Cross Site Scripting

What Is Cross Site Scripting And How Do We Prevent It?

Cross site scripting attack involves the attackers imposing a threat after entering through a vulnerability gap. Such vulnerability gaps are left open due to irresponsive measures taken by the organization’s cybersecurity team. Attackers are always on the hunt for users using apps that are not secured enough and possess vulnerability within them. Such interaction of any user with a vulnerable application can be hazardous.

Cross site scripting attack allows an attacker to act as a user. This false representation of the attacker enables him to receive all other user privileges. Thus, they can cause threats to the actual users after breaching their data. This way, an attacker can gain full access to the desired sensitive data. These attacks also involve the creation of malicious links and proceeding to get the users’ clicks on such links. Later on, such clicks can turn into massive risks for business owners.

Example Of Cross Site Scripting Attack

An example of cross site scripting (XSS attack) may include a scenario where an attacker maintains corrupted or malicious files on a website’s search bar or contact forms. This can cause the victims to lose most of their precious data. An overall breach costs an organization more than its actual annual cost if they are met with an unfortunate cybersecurity breach. In many cases, the users are directed toward corrupted pages, which can become a sign of major issues in the future.

Now, as we know, a cross-site scripting attack can bring gigantic issues to any network infrastructure and enter your critical assets’ databases. So let’s learn a few ways to help prevent the business owners from cybersecurity breaches.

Prevention Of XSS Attacks

Prevention of an XSS attack is not that easy as these cross site scripting attacks can take a multiple actionable steps to wash away and set the victim free. Here are such steps:

1. Filtered Input

While working on any particular website and before entering input into your computers or any other device, filtering is a must in such a case.

2. Encoding Of Output

Encoding the output is a major step toward preventing your critical assets from cross site scripting attacks. These attacks can cause major issues to your databases. In addition, encoding the output will help in converting the format of the data. The type of output context gets encoded with the help of HTML, JAVA script, CSS encoding, etc.

3. Use Of Content Security Policy

Such policy acts as an extra protective layer in the cybersecurity systems of organizations. Such content security policies help business owners to protect their assets in a much more defensive way. In addition, this feature helps detect probable loopholes in your security systems. Finally, it assists the users in the best way possible by preventing XSS attacks and other troublesome malware activities.
