Plan for Incident Response

Implementation Effort: Medium
Customer IT and Security Operations teams must define and operationalize incident response workflows using Defender for Cloud and the Microsoft Defender portal.

User Impact: Low
All actions are performed by administrators and security teams; no user-facing changes or notifications are required.

Overview​

Planning for incident response in Microsoft Defender for Databases ensures that your organization can detect, investigate, contain, and recover from database-related security threats. Defender for Databases integrates with Microsoft Defender XDR and Microsoft Sentinel to provide a unified view of incidents and alerts across cloud and hybrid environments.

Key Phases of Incident Response​

  1. Detection and Triage

    • Use Defender for Cloud to monitor for suspicious database activity (e.g., SQL injection, privilege escalation).
    • In the Microsoft Defender portal, triage incidents by filtering and sorting based on severity, asset type, and exposure 1.

  2. Investigation and Analysis

    • Open the incident to view the full attack story, including affected entities, detection sources, and alert timelines.
    • Use the Evidence and Response tab to gather forensic data and understand the scope of the attack 1.

  3. Containment and Eradication

    • Take immediate actions such as:
      • Disabling compromised accounts
      • Isolating affected machines
      • Blocking malicious IP addresses 1
    • Use automation rules in Microsoft Sentinel to accelerate containment.

  4. Recovery

    • Restore affected database services and configurations to their pre-incident state.
    • Validate that all threats have been removed and that monitoring is active.

  5. Post-Incident Review

    • Document the incident, root cause, and response actions.
    • Update playbooks, detection rules, and access policies based on lessons learned.
    • Use Threat Analytics to research trends and improve future readiness 1.

This strategy supports the Zero Trust principle of "Assume Breach" by ensuring that your organization is prepared to respond quickly and effectively to database threats. Without a defined response plan, incidents may escalate, leading to data loss or prolonged downtime.
