📋 Steps to Complete the Project

Step 1: Create Xcode Project

  1. Open Xcode
  2. File → New → Project
  3. Select macOS → App
  4. Configure:
    • Product Name: Bastion
    • Team: Your team
    • Organization Identifier: com.jordankoch (or your identifier)
    • Interface: SwiftUI
    • Language: Swift
    • Storage: None
  5. Save Location: /Volumes/Data/xcode/Bastion (Important: Use this exact path)
  6. When prompted, do not create a Git repository (already exists)

Step 2: Add Source Files to Xcode Project

All source files are already created in the correct directories. In Xcode:

  1. Delete the auto-generated BastionApp.swift and ContentView.swift (we have better ones)

  2. Add existing files to the project:

    • Right-click on the Bastion folder in Xcode
    • Choose "Add Files to Bastion..."
    • Select all directories:
      • AI/
      • Models/
      • Security/
      • Utilities/
      • Views/
    • Make sure "Copy items if needed" is unchecked (files are already in place)
    • Make sure "Create groups" is selected
    • Click "Add"

  3. Add the new BastionApp.swift:

    • Drag Bastion/BastionApp.swift into the Xcode project
    • Replace the auto-generated one

Step 3: Configure Build Settings

  1. Set Deployment Target:

    • Select the Bastion project in Navigator
    • Select the Bastion target
    • General tab → Deployment Info
    • Set macOS Deployment Target to 13.0 or higher

  2. Configure App Sandbox (Important for Network Access):

    • Select the Bastion target
    • Signing & Capabilities tab
    • Add capability: App Sandbox
    • Enable:
      • ✅ Incoming Connections (Server)
      • ✅ Outgoing Connections (Client)
      • ✅ Network → All (for network scanning)

  3. Disable App Sandbox (Alternative - for full network access):

    • Or disable App Sandbox entirely for unrestricted network access
    • This is recommended for penetration testing tools

  4. Entitlements:

    • Add entitlement: com.apple.security.network.client = YES
    • Add entitlement: com.apple.security.network.server = YES

Step 4: Add Info.plist Keys

Add these keys to Info.plist for network access:

<key>NSLocalNetworkUsageDescription</key>
<string>Bastion needs local network access to scan for devices and security vulnerabilities on YOUR network.</string>
<key>NSBonjourServices</key>
<array>
    <string>_ssh._tcp</string>
    <string>_http._tcp</string>
</array>

Step 5: Build and Run

  1. Select My Mac as the run destination
  2. Press Cmd+B to build
  3. Fix any import errors (should be minimal)
  4. Press Cmd+R to run

Expected First Launch:

  • Legal warning dialog will appear
  • Accept terms to proceed
  • Dashboard will load

Step 6: Test Basic Functionality

  1. Network Scan:

    • Enter your local network CIDR (e.g., 192.168.1.0/24)
    • Click "Scan Network"
    • Watch devices appear in the dashboard

  2. CVE Database:

    • Go to Settings (Cmd+,)
    • Navigate to "CVE Database" tab
    • Click "Download Database" (~2GB download)
    • This will take 10-15 minutes

  3. AI Backend:

    • Go to Settings → "AI Backend" tab
    • Select Ollama, MLX, or TinyLLM
    • Test AI features in "AI Insights" tab

🎨 Features Implemented

Core Functionality

✅ Pure Swift network scanner (no external dependencies) ✅ Port scanning (common 23 ports) ✅ Service fingerprinting with banner grabbing ✅ CVE database downloader (NVD JSON feeds) ✅ SSH brute force testing ✅ Default credential testing (1000+ combinations) ✅ Web vulnerability scanning (SQLi, XSS, directory traversal) ✅ AI attack orchestration (Ollama/MLX/TinyLLM) ✅ PDF report generation ✅ Multi-window glassmorphic UI

Safety Features

✅ Local IP enforcement (blocks internet scanning) ✅ Legal warning on first launch ✅ Rate limiting to prevent DoS ✅ Audit logging ✅ Confirmation dialogs before attacks

🔒 Safety & Legal

CRITICAL: This is a WHITE HAT tool for YOUR OWN network only.

Built-in safety features:

  • Local IP only: Refuses to scan public IPs (192.168.x.x, 10.x.x.x, 172.16-31.x.x)
  • Legal warning: Mandatory acceptance on first launch
  • Audit logging: All actions logged to ~/Library/Application Support/Bastion/audit.log
  • Rate limiting: Maximum 10 requests/second

Use cases:

  • Testing YOUR home network
  • Assessing YOUR office network (with permission)
  • Security research in authorized environments
  • Penetration testing with signed contracts

DO NOT:

  • Scan networks you don't own
  • Use against internet targets
  • Attempt unauthorized access

📦 Dependencies

Required (Built-in macOS)

  • Foundation
  • SwiftUI
  • Network (for network scanning)
  • PDFKit (for report generation)
  • AppKit (for UI components)

Optional (External)

  • Ollama: brew install ollama (for AI features)
  • MLX: pip install mlx-lm (alternative AI backend)
  • TinyLLM: Docker container (alternative AI backend)

No other external dependencies required!

🚀 Next Steps After Build

  1. Download CVE Database:

    • First launch: Go to Settings → CVE Database
    • Click "Download Database"
    • Wait for ~2GB download (10-15 minutes)

  2. Configure AI Backend:

    • Install Ollama: brew install ollama
    • Start Ollama: ollama serve
    • Pull model: ollama pull llama2
    • In Bastion Settings, select "Ollama" backend

  3. Run First Scan:

    • Enter your local network CIDR
    • Click "Scan Network"
    • Wait for devices to be discovered
    • View security scores and vulnerabilities

  4. Export Reports:

    • After scanning, click "Export Report"
    • Professional PDF generated with AI analysis

🐛 Troubleshooting

"Cannot connect to network devices"

  • Check App Sandbox settings
  • Enable network entitlements
  • Run as administrator if needed

"CVE database download fails"

  • Check internet connection
  • NVD servers may be rate-limited
  • Try downloading individual years first

"AI features not working"

  • Install Ollama: brew install ollama
  • Start Ollama server: ollama serve
  • Pull a model: ollama pull llama2
  • Check Settings → AI Backend status

"Compilation errors"

  • Check all files are added to target
  • Verify deployment target is macOS 13.0+
  • Clean build folder (Cmd+Shift+K)

📝 What Needs Completion

The following are placeholder views that need full implementation:

  1. AttackLogView.swift - Live terminal-style attack log (currently placeholder)
  2. AIInsightsView.swift - AI recommendations UI (currently placeholder)
  3. DeviceListView.swift - Detailed device list table (currently placeholder)
  4. VulnerabilitiesView.swift - CVE details view (currently placeholder)
