Cyber security is becoming increasingly important in software and technology. Protecting user data, preventing unauthorized access and following secure development practices are essential for modern applications.

Authentication verifies who a user is, while authorization determines what that user is allowed to access. These concepts are related but have different responsibilities.

Password security is another critical topic. Passwords should never be stored as plain text. Strong hashing algorithms such as BCrypt help protect stored credentials.

SQL injection, XSS and CSRF are common risks in web applications. Using framework security features correctly, validating user input and protecting sensitive data are basic steps toward secure software.
