Web Security: Common Vulnerabilities And Their Mitigation

Video description

Coat your website with armor, protect yourself against the most common threats and vulnerabilities. Understand, with examples, how common security attacks work and how to mitigate them. Learn secure practices to keep your website users safe. Let's parse that. How do common security attacks work?: This course walks you through an entire range of web application security attacks, XSS, XSRF, Session Hijacking, Direct Object Reference and a whole lot more. How do we mitigate them?: Mitigating security risks is a web developer's core job. Learn by example how you can prevent script injection, use secure tokens to mitigate XSRF, manage sessions and cookies, sanitize and validate input, manage credentials safely using hashing and encryption etc. What secure practices to follow?: See what modern browsers have to offer for protection and risk mitigation, how you can limit the surface area you expose in your site.

What You Will Learn

  • Understand how common web security attacks work
  • Know how to write code which mitigates security risks
  • Implement secure coding practices to reduce vulnerabilities


The following audience will benefit from this course: - Students who have some experience in web programming and understand basic browser concepts, students who are beginners and have never done any web programming.
