Bridging Security Infrastructure Between the Data Center and AWS Lambda

Last week I was able to present at Black Hat USA about infrastructure security work supporting Lambda. Abstract and slides are available here. The talk is partially based on two posts on the Square developer blog: Providing mTLS Identities to Lambdas and Expanding Secrets Infrastructure to AWS Lambda.

Using Lambda extensions to accelerate Secrets Manager access

AWS Lambdas have recently been extended with a new feature that adds a runtime environment before a Lambda is executed: Lambda extesions.

This work has also been covered in the AWS Compute Blog.
