NAME
       amtu - Abstract Machine Test Utility (AMTU)

SYNOPSIS
       amtu [-dmsinph]

DESCRIPTION
       Abstract	 Machine Test Utility (AMTU) is an administrative utility that
       checks whether the underlying protection mechanisms of the hardware are
       being  enforced.	  These	 checks	 are  a	 requirement of the Controlled
       Access	  Protection	  Profile      (CAPP)	   FPT_AMT.1	  (see
       http://www.radium.ncsc.mil/tpep/library/protection_pro‐
       files/CAPP-1.d.pdf).

       AMTU executes the following tests:

       * Memory
	      Randomly writes to areas of memory, then reads the  memory  back
	      to ensure the values written remain unchanged.

       * Memory Separation
	      Ensures  that user space programs cannot read and write to areas
	      of memory utilized by items such as Video RAM and kernel code.

       * I/O Controller - Network
	      Verifies random data transmitted is also the data	 received  for
	      each  configured network device.	Checks only Ethernet and token
	      ring devices that are configured and up.	Does not  check	 async
	      devices.

       * I/O Controller - Disk
	      Verifies	random	data written to disks remains unchanged.  Only
	      IDE and SCI controllers that are associated  with	 mounted  file
	      systems  are  checked.   Disk controllers with read-only mounted
	      file systems are not checked.

       * Supervisor Mode Instructions
	      Ensures that the enforcement of  the  property  that  privileged
	      instructions  should  only  be  in  supervisor  mode is still in
	      effect.  The set of privileged instructions  tested  to  confirm
	      this is architecture dependent.
