Re: Authorizing password changes in a health science center

At my former employer, a large financial institution, we handled it this
way.  We provided online password reset functionality via challenge
questions.  If someone could not answer the challenge question(s) we
required them to present their badge in person at the security
administration help desk.

This worked fine of course if the user happened to work at the home office.
If they worked at a remote location or were traveling  a responsible party,
usually a company officer, would send an email to security administration
who would then contact the individual via phone.  There are of course at
least a couple of ways this could go wrong, but we had plans to move to
digitally signed emails which would cover the biggest gap.

This process replaced the old give me the last 4 digits of your SSN way.

Hope this helps.

Subject: [SECURITY] Authorizing password changes in a health science center

The hospital has for a long time required a facsimile of the identification
badge each time a password change is requested.  It is a new century end
programs like Photoshop presented a new risk to that process.  We do not
want to ask for personal information on any email or phone call request.
(Our staff could be around others who might take advantage of that
information, if overheard)
We have added password challenge questions for half of our systems.  The
patient systems cannot be placed into a web page challenge at this time.
What do your account groups do to verify the identity of some one needing a
password change to systems with confidential information?
