# Chapter 1
### Chapter 1
### What is Predator-OS?
Predator is a GNU**/**Linux distribution**.** It is based on Debian stable**.** It is a complete operating system for Cybersecurity users and environments**.** Including software and systems for installation and management all based on the Linux kernel and free software**.** When I created Predator**-**OS**,** in 2021**,** I sought to have two principal features**.** First**,** performance and more security**.** It would also be a non**-**commercial distribution**.** I focused on the predator to be a **polymorphic security platform** for beginners and professional users **and** for academics and universities**.**
Remember that hackers are big people**.** Those who create valuable things and build the world**.** On the other side**,** there are crackers who only lose money**.** We have a lot of respect for real hackers**.** Those who usually hide in the shadows and whose names are rarely heard**.**
Predator**-**OS is a good choice for those who love security**.** This distribution has a great advantage over its competitors and has an easy and attractive user interface**.** Even if you are not familiar with Linux**,** you will feel good about this distribution**.** He is well**-**versed in the philosophy of open source and has applied this point in his development process**.** There are many open**-**source tools in this operating system for database analysis**.** Wireshark provides network packet analysis tools for analyzing information in networks**,** Bluetooth**,** wireless networks**,** databases**,** forensics**,** and more**.** Predator has been in development since 2021**.** This operating system supports a 64**-**bit platform**.** You can test Predator before installing it on live**.** It uses the PLASMA desktop by default and is released under the GPL general license**.**
### Why Predator-OS Linux?
You install Kali Linux**;** but after installing it**,** you realize that it is hardly usable**.** Despite the advanced Kali kernel**,** the network cards and mouse don**’**t work well after installation**,** and the heavy NVIDIA graphics card and GPU lack properly installed drivers**.** In Kali Live mode**,** it indicates that these advanced drivers have not reached the core yet**.**
This is especially true for those who are drawn to the security field**,** whether it**’**s a hobby**,** a hobby**,** or a line of work**.**
By observing these problems among users**,** we realized that we could guide users into the world of security by creating a more structured and user**-**friendly Linux distribution**.** Helping our community while simplifying all the complexities of Linux**.**
Predator**-**OS Linux provide a polymorphic security platform for systems and network administrators**,** security experts**,** digital forensics operations and cybersecurity engineers**.** It was focused on Pentesting**,** Ethical Hacking**,** Secure**,** Privacy**,** Hardened and Anonymized Linux**.**
The Predator**-**OS is available in edition security now**.** With other editions such as Desktop**,** IOT**,** mobile**,** Virtual machine**,** Raspberry Pi and Docker being released soon**.**
The default Desktop is PLASMA but the other Desktops such as KDE plasma**,** Mate**,** Gnome will be released soon**.** The system is designed to be familiar for the security expert and is easy to use for the new entry student**;** but it does not try to hide its internals, as other generalpurpose distributions try to do**.**

### Operates at 10 different modes:
The Predator**-**OS has 10 different modes and operates at the following modes for easy and faster access to all tools and it also is possible to change Linux Predator at**:** defensive**,** offensive**,** privacy**,** hardened**,** secured**,** settings and pretesting modes quickly**.**
### History
Predator**-**OS Linux started in 2021**,** initially it was supposed to be a privacy and anonymous Linux**.** It was due to the many problems users reported in the use of other Linux distributions in the field of security and the stopping of many distributions**,** this distribution was created**.**
At first**,** it was decided to make Predator**-**OS based on Debian**.** But due to having pre**-**installed security tools**;** as well as Debian being a rolling release**,** the distribution would have many updates and upgrades**.** And for this issue**,** I created the distribution in the fix release**,** so that updates can be done periodically**.** The best option for Debian stable distribution was the LTS version**,** which is known for its quality**,** stability**,** and wide selection of available software**.**
The first version of Predator**-**OS **(**version 1**.**0**)** was released nine months later after some issues and was based on the Debian stable Mini 18**.**04 at the time**.** In that first year of development**,** the focus was on security**,** privacy**,** anonymous distribution along with penetration testing tools**.**
After version 1**.**0**,** Predator**-**OS releases an update annually with new features and improved hardware support**.** I considered the PLASMA desktop for it because of its simplicity and speed**,** as well as better customization than other desktops**.** In version, 2 of the Predator**-**OS distribution**,** about 25 new features were released that switched from Debian stable 18**.**04 to 20**.**04**.**
In version 2, many things were considered**,** both in distribution optimization**,** turning**,** and tools**.**
I was trying to create a distribution with the best performance in several working modes in the field of security**,** which can cover all cases according to the extent of security**.** Finally**,** I created mods for the Predator**-**OS and it now works in 9 modes**.**
In version 2**.**5 of this distribution**,** it was released with 50 modifications and new features**.** Most of the focus of version 2**.**5 was on performance**.**
In version 3**,** the distribution will be towards artificial intelligence and the use of intelligent defense mechanisms in attack and defense mode**.**
### Based on Debian stable
Debian stable is open**-**source software that was developed by Canonical in October 2004**.** Debian stable is a Linux**-**based operating system**.** It is designed for computers**,** smartphones**,** and network servers**.** A UK based company called Canonical Ltd. develops the system**.** All the principles used to develop the Debian stable**.**
### LTS Release
It is a fixed**-**release distribution based on Debian stable mini 22**.**04**.**3 with the PLASMA desktop and kernel 5**.**18 LTS**.** A Polymorphic Security Platform that be able to run as live medium and you can install it on hard disk**.**
### Why LTS version?
LTS option allows users to stick with a particular version for an extended period of the software without worrying about the quality degrading due to technical issues or security vulnerabilities**.** LTS releases are more secure**,** stable**,** and hence reliable**.** In addition**,** all LTS releases get software updates and standard support for up to five years from the Canonical team**.** For servers**,** software development PCs**,** and other critical systems**,** it is highly recommended that you use the LTS version**.**
