Today, I was talking *techie* to a colleague in I.T. who still calls the IBMi Operating System - 'The AS/400'. *sigh*
We bumped over a few technology sleeping policemen during the conversation. Software is easy to upgrade. Mindsets are sometimes overlooked. This reminded me of the importance of keeping our skill sets current. If we don't move with the times, then our knowledge in our field of expertise quickly becomes out of date and hence 'of less worth'. I never want to be deprecated in favor of a new version of me. I want to make my own Nick Two Point Oh.
Anyway, the gray haired dusty shouldered gentleman in question was proudly proclaiming that the AS400 would be around forever because it was the most secure machine on the planet. Then proceeded to spout some un-verifiable (and almost certainly delusional) points about the AS400 still being used to power Google Servers, the president has one and its the only machine that has never ever had a virus.
Much as I like the IBMi operating system, this made me think "exactly what is it that defines a Virus?"
I'm sure I have written some virus-type code, playing tricks on coworkers, faking signon screens, remote controlling other peoples signons, etc. Does that count as an "as400" virus?
Anyway, Searching for some examples of old AS400 Security Holes, I came across the document (pasted below).
