Privatix Live-System is a portable encrypted operating system designed to be run directly from a USB flash drive or an external hard drive. This allows the user to safely edit and carry along sensitive data for encrypted communication and anonymous Web surfing. It is based on Debian GNU/Linux.
UsbCryptFormat is a graphical user interface (GUI) for the encryption of USB flash drives or external hard drives. It allows the user to reformat a USB flash drive, an SD card, or an external hard drive with an encrypted filesystem very easily and without the danger of destroying data on an internal hard drive because of incautious handling of device names. So it is usable even for a layperson.
Buck-Security is a security scanner for Debian and Ubuntu Linux. It helps you to harden your system by running some important security checks. For example, it finds world-writable files and directories, setuid and setgid programs, superuser accounts, and installed attack tool packages. It also checks your umask and checks if the sticky bit is set for /tmp, among other checks.
