(mTLS) stands for Mutual Transport Layer Security.
(mTLS) is a method for mutual authentication between two parties in a network connection. It means that both the client and the server have to prove their identities to each other by using TLS certificates and public/private key pairs. This way, they can ensure that they are communicating with the intended party and not an impostor.
mTLS is useful for securing sensitive data transmission, such as in Internet of Things (IoT) systems, where devices need to verify each other before exchanging information. mTLS can also help protect APIs from unauthorized access by requiring clients to present valid certificates.
The basic steps of mTLS are as follows:
• Client connects to server
• Server presents its TLS certificate
• Client verifies the server’s certificate
• Client presents its TLS certificate
• Server verifies the client’s certificate
• Server grants access
• Client and server exchange information over encrypted TLS connection
mTLS is different from regular TLS, where only the server has to present and prove its certificate, while the client does not. mTLS provides a higher level of security and trust than regular TLS
