This review looks at the similarities and differences between KSA���s cyber security policy framework with these three nations. The review will note some of the defining characteristics and approaches to cyber security in the smart cities of USA, India, and Singapore. After reviewing the current framework in Saudi Arabia, this paper will make suggestions such as updating Saudi���s cybercrime legislation like in the US or formulating a master cyber security plan as seen in Singapore that will improve KSA���s framework creating the best framework model for cyber security in its smart cities.
