Frequently Asked Questions

What is cybersecurity?

Cybersecurity is the practice of protecting systems, networks, and applications from digital attacks, unauthorized access, and data breaches. It encompasses a wide range of disciplines including network security, application security, authentication, encryption, and incident response. For web developers, cybersecurity means building applications that protect user data and resist common attack vectors.

What is zero trust architecture?

Zero trust architecture is a security model based on the principle of 'never trust, always verify.' Unlike traditional perimeter-based security, zero trust assumes that threats can come from both outside and inside the network. Every request is authenticated, authorized, and encrypted regardless of its origin, using techniques like micro-segmentation, identity-based access, and continuous verification.

What is the OWASP Top 10?

The OWASP Top 10 is a regularly updated list of the most critical web application security risks, published by the Open Web Application Security Project. It includes vulnerabilities like injection attacks, broken authentication, cross-site scripting (XSS), security misconfigurations, and server-side request forgery (SSRF). Understanding and mitigating these risks is essential for every web developer.

How do I start learning cybersecurity?

Start by understanding the fundamentals: the CIA triad (confidentiality, integrity, availability), common threat types, and defense-in-depth strategies. Then learn practical skills like secure authentication implementation, HTTPS/TLS, input validation, and security headers. Practice with tools like OWASP ZAP for vulnerability scanning and gradually move into advanced topics like penetration testing and DevSecOps.
