Description: JavaScript security refers to the measures taken to protect JavaScript code and its execution environment from vulnerabilities. Since JavaScript is a widely used programming language in web development, its security is crucial for protecting both users and applications. Vulnerabilities in JavaScript can be exploited by attackers to carry out attacks such as Cross-Site Scripting (XSS), code injections, and data theft. To mitigate these risks, various security practices are implemented, such as input validation, the use of Content Security Policy (CSP), and minimizing the exposure of sensitive data. Additionally, the Zero Trust security approach has become relevant in this context, as it promotes the idea that no entity, whether internal or external, should be trusted by default. This means that every access request to resources must be verified and authenticated, resulting in greater protection for applications using JavaScript. In cloud and distributed environments, where connectivity and interaction between devices are constant, JavaScript security becomes even more critical, as applications must be able to withstand attacks in an increasingly complex ecosystem.
