Well put, Don. I'd add a couple of things.

1) Brute forcing these kinds of passwords can take eons to crack, thus
not worth the effort (the cracker would just move on to other

2) However, they can be discovered through any form of social
engineering (writing it down on the sticky note and leaving it for any
one to see; giving it to someone who you think is trusted -- the old
call from the "administrator" needing to update and test accounts,

3) passwords should also be a minimum of eight characters, and likely
can't exceed 15 depending on the O/S and it's restrictions. Don's
example illustrated the min 8 characters process, but I just wanted to
clearly state that.

Furthermore, users tend to shy away from these types of passwords
because of the difficulty of remembering them (hence it is easier to
use your kid's name, or favourite TV character).

Finally, there should be some sort of enforcement of password change
policy, say every six months, to make it truly effective (i.e., again
using SE, I could get the first four characters at one point, and then
the other four later on).
