Almost every business and every institution today uses web applications in some way. It is very important that these web applications work quickly, effectively and reliably. For this reason, web application security is a very critical issue. In this article, we will cover web application security, focusing on JavaScript.
What is JavaScript and What Does It Do?
JavaScript is one of the most popular languages used in web development. JavaScript makes web pages efficient and interactive. It is used to provide users with a richer user experience in terms of visual and functionality. JavaScript is also used to develop web applications that interact with the server.
JavaScript and Security
Web application security means preventing or minimizing potential vulnerabilities in web applications. JavaScript is very important for web application security. Because JavaScript is an easy-to-use and widely used language. However, this convenience may cause significant security vulnerabilities for the web application.
JavaScript Security Dangers
- XSS (Cross-Site Scripting): In this type of attack, the attacker changes the content that visitors see on the web page.
- Unauthorized Access:An attacker can steal an element from the web page and place it on users' computers.
- Code Injection:The attacker can inject malicious code into the web page.
- Fake Links:The attacker can provide fake links on the web page.
Recommendations for JavaScript Security
- Coding Standards:Establishing JavaScript coding standards is necessary to incorporate safe programming principles into operations and the use of code security.
- Security Software:Using security software for JavaScript or other web technologies will increase web application security.
- Secure Storage:Secure controls should be used in JavaScript coded applications to reduce unexpected security vulnerabilities.
JavaScript can create significant issues in web application security, but when used correctly, JavaScript provides convenience to web application developers and users. For this reason, security activities must be monitored in web applications.
