LIOS Technologies Ensures Cyber Security of Distributed Temperature Sensing Systems

LIOS Technologies has revealed that it has introduced cyber security features into its Distributed Temperature Sensing (DTS) systems due to the frequently occurring security breaches. DTS systems were initially stand-alone but have now been integrated into Supervisory Control and Data Acquisition (SCADA) systems.

Special attention has been given to the structure of the DTS system interface due to the risks involved in cyber space. The system is built using a LIOS OTS controller that is based on a Digital Signal Processor, which performs data acquisition and data reduction.

The OTS controller has a built-in firewall to prevent intruder access. Optional encryption is also provided by the controller using the standard Transport Layer Security (TLS, RFC 5246) protocol. The OTS controller and the connecting system can be configured using TLS to provide a cryptographic certificate. The connection is rejected if security checks fail.

The software has been tested by the Association of German asset insurers (VdS). The software has also been exhaustively tested for security issues with standard security tools such as Netwox and Nessus. All these aspects together make the DTS system highly secure.
