For those new to Linux Kernel Runtime Guard (LKRG), it is a kernel module that performs runtime integrity checking of the Linux kernel and detection of security vulnerability exploits against the kernel, developed primarily by Adam 'pi3' Zabrocki.
Adam gave this talk entitled "LKRG in a nutshell" at OSTconf, which was held online on August 10 to 13, 2020. (OSTconf was previously known as Linux Piter, held in St. Petersburg, Russia.)
This is effectively an update of "LKRG under the hood" that Adam had presented at CONFidence 2018. This new presentation reflects how LKRG has changed in the 2 years, and it is better focused for the audience (omitting some non-essential technical detail).
