Description: Node.js security involves practices and measures to protect Node.js applications from vulnerabilities and attacks. As Node.js is a JavaScript runtime environment on the server side, its popularity has grown exponentially in web application and cloud service development. However, this popularity also makes it an attractive target for attackers. Security in Node.js encompasses various aspects, including dependency management, input validation, authentication and authorization, as well as protection against common attacks such as code injection, cross-site scripting (XSS), and denial of service (DoS). To ensure security, developers must follow best practices, such as keeping dependencies updated, using security analysis tools, and applying secure coding principles. Additionally, implementing security measures in the infrastructure can help mitigate risks by running code in a controlled and scalable environment. In summary, Node.js security is a critical component in developing robust and reliable applications, requiring a proactive and conscious approach from developers.
