Incident Response classification levels

Not all incidents are equal:

• Severity

• Priority

• Organization culture

Severity levels

Often difficult to measure completely

May be frequently adjusted and IT landscape changes (cloud, etc)

Must include input from upper management and other parts of the organization

Common methodology

Urgency

How quickly will the damage continue to grow while the incident is still ongoing?

Impact

How widely is the impact felt, how many users or customers are affected and what will be the cost of the impact?

Each urgency and impact have their own ratings, which are sometimes combined to calculate priority

Include other data in criteria

Risk assessments already performed by IT risk group

Business Impact Analysis data
