Power Security prevents the shutdown of an iDevice, it represents a perfect security measure for your terminals

  Power Security is a tweak released during this evening in Cydia, and with its help we can implement additional protection measures for our own iDevices. More precisely, the tweak gives us the possibility to set a security code or password that must be entered when someone tries to lock our iDevice, including when someone tries to reset by pressing the buttons simultaneously Home + Lock. The idea is extremely good and does not allow users to cancel the action of entering the password, this measure practically forcing the entry of that password to perform the shutdown/reset, otherwise the terminal will work until it runs out of power.

For iPhone, iPod and iPad on iOS 6.c This tweak makes it so you have to enter a password every time you try to power off your device. This and Lockdown Pro put together create the ultimate security available giving you better peace of mind. cConfigure options from Settings.

  Power Security is available at the price of $1 in the repo BigBoss al Cydia.
