For devices where the medical device manufacturer intends to maintain remote access capability for service and updates, controls are needed to ensure this access does not compromise the security or operation of the device. There is one FDA recognized standard that addresses this for clinical laboratory devices, but many of the provisions could be instructive and appropriate for other types of devices.

This standard is entitled:
13-28 Remote Access to Clinical Laboratory Diagnostic Devices via the Internet CLSI AUTO9-A
CLSI is the CLinical and Laboratory Standards Institute.
