ATI-OS

Minimalistic and secure operating system

Licensing: See the LICENSE file

Features:

I. Preparation scripts (Linux only)

• Small size
• Automation of the most processess related with getting, preparing, compiling and configuration

II. Final product (Linux disribution):

1. Minimal core - The system base (core) itself contain only files required to start-up and run the system
2. Enchanced security - The system will be defaultly hardened and isolated to provide maximal possible protection. The hardenings include among others:

• kernel hardening
• minimal permissons for the core components of the system
• total isolation from "outside world" (all connections will be done thru secure tunnels)
• installed and configured security software
• multiple security layers

3. Small footprint - In oposite to other Linux distributions, except the security software, there won't be neither a GUI, nor other software preinstalled
4. Full customization - The administrators may freely customize the system (by installing the GUI and software at choice) according to the needs

Requirments:

Scripts:

I. 64-bit Debian based Linux distribution

II. All required packages needed to get, compile and prepare the Linux image file. Bellow, are few of them:

a) Build environment containing among others:

• build-essentials (install's allmost all software required for the compilation process)

• bison++

• CMake

• gcc

• c++

• libtool

• python3

• sqyashfs

• libssl-dev

• autotools (autoconf, automake)

• m4

b) Dependencies required by the third-patry software required to compile the sources

Final product - portable (live) system

IMPORTANT

1. The USB stick need to meet following criteria:

• must be cleaned using the wipe command to prevent any potential leftovers from previous data and potential malware

• must have a GPT partition table

• the partition need to be set bootable

2. The BIOS/UEFI need either to be set to run from USB before the hard drive or be run from a boot menu

3. You have propper tools to "burn" the Linux image to the USB stick

Distribution preparation using included scripts

1. Get the content of the repository (one of):

a) using git clone (remember to use the --recrusive and --recrusive-modules options)

b) Download the archive from the repository and then extract it on your drive

From now, the folder to with the repository got clobed/extracted will be refered as the "project dir"

2. In the project dir enter the code sub-folder

3. ensure that the scripts are executable (command: chmod -v +x *.sh)

4. run the prepare.sh script

5. After the script finishes (assuming that it wasn't interrupted due an error), return to the project dir and then enter the dist sub-folder. Inside should be a Linux image that need to become "burned" into a USB stick. It can become also used in Virtual Machines
