Azure Security Benchmark

Introduction to Azure Security Benchmark

• The Azure Security Benchmark (ASB) is a set of best practices and recommendations provided by Microsoft for securing Azure services.
• It is designed to help organizations improve their security posture by implementing controls that are aligned with well-known security frameworks such as CIS Controls and NIST SP 800-53.
• The ASB includes various controls categorized into different domains to ensure comprehensive coverage of security aspects.
• Below are the primary categories and some example controls within each category:

1. Network Security
   • Implement secure network configurations: Use Network Security Groups (NSGs) to control inbound and outbound traffic.
   • Secure the connectivity to Azure services: Use private endpoints to connect securely to Azure services.
2. Identity Management
   • Strengthen authentication: Implement Multi-Factor Authentication (MFA) for all users.
   • Secure privileged access: Use Azure AD Privileged Identity Management (PIM) to manage, control, and monitor access to important resources.
3. Privileged Access
   • Limit the number of privileged accounts: Regularly review and minimize the number of accounts with administrative privileges.
   • Monitor and audit privileged activity: Enable logging and monitoring for privileged account activities.
4. Data Protection
   • Ensure data encryption at rest: Use Azure Disk Encryption and encryption features for databases and storage accounts.
   • Encrypt data in transit: Use TLS/SSL to secure data in transit.
5. Asset Management
   • Inventory and manage assets: Maintain an inventory of all Azure resources and ensure they are managed.
   • Secure asset configurations: Regularly assess and remediate vulnerabilities in Azure resources.
6. Logging and Monitoring
   • Enable logging: Use Azure Monitor and Azure Security Center to enable and collect logs.
   • Monitor security configurations and events: Use Azure Sentinel for security information and event management (SIEM).
7. Incident Response
   • Prepare for incident response: Develop and maintain an incident response plan.
   • Detect and respond to incidents: Use Azure Security Center to detect and respond to security incidents.
8. Posture and Vulnerability Management
   • Assess security posture: Regularly use Azure Security Center to assess the security posture of your Azure environment.
   • Manage vulnerabilities: Use Azure Defender for continuous vulnerability management.
9. Backup and Recovery
   • Ensure data backup: Implement regular backups for all critical data using Azure Backup.
   • Test recovery procedures: Regularly test your backup and recovery procedures.
10. Governance and Strategy
    • Define security governance: Establish security policies and ensure they are enforced across the organization.
    • Align with compliance requirements: Ensure your Azure environment meets regulatory and compliance requirements.
