Restrict members in Hazelcast cluster

问题

I am working on a spring boot project where i am using Hazelcast as Cache. I have enabled tcp as join method and i also mentioned some members. The members are able to join. But the problem is other nodes are also able to join apart from the members. can anyone tell me how i can restrict it?

This is my configuration,

@Bean
    public Config hazelcastConfig() {
        Config config = new Config()
                .setClusterName("myCluster");
        List<String> members = new ArrayList<>();
        members.add("192.168.99.1:5523");
        members.add("192.168.99.2:5542");
        config.getNetworkConfig().getJoin()
                .setMulticastConfig(new MulticastConfig().setEnabled(false))
                .setTcpIpConfig(new TcpIpConfig().setEnabled(true).setMembers(members));
        config.getNetworkConfig().setPort(5523);
        return config;
    }

The main approach in the Hazelcast IMDG (community edition) is to configure the different cluster names.

You can also look into Hazelcast Enterprise which has a set of security features (JAAS authentication, TLS, symmetric encryption, ...).
