Sensitive data often invites threats.
Cross site scripting attacks are a type of cyber attack that can be very dangerous for businesses.
In this blog post, we will discuss what cross site scripting attacks are, and how you can protect your business from them.
What are Cross Site Scripting Attacks
Cross site scripting attacks (XSS) are a type of cyber attack in which the attacker injects malicious code into a web page. This code is then executed by the web browser, and can be used to steal sensitive information or perform other malicious actions.
Types of Cross Site Scripting Attacks
There are three main types of cross site scripting attacks: stored, reflected and DOM-based.
In a stored attack, the malicious code is injected into a web page and stored on the server. This means that anyone who visits the page will be infected with the code.
In a reflected attack, the code is injected into a web form field, such as a search box. When the user submits the form, the code is executed and can infect their computer.
DOM-based XSS is a type of XSS attack in which the attack payload is triggered by modifying the Document Object Model (DOM) in the browser of the target.
How Can You Protect Your Business from XSS attacks?
Cross site scripting attacks are difficult to detect, because they often look like legitimate code. However, there are some things that you can do to protect your business from these attacks.
Keep Your Software Up to Date
First, you should always keep your software up to date. This includes your web browser, operating system, and any plugins or extensions that you use. Outdated software often has security vulnerabilities that can be exploited by attackers.
Use a Web Application Firewall
Second, you should use a web application firewall (WAF). This will help to block malicious code from being injected into your web pages.
With WAF, one can customize the policies in order to meet the specific needs of your web page or application.
Content Security Policy
Thirdly, use a Content Security Policy (CSP). CSP is an extra level of security that can be used to prevent a website from allowing any in-line scripts.
It is one of the strongest methods available that can block XSS attacks completely.
