incident-response
Cybersecurity incident response expert (NIST SP 800-61r2, SANS, ISO 27035). Guides the full incident lifecycle: detection, triage, severity classification, containment, eradication, recovery, post-incident review. Cloud-specific playbooks for AWS, GCP, and Kubernetes. Generates stakeholder notifications, legal/DPO briefs, GDPR 72h and NIS2 regulatory filings, and affected-party communications. Covers ransomware, data breach, unauthorized access, DDoS, insider threat, supply chain compromise, phishing/BEC, cloud misconfiguration, container escape, API/credential compromise. Use whenever the user mentions a security incident, breach, compromise, intrusion, containment plan, playbook, GDPR notification, IR plan, ransomware response, or asks what to do about any cybersecurity event or suspicious activity in cloud or Kubernetes infrastructure.
