MySQL Enterprise Edition provides plugins that implement security features using external services:
MySQL Enterprise Edition includes an authentication plugin that enables MySQL Server to use PAM (Pluggable Authentication Modules) to authenticate MySQL users. PAM enables a system to use a standard interface to access various kinds of authentication methods, such as Unix passwords or an LDAP directory. For more information, see Section 22.214.171.124, “PAM Pluggable Authentication”.
MySQL Enterprise Edition includes an authentication plugin that performs external authentication on Windows, enabling MySQL Server to use native Windows services to authenticate client connections. Users who have logged in to Windows can connect from MySQL client programs to the server based on the information in their environment without specifying an additional password. For more information, see Section 126.96.36.199, “Windows Pluggable Authentication”.
MySQL Enterprise Edition includes a set of encryption functions based on the OpenSSL library that expose OpenSSL capabilities at the SQL level. These functions enable masking existing data using several methods such as obfuscation (removing identifying characteristics), generation of formatted random data, and data replacement or substitution. For more information, see Section 24.4, “MySQL Enterprise Encryption Overview”.
MySQL Enterprise Edition 5.7 and higher includes a keyring plugin that uses Oracle Key Vault as a back end for keyring storage. For more information, see The MySQL Keyring.
