This topic article explains how to configure a Vormetric resource set to securely allow MySQL startup scripts to access encrypted GuardPoints.
...
When Linux starts a service, Linux also runs a startup script. The startup script runs when the machine powers on or when a service manually starts. The startup script startup script typically runs tasks that relate to the starting, stopping, and restarting of a service.
For database services, the startup script startup script typically runs tasks that occur in folders that hold database files. With encrypted database files, you must allow the startup script the startup script to access the database folders. If not, the database will not start properly, and in some cases, interfere with the power-on process for the machine.
As part of the startup process, the operating system needs permission to view and change file/folder ownership and permissions. As a result, if you want to guard var/lib/mysql, you must create two rules in your policy.
...
The system needs to access the commonly guarded (encrypted) folders inside of /var/lib/mysql.
Access to GuardPoints
The resource is relative to the GuardPoint. In other words, if the GuardPoint is /var/lib/mysql, and you want to allow access to a particular file in that directory, you would only need to specify that specific file in your resource parameter.
For instance if the GuardPoint is /var/lib/mysql/, then your resource would only be mysql.sock.
