Definition: The Incident Management Policy is the top-level governance document that defines what qualifies as an incident, establishes severity tiers, assigns accountability, and sets mandatory response and notification timelines.

Features:
( Ownership ) Owned by the CISO’s office for security incidents, in coordination with HR and facilities leadership for physical and personnel incidents.
( Approval ) Approved by executive management or the board before it takes effect.
( Consistency ) Without it, incident classification and escalation become inconsistent and response times unpredictable.
( Regulatory Compliance ) Prevents missed regulatory notification deadlines, such as breach disclosure laws.

FieldDescription
Incident DefinitionCriteria that distinguish an incident from a routine service event or minor issue
Severity TiersClassification levels (e.g. Critical, High, Medium, Low) with defined business-impact thresholds
Roles & ResponsibilitiesNamed roles — incident commander, SOC analyst, HR/facilities liaison, communications lead
Notification TimelinesMaximum time allowed to notify internal stakeholders, regulators, or affected parties per severity
Escalation PathChain of authority for escalating unresolved or high-severity incidents
ScopeCategories covered: security, IT operations, physical safety, HR/personnel
Review CadenceFrequency of policy review and re-approval by executive sponsors
EnforcementConsequences for non-compliance with reporting or response obligations

The policy is reviewed at least annually or after any incident that exposes a gap in classification, escalation, or notification requirements.

  • Define severity tiers in business-impact terms, not just technical terms, so non-technical stakeholders can classify correctly.
  • Align notification timelines with applicable regulatory deadlines (breach laws, contractual SLAs).
  • Keep the policy short and principle-based; put step-by-step detail in the companion process document.
  • Require executive sign-off on any change to severity thresholds or escalation authority.
  • Revisit the policy after every major incident post-mortem, not only on a fixed calendar.
