Protection from Cross-Site Scripting (XSS) attacks
Here are some effective techniques to protect against Cross-Site Scripting (XSS) attacks: Input Validation : Implement strict input validation on both the client and server sides. Validate and sanitize all user-supplied data, including form inputs, query parameters, and cookies, to ensure they contain only expected and safe values. Output Encoding : Properly encode all user-generated content before displaying it on web pages. Use appropriate encoding functions or libraries that prevent browsers from interpreting the content as executable code. Content Security Policy (CSP) : Implement a Content Security Policy that defines which sources of content are considered trusted and allowed to be loaded by the browser. This helps mitigate XSS attacks by limiting the execution of scripts to trusted sources. HTTP-only Cookies : Set the "HTTP-only" flag for cookies. This prevents malicious scripts from accessing cookies via client-side scripting, reducing the risk of session hijacking a...
