Cross-Site Scripting (XSS)

Cross-Site Scripting, commonly known as XSS, is a persistent security vulnerability that plagues many websites. It occurs when an attacker manages to inject malicious code, usually in the form of a script, into a web application. This code is then executed by the browser of an unsuspecting user who visits the compromised page.

The risks posed by XSS include unauthorised access to a user's cookies, session tokens, or other sensitive information that can lead to identity theft. Additionally, attackers can potentially rewrite the content of the web page to gather personal details like credit card details from users, leading to financial fraud.

One common way to prevent XSS is by properly validating and sanitising all user input, ensuring that only safe and expected data is processed by the web application. Security practices should ensure that data is encoded so that the browser interprets it only as data, not executable code.

To mitigate the risks associated with XSS, it's critical to adopt a secure coding approach and perform regular security reviews and updates. Employing a web application firewall (WAF) can provide an extra layer of security against various forms of cyber threats, including XSS attacks.

Preventative Measures:
