Cross-Site Scripting (XSS) in Cybersecurity

XSS Definition:

Cross-Site Scripting (XSS) is a type of web vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. XSS cyber security protocol is necessary as these scripts can steal data, manipulate content, or redirect users to malicious sites.

Cross-Site Scripting (XSS) Use Cases:

  • Exploited in phishing campaigns to steal session cookies or sensitive data from users.
  • Used by attackers to deface websites or inject harmful content into web applications.

Related Terms:

  • Injection Attack
  • SQL Injection
  • Web Application Firewall (WAF)
  • Content Security Policy (CSP)

Questions and Answers:

  •  How do attackers exploit XSS vulnerabilities for XSS attacks?

    Attackers inject malicious code into web pages that execute when viewed by other users, often targeting session cookies or personal data with XSS attacks.

  • What are the different types of cross-site scripting (XSS)?

    The main types of cross-site scripting (XSS) are stored XSS (where the malicious script is stored on the server) and reflected XSS (where the script is reflected off a web server).

  • How can developers prevent attacks in XSS with cybersecurity best practices?

    Developers can prevent cross-site scripting (XSS) by validating and sanitizing user input, using secure coding practices, and implementing security headers like Content Security Policy (CSP).
