FRONT-END SECURITY BEST PRACTICES

Summary from the TLDR Web Dev newsletter

Front-end security plays a critical role in safeguarding web applications against threats like cross-site scripting (XSS), cross-site request forgery (CSRF), and other vulnerabilities. Key practices for front-end security include input validation and sanitization to filter and clean user input, avoiding inline scripts and implementing Content Security Policies (CSPs) to restrict unauthorized code execution, using HTTPS for secure data transfer, conducting penetration testing to identify and address vulnerabilities, and efficient dependency management to keep libraries updated.
