Surprise for you. Aircraft have had computer systems for quite q while now. But they haven't been accessible to passengers up to now. With everything on the same network, anyone could hack into the control network from the passenger network. That's what is alarming in this case. It would have been much easier and safer to just install two physically independent networks. |

It would have been much easier and safer to just install two physically independent networks. To 'hack' into a system you have to have an input device like a keyboard. A touch screen that allows you to select a film channel, audio channel or Air phone is scarcely going to go any further than that ! I built networks. In one building the server ran an Office network, a Student network and our Tech network. We could see everything on the other networks. The students could only see their own network. The Office staff could only see their own network. It would appear that your knowledge of computers and IT is right up there with your knowledge of aviation ! |

One day recently I walked up to them and one clearly had a Microsoft BSOD. I didn't try to hack in, but someone might. Whether or not they are successful depends on how well the system was designed. I built networks. In one building the server ran an Office network, a Student network and our Tech network. We could see everything on the other networks. The students could only see their own network. The Office staff could only see their own network. Yes, such is quite common in the real world. It would appear that your knowledge of computers and IT is right up there with your knowledge of aviation ! Is that surprising? -- Jim Pennino Remove .spam.sux to reply. |

I recently saw a similar error displayed on a parking garage ticket dispenser. What input device would the would-be hacker use? Was there a touch-screen keyboard available? Some other input device accessible? "Someone might" try hacking *any* system. A computer's mere existence is enough of a challenge for some folks. Are you suggesting that the ATM should not be "connected" to another system because it represents a security vulnerability (which was the premise that started this thread)? -- John T http://sage1solutions.com/blogs/TknoFlyer http://sage1solutions.com/products NEW!

Some other input device accessible? There is also a keypad on those ATMS. Who knows what it's functionality is; one would hope none and neither the touch screen nor the keypad do anything until the system is reset from the inside, but as I didn't design the system, I can't say if that's how it works. "Someone might" try hacking *any* system. A computer's mere existence is enough of a challenge for some folks. Are you suggesting that the ATM should not be "connected" to another system because it represents a security vulnerability (which was the premise that started this thread)? Ummm, no. While physical separation of systems is one of the better deterents to hacking, it isn't the only method to prevent it. Systems that are interconnected can be designed to be secure. -- Jim Pennino Remove .spam.sux to reply. |

The Office staff could only see their own network. So you have hundreds of passenger devices on the network. Due to a bug, one or many may malfunction and cause a packet storm, either bringing down the network or causing unacceptable latency. High latency can cause autopilot oscillation and loss of control. Oops. You do NOT put noncritical devices on the same physical network as critical ones. You just don't. You don't even bridge them together, because problems on one side of the bridge might crash the bridge itself, affecting the critical network. |

High latency can cause autopilot oscillation and loss of control. Oops. We are talking about the flight systems of an aircraft with, as I suspect you're aware, two pilots who are there and are trained for such an eventuality. Autopilots falling over or going awry for a time are not unknown. As a bye most ISPs handle hundreds, thousands and sometimes hundreds of thousands of contacts per minute without falling over. 500 passengers wanting to watch the same movie isn't going to crash the system |
