Donna,

The easy answer....

Provide VPN connection for your intranet to enable work processes... (email,
HIS etc.) and SHUT THE INTERNET OFF.  I have worked with several nursing
homes that find this solves many more problems than what they set out to
fix.

It almost sounds like Donna was speaking of outsourced IDS services
(managed IDS), and there probably are about 6 players in that space
right now (please correct me if I am wrong, Donna!!).  Managed IDS
services are great for organizations that have neither the
expertise/experience nor the human resources to implement and manage an
enterprise IDS capability - however, they are expensive.  I did some
research in this area a little over a year ago.  Fees varied a bit, but
(remember, this was 12+ months ago, so significant changes either way
could have taken place) I was looking at something like
$5000-$10000/month.  It's a lot of money, but compared to the cost to
staff up, train staff, purchase, implement, and monitor IDS(s) ongoing,
it's not even close.

The realm of "shrinkwrapped" IDS (i.e., non-managed service - you
install and monitor the system) is split into two categories:
host-based IDS and network-based.  Host-based IDS actively monitors a
single host (or, in some cases, a group of hosts) for intrusion.
Network-based systems monitor various parts of your network for
intrusion (depending on where you place them - you might have one on
your internet gateway(s) to monitor perimeter intrusion, or on different
segments of your network to monitor for intrusion on a particular
subnet).

IDS is just one of many security measures (like a firewall, anti-virus
systems, access control systems, etc.) that you may or may not choose to
apply based on your assessment of organizational risk.  So, no, HIPAA
doesn't require IDS per se - but neither does it require a whole bunch
of stuff, per se, that most organizations likely will implement.  It
requires that we assess the risk associated with housing, processing,
and transmitting PHI and apply controls commensurate with that risk.  I
expect that many healthcare organizations will, indeed, deploy intrusion
detection systems of some kind, but there will be vast numbers that do
not.  The one thing I can say very confidently about pretty much ALL IDS
products (even snort, which is a fantastic little program, as Keith
mentioned) is that they are absolutely useless without very skilled
technical staff to implement the system, and review and interpret the
logs and alerts coming from the system (emphasizing Keith's point).
These are not easy systems to deploy or manage effectively.  If you
determined that some level of IDS is required at your organization based
on assessed risk, then looking at a managed IDS solution would be a good
option in the absence of in-house technical talent.

For more information on IDS and how they are being used in various
industries, do a search on 'IDS' at whatis.com (a great sort of tech
encyclopedia).

Just about any security-conscious organization should already have one
in
place, to some degree.  However, "intrusion detection" is a loose term,
and
a very wide variety of products and services meet that description in
one
way or another.

If you're considering a network-based IDS, I'd recommend Snort.  It's
free,
updated often, and *very* widely used.  So your obvious cost is only
hardware.

However, in addition to the cost of the hardware to run the software,
you
also need to take into account whether you can afford someone who can
actually make sense of and respond to the data.  An IDS is no good
placed in
the hands of an admin who is only interested in keeping things going.
And a
security analyst can be expensive.  Bottom line: If you have some
bright
folks on staff, let them get going with something like Snort, and 1)
your
organization is going the extra mile, which will help with HIPAA, if
nothing
else (HIPAA doesn't care about IDS by definition), 2) your network and
staff
are improving daily.

But that's just my point of view!

Cheers

Keith
