Incident Response

SonicSaaS maintains a documented incident response plan covering detection, containment, and recovery from security incidents. This page summarizes the key elements.

Scope

The incident response plan covers:

  • Unauthorized access to the platform or managed firewalls
  • Credential compromise (user accounts, device credentials, API keys, encryption keys)
  • Data breach or exfiltration
  • Denial of service against the management platform
  • Supply chain compromise (dependencies, container images, CI pipeline)
  • Insider threat (unauthorized privilege escalation or data access)

Severity Classification

SeverityDefinitionResponse Target
P1 — CriticalActive breach, credential exposure, or data exfiltrationImmediate (< 1 hour)
P2 — HighVulnerability being actively exploited< 4 hours
P3 — MediumVulnerability discovered, no evidence of exploitation< 24 hours
P4 — LowSecurity improvement or hardening opportunityNext planned work cycle

Response Phases

Detection

Security incidents are detected through multiple channels:

  • Automated scanning: Static analysis, dependency scanning, container scanning, and secret detection run in CI
  • Audit trail: All mutations are logged to an immutable audit table — anomalous patterns are visible in log review
  • User reports: Team members can report suspicious activity
  • External disclosure: Vulnerability reports from external parties

Containment

Immediate containment actions depend on the incident type:

  • Compromised user account: Revoke all sessions, force password reset
  • Compromised device credentials: Rotate the password on the firewall, update credentials in SonicSaaS, review audit logs for unauthorized operations
  • Compromised encryption key: Generate a new key, re-encrypt all affected credentials
  • Compromised auth secret: Replace the secret — all active sessions are invalidated immediately
  • Database compromise: Rotate all secrets (database password, encryption keys, auth secret), force password reset for all users

Recovery

  1. Restore from backup if data integrity is compromised
  2. Verify system integrity
  3. Monitor audit logs closely for 48 hours post-recovery
  4. Re-enable any disabled features or integrations

Post-Incident

After resolution, the team conducts:

  • Timeline documentation: Complete incident chronology from detection to resolution
  • Root cause analysis: What failed and why
  • Lessons learned: What to improve
  • Action items: Security improvements tracked as issues
  • Stakeholder notification: Affected users notified if data was exposed

Evidence Preservation

For P1 and P2 incidents, the following evidence is preserved before making changes:

  • Audit event records for the incident time window
  • Activity logs for the same period
  • Application log files
  • Container image SHA used at time of incident

Annual Review

The incident response plan is reviewed annually and after any incident. Reviews include a tabletop exercise simulating a critical scenario, verification that credential rotation procedures work, and updates based on the current threat landscape.
