Security Considerations

Planning for security will help you identify security shortcomings and address them before you go into production.

MapR 6.0 and later releases provide security by default. If your cluster is not already secure, the MapR Converged Data Platform supports many different levels of security. For more information, see Getting Started with MapR Security.

Before installing MapR software using the published packages, make sure that you have reviewed the list of known vulnerabilities in Security Vulnerabilities. If a vulnerability applies to your release, contact your MapR support representative for a fix, and apply the fix immediately, if applicable.

If the cluster you are planning to install must communicate with other clusters, the clusters should have similar security attributes. Mixing secure and nonsecure clusters is not recommended. For more information, see Setting Up Cross-Cluster Security.
