ChemStation Plus Security Pack — User Management and Application Security
which should be enabled manu-
ally before leaving the PC unat-
tended, e.g. during a break or
shift change, and
• for enhanced security a time-
based automated lock of the
session for other periods of
short-term absence from the
PC.
The time-based session lock is
configured centrally through users
with administrative rights in the
ChemStore C/S database, and is
automatically applied on all con-
nected ChemStation Plus applica-
tions. The session lock allows to
lock each instrument session indi-
vidually, so users sharing comput-
ers with two or more instruments
connected to one computer can
operate with a clear and unique
user identification. The name of the
current user and the instrument
session are always shown in the
title bar. The instrument sessions
can be locked either
• privately, allowing only the user
who locked the session or an
administrator to unlock it, or
• non-privately allowing all users
with a valid user-ID in the data
base to unlock the session, for
example during shift changes
(figure 11). If a dialog is still
open the application will auto-
matically lock privately.

User management and
ChemStation Plus Security Pack
user access rights
Security Pack provides a fully inte-
grated user management that is
independent of the Windows oper-
ating system. The user management
covers both the ChemStation Plus
data acquisition and data analysis
tasks and the ChemStore C/S data-
base data review privileges. The
entire user administration itself is a
user-privilege granted to adminis-
trators in the ChemStore C/S data-
base. The ChemStation Plus
Security Pack includes a modified
ChemStation operator level allow-
ing operators to perform all impor-
tant acquisition and data analysis
tasks for daily operations. Table 12
shows the most important changes
in user privileges compared to the
standard ChemStation for data
acquisition. The ChemStation
Manager always has access to all
tasks within the ChemStation. A
detailed documentation of the data
review user privileges in the
ChemStore C/S database is in the
ChemStore C/S concept guide.
Application security
The Security Pack only allows
users with a given user-ID to log on
to the ChemStation Plus applica-
tion, as shown in figure 9. Users
need to be set up by the adminis-
trator to gain access. At initial
login, users must specify their ini-
tial password in order to keep it
unique to each user. Protecting the
application software from unautho-
rized access during operation is
possible with a separate session
lock (figure 11). This lock function
offers
• an interactive session lock
