Mobile Operating Systems Architecture

Understanding mobile OS architecture is fundamental to forensic analysis:

iOS Architecture:

  • Secure Boot Chain: Ensures system integrity from startup
  • Secure Enclave: Hardware-based key storage and encryption
  • App Sandboxing: Isolates applications from each other
  • File System: APFS (Apple File System) with native encryption
  • Keychain: Encrypted credential storage

Android Architecture:

  • Linux Kernel: Modified Linux base
  • Hardware Abstraction Layer: Device-specific implementations
  • Android Runtime: App execution environment
  • Application Framework: System services and APIs
  • File Systems: ext4, F2FS with optional encryption
