🚨 About Incident Response Center

The Incident Response Center provides automated detection, structured containment, and rapid recovery capabilities for all security incidents affecting the Nexxus platform. Guided by a full PICERL lifecycle (Preparation, Identification, Containment, Eradication, Recovery, Lessons Learned), the IRC integrates automated actions, human escalation chains, and detailed playbooks for the most common and severe threat scenarios.

📋 Response Playbooks

👤Account Compromise HIGH▼
Triggered when behavioral AI score exceeds 80 or a canary token/honeypot fires against a specific account. Immediate revocation of all sessions and forced re-authentication.
  • Revoke all active JWT tokens for the affected account immediately
  • Capture forensic snapshot: last 200 requests, IP list, UA strings
  • Force account lockout pending MFA re-enrollment
  • Notify account owner via secondary verified contact channel
  • Run behavioral diff: compare session to 30-day baseline
  • Escalate to security team if attacker IP matches known APT range
🌊DDoS Attack CRITICAL▼
Activated when request rate exceeds 10,000 req/s per origin segment, or WAF triggers spike above baseline by 500%. Automated rate limiting engages within 30 seconds.
  • Activate rate limiting tier 3 (1000 req/min per IP, 100 per segment)
  • Enable geo-blocking for attacking country ranges if concentrated
  • Switch to challenge mode — all requests require proof-of-work
  • Notify leadership and activate DDoS response retainer
  • Log all attacking IPs for post-incident threat intelligence feed
  • Scale infrastructure horizontally if SLA breach threshold approached
💾Data Breach CRITICAL▼
Triggered by canary token exfiltration, anomalous bulk data exports, or external breach notification. 72-hour regulatory notification clock starts immediately.
  • Isolate affected database segments and rotate all encryption keys
  • Preserve all logs in write-once storage for forensic chain of custody
  • Identify affected records and data classification level
  • Notify legal and compliance team within 1 hour
  • Notify affected users within 24 hours with plain-language impact statement
  • File regulatory notifications (GDPR Art. 33) within 72 hours if required
🔒Ransomware CRITICAL▼
If Falco runtime monitoring detects mass file encryption patterns or ransom note creation, immediate network isolation of affected hosts is triggered automatically.
  • Immediately isolate all affected hosts at network layer (automated)
  • Snapshot all volumes before any remediation activity
  • Do not pay ransom — restore from last verified clean backup
  • Conduct full malware analysis on isolated copy
  • Identify patient-zero host and initial access vector
  • Engage law enforcement and report to CISA if critical infrastructure
🕵️Insider Threat HIGH▼
Activated when behavioral drift monitoring identifies a trusted account exhibiting data hoarding, privilege abuse, or communication patterns consistent with exfiltration preparation.
  • Do not alert the suspected insider — maintain covert monitoring only
  • Silently revoke sensitive permissions to least-privilege baseline
  • Collect 90-day behavioral audit trail for legal review
  • Involve HR and legal before any confrontation or termination
  • Preserve all evidence with legal hold orders
  • Conduct access review across all systems the individual touched
📦Supply Chain Attack CRITICAL▼
Triggered if Cosign signature verification fails, SBOM diff detects unexpected new dependencies, or Falco alerts on unexpected syscalls from a container workload post-deploy.
  • Immediately roll back affected deployments to last signed good version
  • Quarantine all running instances of the affected image
  • Generate fresh SBOM and diff against known-good baseline
  • Audit all code merged since last clean scan for tampering
  • Revoke and re-issue all signing keys used in the compromised pipeline
  • Notify upstream dependency maintainers and CISA if applicable
