Automatic security updates for Debian based systems

unattend-upgrades is a debian package providing automatic security upgrades.

To use it, just install unattended-upgrades, modify /etc/apt/apt.conf.d/50unattended-upgrades to your needs like: 

Unattended-Upgrade::Allowed-Origins { "Debian stable"; };
To automatically and unattended install security updates you also have to set 
APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Unattended-Upgrade "1";
in /etc/apt/apt.conf or in a file located in /etc/apt/apt.conf.d/ (I use /etc/apt/apt.conf.d/60security)
For further details have a look at /usr/share/doc/unattended-upgrades/README or https://wiki.ubuntu.com/AutomaticUpdates

Just setup unattended-upgrades and life becomes more easy as you dont have to remember to upgrade each of your machines.
