# HTTP Security Headers
|
|
|
|
Modern browsers expect specific security headers to protect your users. Charon automatically adds industry-standard headers including Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
|
|
|
|
## Overview
|
|
|
|
HTTP security headers instruct browsers how to handle your content securely. Without them, your site remains vulnerable to clickjacking, XSS attacks, protocol downgrades, and MIME-type confusion. Charon provides a visual interface for configuring these headers without memorizing complex syntax.
|
|
|
|
### Supported Headers
|
|
|
|
| Header | Purpose |
|
|
|--------|---------|
|
|
| **HSTS** | Forces HTTPS connections, prevents downgrade attacks |
|
|
| **Content-Security-Policy** | Controls resource loading, mitigates XSS |
|
|
| **X-Frame-Options** | Prevents clickjacking via iframe embedding |
|
|
| **X-Content-Type-Options** | Stops MIME-type sniffing attacks |
|
|
| **Referrer-Policy** | Controls referrer information leakage |
|
|
| **Permissions-Policy** | Restricts browser feature access (camera, mic, geolocation) |
|
|
| **Cross-Origin-Opener-Policy** | Isolates browsing context |
|
|
| **Cross-Origin-Resource-Policy** | Controls cross-origin resource sharing |
|
|
|
|
## Why Use This
|
|
|
|
- **Browser Protection**: Modern browsers actively check for security headers
|
|
- **Compliance**: Many security audits and standards require specific headers
|
|
- **Defense in Depth**: Headers add protection even if application code has vulnerabilities
|
|
- **No Code Changes**: Protect legacy applications without modifying source code
|
|
|
|
## Security Presets
|
|
|
|
Charon offers three ready-to-use presets based on your security requirements:
|
|
|
|
### Basic (Production Safe)
|
|
|
|
Balanced security suitable for most production sites. Enables essential protections without breaking typical web functionality.
|
|
|
|
- HSTS enabled (1 year, includeSubdomains)
|
|
- X-Frame-Options: SAMEORIGIN
|
|
- X-Content-Type-Options: nosniff
|
|
- Referrer-Policy: strict-origin-when-cross-origin
|
|
|
|
### Strict (High Security)
|
|
|
|
Enhanced security for applications handling sensitive data. May require CSP tuning for inline scripts.
|
|
|
|
- All Basic headers plus:
|
|
- Content-Security-Policy with restrictive defaults
|
|
- Permissions-Policy denying sensitive features
|
|
- X-Frame-Options: DENY
|
|
|
|
### Paranoid (Maximum)
|
|
|
|
Maximum security for high-value targets. Expect to customize CSP directives for your specific application.
|
|
|
|
- All Strict headers plus:
|
|
- CSP with nonce-based script execution
|
|
- Cross-Origin policies fully restricted
|
|
- All permissions denied by default
|
|
|
|
## Configuration
|
|
|
|
### Using Presets
|
|
|
|
1. Navigate to **Hosts** → Select your host → **Security Headers**
|
|
2. Choose a preset from the dropdown
|
|
3. Review the applied headers in the preview
|
|
4. Click **Save** to apply
|
|
|
|
### Custom Header Profiles
|
|
|
|
Create reusable header configurations:
|
|
|
|
1. Go to **Settings** → **Security Profiles**
|
|
2. Click **Create Profile**
|
|
3. Name your profile (e.g., "API Servers", "Public Sites")
|
|
4. Configure individual headers
|
|
5. Save and apply to multiple hosts
|
|
|
|
### Interactive CSP Builder
|
|
|
|
The CSP Builder provides a visual interface for constructing Content-Security-Policy:
|
|
|
|
1. Select directive (script-src, style-src, img-src, etc.)
|
|
2. Add allowed sources (self, specific domains, unsafe-inline)
|
|
3. Preview the generated policy
|
|
4. Test against your site before applying
|
|
|
|
## Security Score Calculator
|
|
|
|
Each host displays a security score from 0-100 based on enabled headers:
|
|
|
|
| Score Range | Rating | Description |
|
|
|-------------|--------|-------------|
|
|
| 90-100 | Excellent | All recommended headers configured |
|
|
| 70-89 | Good | Core protections in place |
|
|
| 50-69 | Fair | Basic headers only |
|
|
| 0-49 | Poor | Missing critical headers |
|
|
|
|
## When to Use Each Preset
|
|
|
|
| Scenario | Recommended Preset |
|
|
|----------|-------------------|
|
|
| Marketing sites, blogs | Basic |
|
|
| E-commerce, user accounts | Strict |
|
|
| Banking, healthcare, government | Paranoid |
|
|
| Internal tools | Basic or Strict |
|
|
| APIs (no browser UI) | Minimal or disabled |
