When developing Lightning Web Components, security should be top of mind. To ensure that your applications are secure, you need to consider all the security considerations associated with developing Lightning Web Components.
Component Security
Lightning Web Components have a built-in security feature called Locker Service which prevents malicious code from running inside your components. This layer of protection is critical for ensuring the overall security of your application. Additionally, you should always be mindful of what components you’re allowing access to data and how sensitive the data is when you’re deciding which components to use in an application.
Cross site Scripting (XSS)
Cross site Scripting is an attack vector that allows malicious code to run inside scripts in an non-secure environment. It’s important that all Lightning Web Components are free from this vulnerability, as it can compromise the security of an entire application. Be sure to audit all code for any potential XSS vulnerabilities and ensure that all components adhere to the highest standards of security.
Access Control
Access control is critical when it comes to securing your applications and data. You need to ensure that only authorized users have access to sensitive data or certain parts of the application by implementing proper authentication and authorization measures. To help with this, Lightning has authentication methods such as OAuth 2 and SAML 2 which enforce user identity management policies and provide secure access control for your applications.
Secure Coding Practices
Secure coding practices are also important when developing Lightning Web Components as they help protect against potential vulnerabilities in your codebase. Using secure coding practices such as input validation.
