For Android, detect Domain Generation Algorithms by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed. Correlate Application Permission via Android Enterprise DPC / Application Vetting [DevicePolicyManager.getPermissionGrantState(); PackageManager manifest/requested-permission review]; Network Traffic Content via Enterprise Secure Web Gateway / Proxy [DNS/HTTP(S) inspection or proxy transaction metadata where enterprise decryption/inspection is deployed]; Network Traffic Flow 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.
| Data Component | Name | Channel |
|---|---|---|
| Application Permission (DC0114) | android:DevicePolicyManager | DevicePolicyManager.getPermissionGrantState(); PackageManager manifest/requested-permission review |
| Network Traffic Content (DC0085) | webproxy:applog | DNS/HTTP(S) inspection or proxy transaction metadata where enterprise decryption/inspection is deployed |
| Network Traffic Flow (DC0078) | android:EnterpriseNetworkLog | DevicePolicyManager.retrieveNetworkLogs(): DnsEvent / ConnectEvent; VPN flow metadata |
| Field | Description |
|---|---|
| MDMApprovedCatalog | MDM-managed app list. |
| DGAEntropyThreshold | Default 3.5 bits Shannon. Calibrate from fleet DNS baseline. |
| DGALabelLength | Default 12 characters. |
| DGACandidateThreshold | Default 10 high-entropy queries within window. |
| DGAWindow | Default 60s. |
| DomainAgeThreshold | Default 30 days — newly-registered C2 domain. |
For iOS, detect Domain Generation Algorithms by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed. Correlate Application Permission via Application Vetting [Code-signing entitlements and Info.plist privacy usage-description keys]; Network Traffic Content via Enterprise Secure Web Gateway / Proxy [DNS/HTTP(S) inspection or proxy transaction metadata where enterprise decryption/inspection is deployed]; Network Traffic Flow 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.
