Fundamental Security Concepts for Developers

Every developer should understand the principle of least privilege, which emphasizes granting users only the permissions necessary to perform their tasks. This concept helps minimize potential vulnerabilities in systems by restricting access for users and services, thereby reducing the attack surface. Usable security is another critical aspect, which ensures that security mechanisms are user-friendly and engaging, encouraging adherence rather than evasion by users. When security features are designed with the user experience in mind, developers can achieve more effective compliance and create secure applications.
