What are S3 Access Points?

AWS S3 Access Points are a scalable and secure way to manage data access for shared data sets in S3. Each access point is a network endpoint attached to an S3 bucket, configured with distinct permissions and network controls. This feature simplifies data access for applications, teams, and individual users, especially in large-scale environments.

Key Features of S3 Access Points

  • Customized Access Control: Create access points with specific permission sets for different use cases.
  • Simplified Data Sharing: Facilitate easy sharing of data sets among various applications and users.
  • Enhanced Security: Apply distinct access policies to each access point for secure data access.
  • Scalable Architecture: Efficiently manage data access at scale, suitable for both small and large organizations.

Creating and Managing Access Points via AWS Management Console

  1. Log In to AWS Management Console:
    • Access your AWS account and navigate to the S3 service.
  2. Access Point Creation:
    • Select the bucket for which you want to create an access point.
    • Navigate to the “Access Points” section and click “Create access point.”
    • Assign a unique name to the access point.
    • Specify network configuration and access policy. You can define the policy in JSON format, detailing permissions and access rules.
  3. Review and Save:
    • Verify the details of your access point and click “Create” to establish the new access point.

Configuring Access Points via AWS CLI

  1. Prerequisites:
    • Ensure the AWS CLI is installed and configured with appropriate permissions.
  2. Command to Create Access Point:
    • Use the create-access-point command. Provide the bucket name, access point name, and access policy. For example:
aws s3control create-access-point --bucket YOUR_BUCKET_NAME --name YOUR_ACCESS_POINT_NAME --account-id YOUR_ACCOUNT_ID --public-access-block-configuration '{"BlockPublicAcls": true}'


  • Confirm the creation of the access point using the get-access-point command:
aws s3control get-access-point --account-id YOUR_ACCOUNT_ID --name YOUR_ACCESS_POINT_NAME

Best Practices for S3 Access Points

  • Define Clear Policies: Ensure access policies are clearly defined and align with your organization’s data access requirements.
  • Regular Auditing: Periodically review and audit access point configurations to maintain
  • security and compliance.
  • Use for Large Scale Applications: Leverage access points for applications that require fine-grained access control over shared data sets.
  • Combine with Other AWS Services: Integrate access points with AWS services like IAM for enhanced security and access management.
  • Use Cases for S3 Access Points
  • Multi-tenant Applications: Provide isolated data access for each tenant in a multi-tenant application.
  • Data Analytics: Grant specific analytics teams access to relevant data sets without exposing the entire bucket.
  • Cross-Department Access: Enable different departments or teams to access shared data with distinct permissions.


AWS S3 Access Points offer a flexible, secure, and efficient way to manage access to shared data in S3 buckets. By creating dedicated access points with tailored permissions, organizations can streamline access management, enhance security, and support a wide range of data access scenarios. Whether configured via the AWS Management Console or the CLI, S3 Access Points are an essential tool for modern data management in AWS.
