System Security
There are three types of System/34 security: the badge reader that almost nobody ever bought, so it isn't discussed here; password security; and resource security.
Password security was used to begin a session at a computer terminal. Unless security was inactive, a correct password must be entered to begin.
The System/34 sign on looked like this:
- SIGN ON W1
- USER ID......... ________
- PASSWORD........ ____
- MENU (OPTIONAL). ______
- LIBRARY......... ________
The PROF ("Profile") procedure was used to work with User IDs and passwords. The user profile contains a 1-to-8 character alphanumeric User ID, a 4 character alphanumeric password, a code for the user's security rating—M (Master Security Officer), S (Security Officer), O (System Operator), C (Subconsole Operator), or D (Display Station Operator) -- and a number of other default settings.
The PRSRCID ("Profile Resource Security By User ID") procedure was used to establish security ratings for file and library objects. Access levels of O (Owner), G (Change), R (Read), E (Execute) or N (None) could be granted for a user to a particular resource.
The printed disk catalog (VTOC, Volume Table of Contents) displayed all secured objects with the notation 3 as being secured.

Famous quotes containing the words system and/or security:
“While the system of holding people in hostage is as old as the oldest war, a fresher note is introduced when a tyrannic state is at war with its own subjects and may hold any citizen in hostage with no law to restrain it.”
—Vladimir Nabokov (1899–1977)
“Thanks to recent trends in the theory of knowledge, history is now better aware of its own worth and unassailability than it formerly was. It is precisely in its inexact character, in the fact that it can never be normative and does not have to be, that its security lies.”
—Johan Huizinga (1872–1945)
