Military cyber defense

Cyber defense describes the military problem of defensive cybersecurity, in its entirety comprising technical, tactical, operational, and strategic/political options.

It is the most challenging task in the entire field of cybersecurity, as the military’s adversaries are by far the most sophisticated cyber attackers, capable of using a large variety of attack vectors with high expertise, combined with experience in military intelligence operations and electronic warfare. And it covers a vast range of complex technologies. From logistics, to command-and-control, to embedded systems in defense electronics and weapons systems, everything can be attacked and the potential consequences are among the most devastating.


New and high-standard security solutions need to be developed, but these first require the development of a market for cyber defense. Most suppliers are unfit to provide the knowhow and technologies required for this challenging field, making this a big and strategic task.


At DSI, we aim to help militaries in this quest. From strategy and doctrine development and implementation, through high security audits, to high assurance technology development, we cover all military cyber defense needs. We have longstanding expertise in this area: Our researchers have audited and assessed actual military cyber systems, including weapons systems; they have served as expert witnesses in military counterintelligence court cases; and, as project directors in NATO missions, they have developed and implemented entire national cyber defense strategies, technologies, laws, and operational structures.
