Encrypting Data Transmission Between the Controller and Agent Log in to the active management node as user omm.
Authentication Requests for calling an API can be authenticated using either of the following methods: AK/SK-based authentication: Requests are authenticated by encrypting the request body using an AK/SK pair. Token-based authentication: Requests are authenticated using a token.

Using the Encryption Tool of the Flume Client You can use the encryption tool provided by the Flume client to encrypt some parameter values in the configuration file. Install the Flume client. Log in to the Flume client node and go to the client installation directory, for example
to add the following configurations to the hive-site.xml file on the Spark client: <property> <name>hive.enforce.bucketing</name> <value>false</value> </property> <property> <name>hive.enforce.sorting</name> <value>false</value> </property> Spark does not support the feature of encrypting

Configuring Flink Authentication and Encryption Security Authentication Flink supports the following authentication modes: Kerberos authentication: It is used between the Flink Yarn client and Yarn ResourceManager, JobManager and ZooKeeper, JobManager and HDFS, TaskManager and HDFS
The current Kerberos server supports only the aes256-cts-hmac-sha1-96:normal and aes128-cts-hmac-sha1-96:normal encryption types for encrypting cross-domain users, and the encryption types cannot be changed.
Keys used for encrypting system disks are provided by Key Management Service (KMS) in Data Encryption Workshop (DEW). You do not need to build and maintain the key management infrastructure.
