If your sysadmin isn't looking at logs every day, then you have no
sysadmin. A very large component of that job involves log reading,
and on a daily basis. Logs are the pulse of any computer, but doubly
so for a server, and triply so for a server connected to the Internet.
Every job has a set of minimum functional requirements, and reading
logs definitely falls within those for the systems administrator.
 

That's why (competent, meaningful) systems administration is a
full-time job in and of itself. Anyone who disagrees probably hasn't
tried to do it. It might profit anyone who falls into this category to
spend some quality time looking around at

As to the "50-90" day password change policy, I'd suggest that, while
it's better than no policy at all, it's not much better. Any password
on an Internet-connected system longer than two weeks makes me
nervous, although enforcing truly well-chosen ones makes longer change
intervals more tolerable.

Cheers,
