Let’s say an operating system is installed on a computer and a DBMS is installed on the same computer. Suppose that the operating system has a security vulnerability. Is there a possibility that the security vulnerability of the OS causes a security vulnerability of the DBMS?
Thanks.
absolutely. If a user can exploit an OS bug to get root access, they can do anything they want. Steal your database, mess around with things, etc…
That’s why its important to always get latest security updates for you servers. Also, its common practice to keep servers in a de-militarized zone, behind firewalls. Only the ports that need to be open should be open.
