Azure Audit Logs Fix

Learn how to fix exposed audit logs in Azure environments. Follow step-by-step guidance for PCI-DSS compliance.

Why It Matters

The core goal is to quickly remediate exposed audit logs that contain sensitive operational and security information in your Azure environment before they lead to compliance violations or security breaches. Fixing audit log exposures in Azure is critical for organizations subject to PCI-DSS, as these logs often contain access patterns, authentication events, and system activities that could reveal sensitive information about cardholder data environments and security controls.

Primary Risk: Shadow data in audit logs containing sensitive operational and security information

Relevant Regulation: PCI-DSS Payment Card Industry Data Security Standard

Rapid remediation of audit log exposures maintains audit trail integrity, prevents information disclosure, and ensures compliance with logging and monitoring requirements.

Prerequisites

Permissions & Roles

  • Azure Security Administrator role
  • Log Analytics Contributor permissions
  • Storage Account Contributor access

External Tools

  • Azure CLI or PowerShell
  • Cyera DSPM account
  • Azure Monitor access

Prior Setup

  • Azure Monitor configured
  • Log Analytics workspace created
  • Diagnostic settings enabled
  • RBAC policies established

Introducing Cyera

Cyera is a modern Data Security Posture Management (DSPM) platform that discovers, classifies, and continuously monitors your sensitive data across cloud services. By automating the detection and remediation of exposed audit logs in Azure using advanced AI and content analysis, Cyera ensures you can quickly secure operational data and maintain PCI-DSS compliance requirements for audit trail protection.

Step-by-Step Guide

1
Identify exposed audit log locations

Use Cyera's discovery capabilities to scan Azure storage accounts, Log Analytics workspaces, and Event Hubs for audit logs that are publicly accessible or have overly permissive access controls.

az monitor diagnostic-settings list --resource "/subscriptions/{subscription-id}/resourceGroups/{resource-group}"

2
Secure audit log access controls

Implement proper RBAC controls on storage accounts and Log Analytics workspaces containing audit logs. Remove public access and limit permissions to only authorized security and compliance personnel.

az storage account update --name "auditlogs" --resource-group "security-rg" --public-network-access Disabled

3
Configure secure log retention and archival

Set up proper retention policies for audit logs to meet compliance requirements while ensuring logs are stored securely. Configure lifecycle management to automatically archive older logs to secure, cost-effective storage tiers.

4
Implement continuous monitoring and alerting

Set up Azure Monitor alerts to detect unauthorized access attempts to audit logs. Create automated workflows that trigger when audit log access patterns indicate potential security issues or compliance violations.

Best Practices & Tips

Access Control Management

  • Use Azure RBAC with principle of least privilege
  • Implement conditional access policies
  • Regularly audit log access permissions

Log Retention & Archival

  • Set appropriate retention periods for compliance
  • Use Azure Blob lifecycle management
  • Implement secure archival to cold storage

Common Pitfalls

  • Forgetting to secure legacy log storage accounts
  • Not monitoring for unauthorized log access
  • Inadequate retention policies for compliance needs
