Data Security Introduction
VA FileMan has facilities for screening access to
entire files
and to data within files on a
field-by-field basis. Access to previously defined
templates is also
controlled.
When used with Kernel, there are two possible mechanisms for control of
user access:
- By associating an Access Code with every user and with every file,
field, and template on the system. The user's Access Code is stored in the
local variable.
- Or, by doing a lookup into a user's entry in the NEW PERSON
file (#200) to see if the file in question is available to that user. (The
method is in effect only if Kernel's File Access Security has been installed on
the system. It takes precedence over the Access Code method for file-level
security. Field and template security are unaffected by Kernel's File Access
Security; they remain enforced by Access Code.)
These methods for data security are described in this chapter.
