How to be an Independent security researcher /Ethical Hacker

Explore the concept and misconceptions of common web vulnerabilities, including cross-site scripting and injection, and learn ethical defenses, decision processes, and client communication guidelines.

Explore cross-site scripting (xss) and its three main types—persistent (stored), non-persistent (reflected), and dom-based—along with how these client-side vulnerabilities arise, what they mean for browsers, and their impact on major sites.

Cross-site scripting attacks exploit injection in web applications by delivering malicious scripts to steal cookies and session data. Sanitize all data before rendering to prevent such scripts.

Sanitize input by applying filtering to neutralize harmful data and prevent parsing risks. Learn two approaches—encoding and escaping characters—and using standard sanitization functions for safe database, browser, and JavaScript contexts.

Stay motivated and determined to learn ethical hacking, practice on allowed sites, and solve problems to become a professional security researcher.
