The Best Ways to Boost JavaScript Protection

The Best Ways to Boost JavaScript Protection

Many web designers and application developers today want to protect their JavaScript code from unauthorized access. This article will provide you with twelve tips to boost one’s javascript protection.

1) Use a server-side script

What is required for this method: One must be able to understand and write PhP, AsP, etc., to use these types of scripts. They can largely help programmers in running scripts without any security problems like cross-site scripting. There are many different server-side programming languages but the most widely used ones that could be used to implement this method are:

 

PhP (Hypertext Preprocessor) is an open-source scripting language that is popularly known as server-side Html embedded scripting language.

AsP – This is a microsoft scripting language that is used in most web applications.

 

Perl (practical extraction & report language) – Perl was designed for text manipulation and is widely popular among system administrators. It is also widely used for Cgi programming on Unix servers, mainly because of its excellent support for string manipulation and regular expressions.

 

2) Make use of non-serialized object data storage formats The simplest way to store one’s javascript code securely is not storing it at all! The idea behind this method is that one should avoid serializing any sensitive data into a stateless protocol. Storing their javascript code inside the Html document is very dangerous because they are not allowed to access it outside of the web application’s context. That means that any user could easily send its content to some other place. Instead of using serialized object data storage formats, you should use literal strings containing the code. It will make their scripts more difficult for attackers to steal.

 

3) Make use of easily-guessable variable names This method is based on making use of variables with easily-guessable names that can be detected by attackers who want to steal them from the server. They have to remember that hackers know most programming languages just as well as they do and they can find these variables quickly during their hacking attempts if the names are not well chosen. It is recommended not to use names such as “user” or “password” because these variables are always the first that hackers will try.

 

4) Encode their functions and script locations This method is based on encoding the JavaScript code in a secure form by using functions like escape () and encode Uri (). There is a chance to defeat this type of protection if they only obfuscate the code instead of really encrypting it. Hackers can easily remove all text replacements from their JavaScript without any effort which means that their security measure isn’t good enough. One should also avoid embedding all script files into one HtmL file since it will make the process of removing textual replacements much easier for attackers. would be better to include them separately into the document.

 

5) Avoid using inline javascriptthe problem with obfuscating their code is that they can make it impossible to read but still make it very easy for attackers to modify it. If one wants to protect their scripts against both humans and computers, they should avoid using inline javascript since hackers could easily remove all of their protection measures inside it. Most web applications don’t need any inline it so this shouldn’t be a difficult task.

 

6) Make use of javascript frameworks There are many different well-known frameworks available that will help them complete this type of task in just a few lines of code instead of writing them themselves. These days there are certain well-tested libraries designed for protecting programming languages from being stolen or modified by attackers during the web application’s execution.

 

7) Use code obfuscators that aren’t javascript. This strategy is based on the usage of code protectors, which may be used to encrypt and compress their javascript source files such that the output only contains unreadable data, making it difficult to steal or modify. They must keep in mind that most hackers can bypass the protection provided by Javascript encoders because these tools are still fresh when compared to older hacking tactics. However, this is preferable than not securing their programmes at all.

 

8) Avoid hard-coding one’s sensitive data Look for different locations in their project where they could store some important values, such as session ids or database access credentials. There are many different techniques that they could use to access these values, but the most common practice is to use constant variables. One can then define them somewhere in their code and substitute their actual content just before the app runs on the user’s computer.

 

9) Make use of URL routing appended parameters This method is based on storing some sensitive information inside certain Uri-formatted parameters instead of using HttP Get requests. This way they are hiding the data by sending it through a different channel with an extra parameter named after its value. Hackers won’t be able to steal this kind of data easily because they will have no idea what value each parameter stores unless they intercept their data connection between their web application and its source code.

 

10) Avoid making any assumptions about one’s users This method is based on preparing their web application for cases when the client’s browser doesn’t support JavaScript. All they have to do is check whether the document object model is available and display a fallback message if JavaScript isn’t supported by a user’s browser. This way their users will be able to fully use their web application even if they don’t have javaScript enabled on their computers.

 

11) Make use of Html encoding It’s recommended that they encode all of the data displayed inside the HttP response body by using characters such as “<” and “&”. These entities would be filtered out from being returned to users so they won’t be able to steal any sensitive data from it since this encoding typically hides Html code from showing up in the output.

 

These were some amazing tips to boost javascript protection and a company named Appsealing provides all these ways for one’s security.
