-- 👤 Creator: Haja Mo
-- 🏢 Organization: Rocheston
-- 📜 Platform: Rocheston Agentic AI Cybersecurity Automation Platform
-- ============================================================================

-- Playbook: Browser & Client-Side Interdiction (Browser Keywords)
-- Intent: Demonstrates 'csp', 'sri', 'session_hijack', and 'phishing_page'. 
-- Prevents credential theft and unauthorized script injection at the browser level.
-- Infrastructure: Zelfire WAF, Browser Extension Agent, Enterprise Chrome/Edge.
-- Note: 'hsts_preload' is verified to ensure all client-to-server traffic is encrypted.

-- 1. CONFIGURATION GOVERNORS (Strongly Typed)
-- ============================================================================
⚙️ keep ENFORCE_SRI: Boolean = true
⚙️ keep CSP_POLICY: String = "default-src 'self'; script-src 'self' https://trusted.cdn.com;"
⚙️ keep COOKIE_MODE: String = "Strict"

-- ============================================================================
-- 2. THE ENTRY POINT (The Check Block)
-- ============================================================================
🔥 check ClientSideIntegrity
  
  -- Trigger Gate: Browser Agent detects a 'phishing_page' or 'session_cookie' theft attempt
  ⚠️ when browser_threat_detected or suspicious_extension_activity
    
    🔹 set target_user: identity = event.user_principal
    🔹 set source_url: String = event.malicious_url
    🔹 set threat_vector: String = event.vector -- e.g., "Cookie-Theft"
    
    🚨 alert critical message "CLIENT BREACH: {threat_vector} detected on {target_user}'s browser. Source: {source_url}."

    -- ============================================================================
    -- 3. THE RUNTIME PROTECTION (csp, sri, sandbox, same_origin)
    -- ============================================================================
    ⚡ do
      
      -- Action 1: Enforce Content Security Policy (CSP) to block inline scripts
      -- Voice-friendly: "Browser enforce CSP..."
      ☁️ browser enforce_policy "CSP" value CSP_POLICY for target_user
      
      -- Action 2: Verify Subresource Integrity (SRI) for all loaded assets
      -- This ensures third-party scripts haven't been tampered with.
      ⚠️ when ENFORCE_SRI == true
         ☁️ browser verify_sri for "all-external-js"
      🔴 end
      
      -- Action 3: Identify if the site is bypassing 'same_origin' or 'cors_policy'
      🔹 set cors_violation: Boolean = browser check_cors for source_url
      
      ⚠️ when cors_violation == true
         🚨 alert critical message "CORS VIOLATION: Unauthorized cross-origin request detected from {source_url}."
         ☁️ browser terminate_tab source_url
      🔴 end

      -- ============================================================================
      -- 4. THE SESSION PROTECTION (cookie_theft, session_hijack, same_site)
      -- ============================================================================
      -- Action 4: Rotate all 'session_cookie' tokens for the impacted user
      -- Voice-friendly: "Rotate session cookies..."
      ☁️ identity rotate_sessions for target_user
      
      -- Action 5: Set all cookies to 'SameSite=Strict' and 'HttpOnly'
      ☁️ browser set_cookie_attributes "all" same_site COOKIE_MODE http_only true
      
      -- Action 6: Block the malicious 'phishing_page' across the entire fleet
      -- Prevents 'tabnabbing' or 'mixed_content' lures from spreading.
      ☁️ network block url source_url global

      -- ============================================================================
      -- 5. THE HEADER & COMPLIANCE LAYER (x_frame_options, hsts_preload)
      -- ============================================================================
      -- Action 7: Verify 'x_frame_options' to prevent clickjacking
      ☁️ waf add_header "X-Frame-Options" "DENY" for all_sites
      
      -- Action 8: Enforce 'hsts_preload' to prevent SSL-Stripping
      ☁️ browser enforce_hsts_preload for "rocheston.io"

      -- Action 9: Notify the Security Operations Center
      📡 notify slack channel "#browser-security-alerts" message "🌐 *Browser Interdiction Successful* \n*User:* `{target_user}` \n*Vector:* `{threat_vector}` \n*Status:* Malicious Tab Closed. Sessions Rotated. URL Blocked Global. CSP Enforced."
