A service interface of an SSL application hosted on at least one computer system in a hosted network selecting at least one authorized cipher suite. An SSL socket of the SSL application negotiating with another SSL socket of another SSL application in the hosted network for a mutual cipher from among the at least one authorized cipher suite and a shared key to encrypt information exchanged during a secure session. Responsive to establishing a security connection between the SSL socket and the another SSL socket using the selected mutual cipher, the service interface sends to a centralized service an identifier of the selected mutual cipher. Responsive to the service interface receiving a revoked cipher alert from the centralized service, the service interface revokes one or more sessions of the SSL application using a revoked cipher in the revoked cipher alert matching the selected mutual cipher.

Dynamically managing, from a centralized service, valid cipher suites allowed for secured sessions

At a centralized service in a hosted environment, a permission list is established of at least one cipher suite valid for secure connections across multiple network environments. Responsive to the centralized service receiving a request from a socket indicating the socket is negotiating a secure connection with another socket, the centralized service sends the permission list to the socket, wherein the socket negotiates for a mutual cipher suite specified in the permission list with the another socket. Responsive to the centralized service identifying that a particular cipher suite matching the mutual cipher suite used in an ongoing secure session for the socket is revoked, the centralized service notifies the socket that the mutual cipher suite is revoked.
