Sensitive data can be encrypted and stored after you specify an encryption algorithm during table creation. Encrypted storage and access control of data are used to ensure user data security. HBase stores service data to the HDFS after compression.
Encrypted Transmission Flink uses the following three encrypted transmission modes: Encrypted transmission inside YARN: It is used between the Flink YARN client and YARN ResourceManager, as well as YARN ResourceManager and JobManager.

For details about how to set parameters in the properties.properties file, see the parameter list in the properties.properties file in the corresponding typical scenario Configuring a Non-Encrypted Flume Data Collection Task and Configuring an Encrypted Flume Data Collection Task.
Configuring Kafka Data Encryption During Transmission The channel between components is not encrypted by default. You can set the following parameters to enable security channel encryption.
The old key is not deleted, and it is used to decrypt data encrypted using the old key. After security information is modified, for example, a database user password is changed, the new password is encrypted using the new key.

Table 1 Parameters Parameter Description Default Value spark.authenticate Whether to enable Spark internal security authentication Security mode: true Normal mode: false spark.authenticate.enableSaslEncryption Whether to enable encrypted communication based on Simple Authentication
The value must be an encrypted password.
By default, the communication is not encrypted during the communication for the sake of cluster performance. Users who have demanding security requirements can use the method described in this section for encryption. This topic is available for MRS 3.x or later.
