Description:
This policy ensures that trust boundaries in VPC endpoint services only allow connections from allowlisted principles. This is important to do because it helps to protect your data and resources from unauthorized access.
Rationale:
Having allowlisted principles in trust boundaries in VPC endpoint services helps to protect your data and resources from unauthorized access. By only allowing connections from allowlisted principles, you can help to prevent data breaches and other security incidents.
Impact:
If allowlisted principles are not in place in trust boundaries in VPC endpoint services, then any principle that can reach the VPC endpoint service will be able to connect to it. This could allow attackers to access your data or resources, which could have a significant impact on your business.
Default Value:
AWS will recommend that you create allowlisted principles in your trust boundaries for VPC endpoint services.
Pre-Requisite:
- You must have access to the AWS Management Console or the AWS CLI.
- You must have the IAM permissions necessary to manage VPC endpoint services.
Remediation Steps:
To ensure that allowlisted principles are in place in your trust boundaries for VPC endpoint services, you can follow these steps:
- Check the trust settings for your VPC endpoint services.
- Make sure that the trust settings only allow connections from allowlisted principles.
- If necessary, you can update the trust settings for your VPC endpoint services to only allow connections from allowlisted principles.
Test Plan:
To test whether allowlisted principles are in place in your trust boundaries for VPC endpoint services, you can follow these steps:
- Use the AWS Management Console or the AWS CLI to check the trust settings for your services.
- Try to connect to the services from a principle that is not allowlisted.
- If you are able to connect to the services, then you will need to take steps to tighten the trust settings.
Implementation Plan:
To implement this policy, you can follow these steps:
- Update the trust settings for your VPC endpoint services to only allow connections from allowlisted principles.
AWS CLI Process:
To use the AWS CLI to ensure that allowlisted principles are in place in your trust boundaries for VPC endpoint services, you can use the following commands:
aws ec2 update-vpc-endpoint --service-name service-name --vpc-id vpc-id --policy file://trust-policy.json
Using AWS GUI:
To use the AWS Management Console to ensure that allowlisted principles are in place in your trust boundaries for VPC endpoint services, you can follow these steps:
- Go to the AWS Management Console and sign in to your account.
- Click on the "VPC" service.
- Click on the "Endpoints" tab.
- Select the VPC endpoint services that you want to update the trust settings for.
- Click on the "Trust Relationships" tab.
- Update the trust relationships for the services to only allow connections from allowlisted principles.
Backout Plan:
To back out of this policy, you can follow these steps:
- Update the trust settings for your VPC endpoint services to allow connections from all principles.
Note:
- This policy does not apply to VPC endpoint services that are not using a custom trust policy.
