Cookies and JavaScript Security

 

Cookies are small pieces of data stored in the user’s browser by a website. They are used to store information like login sessions, preferences, and tracking data.

 

What are the limitations of cookies?

  • Limited storage size (~4KB per cookie)

  • Sent with every HTTP request (can affect performance)

  • Can be vulnerable to security risks like XSS and CSRF if not protected.

 

JavaScript security refers to the techniques and practices used to protect web applications from attacks that exploit JavaScript code running in the browser.

 

Key security risks include:

  • Cross-Site Scripting (XSS)
  • Cross-Site Request Forgery (CSRF)
  • Data exposure
  • Third-party script risks
