security-and-hardening

Security-first development requires treating external inputs as hostile and secrets as sacred. You implement threat modeling to identify trust boundaries and valuable assets before hardening web application code against vulnerabilities.

Validating external input requires treating all inputs as hostile and applying strict encoding standards. You must validate user input and handle file uploads safely to prevent vulnerabilities in web applications.

You audit dependencies for vulnerabilities using tools like npm audit to identify known security flaws. This dependency auditing ensures your web application remains hardened against vulnerable third-party packages.

Creating a threat model involves identifying trust boundaries and valuable assets before hardening code. This process maps potential attack vectors, ensuring security best practices are applied to protect web application vulnerabilities.

Security hardening practices apply to web applications by enforcing vulnerability prevention patterns. Regardless of the framework, you must validate external input, use secure headers, and adhere to security-focused coding standards to prevent attacks.
