  1. Home
  2. Configuration

    Information about configuring DataStax Enterprise, including using virtual nodes; setting up security; storing and accessing data exclusively from memory; setting up distributed data replication from remote clusters; running multiple DataStax Enterprise nodes on a single host machine, and automating the movement of data across different types of storage media.

  3. DSE Advanced Security

    DataStax Enterprise includes advanced data protection for enterprise-grade databases including DSE Unified Authentication, object permissions, encryption, and data auditing. The DSE Unified Authenticator provides authentication using any combination of internal Cassandra password authentication, LDAP pass-through authentication, and Kerberos authentication.

          Protects sensitive at-rest data stored in configuration files and in database tables.

        • Encrypting sensitive property values

          Encrypting sensitive properties in the dse.yaml and cassandra.yaml configuration files.

        • Configuring encryption per table (TDE)

          Configure transparent data encryption (TDE) on a per table basis. You can configure encryption with or without compression.

        • Client-to-node encryption using SSL

          Client-to-node encryption protects data in flight from client machines to a database cluster using SSL. It establishes a secure channel between the client and the coordinator node.

        • Node-to-node encryption using SSL

          Node-to-node (internode) encryption protects data that is transferred between nodes in a cluster using SSL.

        • Setting up SSL for nodetool, dsetool, and dse advrep

          Using nodetool, dsetool, and dse advrep with SSL encryption.

        • Server certificates for SSL encryption

          All nodes require relevant SSL certificates. Steps to generate SSL certificates for client-to-node encryptions or node-to-node encryption.

        • Spark SSL encryption with SSL

          Communication between Spark clients and clusters as well as communication between Spark nodes can be encrypted using SSL.

        • DSE Search encryption

          DSE Search index encryption shares the setup with Cassandra SSTable encryption.

        • Encrypting using local encryption keys

          To encrypt data using encryption keys that are stored locally, use the dse command to create a system key for encryption.

        • Encrypting using off-server encryption keys

          Configure KMIP (Key Management Interoperability Protocol) encryption to use encryption keys that are stored on another server.

        • Rekeying existing data

          Create a new local encryption key, change the table key filename, and re-encrypt the SSTables using the new key.

        • Migrating encrypted tables from earlier versions

          Encrypted tables require specific actions to migrate to later versions of DataStax Enterprise.

      • DSE Unified Authentication

        Documentation on configuring and using multiple, and different, authentication schemes simultaneously on a DataStax Enterprise cluster.

      • Authenticating with internal Cassandra password authentication

        DSE Unified Authentication works with internal Cassandra password authentication.

      • RPCs over Cassandra native protocol

        Steps to configure RPC permissions for external clients.

      • LDAP authentication

        LDAP authentication support for external LDAP services.

      • Authenticating with Kerberos

        DataStax Enterprise authentication with Kerberos protocol uses tickets to prove identity for nodes that communicate over non-secure networks.

      • Using cqlsh with Kerberos/SSL

        Configuration steps to use cqlsh with Kerberos and SSL.

      • Configuring firewall ports

        If a firewall runs on the nodes in the Cassandra or DataStax Enterprise cluster, open up ports to allow communication between the nodes.
