That just takes care of one tool which can bring the system to its knees, limiting access to dd is a bandage. The issue is that any application on Linux can cause the system a great deal of stress or bring it down. (I do this a couple of times a year by accident.)
There are ways to protect against this kind of attack (accidental or not) such as setting resource limits on user accounts. Most distributions do not appear to ship with these in place by default, but if your system requires lots of uninterrupted uptime, the sysadmin should consider locking down resource usage.
