Episode 25 — A.5.5–5.6 — Contact with authorities; Special interest groups
A.5.5 requires organizations to establish and maintain appropriate contact with relevant authorities, such as regulators, law enforcement, and national or sector Computer Security Incident Response Teams (CSIRTs). For the exam, note that readiness includes identifying which authorities are competent by jurisdiction and topic, documenting when and how to contact them, and assigning roles authorized to initiate outreach. A.5.6 adds engagement with special interest groups—industry bodies, information sharing communities, and standards forums—to enhance situational awareness and best-practice adoption. Together, these controls reduce response latency and improve legal and operational alignment during incidents.
In application, teams maintain a registry with validated contact details, secure channels, time zones, and escalation criteria tied to incident severity and data breach thresholds. Pre-approved templates and legal review accelerate notifications while preserving confidentiality and evidence integrity. Participation in ISACs/ISAOs or vendor advisories brings early warning on vulnerabilities and threat campaigns, feeding risk assessment and patch prioritization. Pitfalls include stale contact lists, unclear triggers, and ad hoc communications that violate breach disclosure rules. Best practice includes periodic contact drills, liaison roles, and integration with crisis management and public relations to maintain a consistent narrative. Candidates should be ready to describe how these relationships are audited, how lessons learned feed improvements, and how proactive participation turns external networks into force multipliers for resilience.
