madjimmie Posted July 25 Posted July 25 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. 1 Quote
Leader RedBaird Posted July 25 Author Leader Posted July 25 (edited) 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. 😄 What Are Rings in Operating Systems? | Baeldung on Computer Science Edited July 25 by RedBaird ADDED lines Quote
