6. Security Best Practices

Security is a shared responsibility between Alibaba Cloud and its customers. Alibaba Cloud provides a secure infrastructure, but it’s your responsibility to configure your resources securely and implement appropriate security measures.

  • 6.1 Identity and Access Management (IAM):

    Use Resource Access Management (RAM) to control access to your Alibaba Cloud resources.

    • Principle of Least Privilege: Grant users only the minimum permissions they need to perform their tasks.
    • Multi-Factor Authentication (MFA): Enable MFA for all users, especially those with administrative privileges.
    • Regularly Review Permissions: Review user permissions periodically to ensure they are still appropriate.
    • Use Roles: Instead of granting permissions directly to users, create roles with specific permissions and assign users to those roles.

  • 6.2 Network Security:

    • VPC: Use VPCs to create isolated network environments for your applications.
    • Security Groups: Security groups act as virtual firewalls for your ECS instances. Configure security group rules to allow only necessary inbound and outbound traffic.
    • Network ACLs: Network ACLs provide an additional layer of network security at the subnet level.
    • SLB: Use Server Load Balancers to distribute traffic and improve application availability. Configure SSL/TLS certificates for secure communication.
    • WAF and Anti-DDoS: Protect your applications from web attacks and DDoS attacks.

  • 6.3 Data Encryption:

    • Data at Rest: Encrypt your data at rest using services like KMS and OSS bucket encryption.
    • Data in Transit: Use HTTPS for communication between your applications and clients. Use VPN Gateway or
