Physical network access protection

Protection from unauthorized access

Siemens developed the IE RJ45 port lock to protect open, unused RJ45 interfaces. It connects RJ45 ports mechanically to terminal devices or network components. As an additional measure, the IE RJ45 port lock can help to protect networks from unauthorized access, thereby enhancing the security of industrial production plants. A well-balanced, holistic security concept also includes physical protection measures. Open, unused RJ45 interfaces that can be used by unauthorized third parties to access networks are a well-known problem. In order to mitigate this risk, Siemens is now offering the IE RJ45 port lock which enables RJ45 ports to terminal devices and network components to be locked mechanically. The rugged design of the port lock in the form of a

plug means the plug snaps securely into place at the RJ45 interface, preventing the insertion of RJ45 cables. This port lock helps to prevent unwanted

use of empty RJ45 ports even on non-configurable network components. The integrated lock that can only be locked and unlocked using a mechanical key blocks the latch of the RJ45 port lock. A mechanical key is used to remove or unlock the port lock. Additional benefits include the sturdy design suitable

for industrial purposes and the ease of installation which, because of RJ45’s compatible design, does not require any additional tools.
