Re: [Trustedgrub-users] Is OS measured by Trusted Grub?

[Olga C. <ol...@gm...>]

TrustedGrub doesn't measure OS or apps after the boot process is over. If
you want the applications measured after the OS is launched, IMA (Integrity
Measurement Architecture) may be used for that. They have a wiki on
sourceforge. http://sourceforge.net/p/linux-ima/wiki/Home/
