No its not.

This could be used for bypasses host based IDS for one thing, I think
thats pretty useful from an attackers point of view no? Theres quite a few
prodcuts that try and protect the NT kernel from modification by hooking
the SCM calls and NtSetSystemInformation(and \\device\physicalmemory of
course) so that you cant load a .sys file. Also this allows you to modify
the kernel without having a .sys file which is kinda cool.

Its more informative than the 'gayer than aids' thread anyway
