SecDroid is an Android app that secures your devices against several intrusion methods.
SecDroid hardens the android kernel by disable certain binaries that have internet access or can be used as an attack vector.
Some of the functions which are disabled are SSH, SSHD, Telnet NC (net cat), Ping, PM (Package Manager – Can’t install apps via CLI/ADB), ADBD (ADB is disabled until reboot) etc. ADB and PM are both disabled to help prevent an attacker from being able to install apps via the command line or adb shell. Both of these are potential attack vectors. You can install apps via the play store and GUI.
