Access Control in Alibaba Cloud OSS

Alibaba Cloud Object Storage Service (OSS) provides robust access control mechanisms to ensure data security and manage user permissions effectively. Below are key concepts and configurations for access control in OSS:

📌 Core Concepts

• RAM Roles: Use RAM (Resource Access Management) roles to assign permissions to users or services.

  • Example: A RAM_Role can grant specific access rights to your application.
  • Learn more about RAM roles

• Bucket Policies: Define fine-grained access rules for your bucket.

  • Supported actions: GetObject, PutObject, ListObjects, etc.
  • View Bucket policy documentation

• IP Whitelisting: Restrict access to specific IP addresses or ranges.

  • Use IP_Filter to enhance security for sensitive data.
  • 

🔒 Security Best Practices

1. Enable SSL: Always use HTTPS to encrypt data in transit.
2. Log Monitoring: Regularly check access logs for suspicious activities.
3. Temporary Tokens: Issue short-lived temporary access credentials when necessary.
