating. Severity is usually indicated with P (priority) notation, with a P1 incident being the highest severity, requiring maximum escalation to executive management and a formal co-ordinated response.
Ensure your plan has a method for categorising the type and priority of any incidents that cause the plan to be invoked. It can help to have a security consultant review your company's incident response plan to ratify its robustness.
