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

A computer system comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable storage devices, and program instructions, stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, the stored program instructions comprising:
• program instructions to select, by a service interface of an SSL application hosted on at least one computer system in a hosted network, at least one authorized cipher suite;
• program instructions to negotiate, by an SSL socket of the SSL application 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;
• program instructions to, responsive to establishing a security connection between the SSL socket and the another SSL socket using the selected mutual cipher, send, by the service interface to a centralized service an identifier of the selected mutual cipher;
• and
• program instructions to, responsive to receiving, by the service interface, a revoked cipher alert from the centralized service, to revoke one or more sessions of the SSL application using a revoked cipher in the revoked cipher alert matching the selected mutual cipher.

A computer program product comprising one or more computer-readable storage devices and program instructions, stored on at least one of the one or more storage devices, the stored program instructions comprising:

• program instructions to select, by a service interface of an SSL application hosted on at least one computer system in a hosted network, at least one authorized cipher suite;
• program instructions to negotiate, by an SSL socket of the SSL application 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;
• program instructions to, responsive to establishing a security connection between the SSL socket and the another SSL socket using the selected mutual cipher, send, by the service interface to a centralized service an identifier of the selected mutual cipher;
• and
• program instructions to, responsive to receiving, by the service interface, a revoked cipher alert from the centralized service, to revoke one or more sessions of the SSL application using a revoked cipher in the revoked cipher alert matching the selected mutual cipher.
