In the realm of cloud computing, serverless has emerged as a popular paradigm, offering a pay-as-you-go model and the ability to scale applications dynamically. However, with such flexibility comes the potential for security vulnerabilities. To address this need, sls-mentor, an open-source tool, has been developed to audit and improve the security of your AWS Serverless applications.

New Security Rules for Enhanced Protection

We are excited to announce the release of new security rules for sls-mentor to further enhance the security of your serverless applications. These rules cover IAM role policies, SQS queues, and RDS instances.

IAM Role Policies:

• No IAM Role Policy with wildcard Resource: Using wildcards in IAM role policies can grant excessive access to resources, making it easier for attackers to exploit. To mitigate this risk, we recommend using specific resources in IAM policies instead of wildcards.

SQS Queues:

• Encrypt your SQS queues: SQS queues store messages, making them potential targets for unauthorized access. To safeguard your message data, encrypt your SQS queues. SQS supports server-side encryption, ensuring that the data is encrypted on the server before it is stored in the queue.

RDS Instances:

• Encrypt your RDS instances: RDS databases manage sensitive data, and encrypting them is crucial for protecting this information. sls-mentor checks for unencrypted RDS instances and provides instructions on how to enable encryption.

Using sls-mentor to Enhance Security

In addition to the newly introduced security rules, sls-mentor already includes a comprehensive set of security checks that cover various aspects of AWS Serverless applications. These include checks for insecure IAM role permissions, vulnerable Lambda function configurations, and unencrypted CloudWatch logs. By leveraging these existing checks and the newly added ones, developers can thoroughly assess and strengthen the security posture of their serverless applications.

To utilize sls-mentor and benefit from its security enhancement capabilities, follow these simple steps:

1. Run sls-mentor: With your AWS credentials configured, run the following command to initiate the security analysis:

  npx sls-mentor@latest --report

1. Review the security report: The sls-mentor tool will generate a comprehensive report in your current directory, named .sls-mentor/index.html. This report provides insights into the security posture of your serverless applications, highlighting areas for improvement and offering actionable recommendations.
