Security Settings in the Device
Siemens recommends applying the provided security updates by using the corresponding tooling and docu-
mented procedures that are available with the product. If supported by the product, an automatic means to
apply the security updates across multiple product instances can be used.
Siemens recommends validating any security update before being applied, and supervision by trained staff of
the update process in the target environment.
The most important security requirements are the following:
•
Authentication and authorization of the users
•
Assurance of the integrity of the transmitted data
•
Protections against virus, trojans, and other malware
•
Collection and saving of log files
•
Operation of the system in a protected environment (physical security)
•
Every user is given the only those rights that are necessary to fulfill the corresponding work
•
Assurance, that in case of a system failure, a restoration is possible without or only with marginal data
loss
•
Only activate required services and ports
•
Network load of critical systems are limited to the extent to make the systems continue to work under
maximum load. For example, limit the number of broadcasts in the power-system components.
The 7SR5 Security Manual serves as a recommendation for the secure commissioning and operations of the
7SR5 IEDs in networked environments.
During the complete product lifecycle, from commissioning to operation and maintenance, all service
personnel, project personnel, customers, and operators involved should consider the recommendations in this
manual.
