Andrew posted a timely article on E2 about disabling Java and its effects on the enterprise.
"After news broke regarding the recent Java 7 zero-day exploits, several security experts went on record recommending that users disable Java completely.
While this sounds like an easy fix, it's not exactly a simple call to make for IT decision makers. After all, there are many organizations that have users who rely on Java applications to get things done.
Don't believe me? Try disabling Java and then attempt to join a WebEx meeting."
