Re: Cisco, haven't we learned anything? (technician reset)

Just as an offshoot discussion, what's the state-of-the-art for AAA services? We use an modified tacacs server for multi-factor authentication, and are moving towards a model that supports single-use/rapid expiration passwords, with strict control over when and how local/emergency authentication can be used.

I'd be interested in that discussion, on or offlist.

This is NOT a default password in the IOS.  The use of "cisco" as
the access and enable passwords is a common practice by users, but
it isn't bundled in the IOS.  I've heard it began in training
classes, where students were taught to use "cisco" as the
passwords.

Oh, and for those of you who think it mad leet to use "c1sc0" as
your access and enable passwords, the miscreants are on to that as
well.  ;)

We've seen large, massively peered and backbone routers owned
through this same technique.  We've even seen folks who have
switched to Juniper, yet continue to use "cisco" as the login and
password.  :(

The nice thing about cooking up blame is that there is always
enough to serve everyone.

Thanks,
Rob.
