Then communications from products A and B will be authenticated but traffic from product C will be denied since there is no client certificate installed in product C to authenticate. Let's say a client certificate that authenticates the communication to the resource is installed in products A and B. In this scenario, communications from each product to the resource can be authenticated using mTLS. Let’s see how mTLS worksĬonsider there are 3 products product A, B, and C that communicates to a single resource. As a method of building trust between products and environments, mTLS can be used. There could be many security breaches and data exposure happens when communicating between these environments and across products. mTLS makes the client and server connections secure and trusted.įor example, cloud organizations have multiple products & multiple environments. All the users were informed to revoke using it in order to avoid compromising users' private information.Īs an alternative and a better approach, mTLS(Mutual Transport Layer Security) was introduced. ![]() The attacks such as POODLE made the security protocol SSL 3.0 not secure anymore. We used to do secure communication over the internet using the widely adopted methods as TLS: Transport Layer Security is formerly known for better version SSL 3.0.
