Android primarily supports 802.1X over Wi-Fi. Ethernet 802.1X is not exposed in stock Android settings, but it can be enabled in AOSP with additional integration at the framework and HAL level.

It provides a robust security mechanism to allow only authorized devices access to the wired network, helping prevent unauthorized network access, improve enterprise security, and comply with regulatory standards.

Common EAP methods that can be enabled in Android Ethernet 802.1X include:

• EAP-TLS (certificate-based)
• PEAP (with MSCHAPv2)
• EAP-TTLS

• Enterprise LANs where wired ports require authentication.
• Kiosks, POS systems, and digital signage that connect over Ethernet.
• Automotive (AAOS) or Industrial Android environments.

Yes. Just like Wi-Fi 802.1X, you can use CA certificates, client certificates, and private keys for TLS-based authentication. These are usually managed via the Android Keystore system.

• Set up a RADIUS server (e.g., FreeRADIUS) with supported EAP methods.
• Configure a switch with 802.1X authentication enabled.
• Connect the AOSP device via Ethernet and verify authentication success.

Certificates must be installed on the device manually or via Mobile Device Management (MDM) platforms. Client certificates are required for EAP-TLS, while CA certificates are needed to validate the authentication server. Certificate formats and proper installation are crucial for successful authentication.

Yes, but only if the OEM or AOSP build exposes DevicePolicyManager APIs for Ethernet. Out-of-the-box Android generally does not, so it may require custom device management extensions.

• Switches and access points that support 802.1X protocol.
• RADIUS server to handle authentication requests.
• Certificate Authority to issue server and client certificates.
• Proper network configuration including port setup.

Yes, Android supports 802.1X on Wi-Fi natively. Ethernet 802.1X support varies by device and often requires additional vendor support or custom modifications to Android.

SSH server support is often required for:

• Remote debugging and development
• Secure remote file transfer (SCP/SFTP)
• Enterprise device management and automation
• Easier system service access compared to ADB-only workflows

• Dropbear: Lightweight, suitable for embedded systems and resource-constrained devices.
• OpenSSH: Feature-rich and widely used in Linux distributions, but heavier than Dropbear.

You typically:

1. Add the SSH server source (e.g., Dropbear) to your AOSP build tree.
2. Configure Android.mk or Android.bp to include the server in your system image.
3. Update init.rc scripts to start the SSH service at boot.
4. Set proper SELinux policies to allow SSHD to run.

It can be secure if:

• You disable password-based login and use only key-based authentication.
• You configure proper SELinux rules.
• You restrict SSH to trusted interfaces only.
• You keep the SSH server updated with security patches.

• Password-based authentication (not recommended in production).
• Public key authentication (preferred for security).

Not entirely.

• Dropbear has low overhead and is usually preferred for performance reasons.
• OpenSSH consumes more resources but offers broader compatibility and features.

Yes. By default, SELinux may block SSH server processes. You need to create and load a custom SELinux policy module that permits SSHD to bind to network ports and access user directories.

Yes, with proper scripting, SSH can help automate OTA updates, provisioning, and system maintenance, especially in enterprise or IoT deployments.
