The world is quickly moving towards a future where autonomous vehicles and transportation systems will be the norm, while conventional forms of travel powered by standard fuels will become obsolete. These new changes however also come with a plenty of security and safety issues of their own, more specifically the possibility of cyber-attacks. Cyber-physical security is the protection of physical systems, such as autonomous vehicles and transportation systems. It involves the integration of cyber-security measures into the design and operation of these systems to protect them from any possible threats. This is a critical operation as it is a big part of ensuring the safety of these systems in a world that will soon heavily rely on these systems.
