Triage and Remediation
Remediation
Using Console
Using Console
To remediate the issue of SES Identities allowing cross-account access in AWS using the AWS Management Console, follow these steps:
- Sign in to the AWS Management Console: Go to the AWS Management Console and sign in using your credentials.
- Navigate to the SES Console: In the AWS Management Console, search for “SES” in the services search bar and click on “Simple Email Service” to open the SES console.
- Select the SES Identity: In the SES console, select the SES identity (email address, domain, or email sending authorization) that you want to remediate for cross-account access.
- Check the Identity Policies: Under the “Identity Policies” section, review the policies associated with the selected SES identity to identify any cross-account access permissions.
-
Remove Cross-Account Access Permissions: To remove cross-account access permissions from the identity policy, follow these steps:
- Click on the “Edit Policy” button next to the policy that allows cross-account access.
- In the policy editor, locate the statement that grants cross-account access and delete or modify it accordingly.
- Ensure that the policy only allows necessary permissions for the SES identity without granting access to other AWS accounts.
- Save the Policy Changes: After removing the cross-account access permissions from the identity policy, click on the “Save Changes” or “Update Policy” button to save the updated policy.
- Verify the Changes: Verify that the identity policy no longer allows cross-account access by reviewing the updated policy in the SES console.
Using CLI
Using CLI
To remediate the misconfiguration of allowing cross-account access for AWS SES identities, you can follow these steps using AWS CLI:
-
List the identities in SES:
Run the following command to list all the identities in SES:
-
Get the policy for the identity:
Identify the identity (email address or domain) for which you want to restrict cross-account access and run the following command to get the policy for that identity:
-
Update the policy to restrict cross-account access:
Edit the policy to restrict cross-account access. You need to update the policy to allow access only from the AWS account that owns the SES identity. Here is an example of a policy that restricts access to the identity owner’s account:
-
Update the policy:
Run the following command to update the policy for the SES identity with the new policy that restricts cross-account access:
Replace
<IDENTITY>with the SES identity (email address or domain),<POLICY_NAME>with a name for the policy, and<POLICY_JSON>with the updated policy JSON. -
Verify the policy:
You can verify the updated policy by running the
get-identity-policiescommand again.
Using Python
Using Python
To remediate the misconfiguration of SES identities allowing cross-account access in AWS using Python, you can follow these steps:
- Identify the SES Identities: First, you need to identify the SES identities that are allowing cross-account access. You can do this by listing all the identities in your AWS account.
- Update the IAM Policy: You need to update the IAM policy attached to the SES identities to restrict cross-account access. You can achieve this by modifying the policy to allow access only from the specific AWS account where the SES identities are intended to be used.
- Use Boto3 to Modify IAM Policy: Here is a Python script using Boto3 to update the IAM policy for SES identities:
- **Replace ‘YOUR_SES_IDENTITY_ARN’ and ‘YOUR_AWS_ACCOUNT_ID’ with your actual SES identity ARN and AWS account ID in the script.
- Run the Script: Save the script in a Python file and run it in your AWS environment where you have the necessary permissions to update IAM policies for SES identities.
