Implementing the ideal authentication strategy for your network could be tricky because while too much authentication would keep unauthorized network access under control, it could also prevent authorized network users from legitimately accessing network Read More

This FAQ answer is an excerpt from SNIPPETS by Bob Stout. Don't hold your breath.
