Detection Rules¶

Log Analysis¶

rules:
  - name: failed-login-threshold
    description: Multiple failed logins
    severity: high
    condition: |
      event.type == "auth_failure"
      AND count(30m) > 5
    action: alert_and_block

  - name: unusual-data-access
    description: PHI access outside normal hours
    severity: medium
    condition: |
      event.type == "data_access"
      AND event.data_type == "phi"
      AND NOT event.time BETWEEN "06:00" AND "22:00"
    action: alert_and_audit

Network Monitoring¶

rules:
  - name: data-exfiltration
    description: Large outbound data transfer
    severity: critical
    condition: |
      bytes_out > 1GB
      AND destination NOT IN allowed_destinations
    action: alert_and_block

  - name: suspicious-connection
    description: Connection to known bad IP
    severity: high
    condition: |
      destination IN threat_intel_list
    action: alert_and_block

Incident Response¶

Automated Response¶

playbook: phishing-detected
trigger: phishing_alert
steps:
  - name: isolate
    action: quarantine_email

  - name: block
    action: block_sender_domain

Manual Response¶

1. Detection - Alert received
2. Triage - Assess severity
3. Containment - Limit spread
4. Investigation - Root cause
5. Eradication - Remove threat
6. Recovery - Restore normal
7. Lessons Learned - Improve

)

# Update certificates
secunit.update_certificates(
    domains=["api.brainsait.com"],
    provider="letsencrypt"
)
