Ports required generally across all types of clusters:Ģ2-23 - SSH access to the cluster resourcesĤ43 - Ambari, WebHCat REST API, HiveServer ODBC, and JDBCįor specific types of clusters and more details, review this article. For specific, well-defined applications like a three-tier app, this can be a highly secure deny-by-default. It provides private HTTP access to the cluster gateways.īased on your applications and enterprise segmentation strategy, restrict or allow traffic between internal resources based on your NSG rules. The endpoint will resolve to a private IP address inside the Virtual Network. All clusters deployed in a virtual network will also have a private endpoint. This configuration provides perimeter security. Only the allowed IP addresses in the inbound NSG rules can communicate with the Azure HDInsight cluster. An enterprise administrator can create a cluster inside a virtual network and use a network security group (NSG) to restrict access to the virtual network. Guidance: Perimeter security in Azure HDInsight is achieved through virtual networks. NS-1: Implement security for internal traffic Network Securityįor more information, see the Azure Security Benchmark: Network Security. To see how HDInsight completely maps to the Azure Security Benchmark, see the full HDInsight security baseline mapping file. Controls not applicable to HDInsight, and those for which the global guidance is recommended verbatim, have been excluded.
