In this chapter, we introduced three main areas for Hive security: authentication, authorization, and encryption. We covered the authentications in Metastore server and HiveServer2. Then, we talked about default, storage-based, and SQL standard-based authorization methods in HiveServer2. At the end of this chapter, we discussed the use of Hive UDF for encryption and decryption. After going through this chapter, we should clearly understand the different areas that will help us address Hive security.

In the next chapter, we'll talk about using Hive with other tools.
