A committee draft for vote has been circulated for the AAMI TIR 57 Principles for medical device information security risk management. The objective of this TIR is to provide guidance on how medical device manufacturers can manage risks from security threats that could impact the confidentiality, integrity, and/or availability of the device or the information processed by the device. Because medical device manufacturers are already familiar with ANSI/AAMI/ISO 14971:2007, this guidance follows the basic structure of that standard. AAMI has issued a draft for vote by participating members.
