Learn how maritime cybersecurity intersects with the International Regulations for Preventing Collisions at Sea (COLREGs) in this DEF CON 33 conference talk. Explore the fundamental nautical rules of the road that professional mariners memorize as part of their training and certifications, focusing on how these safety protocols create predictable behaviors and shared responsibilities between vessels. Discover why the memorable guideline "Don't Turn To Port" carries special significance for cybersecurity professionals and how understanding maritime norms can mean the difference between effective and ineffective cyber operations. Examine existing research on cyber-physical system manipulation of rudder angle controllers in both manned and unmanned maritime systems, and understand threats specific to maritime choke points. Analyze why cyber manipulation inducing a port turn poses greater risks than starboard manipulation, regardless of location. Gain insights into how maritime rules influence legal liability for collisions at sea, and receive encouragement to deepen understanding of maritime profession fundamentals for enhanced cybersecurity effectiveness in nautical environments.
