2.3.2 Plant security
2.3.2.1 Physical protection of critical production areas
Unauthorized persons may be able to enter the production site/building and damage or alter
production equipment as a result of gaps in a company's physical security. Confidential
information can also be lost. This can be prevented if both the company's site and the
production areas are protected accordingly.
Company security
The company's physical security can be ensured via the following measures:
● Closed off and monitored company premises
● Entry control, keys / card readers and/or security personnel
● Escorting of external personnel by company employees
Physical production security
The physical security of a production location can also be ensured via the following measures:
● Separate access control for production areas.
● Installation of critical components in securely lockable cabinets / switching rooms
including monitoring and alarm signaling options
● Prohibited production areas with restricted access rights
● Configuration of the radio field to restrict the WLAN range so that it is not available outside
the defined areas (e.g. factory building).
● Guidelines that prevent the use of third-party data storage media (e.g. USB sticks) and IT
devices (e.g. notebooks) classified as insecure on the control.
