Secure design principles, introduced by Saltzer and Schroeder in 1975, remain crucial for modern cybersecurity. These principles include Economy of Mechanism, Fail-safe Defaults, Complete Mediation, Open Design, Separation of Privilege, Least Privilege, Least Common Mechanism, and Psychological Acceptability. Additional principles are Work Factor and Compromise Recording. They emphasize simplicity, permission-based access, rigorous authority checks, transparency, multi-layered protection, minimal privileges, reduced sharing between users, usability, the cost of attacks, and thorough logging.
