FunctionShield Description
FunctionShield is a 100% free AWS Lambda security and Google Cloud Functions security library that equips developers with the ability to easily enforce strict security controls on serverless runtimes by addressing 4 common use cases: - Disable outbound internet connectivity (except for AWS/Google Cloud resources) from the serverless runtime environment, if such connections are not required - Disable read/write on the /tmp/ directory, if such operations are not required - Disable child process execution, if such execution is not required by the function - Disable read access to the function's handler and prevent source code leakage FunctionShield is no longer actively maintained and is recommended to be used as a reference only.
