JavaScript is considered to be one of the most popular programming languages which have been utilised by developers across the globe for mobile application development systems. According to a comprehensive survey, approximately more than 67% of the web developers go with the option of preferring JavaScript and it is also utilised in more than 85% of the websites. But whenever it will be considered from the point of view of security it will be the fourth most vulnerable language in the world which is the main reason that people need to be clear about the concept of JavaScript protection since day one.
JavaScript is considered to be one of the most fundamental technologies which have been utilised for building web applications, mobile applications and server-side applications in the whole process so that it never becomes a big target for hackers.
Following are some of the most common JavaScript vulnerabilities so that JavaScript protection can be undertaken accordingly:
Cross-site scripting or XSS: This is considered to be one of the most common vulnerabilities in which attacks will be occurring outside the hacker and will successfully inject the malicious code into the vulnerable applications. The attackers will also go with the option of manipulating the HTML and JavaScript to trigger the malicious code and with the help of XSS, the vulnerable website will be based upon the execution of the malicious code of the user side. Hence, it is very much important for people to be clear about XSS in terms of highly-rated security vulnerability so that attackers can never gain unauthorised access in the whole process.
Cross-site request forgery: In this particular system the user session cookie will be hijacked to impersonate their browser session which is the main reason that people need to be clear about the concept of execution of the malicious code so that there is no unauthorised action on the website or application. Hackers can also go with the option of utilising this particular concept very easily and to avoid the developers also need to add the CSRF token in all forms of the website.
Server-side JavaScript injection: This is considered to be a new type of vulnerability in which everything will be commonly ignored by the developers and with the help of the right kind of server-side JavaScript injection hackers can go with the option of uploading and executing the malicious code with binary files into the webserver. The execution will be carried out of the server level and will ensure that there will be no severe impact on the website. This concept will further make sure that plug-in installation will be undertaken very easily and concerned people will be having good control over the entire process very efficiently.
The client-side issues: Whenever the developers will be introducing the application programming interface on the side of the client it will make the application much more vulnerable to different kinds of attacks. In all these kinds of cases, the poor web development practices will be very much usual in terms of living on each other which is the main reason that client-side browser scripts have to be perfectly undertaken in the whole process so that people can deal with sensitive data and user session ID without any kind of problem. This is considered to be the best possible way of dealing with sensitive user data in the whole process.
How to deal with the JavaScript protection issues?
The biggest possible advantage of JavaScript is that it will come with numerous open-source packages which will make the development process easy as well as faster but some of these kinds of packages are very much capable of compromising the security and welcoming different kinds of vulnerabilities in the whole process.
Following are some of the very basic tips to be followed by the people throughout the process:
1. Adoption of the runtime application self-protection system is very much important the whole process so that detection of the attacks can be undertaken in real-time and there is no problem throughout the process because the overall context of the behaviour to protect it will be perfectly undertaken without any manual human intervention.
2. The utilisation of the EVAL function is another very important aspect to be undertaken on the behalf of organisations and as a result of this particular system, organisations need to replace it with more secure functions throughout the process.
3. Encrypting things with SSL and HTTPS is another very important aspect to be taken into consideration by the people so that encryption can be perfectly undertaken and cookies are also set to be a secure limit so that utilisation of application will be undertaken very easily and efficiently.
4. The organisations also need to focus on the implementation of application programming interface security because it is very much important to be limited at the time of dealing with JavaScript-based applications. Starting things with the help of a secure application programming interface into the client-side JavaScript application is the best way of ensuring that accessibility has been restricted to the particular IP range in the whole process.
5. Depending on the top-notch quality JavaScript security analyser is another very important thing because these are the specific tools that will allow the organisations to examine the website or application from the inside to determine if it is vulnerable to the attackers or not.
6. Depending upon different kinds of scanning tools like ZAP is the best possible way of getting the website for numerous vulnerabilities at the same time very easily so that customisation can be undertaken without any kind of problem and everything is based upon easy to use intuitive interface throughout the process without any kind of hassle element in the whole process.
Hence, identification of the potential JavaScript security problem is the first step towards achieving the most secure application and ensuring proper business data so that organisations always need to actively look for vulnerabilities before deployment of the whole process. To deal with such things depending upon the companies like Appsealing is a great idea.
