# Site security policy

The generated HTML includes a baseline Content Security Policy and referrer
policy so browsers receive protection even before an edge rule is installed.
The production edge must also set the following HTTP response headers for
`familyfed.ie`:

```text
Content-Security-Policy: default-src 'self'; base-uri 'self'; object-src 'none'; frame-ancestors 'none'; img-src 'self' data: https:; font-src 'self' data:; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' https://static.cloudflareinsights.com; connect-src 'self' https:; frame-src https://www.youtube.com https://www.youtube-nocookie.com https://player.vimeo.com; form-action 'self' mailto: https:; upgrade-insecure-requests
Cross-Origin-Opener-Policy: same-origin
Cross-Origin-Resource-Policy: same-site
Permissions-Policy: camera=(), geolocation=(), microphone=(), payment=(), usb=()
Referrer-Policy: strict-origin-when-cross-origin
Strict-Transport-Security: max-age=63072000; includeSubDomains
X-Content-Type-Options: nosniff
X-Frame-Options: DENY
```

The rule must be scoped to `http.host eq "familyfed.ie"`. If Plausible is
enabled on a non-default host, add that exact origin to `script-src`.

## Origin access

The public website virtual host must accept HTTP/HTTPS traffic only from
Cloudflare's published IPv4 and IPv6 ranges. Keep the S3 deployment API on
`s3-sites.bcgen.ie` reachable by Forgejo runners; do not apply the website
virtual-host restriction to the S3 API listener. Authenticated Origin Pulls or
a Cloudflare Tunnel are preferable when supported by the origin proxy.

Verify the restriction from a non-Cloudflare client with:

```bash
curl --resolve familyfed.ie:443:ORIGIN_IP https://familyfed.ie/
```

The request must fail before an HTTP response is served, while the normal
`https://familyfed.ie/` request must continue to succeed through Cloudflare.
