How do I restrict access to user-defined functions in MySQL

问题

I am new to MySQL and I ran a Nessus scan on one my Servers and encountered a security finding which has a workaround to Restrict access to user-defined functions. Can someone help me please?

Update

The workaround is to Restrict access to create user-defined functions on the server

回答1:

This should work.

You can read more here http://dev.mysql.com/doc/refman/5.0/en/revoke.html

REVOKE EXECUTE ON FUNCTION mydb.myfunc FROM 'someuser'@'somehost';

However,

In my opinion it's better to grant certain users specific permissions rather making everything accessible and revoking perms from users. (It depends on the application)
