1. Input sanitization: We carefully validate and sanitize all user input before processing or rendering it on the frontend. This includes HTML escaping and removing potentially malicious code or scripts.
2. Content Security Policy (CSP): We implement strict CSP headers that define which sources of content are allowed to be loaded or executed on a webpage. This helps prevent the execution of any malicious scripts.
3. Output encoding: All dynamic content that is inserted into the DOM is properly encoded to prevent it from being interpreted as executable code.
4. Contextual output escaping: We employ contextual output escaping techniques based on the context in which the data is rendered. This ensures that any user input is adequately filtered and encoded based on its intended usage context.
5. Regular security audits: We conduct regular security audits of our frontend applications to identify and address any potential XSS vulnerabilities.
By implementing these measures, we ensure that our frontend applications are well-protected against cross-site scripting attacks.
