FAA: Boeing's New 787 May Be Vulnerable to Hacker Attack
By Kim Zetter

Boeing's new 787 Dreamliner passenger jet may have a serious security vulnerability in its onboard computer networks that could allow passengers to access the plane's control systems, according to the U.S. Federal Aviation Administration.

The computer network in the Dreamliner's passenger compartment, designed to give passengers in-flight internet access, is connected to the plane's control, navigation and communication systems, an FAA report reveals.

The revelation is causing concern in security circles because the physical connection of the networks makes the plane's control systems vulnerable to hackers. A more secure design would physically separate the two computer networks. Boeing said it's aware of the issue and has designed a solution it will test shortly.

"This is serious," said Mark Loveless, a network security analyst with Autonomic Networks, a company in stealth mode, who presented a conference talk last year on Hacking the Friendly Skies (PowerPoint). "This isnít a desktop computer. It's controlling the systems that are keeping people from plunging to their deaths. So I hope they are really thinking about how to get this right."

Currently in the final stages of production, the 787 Dreamliner is Boeing's new mid-sized jet, which will seat between 210 and 330 passengers, depending on configuration.

Boeing says it has taken more than 800 advance orders for the new plane, which is due to enter service in November 2008. But the FAA is requiring Boeing to demonstrate that it has addressed the computer-network issue before the planes begin service.

According to the FAA document published in the Federal Register (mirrored at Cryptome.org), the vulnerability exists because the plane's computer systems connect the passenger network with the flight-safety, control and navigation network. It also connects to the airline's business and administrative-support network, which communicates maintenance issues to ground crews.

The design "allows new kinds of passenger connectivity to previously isolated data networks connected to systems that perform functions required for the safe operation of the airplane," says the FAA document. "Because of this new passenger connectivity, the proposed data-network design and integration may result in security vulnerabilities from intentional or unintentional corruption of data and systems critical to the safety and maintenance of the airplane."

The information is published in a "special conditions" document that the FAA produces when it encounters new aircraft designs and technologies that aren't addressed by existing regulations and standards.

An FAA spokesman said he would not be able to comment on the issue until next week.

Boeing spokeswoman Lori Gunter said the wording of the FAA document is misleading, and that the plane's networks don't completely connect.

Gunter wouldn't go into detail about how Boeing is tackling the issue but says it is employing a combination of solutions that involves some physical separation of the networks, known as "air gaps," and software firewalls. Gunter also mentioned other technical solutions, which she said are proprietary and didn't want to discuss in public.

"There are places where the networks are not touching, and there are places where they are," she said.

Gunter added that although data can pass between the networks, "there are protections in place" to ensure that the passenger internet service doesn't access the maintenance data or the navigation system "under any circumstance."

She said the safeguards protect the critical networks from unauthorized access, but the company still needs to conduct lab and in-flight testing to ensure that they work. This will occur in March when the first Dreamliner is ready for a test flight.

Gunter said Boeing has been working on the issue with the FAA for a number of years already and was aware that the agency was planning to publish a "special conditions" document regarding the Dreamliner.

Gunter said the FAA and Boeing have already agreed on the tests that the plane manufacturer will have to do to demonstrate that it has addressed the FAA's security concerns.

"It will all be done before the first airplane is delivered," she said.

Loveless said he's glad the FAA and Boeing are addressing the issue, but without knowing specifically what Boeing is doing, it is impossible to say whether the proposed solution will work as intended. Loveless said software firewalls offer some protection, but are not bulletproof, and he noted that the FAA has previously overlooked serious onboard-security issues.

"The fact that they are not sharing information about it is a concern," he said. "I'd be happier if a credible auditing firm took a look at it."

Special conditions are not unusual. The FAA publishes them whenever it encounters unusual issues regarding a plane's design or performance in order to communicate on record that it expects the manufacturer to address the issue. It's then up to the manufacturer to demonstrate to the FAA that it has solved the problem. Gunter said the FAA has issued eight special conditions on the Boeing 787, but that not all of them pertain to the plane's computer systems.

This is exactly what I mean when I say that there is an over-reliance on electrons in today's certified aircraft.  Whoever thought it would be possible to hijack a friggin' airliner from the passenger cabin, or (heaven forbid), from over the internet for crying out loud!  It will be possible now, thanks to Boeing not putting in two separate systems on the 787.

That was exactly my thought and it didn't make any sense.. All the fly-by-wire systems I've heard (not many I admit and most military grade) have at least 2 or 3 independent flight computers.

Reading a little more carefully:

So, it's not one system, but the problem still stands: The only unhackable system is one that can't be interfaced.

I believe it's media hype anyway at this point, but it's for the best, now they have to find a way to fix it :)

This is precisely the problem.  I do not believe it is hype.  I believe it is a legitimate concern.

I just cant imagine Boeing let FBW accessed from "outside". Urban legend in my opinion.

The control systems access the network to send and receive data with ground maintenance sources.  The idea is to be like the ACARS system found in most airliners today, except in this case it's apparently fed directly from the computers instead of just from sensors and uses the internet instead of other methods.  Another question here is whether allowing any ground communication with the flight deck computers might compromise system integrity.
