Export Logs to Long-Term Storage for Financial Services & Banking

How financial services & banking organizations should implement LOG-02 for Microsoft 365 security and compliance.

Financial Services & Banking organizations face unique security challenges when managing Microsoft 365 environments. The LOG-02 control (Export Logs to Long-Term Storage) is particularly important for this sector due to soc2 and pci-dss requirements.

Why Financial Services & Banking Organizations Need This Control

Financial Services & Banking organizations face specific regulatory requirements including soc2, pci-dss, nist-800-53, iso27001. The LOG-02 control helps address these requirements by:

  • Audit logs are exported to Log Analytics workspace or external SIEM
  • Retention is configured for at least 1 year
  • Sign-in logs and audit logs are both included

Default Entra log retention is 30-90 days. APT attacks often go undetected for months. Long-term retention enables forensic investigation of compromises that happened weeks or months ago.

Industry-Specific Considerations

When implementing LOG-02 in a financial services & banking environment, consider:

  • **Regulatory requirements**: soc2, pci-dss, nist-800-53 may mandate specific configurations
  • **Risk tolerance**: Financial Services & Banking organizations typically have moderate to low risk tolerance
  • **Audit frequency**: Plan for regular compliance reviews
  • **Documentation**: Maintain detailed records for regulatory inspections

Implementation Steps

To implement LOG-02 in your Microsoft 365 environment:

  • Audit logs are exported to Log Analytics workspace or external SIEM

  • Sign-in logs and audit logs are both included

This control requires manual implementation through the Entra admin center.
