Security principles
As instrument users may have varying skill levels, user access can be limited so that
certain functions such as editing SOPs, deleting records and editing results are
reserved for specific users only.
Administrators, users and permissions
One or more persons are set up as administrator . The administrator then controls
access to the instrument by defining User groups and Permissions :
„
A User group consists of one or more users that have the same access rights.
„
Permissions are the access rights that are allowed for each user group; these
range from the right to edit SOPs to the right to disable view selection.
The administrator:
„
Creates users – normally they assign each user a password, although this is not
mandatory. If passwords are not set up, the user just has to type their username
to log in, otherwise they must provide the password too.
„
Creates user groups.
„
Adds users to one or more user groups.
After installation
The first time the software is run the security system will be disabled and an
administrator user and administrators group will be created by the system. This is
so at least one user will have permission to configure the security system.
21 CFR Part 11
The security system can be upgraded to provide technical compliance with 21 CFR
Part 11 by installing a
feature key . Once this is installed, 21 CFR Part 11 security
settings can be applied and audit trails can be viewed. If the feature key is installed
the grey 21 CFR icon on the status bar becomes coloured.
This manual does not detail the 21 CFR Part 11 option but concentrates on the
standard security software.
