With much publicity the past several months focusing on hacking and
security breaches—in the media, TV shows, and movies—Garmin is setting the
record straight on the myths around one such possible breach: hacking
aircraft avionics.
Garmin, an industry leader in aviation avionics, said in a blog posted
June 17 that avionics manufacturers take numerous measures to ensure that
avionics are safe and secure for pilots to use.
Garmin said that its software runs on proprietary operating systems “that
would make it much more difficult to successfully accomplish an attack,”
and that “proprietary protocols, data input validations, and other
mitigations are in place to prevent viruses or malware from infecting, or
affecting, our equipment.”
In addition, avionics manufacturers perform safety assessments on what
could happen in an aircraft if the avionics data were corrupted,
deliberately or not, and then develop mitigations for those possibilities
before they go through equipment certification. And, all avionics are able
to be overridden by the pilot, if he or she determines the aircraft is not
doing what was intended. In many cases, pilots also must validate that
their flight plan information is uploaded correctly and accept it before
using it for active navigation. These actions help prevent input mistakes
by the pilot as well as enhance security.
