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.
Restricting cross-account access may break existing integrations with partner or trusted accounts. Ensure all legitimate cross-account relationships are documented before restricting access.
AWS Lambda, click Functions.Function name click on the name of the function that you want to reviewPermissions.Resource-based policy statements section, click View policy documentaws lambda list-functionsaws lambda list-functions --output table --query "Functions[*].FunctionName"
This command will provide a table titled ListFunctions
Run aws lambda get-policy on the functions listed
aws lambda get-policy --function-name "name_of_function" --output text --query "Policy"
All Lambda function resource-based policies contain only Principal ARNs belonging to trusted and approved AWS accounts within the organization.

Lambda functions do not allow cross-account access by default. Cross-account access requires explicit configuration of resource-based policies.
