That's patently false. The longer the password, the better it will hold up against brute force attacks. Length and complexity also provide a measure of protection against those using rainbow tables.

Post-it notes on the monitor. Really though, it's all pretty straight forward. Minimum 6-8 characters, no maximum (try to encourage pass-phrases as they're
easier
to remember and harder to guess than simple words), complexity (combination of alphanumeric characters), 60 day expiration, 5-20 password history. No exceptions. None, at all. Nill. Nada. Zip. Most programs/systems there's not much you can do about the storage of the passwords in the system itself, but if you're talking about end-users then your biggest worry will be what I said in my
first
line. The best way to avoid this is probably to try to integrate as many systems as you can to use the same accounts. Right now we're working on getting all our in-house and supplier-built systems working off our Active Directory accounts
pulling
the passwords via Kerberos from our domain controllers. This however will also cause the issue of one system being compromised and they all get compromised. It's a risk/benefit write-off thing - we think the risk is worth it as the other option IS the dreaded post-it notes. -----Original Message----- From: Securi Net [mailto:securinet2004 () yahoo ca] Sent: Friday, 21 April 2006 2:44 AM To: security-basics () securityfocus com Subject: Password Management Hello list members, Does anyone know of any password management standards that are out there? I am looking at drafting an Enterprise wide strategy for managing passwords, which should encompass change, exceptions to change,
password
storage security, secure practices, categorization of accounts, etc. What I am trying to accomplish is to give a robust and resilient structure to all the best practices out there around password management. I don't expect to find a silver bullet, but would welcome any
feedback.
