With Hazelcast’s extensible, JAAS based security feature, you can:
- 
authenticate both cluster members and clients 
- 
and perform access control checks on client operations. Access control can be done according to endpoint principal and/or endpoint address. 
You can enable security declaratively or programmatically, as shown below.
<hazelcast>
    ...
    <security enabled="true">
    ...
    </security>
    ...
</hazelcast>hazelcast:
  security:
    enabled: true        Config cfg = new Config();
        SecurityConfig securityCfg = cfg.getSecurityConfig();
        securityCfg.setEnabled( true );Also, see the Setting License Key section for information about how to set your Hazelcast Enterprise license.
