Solving AccessDeniedException in AWS CodeGuru Security

As developers, we strive to ensure the security and quality of our code. With AWS CodeGuru Security, Amazon Web Services (AWS) provides a powerful solution to automatically improve code quality and identify potential security vulnerabilities. However, when working with CodeGuru Security, you may come across an AccessDeniedException – a common error that can sometimes hinder your progress. In this article, we will dive into the details of this exception and explore ways to overcome it.

What is the AccessDeniedException?

The AccessDeniedException is an exception thrown by the com.amazonaws.services.codegurusecurity.model package of AWS CodeGuru Security. It indicates that the request you made to the CodeGuru Security service has been denied due to insufficient permissions.

This exception typically occurs when:

1. You do not have the necessary AWS Identity and Access Management (IAM) permissions to interact with the CodeGuru Security service.
2. Your IAM role does not have the required permissions to perform the specific CodeGuru Security operation.

Troubleshooting the AccessDeniedException

When encountering an AccessDeniedException, you can follow these steps to troubleshoot and resolve the issue:

Step 1: Check IAM permissions

The first thing you should do is verify that your IAM user or role has the necessary permissions to access the CodeGuru Security service. Ensure that the IAM policy attached to your user or role includes the required permissions by cross-checking it against the AWS CodeGuru Security IAM policy documentation.

Here’s an example IAM policy that grants the required permissions for CodeGuru Security:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "codeguru-security:*",
        "iam:PassRole"
      ],
      "Resource": "*"
    }
  ]
}

Ensure that this policy is attached to your IAM user or role.

Step 2: Verify IAM role trust relationship

If you are running CodeGuru Security from an EC2 instance or similar service, verify that the IAM role assigned to the instance has a trust relationship with CodeGuru Security. The trust relationship should include the following statement:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "codeguru.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}

If this statement is missing, modify your IAM role’s trust policy to include it.

Step 3: Validate AWS region settings

Ensure that the CodeGuru Security service is available in the AWS region you are working in. CodeGuru Security is currently available in the following regions:

• US East (N. Virginia)
• US East (Ohio)
• US West (Oregon)
• Europe (Ireland)
• Asia Pacific (Tokyo)

If you are using an alternate region, you may encounter the AccessDeniedException. Consider switching to one of the supported regions to resolve the issue.
