Operating System Choice for Critical Systems

It NEVER ceases to amaze me that when selecting an operating system for a critically important role, that people still chose Windows. Now this isnt a rant about how Linux or BSD are better or more secure than Microsoft Windows. I mean I think its quite an easy argument but one thing that is not up for debate is that Microsoft Windows is the most targeted operating system when it comes to Malware.

So why, for the love of all things good in the world, do you chose the most targeted OS for your critical systems. Here are just three recent incidents/reports that prompted this rant

  1. The investigation into the recent Spanish air crash noted that a critical ground system, that was designed to spot problems and alert people was actually switched off as it was infected with malware


  1. The latest worm currently doing the rounds and allegedly targeted at Irans Nuclear Reactor. Iran have admitted that some of their systems are indeed infected with this malware. Its a nuclear reactor for gawd sake.


  1. My favorite though was the recent announcement about an infection in a United States military network – their worst infaction ever, was caused by an infected USB drive.

That code spread undetected on both classified and unclassified systems, establishing what amounted to a digital beachhead, from which data could be transferred to servers under foreign control.


For gawd sake people, if its a critical system, dont chose the most malware targeted operating system. It makes no sense at all.
