I have been asked this question by my college director while I was bunking the class.

The question is from Internal Security: Preventing Unauthorized Filesystem Access in chapter Access Control and Security of MySQL

Answer 1

The correct answer is (a) drwxrwxr-x

Explanation: Some database directories have the proper permissions like ‘drwx——‘ enables read, write, and execute access to the owner, but no access to anyone else. Other directories have an overly permissive access mode like ‘drwxrwxr-x’.
