The TLS protocol also offers the ability for the server to request that the client send an X.509 certificate to prove its identity. This is called mutual TLS (mTLS) as both parties are authenticated via certificates with TLS. Mutual TLS
Mutual TLS extends the client-server TLS model to include authentication of both parties. Where the bank relies on other, application-specific mechanisms to confirm a client’s identity — such as a user name and password
mTLS is fast, easy to use, and works everywhere. Nearly every language, server, database, client (and more!) already offers battle-tested TLS/SSL support. mTLS lets you replace countless fragile and frustrating bits of security infrastructure
It tells the client services whether to send encrypted traffic to the target service or to send plain-text requests. To enable a mutual TLS connection between services, you need to define a Policy object and a DestinationRule object. However in the Istio 1.4, a new automatic mutual TLS feature was added.
OAuth 2.0 Mutual TLS Client Authentication and Certificate Bound Access Tokens draft-ietf-oauth-mtls-07. Abstract. This document describes Transport Layer Security (TLS) mutual authentication using X.509 certificates as a mechanism for OAuth client authentication to the authorization sever as well as for certificate bound sender constrained access tokens as a

With the understanding of how TLS works lets now talk about mTLS. mTLS is an extension of TLS but whereas in TLS only the Server presents the certificate issued by a Certificate Authority (CA) in
Mutual TLS, or mTLS for short, is a method for mutual authentication. mTLS ensures that the parties at each end of a network connection are who they claim to be by verifying that they both have the correct private key. The information within their respective TLS certificates provides additional verification.
MTLS, or Mutual TLS (Transport Layer Security), is the successor to SSL and enables the server to authenticate the identify of the client. Learn how MTLS works! Mutual TLS enables the server to authenticate the identity of the client.
Mutual TLS authentication (mTLS) is much more widespread in business-to-business (B2B) applications, where a limited number of programmatic and homogeneous clients are connecting to specific web services, the operational burden is limited, and security requirements are usually much higher as compared to consumer environments.
Now you know TLS! See, it wasn’t that bad! Just one more small concept and you’ve got mTLS down! What is the “m” in “mTLS?” In the previous scenario, notice that while Alice was able to verify the identity of Bob, Bob was not able to verify her identity. Most of the time the server doesn’t care to verify the identity of the client
Mutual TLS (mTLS) In an ordinary TLS scenario, the server sends its certificate to the client, but the client never verifies itself. Mutual TLS is simply that the client verifies itself too. Why would we use mTLS? Well most probably for very secure clients we manually distribute certificates too, or for internal service-2-service communication
If the validation is successful, the trust would be mutual, hence Mutual TLS or mTLS. Mutual TLS and OAuth 2.0. Mutual TLS can be leveraged in different ways and by different types of systems. Let’s take a look at how OAuth 2.0 specifically makes use of this technology. RFC8705 is an OAuth 2.0 RFC that defines two main parts regarding the use
RFC 8705: Mutual TLS Client Authentication and Certificate-Bound Access Tokens (MTLS) MTLS is an extension of OAuth 2.0 that provides a mechanism of binding access tokens to a client certificate, one of many attempts at improving the security of Bearer Tokens by requiring the application using the token to authenticate itself.
Auto mTLS works by doing exactly that. If TLS settings are not explicitly configured in a DestinationRule, the sidecar will automatically determine if Istio mutual TLS should be sent. This means that without any configuration, all inter-mesh traffic will be mTLS encrypted. Gateways.
Mutual TLS authentication (mTLS) ensures that both the client and server in a session are presenting valid certificates to each other. Turning on mTLS will encrypt the xDS communication between Gloo Edge and Envoy and validate the identity of both parties in the session.
