Protection Mechanism in JavaScript Attacks

Web pages are increasing due to the rapid development of information technology. Many tasks were previously only possible by installing software on the computer. However, cloud service satisfies cross-platform requirements with the arrival of the multi-device age. Original technologies such as Flash and other proprietary technologies from different manufacturers have made complex content simple, but they also have cross-platform problems. JavaScript is a common user-side scripting language to support the standardization of online pages. Using JavaScript arouses concern over its security. Hackers frequently change their attack strategies. Therefore, it is crucial to learn how to effectively and promptly fight against them. Thus, the defense of JavaScript on the client side is the main topic of this research. By integrating VirusTotal, a cloud security analysis service on the browser is developed for users to use the most recent malware database and examine different JavaScript files online to prevent harmful code from being executed.
