One of the principles of modern aviation design is to re-use standard components where possible, including in computers, networks, and so on.

The new Boeing 787 will offer ethernet connections to the passengers. How good is that ? Internet access for anybody. But FAA expressed a concern, because the 787 will also use ethernet for controls, navigation and maintenance networks, and this raises security questions…

The main issue is to know if a physical connection between passenger and airplane’s technical networks will exist or not. Because if this is the case the remote possibility of a passenger corrupting operational data or even taking control of the plane !

Even if the protocols used on both networks are different, as soon as a connection exists, the possibility of an attack do exist as well. wired published a very good paper about it, and the comments on it are also interesting.

Don’t think that applies only to airliners. The G1000 glass cockpit is also equipped with an ethernet connection. Not to offer in-flight entertainment, but for integration in simulators. As explained in my post about G1000 training tips, the FNPT-II with G1000 do include the actual unit, driven via its ethernet connection.

Ok, this do not allow to take control of the plane, but wrong navigational indication can have catastrophic consequences on a plane flying IFR in IMC… and remember that G1000 is also available on larger planes and even some jets.

To close this post with a touch of fun, here is a german comic…

If you don’t read german, the text is “New device detected: Airbus 310. Start automatic configuration assistant ?”…
