5.8. System Segregation.
When operating the system, several security and operational
considerations should be taken into account:
Ensure that no similar equipment belonging to another company
can operate your system.
Limit unauthorized access between different departments of the
same company.
Allow a Service Provider to supply common services to several
companies.
Allow access to seal subgroups within a company.
5.8.1 Company Segregation by ORG_ID.
ORG_ID is a unique value assigned in production to each
customer. Every device supplied to that company is programmed
with the ORG_ID. All communication sessions are based on a
positive verification of the ORG_ID for complete match between
the devices. There is no way to modify the value of the ORG_ID
and only devices that comply with this request will get full service.
In the event a Reader tries to communicate with a seal without
appropriate ORG_ID and GLOBAL settings, the Illegal ORG_ID
flag in the LONG STATUS will be set. (For information regarding
the GLOBAL setting, see paragraph 5.7.3.).
5.8.2. Department Isolation.
The inter-department relationship works on a similar concept to
that described in section 5.7.1. It is possible to isolate equipment
between departments by using the DEPARTMENT parameter.
The default value of DEPARTMENT is zero. When set to default
settings, all the devices can communicate without any limitations.
