What are Lambda layers and how do they enhance security?

Lambda layers are a way to package and share code and dependencies in AWS Lambda. They enhance security by allowing you to manage permissions and access to shared libraries separately from your function code.

Can you explain how to implement security best practices with Lambda layers?

Sure! To implement security best practices, ensure that your layers have the least privilege permissions, use versioning to manage updates, and regularly audit the code in your layers for vulnerabilities.

What are some common security risks associated with Lambda layers?

Common risks include exposing sensitive data through misconfigured permissions, using outdated libraries with known vulnerabilities, and not properly managing layer versions.

How can I monitor the security of my Lambda layers?

You can monitor security by using AWS CloudTrail to track API calls, setting up alerts for unusual activity, and regularly reviewing IAM policies associated with your layers.
