File Groups; Passwords - VeriFone Vx810 Reference Manual

File Groups

The V
backed SRAM, and in non-volatile flash ROM memory. Files are assigned to one
of 15 groups for access control. Each group has a separate CONFIG.SYS file, and
each group is protected by a separate password. Groups are referred to as Group
n or GIDn throughout this manual.
The following rules apply to the V
•
The primary application must be downloaded onto Group 1.
•
On power up and after a restart, the device defaults to Group 1 as the
controlling group.
•
Group 1 applications have access to files stored in all other groups.
•
Applications stored in Groups 2 to 14 have access only to their own respective
files and to files stored in Group 15.
•
Group 15 is globally accessible, making it an ideal location for files shared by
multiple applications, such as shared libraries.
•
Groups 1–15 are empty until they are filled through a download.
For more information on managing file groups, refer to the Verix V Operating
System Programmers Manual, VPN 23230.

Passwords

Passwords for the V
compliance with PCI PED password requirements. These requirements include
the requiring of two passwords for sensitive operations; and, the requiring of all
passwords to be at least five characters in length.
Downloading and IPP Keyloading are considered sensitive operations that require
two passwords, the System Mode password, followed by the GID1 password. The
OS will require the user to enter the GID 1 password every time the user selects
these operations in System Mode, regardless of whether the operation has
already been previously selected in the current System Mode session. For
example, the DOWNLOAD operation will require a password each time it is
selected, even if the user performs a second DOWNLOAD operation immediately
after the first DOWNLOAD operation is completed and does not exit System
Mode.
The OS will require all passwords to be at least five characters and up to ten
characters in length for System Mode and all GIDs.
