Documentation

README

Excerpt

Ensure Lambda functions do not allow unknown cross account access via permission policies

Description

Ensure that all your Amazon Lambda functions are configured to allow access only to trusted AWS accounts in order to protect against unauthorized cross-account access.

Allowing unknown (unauthorized) AWS accounts to invoke your Amazon Lambda functions can lead to data exposure and data loss. To prevent any unauthorized invocation requests for your Lambda functions, restrict access only to trusted AWS accounts.

Impact

Restricting cross-account access may break existing integrations with partner or trusted accounts. Ensure all legitimate cross-account relationships are documented before restricting access.

Audit Procedure

Using AWS Console
