Today's focus: Reader: Where VoIP encryption is needed

By Steve Taylor and Larry Hettick

In continuing our discussion on encryption of VoIP, one reader
responded with an analysis of areas where he felt it was
important to encrypt VoIP traffic.

The reader pointed out that while he agreed in principle with
our premise that encryption was generally not necessary, he
pointed out some areas where he felt encryption was most
appropriate.

In particular, he noted:

"1. Any IP contact center VoIP traffic (public or private
sector), where confidential information may be disclosed during
the conversation (calling a bank, calling the Motor Vehicle
Office, County Treasurer, etc.); especially as 'inline'
click-to-talk proliferates (and I certainly accept encryption
with any form of secure VPN, whether Web-based/SSL, or IPSec).
This would be predominantly non-intranet-based customer-to-agent
traffic.

"2. Rich media or collaboration server sessions, where
triple-play services are used. For example - Cisco MeetingPlace
sessions, where IP-based Web, video and voice traffic are in the
session. Collaboration servers and services (such as WebEx or
Microsoft Live Meeting) are becoming extremely popular, more so
with the cost of travel skyrocketing. These are hosted services
typically, and ride the public Internet, in many instances.

"3. VoIP traffic in the first responder and public safety space
- whether wired or wireless. Whether pure VoIP, or LMR traffic
over IP, this should definitely be encrypted (common example -
cop car with IP phone, talking over a 802.11 hot spot, back to
substation, or metropolitan base station).

"4. College campuses, where VoIP - wired or wireless - VLANS,
and/or hot-spots carry sensitive information (student personal
data, exam scores, medical information, etc.).

"5. Healthcare where there is a HIPAA or confidentiality mandate
to secure VoIP traffic/data."

We think the fifth point is particularly relevant. Not only is
it important to be concerned about protecting information where
necessary, but it's also important to comply with regulations.
(And we'll wait for our readers to comment on whether mandated
encryption in certain situations is or is not appropriate.)
