Missing The Point

A security researcher used a modified cat6 cable and default creds on airline seat electronic boxes to compromise flight control systems on an aircraft. That’s really bad, and the FBI is investigating the crime. But why is it that no one seems to care that (1) SEB’s ride on the same network as flight control systems, (2) there’s a default password no one has bothered to change, and (3) no one on the aircraft was in any way bothered by some dude digging around under the seat and messing with cables?

Seriously – in the system design meetings for a million dollar aircraft, someone thought it would be a good idea to save, what, a grand by having a single open network for all electronic components on the aircraft?!

And I sincerely hope the WiFi networks they’re starting to put on the aircraft are on an isolated network that has nothing to do with any of the flight control equipment. It’s one thing to notice a guy plugging into some box under his seat … a guy using his computer mid-flight, nothing to see there.

On Snowden and Sharepoint

I’ve seen a number of articles focus on how the NSA failed to properly secure data within SharePoint, thus allowing Snowden to take off with a huge amount of sensitive data. What I haven’t seen anyone discuss is some type of AI that would analyze the SharePoint audit records against organisational information and what others in the same position access. Maybe the access would have gotten flagged to management and someone would have said “Oh, he’s doing this data migration to the Hawaiian cluster so I guess it’s reasonable he’d be accessing the data”. Maybe. Or they would have dug deeper and seen that something malicious was happening. Or, hell, maybe just talking to the guy about his suspicious access would have scared him enough that he’d have stopped. Who knows. But asking humans to read through the audit logs on a SharePoint server (the remediation suggestions that I’ve seen) is ‘find this needle in a stack of needles’ silly. Algorithms, and especially learning algorithms, are much better suited for that type of analysis.
