🥌Cloud Security Baseline for Azure AI Document Intelligence

1. Identity and Access Management

a. Azure Active Directory (AAD) Integration

• Ensure all users and applications authenticate using Azure Active Directory.

• Enforce Multi-Factor Authentication (MFA) for all users.

• Utilize role-based access control (RBAC) to assign permissions. Use least privilege principle.

b. Service Principal and Managed Identities

• Use service principals for application authentication.

• Utilize managed identities for Azure resources to avoid hardcoding credentials.

2. Network Security

a. Network Isolation

• Deploy Azure AI Document Intelligence within a virtual network (VNet).

• Use Network Security Groups (NSGs) to control inbound and outbound traffic to resources.

b. Private Endpoints

• Use Private Link to enable access to Azure AI Document Intelligence over a private endpoint in your VNet.

3. Data Security

a. Data Encryption

• Ensure data at rest is encrypted using Azure Storage Service Encryption.

• Use HTTPS for data in transit to ensure secure transmission.

b. Key Management

• Use Azure Key Vault to manage and store cryptographic keys.

• Rotate keys periodically and configure alerts for key access.

4. Monitoring and Logging

a. Activity Logs and Metrics

• Enable Azure Monitor and Application Insights to collect logs and metrics.

• Set up diagnostic logs for resource activity tracking.

b. Security Alerts

• Configure Azure Security Center to monitor security configurations and practices.

• Set up alerts for suspicious activities and security recommendations.

5. Compliance and Governance

a. Compliance Policies

• Regularly review and comply with industry standards and regulatory requirements.

• Use Azure Policy to enforce compliance policies and standards.

b. Resource Management

• Tag resources with appropriate metadata for easier tracking and management.

• Use Azure Blueprints to define and standardize deployments.

6. Incident Response

a. Security Incident Response

• Develop and document an incident response plan.

• Use Azure Security Center for centralized management and response to security incidents.

7. Backup and Disaster Recovery

a. Backup Strategy

• Implement regular backups for all critical data.

• Use Azure Backup to manage and automate backup processes.

b. Disaster Recovery Plan

• Develop and test a disaster recovery plan.

• Utilize Azure Site Recovery to ensure business continuity.

Implementation Steps

1. Initial Setup

   • Configure Azure Active Directory with necessary roles and policies.

   • Set up VNets, NSGs, and private endpoints.

2. Data Protection

   • Enable encryption for data at rest and in transit.

   • Set up Azure Key Vault for key management.

3. Monitoring and Compliance

   • Enable Azure Monitor and Application Insights.

   • Configure Azure Security Center and define compliance policies.

4. Incident and Backup Management

   • Develop incident response and disaster recovery plans.

   • Implement Azure Backup and Azure Site Recovery.

Regular Review and Updates

• Regularly review security configurations and policies.

• Keep up-to-date with Azure updates and security best practices.
