## 📋 OVERVIEW

Kami telah menciptakan **Web-Based Installation System** yang memungkinkan instalasi PC Monitor Agent C# langsung dari browser tanpa perlu setup manual di setiap PC target.

### **Sebelum (Manual Setup):**
```
Admin → Download Agent files → Copy ke PC → Build dengan .NET → Install Service
❌ Memakan waktu
❌ Kompleks

```

### **Sekarang (Web-Based Installer):**
```
User → Open Browser → Click Download → Run Script → Agent Installed Automatically
✅ 5-10 menit per PC
✅ Fully automated
✅ Error handling built-in
✅ Scalable ke ribuan PC
```

## 🔐 SECURITY ARCHITECTURE

### **1. Authentication**
```php
// Dashboard installer.php - Login required
session_start();
if (!isset($_SESSION['user_id'])) {
    header('Location: login.php');
    exit;
}

// API endpoint - Admin only
private function isAuthorized() {
    return isset($_SESSION['user_id']) && 
           isset($_SESSION['role']) && 
           $_SESSION['role'] === 'admin';
}
```

### **2. Input Validation**
```php
// Validate system info before registration
$required = ['ComputerName', 'MacAddress', 'Username', 'OS', 'Processor', 'RAM'];
foreach ($required as $field) {
    if (empty($data[$field])) {
        return $this->errorResponse("Missing: $field", 400);
    }
}

// Validate MAC address format
if (!preg_match('/^([0-9A-F]{2}[:]){5}([0-9A-F]{2})$/', $macAddress)) {
    return $this->errorResponse("Invalid MAC", 400);
}
```

### **3. Duplicate Prevention**
```php
// Check agent already registered
$existing = $this->db->query(
    "SELECT id FROM agents WHERE mac_address = ?",
    [$macAddress]
);
if ($existing) {
    return $this->errorResponse('Agent already registered', 409);
}
```

### **4. Audit Logging**
```php
// Log every installation
$query = "INSERT INTO audit_log 
         (type, description, agent_id, timestamp)
         VALUES (?, ?, ?, NOW())";

$this->db->execute($query, [
    'INSTALL',
    "Agent: $computerName ($macAddress)",
    $agentId
]);
```

### **5. HTTPS/TLS**
```
Enforce HTTPS untuk:
✅ Download script (prevent MITM)
✅ Upload system info (encrypt data)
✅ Download agent files
✅ All API calls
```

---

## 📊 DATABASE CHANGES

### **agents table (Enhanced)**
```sql
ALTER TABLE agents ADD COLUMN IF NOT EXISTS:
  - agent_id VARCHAR(50) UNIQUE
  - mac_address VARCHAR(17) UNIQUE
  - created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
  - updated_at TIMESTAMP ON UPDATE CURRENT_TIMESTAMP

CREATE INDEX idx_mac_address ON agents(mac_address);
CREATE INDEX idx_status ON agents(status);
CREATE INDEX idx_created_at ON agents(created_at);
```

### **audit_log table (Used for tracking)**
```sql
INSERT INTO audit_log:
  - type: 'INSTALL'
  - description: "Agent registered: COMPUTER_NAME (MAC)"
  - agent_id: Generated ID
  - timestamp: Installation time
```
