-- ============================================================================

-- Playbook: Web Infrastructure & TLS Hardening (Web Keywords)
-- Intent: Demonstrates 'nginx', 'vhost', 'hsts', and 'certificate'. 
-- Automates the remediation of weak SSL/TLS configurations and header security.
-- Infrastructure: Nginx/Apache, Let's Encrypt CA, Zelfire WAF, Rosecoin.
-- Note: 'reload' is used instead of 'restart' to ensure Zero-Downtime.

package soc.web_ops
use nginx, apache, ssl, network, slack, rosecoin

-- 1. CONFIGURATION GOVERNORS (Strongly Typed)
-- ============================================================================
⚙️ keep TARGET_SITE: String = "api.rocheston.internal"
⚙️ keep MIN_TLS_VERSION: String = "TLSv1.3"
⚙️ keep HSTS_MAX_AGE: Integer = 31536000 -- 1 Year

-- ============================================================================
-- 2. THE ENTRY POINT (The Check Block)
-- ============================================================================
🔥 check WebServerTLSValidation
  
  -- Trigger Gate: A daily scan detects an expiring certificate or weak 'ssl' ciphers
  ⚠️ when web_security_vulnerability_detected
    
    🔹 set target_host: String = event.hostname
    🔹 set current_vhost: vhost = event.site_config
    
    🚨 alert warning message "WEB VULNERABILITY: {TARGET_SITE} on {target_host} is using deprecated TLS. Hardening configuration."

    -- ============================================================================
    -- 3. THE TLS & CERTIFICATE LAYER (ssl, cert, chain, ca)
    -- ============================================================================
    ⚡ do
      
      -- Action 1: Rotate the SSL certificate using the internal CA
      -- Voice-friendly: "Rotate SSL certificate..."
      ☁️ ssl rotate certificate for TARGET_SITE via "Rocheston-CA"
      
      -- Action 2: Verify the full certificate 'chain' and 'ocsp' stapling
      🔹 set cert_status: Object = ssl verify chain for TARGET_SITE
      ☁️ ssl enable ocsp_stapling for TARGET_SITE
      
      -- Action 3: Update 'nginx' config to enforce TLS 1.3 only
      -- Voice-friendly: "Nginx update config..."
      ☁️ nginx config set "ssl_protocols" to MIN_TLS_VERSION in current_vhost

      -- ============================================================================
      -- 4. THE HEADER SECURITY LAYER (hsts, csrf, cors, cookie)
      -- ============================================================================
      -- Action 4: Enforce HSTS (HTTP Strict Transport Security)
      ☁️ nginx headers add "Strict-Transport-Security" value "max-age={HSTS_MAX_AGE}; includeSubDomains"
      
      -- Action 5: Secure 'cookie' attributes (HttpOnly, Secure, SameSite)
      ☁️ nginx headers modify "Set-Cookie" append "HttpOnly; Secure; SameSite=Strict"
      
      -- Action 6: Configure 'cors' to allow only trusted origins
      ☁️ nginx config set "add_header" "Access-Control-Allow-Origin" to "https://rocheston.com"
      
      -- Action 7: Implement 'rewrite' to force all 'http' traffic to 'https'
      ☁️ nginx rewrite "^/(.*)$" to "https://$host/$1" permanent

      -- ============================================================================
      -- 5. THE OPERATIONAL LAYER (reload, logs, rotate)
      -- ============================================================================
      -- Action 8: Test the configuration syntax before applying
      ⚠️ when nginx test_config == "SUCCESS"
         
         -- Action 9: Reload the service to apply changes gracefully
         ☁️ nginx reload target_host
         
         -- Action 10: Rotate the 'access.log' and 'error.log' to clear previous trace
         ☁️ nginx rotate logs on target_host
         
      🔴 end

      -- Action 11: Notify the Web-Ops team
      📡 notify slack channel "#web-infrastructure-alerts" message "🌐 *Web Security Hardened* \n*Site:* `{TARGET_SITE}` \n*Protocol:* `{MIN_TLS_VERSION}` \n*Status:* Cert Rotated. HSTS Enforced. Nginx Reloaded."
