In Homer's Iliad, Cassandra's warnings are ignored but later come true. In American folklore, Chicken Little warns that the sky is falling but it later proves false.
We've been getting a string of proclamations about the terrible state of smart grid security. Many of them come from security firms with a vested interest in scaring people. They remind me of similar warnings 15 years ago about Internet security, most of which never came true.
What about today's warnings. Do they come from Cassandras -- legitimate prophets who will be proven correct? Or are they Chicken Littles, needlessly worrying people?
