🔴 TIER 1: Critical Missing Features (High Impact, Medium Effort)

1. Real-Time Network Monitoring Dashboard ⭐⭐⭐⭐⭐

Why You Need This:

• Current scanning is manual or scheduled
• No visibility into live network activity
• Can't detect intrusions in real-time
• Miss brief security events between scans

What It Would Do:

• Continuous packet monitoring (non-intrusive)
• Live device connections/disconnections
• Real-time port activity visualization
• Bandwidth usage per device
• Protocol breakdown (TCP/UDP/ICMP percentages)
• Alert on new connections immediately

Implementation:

// Real-time monitoring using pcap
class RealtimeNetworkMonitor: ObservableObject {
    @Published var liveConnections: [Connection] = []
    @Published var bandwidthByDevice: [String: BandwidthStats] = [:]
    @Published var recentEvents: [NetworkEvent] = []

    func startMonitoring(interface: String = "en0") async {
        // Use libpcap to capture packets
        // Filter for local network only
        // Non-blocking, low overhead
        // Update UI every 500ms
    }
}

struct Connection {
    let source: String
    let destination: String
    let port: Int
    let protocol: String
    let bytes: Int
    let startTime: Date
}

UI:

        // Return baseline model
    }

    func detectAnomalies(current: ScanResult, baseline: NetworkBaseline) -> [Anomaly] {
        // Compare current to baseline
        // Flag significant deviations
        // Calculate anomaly score
    }
}

struct Anomaly {
    let type: AnomalyType
    let severity: Int  // 1-10
    let description: String
