Mechanism for enforcing access control at scale to an internet service using transport layer security (tls)

Abstract

Systems and methods are provided for a scalable load balancer to enable client certificate access control using mutual transport layer security authentication comprising hardware configured to receive trust store files including a certificate authority (CA) bundle and a certificate revocation list (CRL), generate a single trust store file based on the trust store files, distribute a snapshot of the single trust store file to one or more nodes of the scalable load balancer, verify, using the snapshot, a client certificate from a client device by searching for a trusted CA from the CA bundle in the snapshot, determine whether the CRL contained in the snapshot includes the client certificate, and upon verifying the client certificate and determining that the CRL does not contain the client certificate, transmit connection data from the client device to an application target.
