 +===== Traefik security headers and CSP (DRY config) ===== 
 + 
 +Last updated: 25.09.2025 
 + 
 +==== High‑level design ==== 
 + 
 +  * One baseline for security headers: security-headers-base 
 +  * Small header variants you can compose: -noindex, -allowframes, -hsts-subdomains, cache-public 
 +  * Separate CORS middlewares: cors-default, cors-collections 
 +  * One base CSP: CSP-base (+ per‑service CSP middlewares that only add what’s different) 
 +  * Chains compose the above into per‑service “one-liners” you reference from docker-compose labels. 
 + 
 +==== Security headers ==== 
 + 
 +=== Baseline (security-headers-base) === 
 + 
 +Sets the shared hardening and sane defaults. Highlights: 
 + 
 +  * addVaryHeader: true 
 +  * contentTypeNosniff: true 
 +  * browserXssFilter: true 
 +  * referrerPolicy: same-origin 
 +  * permissionsPolicy: fullscreen=(self "https://smns-bw.org"), geolocation=*, midi=(), camera=(), usb=(), magnetometer=(), accelerometer=(), vr=(), speaker=(), ambient-light-sensor=(), gyroscope=(), microphone=(), payment=() 
 +  * HSTS: forceSTSHeader: true, stsSeconds: 31536000, stsPreload: false 
 +  * X-Frame-Options: frameDeny: true by default (prefer CSP frame-ancestors for allowlists) 
 +  * TLS/proxy awareness: sslRedirect: true; sslProxyHeaders.X-Forwarded-Proto: https 
 +  * Scrub response headers (customResponseHeaders): Server: "", X-Powered-By: "", X-Robots-Tag: "index, follow" 
 +  * Upstream request header: customRequestHeaders.X-Forwarded-Proto: https 
 +Rationale: 
 + 
 +  * Default deny framing (clickjacking defense); enable per service via -allowframes and control who via CSP. 
 +  * Keep includeSubdomains off by default to avoid accidental HSTS lock-in; use the variant when needed. 
 + 
 +==== Variants you can compose ==== 
 + 
 +  * security-headers-noindex 
 +    * Same as base, but X-Robots-Tag: "none,noarchive,nosnippet,notranslate,noimageindex" 
 +  * security-headers-allowframes 
 +    * Same as base, but frameDeny: false (use CSP frame-ancestors to specify who can frame) 
 +  * security-headers-hsts-subdomains 
 +    * Same as base, but stsIncludeSubdomains: true, stsSeconds: 63072000 
 +  * cache-public 
 +    * Adds Cache-Control: public to customResponseHeaders 
 + 
 +==== CORS middlewares ==== 
 + 
 +  * cors-default 
 +    * accessControlAllowMethods: GET, OPTIONS, PUT 
 +    * accessControlAllowHeaders: "*" 
 +    * accessControlMaxAge: 100 
 +    * addVaryHeader: true 
 +  * cors-collections 
 +    * Inherits cors-default + accessControlAllowOriginList: 
 +      * https://pydeepzoom.smns-bw.org 
 +      * https://pictures.smns-bw.org 
 + 
 +==== Content Security Policy (CSP) ==== 
 + 
 +=== Base CSP (CSP-base) === 
 + 
 +Applies to most services unchanged. 
 + 
 +<code yaml> CSP-base: headers: contentSecurityPolicy: &CSP_BASE > default-src 'self' 'unsafe-inline' 'unsafe-eval' *.smns-bw.org; frame-ancestors 'self' *.smns-bw.org; frame-src *.smns-bw.org; base-uri 'self'; form-action 'self'; img-src 'self' data:; connect-src 'self'; font-src 'self'; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval' *.smns-bw.org; </code> 
 + 
 +Notes: 
 + 
 +  * Only one CSP header is honored. Don’t stack multiple CSP middlewares in a single chain; “last header wins.” 
 +  * Use Report-Only during testing by duplicating to contentSecurityPolicyReportOnly. 
 + 
 +==== How to add a new service ==== 
 + 
 +  * If defaults are enough: 
 +    * Use secure-global chain. 
 +  * If it needs framing: 
 +    * Use security-headers-allowframes in the chain and set CSP frame-ancestors to the exact allowlist. 
 +  * If it needs special CORS: 
 +    * Add or create a cors-<service> middleware and include it in the chain. 
 +  * If it needs special CSP: 
 +    * Copy CSP-base to CSP-<service> and append only the minimal deltas (new hosts/tokens). 
 +  * Wire it in docker-compose: 
 +    * traefik.http.routers.<name>.middlewares=secure-<name>@file 
 +==== Verification (quick commands) ==== 
 + 
 +  * Check headers: 
 +    * curl -sI https://<host> | egrep -i "strict-transport-security|x-frame-options|x-content-type-options|referrer-policy|permissions-policy|x-robots-tag" 
 +    * Check CSP is present (and only once): 
 +    * curl -sI https://<host> | grep -i "content-security-policy" 
 +  * Check CORS (preflight example): 
 +    * curl -sI -X OPTIONS https://<host>/ -H "Origin: https://example.com" -H "Access-Control-Request-Method: GET" 
 +  * Check robots indexing: 
 +    * curl -sI https://<host>/ | grep -i x-robots-tag 
 + 
 +==== Operational notes ==== 
 + 
 +  * Prefer CSP frame-ancestors over X-Frame-Options for precise embedding control. 
 +  * Consider a Report-Only CSP during rollouts (duplicate middleware with contentSecurityPolicyReportOnly). 
 +  * HSTS includeSubdomains is opt-in via variant to avoid unintentional hard lock-in. 
 +  * If a page doesn’t render: check the browser console for CSP violations first; add only the specific host/type needed. 
 +==== Appendix: Anchor usage ==== 
 +We used YAML anchors to stay DRY: 
 + 
 +  * &SEC_BASE / *SEC_BASE for baseline headers. 
 +  * &CSP_BASE / *CSP_BASE for base CSP string. 
 +This keeps the source config compact while allowing targeted overrides.
