  Security, INSTALL, and trusted applications? 
 The Question is:
 
What is a trusted application and how do I go about making an application
trusted.
 
 
 The Answer is:
 
  You declare an executable or sharable image to be "trusted" by using
  the INSTALL command (with /PROTECT or /PRIVILEGE), or by granting the
  image a subsystem identifier.
 
  You should only declare an image as trusted if if the image is truly
  known to be "trustworthy" -- installing an image with privileges can
  have unintended effects on system or site security, such as a file write
  operation normally performed within the image that might now be able to
  save a file in an unintended and otherwise protected system directory.
 
  Creating a "trustworthy" application is a difficult task, involving the
  study of the "Guide to OpenVMS System Security" manual, and likely also
  involving one or more peer reviews of the design and the code by several
  security-conscious programmers to confirm that the resulting image is
  "trustworthy".
