Configuring OpsCenter
OpsCenter Security
OpsCenter Security
Security configuration options and instructions.
Configuring SSL/TLS between OpsCenter and the DataStax Agents
OpsCenter uses Secure Socket Layer (SSL) to encrypt the communication protocol and authenticate traffic between DataStax agents and the main OpsCenter daemon. SSL is disabled by default. Enabling SSL is strongly recommended.
Connect to DSE with client-to-node encryption in OpsCenter and the DataStax Agents
Instructions for setting up OpsCenter and the DataStax Agents for connecting to DSE when client-to-node encryption is enabled.
Enabling HTTPS for the OpsCenter server
Enable Hypertext Transfer Protocol Secure (HTTPS) support in OpsCenter and specify SSL information for better security.
Configuring OpsCenter for Kerberos authentication
OpsCenter can use Kerberos to authenticate to DataStax Enterprise clusters. If a DataStax Enterprise cluster uses Kerberos authentication, you need to create and configure the OpsCenter principals before adding the cluster to OpsCenter.
Editing OpsCenter cluster connections for authentication or encryption
Cluster connections settings define how OpsCenter connects to a cluster. Edit the settings if authentication or encryption has been enabled on a cluster.
Configuring role-based security
OpsCenter allows enabling user authentication, adding users, and defining custom roles.
Authenticating OpsCenter users with LDAP
OpsCenter supports LDAP authentication support for external LDAP services.
Encrypting sensitive configuration values
Configuration encryption provides privacy and increased security for sensitive configuration values such as passwords.
Configuring security logging
Configure comprehensive security logging in logback.xml that records user activity within OpsCenter.
