For Android, detect Internet Connection Discovery by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed. Correlate API Calls via Application Vetting / Instrumented Dynamic Analysis [Dynamic API/runtime trace: ConnectivityManager.getActiveNetworkInfo() or InetAddress.isReachable() called by app NOT IN $ConnectivityAllowList$ at app launch or on schedule without user action]; Application State via Android Enterprise / EMM [Managed package inventory/status and package metadata]; Network Connection Creation via Android Enterprise Network Logging / Enterprise VPN [DevicePolicyManager.retrieveNetworkLogs(): DnsEvent / ConnectEvent; VPN flow metadata]. Alert on a sequence or state change inconsistent with the device/app baseline, approved management policy, or expected user workflow; do not infer unobserved API calls, file/process activity, or payload content from management state alone.

For iOS, detect Internet Connection Discovery by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed. Correlate API Calls via Application Vetting / Instrumented Dynamic Analysis [Dynamic API/runtime trace: NWPathMonitor.start() or SCNetworkReachabilityGetFlags() called by app NOT IN $ConnectivityAllowList$ at launch or on background schedule]; Application State via Apple MDM [InstalledApplicationList / ManagedApplicationList]; Network Connection Creation via Apple Network Extension / Enterprise VPN [NEFilterFlow / per-app VPN / secure-web-gateway flow metadata]. Alert on a sequence or state change inconsistent with the device/app baseline, approved management policy, or expected user workflow; do not infer unobserved API calls, file/process activity, or payload content from management state alone.
