Comparison of VoIP and TETRA Regarding Security in a Safety Critical Environment

In this document, University of Applied Sciences FH Technikum Wien (Vienna, Austria) analyze security threats on VoIP (Voice over IP) and TETRA (Terrestrial Trunked Radio) solutions and mitigation techniques.



“We recommend Tetra for safety critical environments like vessel and port terminal operations, Airports and government emergency authorities. Any place using Tetra should have a backup plan or plan B in case of unsolved attack or disaster. Backup could be using VOIP app, GSM (Global System for Mobile communications) with push to talk feature and many other applications can be used. VoIP can be used mainly in private communication with taking all security countermeasures into action to mitigate risks on Confidentiality, Integrity and Availability.”
