  • Page 41: Security Features Of The 7Kn Powercenter 3000

    Security features of the 7KN POWERCENTER 3000. • Signed firmware: The 7KN Powercenter 3000 can only be operated with firmware signed by SIEMENS. This makes operation with corrupted or manipulated firmware impossible. Downgrading to firmware that may be faulty is not possible either.

  • Page 42: Further Recommended Security Measures

    4.7 Security features • Continuous vulnerability management: For 7KN Powercenter 3000 as for many other Siemens devices, continuous vulnerability management is set up. This means that if security vulnerabilities are found in individual program sections, they are published via Siemens ProductCERT and rectified as soon as possible in a firmware update.
  • Page 43 Installing, connecting, commissioning 4.7 Security features • VPN: VPN is the abbreviation for "virtual private network" and refers to a logically self- contained network. A VPN connects a few known network nodes via encrypted communication via a larger, potentially insecure network, e.g. Internet. If the web user interface of the 7KN Powercenter 3000 can be accessed via the Internet, we strongly recommend establishing a VPN connection between the web client (device on which the web browser is running) and the router.
