Aside from frisking every user that walks into and out of the nortel campuses <honeywell used to do this at the corp HQ in MN, and they lost alot of proprietary info anyways>, what would you suggest that would mitigate the issues that non-perm contrators and sigruntled soon-to-be-non employees and those just stealing corp resources outright to fund their private enterprises might work in this setting? Experinces has taught me that unless one can keep someone out of something they should not have a finger or eyeball into; asking, telling, demanding they not look/peak/grab etc is useless at best, and like telling a child not to stick beans up their nose and then making sure the DR's emergency number is posted on the fridg and each bathroom mirror in the home as well as on each phone. I'm not saying stregthening passwords is totally a waste of time, as long as the encrypted hashes are not in plain sight, and with systems that lack a shadow password system, and when TCB is a burden best avoided, then strong passwords and all the efforts and time invested in trying to keep them so might be an effort of some waste. Of course, like most HUGE corporations, nortel was and is a beast unto itself, and often in such settings fingers on the same hand have problems knowing what the other fingers are doing let alone trying to track the other hand.

You need some user behavior/rules of engagement policies to deal with users bringing home password files and cracking them. And they should be enforced.

If you have 10 workstations and 1 server, it might be fine to have no network directory, but with 300,000 users, I would say it's impossible. I would consider: LDAP, NDS, AD, SecureID, RADIUS, TACACS. (notice the conspicuous absence of NIS, and I wanted to leave out AD, but it seems to be unavoidable these days.HP made this usless, unless they have finally enabled a shadow setup in new versions of the OS. We played the single sing-on game at nortel, and played with password cracking and all that, but, since 80% of the servers were hp's and they lacked any seperation of passwords from the required /etc/passwd file, users wanting to up their privs on a system just took copies of the /etc/passwd file home and cracked to the point they felt they needed. And our CISSP's spent alot of time putting together all these metrics on strong passwords and how effective they were making security of the network, without facing the reality of the 80% exposure faced. HP folks a few years ago hinted that HP was going to change theit OS to include shadow password implimentations, but, I've long since moved on and these days don;t have to play on much but SUN's and AIX systems, so I do not know if they have something beside the horrid TCB that would break most interal apps for companies and require alot of retrofitting.
