LiveUSB and SecureKOS

This page contains content about Linux Debian distro, live USB and Secure-K OS. They are bases of SyncOS development.

You can find some of the contents are from the following web sources:

Linux Debian Distro

Debian is one of the oldest operating systems based on the Linux kernel. The Debian Stable branch is the most popular Linux edition for personal computers and servers. Debian is also the basis for many other Linux distributions, most notably Ubuntu.

Debian is famous for its reliability and security.

Debian has access to online repositories that contain over 51,000 packages. Debian officially contains only free software, but non-free software can be downloaded and installed from the Debian repositories. Debian includes popular free programs such as LibreOffice, Firefox web browser, Evolution mail, K3b disc burner, VLC media player, GIMP image editor, and Evince document viewer, etc.

SyncOS and Secure-k OS are Debian derivatives.

LiveCD and LiveUSB

Most Linux distributions are available in live CD, live DVD or live USB format.

A live CD (also live DVD, live disc, or live operating system) is a complete bootable computer installation including operating system which runs directly from a CD-ROM or similar storage device into a computer's memory, rather than loading from a hard disk drive. A live CD allows users to run an operating system for any purpose without installing it or making any changes to the computer's configuration. Live CDs can run on a computer without secondary storage, such as a hard disk drive, or with a corrupted hard disk drive or file system, allowing data recovery.

As CD and DVD drives have been steadily phased-out, live CDs have become less popular, being replaced by live USBs.

A live USB is a USB flash drive or external hard disk drive containing a full operating system that can be booted. They are the evolutionary next step after live CDs, but with the added benefit of writable storage, allowing customizations to the booted operating system. Live USBs can be used in embedded systems for system administration, data recovery, or test driving, and can persistently save settings and install software packages on the USB device.

SyncOS adopt the live USB format due to its following advantages:

Customer can use their existing Windows (or other OS) PC without re-install the new OS. Use SyncOS live USB won't have impact on working PC's own Windows (or other OS).
It can be fully encrypted and protected. Even if the USB drive is falling into other person's hand, it's hard to decipher and get the data out.
Customer carries it more easily. Customer can attach it to his key chain, bring it everywhere and anytime, without left critical document behind him. This is especially important when you are in frequent travels.
Its work leaves no trace once PC power off, as it is working on memory, not hard drive.
OS can keep pure data integrity. You won't fear any virus and spamware on your live USB OS. You also won't fear your live USB OS will deteriorate during its life time. This is due to its OS file system is read only, which is similar to live CD/DVD.

Use live USB drive as OS format has some limitations.

Data loading from USB drive is normally slower than loading from hard disk. To improve performance, selected thumb drive should be USB-3 up with faster read/write speed.
The work PC needs to support boot from USB drive.

SecureKOS

Secure-K OS is an advanced Debian Stretch Linux-based live USB operating system built for security: user and system data are saved encrypted within the USB drive, so the system can be used as a clean and safe environment for your on-line security-critical activities. Secure-K features the GNOME Shell desktop environment and is developed by the Mon-K organization.

SyncOS is forked from Secure-K OS. For more detailed information about Secure-K OS, please refer to github Secure-K OS project.
