Using Console
To remediate suspicious access to data services in AWS IAM, you can follow these steps using the AWS Management Console:
- Sign in to the AWS Management Console (https://console.aws.amazon.com/iam/).
- Go to the IAM dashboard by selecting “Services” in the top menu bar, searching for “IAM,” and then clicking on “IAM.”
- In the left navigation pane, click on “Policies” and review the existing policies to ensure there are no unauthorized permissions.
- Identify the policy that grants suspicious access to data services. You can search for the policy name or review the policies attached to the user, group, or role associated with the suspicious access.
- Click on the policy name to open its details.
- Review the policy document to understand the permissions it grants. Look for any suspicious or unnecessary permissions related to data services.
- Click on “Edit policy” to modify the policy document.
- Remove any suspicious or unnecessary permissions by deleting the corresponding statements from the policy document. Be cautious while removing permissions to avoid disrupting legitimate access.
- After removing the unnecessary permissions, click on “Review policy” to validate the changes.
- Review the changes and ensure that the policy now only grants the required permissions for data services.
- Click on “Save changes” to apply the modified policy.
- Once the policy is saved, go back to the IAM dashboard by clicking on “Dashboard” in the left navigation pane.
- Review the users, groups, or roles associated with the suspicious access and ensure they have appropriate policies attached.
- If any users, groups, or roles have been granted excessive permissions, modify their policies accordingly by following the same steps mentioned above.
- Regularly monitor and review the IAM policies to ensure that only authorized and necessary permissions are granted to users, groups, and roles.
