Why It Matters

The core goal is to secure every audit log storage location within your Azure environment, preventing unauthorized access to operational records that could reveal sensitive activities, user behaviors, and system configurations. Protecting audit logs in Azure is essential for organizations subject to GDPR, as these logs often contain personal data traces and activity patterns that must be safeguarded from data exposure incidents.

Primary Risk: Data exposure through unsecured audit logs

Relevant Regulation: GDPR Data Protection Regulation

Implementing comprehensive audit log protection ensures compliance requirements are met while maintaining operational transparency and forensic capabilities.

Prerequisites

Permissions & Roles

  • Azure Security Administrator or Owner role
  • Log Analytics Contributor permissions
  • Azure Monitor permissions for diagnostic settings

External Tools

  • Azure CLI or PowerShell
  • Cyera DSPM account
  • Azure Policy Management access

Prior Setup

  • Azure subscription with resources
  • Log Analytics workspace configured
  • Azure Monitor diagnostic settings enabled
  • Resource access policies defined

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 leveraging AI-powered natural language processing (NLP) and pattern recognition, Cyera automatically identifies sensitive information within audit logs, detects misconfigurations in log storage permissions, and ensures your Azure audit trail remains secure while maintaining GDPR compliance in real time.

Step-by-Step Guide

1
Configure secure audit log storage

Set up Log Analytics workspaces with proper access controls and ensure all Azure resources have diagnostic settings configured to send audit logs to secure, centralized locations.

az monitor diagnostic-settings create --resource [resource-id] --logs '[{"category": "AuditLogs", "enabled": true}]'

2
Implement access controls and encryption

In the Cyera portal, navigate to Integrations → DSPM → Add new. Select Azure, provide your service principal credentials, and configure scanning to identify improperly secured audit log repositories and excessive permissions.

3
Set up monitoring and alerting

Configure Azure Policy to enforce audit log protection standards and integrate Cyera's AI-powered monitoring to detect unauthorized access attempts or configuration drift that could expose audit data.

4
Validate security posture and remediate

Review Cyera's assessment of your audit log security posture, prioritize high-risk findings such as publicly accessible log storage or overly permissive access policies, and implement automated remediation workflows.

Best Practices & Tips

Access Control Management

  • Implement least-privilege access to log workspaces
  • Use Azure RBAC for granular permissions
  • Enable multi-factor authentication for log access

Encryption & Retention

  • Enable customer-managed keys for log encryption
  • Configure appropriate retention policies
  • Implement secure log archiving strategies

Common Pitfalls

  • Leaving default public access on storage accounts
  • Over-permissive contributor roles on log workspaces
  • Neglecting to encrypt log data at rest and in transit
