Escalation Processes and Decision Making

Escalation processes and decision-making are vital components of an effective information security incident management framework.

These processes ensure that security incidents, based on their severity and potential impact, are promptly communicated to the appropriate decision-makers and responders at various levels.

Efficient escalation minimizes delays, allocates the right resources, and ensures that critical incidents receive the attention necessary to contain and resolve threats swiftly, safeguarding organizational assets and maintaining business continuity.

Escalation Process 

The escalation process involves systematically reviewing incident significance and determining when to notify higher authority or external parties.

It includes clearly defined triggers, roles, responsibilities, and communication pathways. The process typically follows a tiered approach that corresponds to incident severity and complexity.

Initial Escalation: Handled by frontline or local IT/security teams upon the first detection or suspicion of an incident. Typically involves confirming the incident and executing initial containment.

Intermediate Escalation: If the incident is confirmed to have a wider impact or requires more expertise, it is escalated to department heads, senior IT/security personnel, or specialized response teams.

Senior/Executive Escalation: Severe incidents affecting customer data, critical infrastructure, or legal compliance are escalated to senior management and executive stakeholders promptly.

External Escalation: As necessary, notify external entities such as regulatory bodies, law enforcement, vendors, or Computer Emergency Response Teams (CERTs).

Decision-Making Considerations

Effective decision-making during escalation balances urgency, impact, and available resources. The decision criteria often include:

1. Incident Severity: Level of threat to confidentiality, integrity, availability, reputation, or compliance.

2. Scope and Spread: How many systems, users, or business units are affected?

3. Potential Business Impact: Financial loss, downtime, customer trust, and legal ramifications.

4. Response Capability: Availability of internal resources and expertise to manage an incident at the current level.

5. Regulatory Requirements: Mandatory reporting timelines and notifications.
