It's been there since Windows NT 4.0, and is used with mandatory integrity labels to enforce a mandatory integrity policy so that subjects with a lower integrity label cannot access (and, most importantly, cannot modify) objects with higher integrity labels.
It also exists separate from the Windows DAC ACL, which is what seems to govern user access to data files. One gets the impression it is intended to be used to protect DLL executables against modification by unauthorized processes, which is a worthy usage, but doesn't do anything for sensitivity- or privacy-based control of information flow. === Karen Mercedes Goertzel, CISSP, CSSLP Senior Lead Scientist Booz Allen Hamilton 703.698.7454 goertzel_ka...@bah.com "The hardest thing of all is to find a black cat in a dark room, especially if there is no cat." - Confucius ________________________________________ From: Gary McGraw [g...@cigital.com] Sent: 08 September 2015 15:44 To: Goertzel, Karen [USA]; Peter G.
