"Principles of Secure Software Design: Building Robust Applications"

Secure software design focuses on creating applications that are resistant to security threats from the start of the development process. It involves incorporating security principles such as least privilege, defense in depth, and fail-safe defaults. Key strategies include input validation, proper authentication, encryption, and secure error handling to prevent vulnerabilities like SQL injection, cross-site scripting (XSS), and buffer overflows. Additionally, secure software design emphasizes continuous testing, code reviews, and regular updates to address emerging threats. By prioritizing security from the outset, developers can build resilient applications that safeguard sensitive data and maintain user trust.
