## Web security aspects
| config file | environment | **default** and example value | description |
|-------------------------------|--------------------------------|-------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `hsts` | | `{"enable": true, "maxAgeSeconds": 31536000, "includeSubdomains": true, "preload": true}` | [HSTS](https://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security) options to use with HTTPS (default is the example value, max age is a year) |
| | `CMD_HSTS_ENABLE` | **`true`** or `false` | set to enable [HSTS](https://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security) if HTTPS is also enabled (default is ` true`) |
| | `CMD_HSTS_INCLUDE_SUBDOMAINS` | **`true`** or `false` | set to include subdomains in HSTS (default is `false`) |
| | `CMD_HSTS_MAX_AGE` | **`31536000`**, `60 * 60 * 24 * 365` | max duration in seconds to tell clients to keep HSTS status (default is a year) |
| | `CMD_HSTS_PRELOAD` | `true` or **`false`** | whether to allow preloading of the site's HSTS status (e.g. into browsers) |
| `csp` | | `{"enable": true, "addDefaults": true}` | Nested object to configure the Content Security Policy |
| `csp.enable` | `CMD_CSP_ENABLE` | **`true`** or `false` | Whether to apply a `Content-Security-Policy` header to responses. We don't recommend disabling this option, as it significantly reduces the security of the application. |
| `csp.addDefaults` | | **`true`** or `false` | Disable to not include the default CSP. Be careful, this will break the application if the correct directives are not set manually. |
| `csp.directives` | | **no default**, `{"scriptSrc": "trustworthy-scripts.example.com"}` | Custom CSP directives. These are passed to Helmet - see [their documentation](https://helmetjs.github.io/docs/csp/) for more information on the format. |
| `csp.addDisqus` | `CMD_CSP_ADD_DISQUS` | **`false`** or `true` | Enable to allow users to add Disqus comments to their notes or presentations. We don't recommend enabling this option, as it increases the attack surface of XSS attacks. |
| `csp.addGoogleAnalytics` | `CMD_CSP_ADD_GOOGLE_ANALYTICS` | **`false`** or `true` | Enable to allow users to add Google Analytics to their notes. We don't recommend enabling this option, as it increases the attack surface of XSS attacks. |
| `csp.upgradeInsecureRequests` | | **`auto`** or `true` or `false` | By default (`auto`), insecure (HTTP) requests are upgraded to HTTPS via CSP if `useSSL` is on. To change this behaviour, set to either `true` or `false`. |
| `csp.reportUri` | `CMD_CSP_REPORTURI` | **`undefined`**, `https://<someid>.report-uri.com/r/d/csp/enforce` | Allows to add a URL for CSP reports in case of violations. |
| `csp.allowFraming` | `CMD_CSP_ALLOW_FRAMING` | **`true`** or `false` | Disable to disallow embedding of the instance via iframe. We **strongly recommend disabling** this option, as it increases the attack surface of XSS attacks. |
| `csp.allowPDFEmbed` | `CMD_CSP_ALLOW_PDF_EMBED` | **`true`** or `false` | Disable to disallow embedding PDFs. We recommend disabling this option, as it increases the attack surface of XSS attacks. |
| `cookiePolicy` | `CMD_COOKIE_POLICY` | **`lax`**, `strict` or `none` | Set a SameSite policy whether cookies are send from cross-origin. Be careful: setting a SameSite value of none without https breaks the editor. |
| `rateLimitNewNotes` | `CMD_RATE_LIMIT_NEW_NOTES` | **`20`**, `0` or any positive number | Sets the maximum amount of new note creations per 5-minute window per user. Can be disabled by setting to `0`. |
