Security headers

HTTP response headers are the most effective protection layer against clickjacking, XSS, mixed content and tracking leaks — and they cost nothing. XICTRAQ checks the 9 most important headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP, CORP, COEP), additionally scans CSP for unsafe-inline/unsafe-eval/wildcards, scores the configuration and provides concrete code snippets for nginx, Apache, Caddy, IIS and Node/Express. Continuous monitoring: Free every 24 h, paid every 6 h.

# Header overview

The “Security” tab shows each of the 9 checked headers with status “Active” (green) or “Missing” (red) plus a brief explanation of what it protects against. Above, the overall Security Score (0–100) with its A+/A/B/C/D/F grade.

Security Headers

9 critical HTTP security headers

Strict-Transport-Security

Enforces HTTPS and prevents downgrade attacks

Active

Content-Security-Policy

Controls which resources can be loaded (XSS protection)

Active

X-Frame-Options

Prevents clickjacking via iframe embedding

Active

X-Content-Type-Options

Prevents browser MIME type sniffing

Active

Referrer-Policy

Controls what referrer information is sent

Active

Permissions-Policy

Restricts browser APIs like camera, microphone, geolocation

Active

Cross-Origin-Opener-Policy

Isolates the browsing context — protects against tab-napping / Spectre

Active

Cross-Origin-Resource-Policy

Prevents unauthorized cross-origin resource loading

Missing

Cross-Origin-Embedder-Policy

Requires explicit CORP/CORS for embedded resources (Spectre protection)

Missing

# What XICTRAQ checks

HSTS — enforce HTTPS

Strict-Transport-Security: max-age, includeSubDomains, preload directive (detected from the header itself). The header counts as “preload-ready” at max-age ≥ 1 year plus includeSubDomains and preload. Recommendation: max-age=63072000 (2 years), includeSubDomains, preload.

CSP — control content origin

Content-Security-Policy is scanned for common weaknesses: 'unsafe-inline', 'unsafe-eval', overly permissive source lists ('* in script-src'), missing default-src. Concrete hardening example for every finding.

X-Frame-Options / frame-ancestors

Clickjacking protection. Recommendation: SAMEORIGIN, or CSP frame-ancestors 'self'. The Security tab scores X-Frame-Options on its own based on header presence and reports it as missing even when CSP frame-ancestors is set — so set both for a green result.

Referrer-Policy

Controls what is sent as referrer on outbound links. Recommendation: strict-origin-when-cross-origin (browser default); for privacy-sensitive sites: no-referrer.

Permissions-Policy

Restricts browser APIs (camera, microphone, geolocation, USB, MIDI, payment) for the site and 3rd-party iframes. XICTRAQ proposes a default policy for typical marketing sites (everything off that is not needed).

X-Content-Type-Options

nosniff prevents MIME sniffing — critical when user uploads are served. Should be set on every site, zero configuration effort.

Cross-Origin headers (COOP/COEP/CORP)

Strictly isolates your browsing context from other origins — required for SharedArrayBuffer and WebAssembly threading. Optional for classic marketing pages, recommended for web apps. XICTRAQ security-score weighting: COOP 7 pts, CORP 4 pts, COEP is only detected and listed (no score contribution).

Info-leak detection

On top of the 9 headers, XICTRAQ checks for version disclosure: a Server header carrying a version number (e.g. nginx/1.24.0) and any X-Powered-By header are reported as findings. If both are clean (no version, no X-Powered-By), the score earns a bonus.

# How the security score is calculated

The score (0–100) sums fixed points: HTTPS as the base, the points below per present header, plus two bonuses. From that XICTRAQ derives the A+ to F grade. Re-scan and continuous monitoring use the exact same calculation.

# Point allocation (capped at 100)
HTTPS (Basis / base)                 +15
Content-Security-Policy              +20
Strict-Transport-Security (HSTS)     +12
X-Frame-Options                      + 8
X-Content-Type-Options               + 8
Referrer-Policy                      + 8
Permissions-Policy                   + 8
Cross-Origin-Opener-Policy (COOP)    + 7
Cross-Origin-Resource-Policy (CORP)  + 4
Cross-Origin-Embedder-Policy (COEP)  + 0
# Bonuses
HSTS preload-ready                   + 5
no info leaks (server version + X-Powered-By)  + 5

# Grade
A+ from 95   A from 85   B from 70   C from 50   D from 25   F < 25
A CSP set via meta tag still counts
If no Content-Security-Policy is set as an HTTP header, XICTRAQ looks for a Content-Security-Policy meta tag in the HTML and scores it equally (the full 20 points). A Content-Security-Policy-Report-Only header on its own earns no points because it enforces nothing — but its directives still feed the CSP analysis.

# Security Wizard (4 steps)

Instead of hand-crafting headers, the wizard guides you through four steps from scan to reports: 1) scan external sources (CspSourceScanner extracts every host used in scripts/frames/connections), 2) configure headers per directive (hash mode for inline scripts instead of unsafe-inline, token-based report-uri), 3) ready snippet per server (nginx/Apache/Caddy/IIS/Express) to copy, 4) review incoming CSP violation reports in the same panel — grouped by directive, blocked source and document URI.

After deploying: trigger a re-scan.
Don't roll out CSP blindly
A strict Content-Security-Policy can break your site if a tracker or chat widget gets blocked. Recommended flow: deploy first with Content-Security-Policy-Report-Only, collect reports (XICTRAQ ingests them under your account), only then enforce.

# Weekly security posture in plain language

Once a week, XICTRAQ summarises each active website's security posture from the most recent security scan — the score plus the six core headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy) — as a short plain-text paragraph in German and English. This text appears right on the Security Score card in the website detail. By default it is phrased rule-based (free); the AI phrasing is an optional operator toggle.
