Frequently Asked Questions
What are HTTP security headers?▼
HTTP security headers are response headers that browsers use to protect against common web vulnerabilities like XSS, clickjacking, MIME sniffing, and data injection. Setting them is a quick win for web security.
Which security headers should every site have?▼
At minimum: Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options, and Referrer-Policy. Content-Security-Policy is the most powerful but requires careful configuration.
What is Content-Security-Policy (CSP)?▼
CSP is a header that controls which sources of scripts, styles, images, and other resources the browser is allowed to load. A strong CSP prevents XSS attacks by blocking inline scripts and untrusted sources.
What is HSTS?▼
HTTP Strict Transport Security (HSTS) tells browsers to always use HTTPS for your domain. Once a browser sees the header, it won't load your site over HTTP for the duration of max-age. The includeSubDomains directive extends this to all subdomains.
