webMethods Broker fully supports the Secure Sockets Layer (SSL) protocol for exchanging information securely across a network. You can use SSL as part of your messaging solution for communications between JMS and C# messaging clients and webMethods Broker.

You can use SSL authentication for messaging clients in conjunction with Broker Access Control Lists (ACLs). With ACLs, you control access to Broker Servers, Brokers on those Broker Servers, client groups, territories, territory gateways, clusters, and cluster gateways. To gain access, a messaging client must have an identity (distinguished name and authenticator's distinguished name) that matches the ACLs.
