- Network Security: Android incorporates features like DNS over TLS, TLS by default, and enhanced VPN services to secure network communications.

- Application Security: Google Play Protect and other services work to prevent threats and abuse by identifying potentially harmful applications.

- Data Protection: Encryption methods, including Adiantum for low-power devices, are detailed along with backup encryption strategies.

- Hardware-backed Security: The document discusses hardware-backed security features like Trusted Execution Environment, Verified Boot, and Android Keystore System, among others.
