Cybersecurity
may be discovered in OTS (off-the-shelf)
software and new problems are found
on an ongoing basis. Being able to react
to new software issues by securely updating
the device is an essential part of a
manufacturer's response in today's
threat landscape.
Securing Your Device's Data
Doesn't End with the Device Itself
Beyond protecting your device, it is
likely you will also need cloud connectivity.
Moving customer PHI from the
device to the cloud (and back) must be
secured. Thankfully, cloud providers like
AWS provide out-of-the-box services for
supporting IoMT connectivity and associated
downstream uses of that data.7
After a connection is established
between the device and the cloud, data
can be routed from an IoT broker to various
services like a database, long-term
storage for audits, and functions to route
data to external systems. Security must be
maintained every step of the way, and
cloud providers take this responsibility
seriously.8 (For more on protecting
cloud data, read the ICS four-part series,
Securing the Cloud with AWS.9
The Takeaway
AWS's shared responsibility model dictates
that the customer is responsible for
" security in the cloud " while AWS is
charged with " security of the cloud. "
Taking an end-to-end view - locking
down everything and ensuring data is
encrypted while at rest and in transit -
is essential for preventing cyber threat
actors from accessing networks and
devices to execute costly attacks.
