To secure any communications from/to Management Center, you can configure it to communicate over TLS/SSL.

Management Center communicates over many channels. To encrypt data transmitted over those channels, using TLS/SSL, you can do the following.

The /health endpoint is always served over HTTP even if TLS/SSL is enabled. See the property.
  • Serve the Management Center UI over HTTPS by doing one of the following:

  • If your Hazelcast cluster uses TLS, configure Management Center with the necessary truststore information. You’ll need to configure the truststore, using a client configuration file. See Cluster Connections.

  • If you’re using Clustered JMX in Management Center, enable TLS/SSL. See Enabling TLS/SSL for Clustered JMX.

  • If you’re using LDAP authentication, make sure you use LDAPS or enable the Start TLS field. See LDAP Authentication.

  • If you’re using Active Directory authentication, make sure you use Java’s truststore related system properties. See Active Directory Authentication.

Excluding TLS/SSL Protocols

When you enable TLS on the Management Center, it will support any of the TLS/SSL protocols that the JVM supports, by default.

To exclude specific protocols, set the property to a comma separated list of protocols to be excluded. For example, to allow only TLSv1.2, use the following property when starting Management Center:,SSLv2Hello,TLSv1,TLSv1.1

After starting Management Center, you should see a line similar to the following in the logs:

2017-06-21 12:35:54.856:INFO:oejus.SslContextFactory:Enabled Protocols
[TLSv1.2] of [SSLv2Hello, SSLv3, TLSv1, TLSv1.1, TLSv1.2]

Including and Excluding Cipher Suites

When you configure TLS you also can provide which cipher suites Management Center can use for establishing TLS connection. You can include cipher suites with the property and exclude cipher suites with the property on startup. You can either use the exact cipher suite name or a regular expression. For example:^SSL_.*$^.*_(MD5|SHA|SHA1)$,^TLS_RSA_.*$,^.*_NULL_.*$
