NAME
     amt — Abstract Machine Test Utility

SYNOPSIS
     amt [-m] [-p] [-q] [-s]

DESCRIPTION
     The amt utility is used to verify that the low level functions necessary
     to enforce requirements of the Controlled Access Protection Profile
     (CAPP) are working correctly.

     The amt utility must be executed with sufficient privileges and performs
     the following tests:

     Memory Read and Write
	     This test allocates between 5% to 10% of physical memory and
	     writes data to it, then reads the memory back to ensure the val‐
	     ues written remain unchanged.

     Memory Separation and Protection
	     This test ensures that user space programs cannot read and write
	     to areas of memory that is protected or is not shared.

     Privileged Instructions
	     This test ensures that the enforcement of the property that priv‐
	     ileged instructions should only be in supervisor mode is still in
	     effect.  The set of privileged instructions tested to confirm
	     this is architecture dependent.

     The options are as follows:

     -m	     Skip the memory test.

     -p	     Skip the privileged instructions test.

     -q	     Suppress the screen output.

     -s	     Skip the memory separation and protection test.

EXIT CODES
     <0	     An error occured in executing the tests.

     =0	     All the tests passed.

     >0	     The number of tests that failed or were skipped.

NOTES
     The overall result (pass or fail) is logged in the audit trail and system
     log.  The auditd(8) daemon must already be running for the results to be
     stored in the audit trail file.

     One of the above test may be skipped without getting a negative result.
     A test is skipped either with one of the above command-line options or
     automatically if there is not a test compatiable with the Target Of Eval‐
     uation (TOE). The audit administrator may want to perform the memory test
     only on startup since it can have large negative impact on the system
     performance.
