How does HBase ensure the security and authorization control of data?

HBase ensures the security and permission control of data through the following methods:

1. Authentication: HBase can verify a user’s identity through methods like Kerberos, ensuring that only authenticated users can access the data.
2. Authorization Control: HBase provides authorization control based on ACL (Access Control List) mechanisms, allowing different permissions to be set for each table or column family, such as read, write, and manage permissions, ensuring that users can only perform operations that they are authorized to do.
3. Data encryption: HBase supports TLS/SSL encryption to ensure the security of data during transmission, preventing data theft or tampering.
4. Security auditing: HBase is able to log user activities on data and support auditing functions, allowing administrators to track user actions through audit logs to ensure the security of data access.
5. Authorization management: HBase includes authorization management functionality, allowing users to restrict access to data through access control policies to ensure data security.

Using the above methods, HBase can effectively ensure the security of data and control permissions, protecting data from unauthorized access or modification.
