I have several Android devices in a local network. (Android Set Top Boxes from Geniatech, running 4.2 Jelly-Bean) If these boxes have problems or need debugging, I simply connect to them via
adb connect ip-address
there I have full access to the (rooted) devices.
Unfortunately everybody in the network has this possibility. I understand that it is the responsibility of the network admin, to protect it against hackers and stuff, but I would like to add additional security. So my question is:
Can I somehow protect the adb-connection to the Android with a password? (or a Certificate or something) Or does anybody of you know alternatives?
ADB must remain open, so I can access the devices from the network, e.g. to directly make apk-updates, or read the logfiles.
