Security Incident Classification

Incident Classification Overview

Incident classification categorizes security events by type, severity, and impact enabling appropriate response prioritization and resource allocation. Consistent classification ensures effective incident management.

Severity Levels

Define severity levels (Critical, High, Medium, Low) based on impact to confidentiality, integrity, and availability. Critical incidents threaten critical systems or sensitive data requiring immediate response.

Incident Types

Categorize incidents by type: malware infection, unauthorized access, data breach, denial of service, insider threat, physical security, or policy violation. Type-specific response procedures ensure appropriate handling.

Impact Assessment

Assess impact considering affected systems criticality, data sensitivity, number of users impacted, business process disruption, regulatory implications, and potential reputation damage.

Response Prioritization

Prioritize response based on severity and impact, allocate resources appropriately, escalate high-severity incidents, and maintain documented classification criteria ensuring consistent decision-making across incident response team.
