Serverless framework configuration scanning |
20 |
Checkov supports the evaluation of policies on your Serverless framework files. When using checkov to scan a directory that contains a Serverless framework template it will validate if the file is compliant with AWS best practices such as having logging and auditing enabled, making sure S3 buckets are encrypted, HTTPS is being used, and more.
Full list of Serverless framework policies checks can be found here. The serverless scanning is utilizing checks that are part of the Cloudformation scanning implementation of checkov since Serverless resource definition extends the Cloudformation definition.
