Security involves authentication and authorization. Linkerd leaves the task of authentication to third parties, such as TLS termination at Ingress, TLS origination at Egress, time-bound JSON Web Tokens (JWTs), and so on. Authorization can be implemented at the proxy level.

Automatic mTLS
The implementation of mTLS between microservices is out-of-the-box in Linkerd and doesn't need any special configuration. The Linkerd Identity component of the control plane acts as a PKI for signing certificates and renews them every 24 hours automatically.
