Authentication Manager Integration Services, AMIS v. 1.x aka AM Prime
RSA SecurID Authentication Manager Server v. 8.x
Mutual authentication or two-way authentication (not to be confused with two-factor authentication) refers to two parties authenticating each other at the same time in an authentication protocol.
By default the TLS protocol only proves the identity of the server to the client using X.509 certificates, and the authentication of the client to the server is left to the application layer. TLS also offers client-to-server authentication using client-side X.509 authentication. As it requires provisioning of the certificates to the clients and involves less user-friendly experience, it's rarely used in end-user applications.https://en.wikipedia.org/wiki/Mutual_authentication#mTLS
MTLS in Prime is not a "standard" configuration, Tomcat natively supports MTLS, and we have several customers running with this configuration in production. The good news is RSA supports this configuration.
