Cybersecurity is absolutely critical to any system facilitating communication between leaders of states with nuclear weapons. As offensive cyber actors, both nation state aligned and rogue, become more sophisticated with their attacks, and the means of attack become cheaper, national communication systems face high cyber risk.
The CATALINK team is acutely aware of these risks and built CATALINK with security at the center of the system. Because complexity is the enemy of security, CATALINK is radically simple. CATALINK users will know what every single line of code does, how every piece of hardware interacts, and where any bugs or vulnerabilities may lie.
As an additional form of security, with an eye toward the many supply chain exploits that have emerged in recent years, states will not only build their own CATALINK systems (based on design provided by the CATALINK team) but will also source all components and hardware for their systems. States will thus be able to source materials from suppliers that they trust.
