Скачать или смотреть Cookies & Sessions Explained + Preventing Cookie Hijacking Attacks (Practical Guide)

In this video, we dive deep into the concepts of cookies and sessions, essential components for managing user authentication and data storage on websites. You’ll learn:

What Cookies Are: Cookies are small pieces of data stored on your browser by a website, enabling the website to remember your preferences, login status, and more. We'll discuss different types of cookies, such as session cookies (temporary) and persistent cookies (long-term).

Understanding Sessions: Sessions are server-side files used to store data about a user's interaction with a site. While cookies help identify users, sessions store the state of user interactions. This ensures smooth navigation between pages and persistent login status.

The Role of Cookies in Sessions: Cookies often store a session ID, allowing servers to link requests from the same user during their session. This ensures that users remain authenticated and maintain a continuous browsing experience.

Next, we move to the practical section, where we demonstrate the cookie hijacking attack (also known as session hijacking):

What is Cookie Hijacking? Cookie hijacking is a form of attack where a malicious user intercepts and steals another user’s session cookie, granting unauthorized access to that user’s account. This attack can happen via techniques like packet sniffing over unsecured networks, cross-site scripting (XSS), or man-in-the-middle attacks.

Practical Demo: Cookie Hijacking Attack: We’ll walk through how a basic cookie hijacking attack is executed. Using tools like Wireshark, we’ll show how attackers can intercept HTTP traffic over unencrypted networks, capturing cookies, and using them to access victim accounts.

Protection Against Cookie Hijacking: You’ll also learn about best practices to defend against such attacks. We’ll cover important security measures like:

Using HTTPS to encrypt communication between the server and client.
Setting Secure and HttpOnly flags on cookies to limit exposure.
Implementing Session Expiration to invalidate cookies after a certain time.
Using Multi-Factor Authentication (MFA) to add an extra layer of security.
By the end of this video, you’ll have a thorough understanding of how cookies and sessions work, how attackers exploit vulnerabilities through cookie hijacking, and how to secure your website or application from such threats.
