Too much faith in technology

from here and here

A networking failure shouldn't cause lights to get stuck in the ON position, and not anticipating those kinds of failures in your design is a pretty good indication that you didn't anticipate malicious misuse either. A good engineer anticipates failure. A good security engineer also anticipates malicious misuse. There are probably a number of security vulnerabilities in the system in addition to this lighting control DoS.
