RE: Secure Password Policy?

I would recommend, the longer the better. The more complex the better.
It is possible that their 8 characters recommendation is connected to
the weaker still used LM Hash passwords in Microsoft machines.

Windows by default creates LM Hashes out of passwords, unless disabled
(or the password is over 15 digits). 

A randomly generated password of 8 characters (this includes letter,
numbers and symbols) is pretty good. But bigger the better. Never used
dictionary words, and even backward dictionary words.
