Seems ITIL and other practices get ignored until companies have egg on their face. Should have been a non starter if they had safe guards in place. Well, at least that's my humble take on the situation, everyone makes mistakes but for a security company that's a lot.

I can remember when Windows was said to have had 5 "rings", 0-4, but all the outside vendors wanted their programs to run on ring 1 and not 2, 3 or 4.

 

I don't know what they do these days. 😄 

 

ADDED:  Maybe I remembered wrongly.  This page says Windows uses 4 rings and that ring 0 is the "kernel mode" and that ring 3 is "user mode".  Linux has the same arrangement.

 

It looks like programs running in user-mode (ring 3) must issue calls to processes in rings 1 and 2 for input-output of various types.  😄
