Resource with over permissive DynamoDB GetItem permissions

Security & Compliance
No items found.

A resource with over permissive DynamoDB GetItem permissions refers to a situation where an AWS Identity and Access Management (IAM) user or role has been granted permissions to perform the GetItem action on a DynamoDB table without proper restrictions. The GetItem action allows users to retrieve a specific item from a DynamoDB table based on the item's primary key. If an IAM user or role has over permissive DynamoDB GetItem permissions, it means that they have access to read data from the table that they may not be authorized to view. This can lead to sensitive data being accessed or even exposed to unauthorized users, which can result in data breaches or other security incidents.


To address this issue, AWS users can take the following steps:

  1. Review the current IAM policies associated with the user or role to identify any policies that grant over permissive DynamoDB GetItem permissions.
  2. Update the IAM policies to restrict the permissions to only the necessary items and attributes, using conditions such as IP address range or specific DynamoDB table names.
  3. Use AWS tools like Amazon CloudWatch to monitor access to the DynamoDB table and investigate any suspicious activity.
  4. Consider implementing automated monitoring and alerts for any policy changes or unusual access patterns to the DynamoDB table.
  5. Regularly review and audit IAM policies to ensure that they remain up-to-date and in compliance with security best practices.

By ensuring that only authorized users have access to read data from DynamoDB tables, AWS users can reduce the risk of data breaches or unauthorized access to sensitive information.
