We also have patch Garda's additional security as we know from one of the earlier lectures.
The patch card program is designed to prevent changes in the kernel system structure which are incompatible
with Microsoft assumptions.
The operation is based on the fact that when such a change is detected the system is immediately stopped.
However PESCHARDT does not protect against viruses root kits or changes to the disk.
The same occurs with kernel mode code signing it's additional protection that prevents loading unsighted
and drivers in the 64 bit version of the operating system.
All drivers must be signed However it is not security that can be bypassed.
It's not even designed as such but we've already mentioned this
newer versions of Windows particularly 64 bit versions in addition to security elements have a few built
in safeguards
even if the application does not use such safeguards.
We can configure it virtually using emet for it to use such safeguards.
The net result is that work in a 64 bit environment is inherently safer.
Thank you.
