This sounds like a good issue to raise at CTSC and/or UCIST.
There are many scenarios where I believe it's OK to just send back a
failed drive (unencrypted) for warranty.
- A disk for a server hosting public information.
- A managed workstation where user data is stored on central storage.
- A disk containing research information where the information is not
"Restricted". In this case, you can explain the risks to the researcher
and let the researcher decide, since it's their data.
For workstations/laptops containing Restricted information - those need to
be encrypted. The recent UVic experience has taught us that.
The tricky scenario, in my view, is shared storage that is typically
"enterprise" grade. Storage in secure server rooms containing data of
mixed security classifications. I think there needs to be some kind of
risk analysis there that needs to be considered and evaluated by
