You can configure the security protocols and cipher suites that are accepted by Connection Server. You can define a global acceptance policy that applies to all Connection Server instances in a replicated group, or you can define an acceptance policy for individual Connection Server instances and security servers.
You also can configure the security protocols and cipher suites that Connection Server instances propose when connecting to vCenter Server and View Composer. You can define a global proposal policy that applies to all Connection Server instances in a replicated group. You cannot define individual instances to opt out of a global proposal policy.
