Frequently Asked Questions
Why are security HTTP headers important?
Security headers instruct browsers on how to handle content, preventing cross-site scripting (XSS), clickjacking, MIME-sniffing, and data injection attacks.
What is a Content Security Policy (CSP)?
CSP restricts the domains from which scripts, styles, images, and fonts can be loaded, blocking unauthorized external script injections.
