When operating a Linux OS, you need to use a shell — an interface that gives you access to the operating system’s services. Most Linux distributions use a graphic user interface (GUI) as their shell, mainly to provide ease of use for their users. That being said, it’s recommended to use a command-line interface (CLI) because it’s more powerful and effective. Tasks that require a multi-step process through GUI can be done in a matter of seconds by typing commands into the CLI. So if you’re considering using Linux, learning basic command lines will go a long way. These are basic Linux commands that will undoubtedly help you navigate through Linux.

Never root when you are a drunk. "sudo rm -rf" is command that could be detrimental to any linux newbie. Never use this command even when you are sober unless you want to wipe you machine. If you are into ditro hopping and interested in open source software this is a great funny design. Perfect gift for sysadmin, linux geeks, programmers and unix fans.

An inspirational design that features the Open Source OS - formerly known as Backtrack. A great gift for Linux lovers, geeks, programmers, hackers, tech lovers,

Network Mapped (Nmap) is a network scanning and host detection tool that is very useful during several steps of penetration testing. Nmap is not limited to merely gathering information and enumeration, but it is also powerful utility that can be used as a vulnerability detector or a security scanner. So Nmap is a multipurpose tool, and it can be run on many different operating systems including Windows, Linux, BSD, and Mac.

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds.

A computer programmer creates the code for software applications and operating systems. After a software developer designs a computer program, the programmer writes code that converts that design into a set of instructions a computer can follow. They test the program to look for errors and then rewrite it until it is error-free. The programmer continues to evaluate programs that are in use, making updates and adjustments as needed.

Linux CLI Sleep command is used to delay for a fixed amount of time during the execution of any script. When the coder needs to pause the execution of any command for the particular purpose then this command is used with the particular time value. You can set the delay amount by seconds, minutes, hours and days.

Zero or one?

A distributed denial-of-service (DDoS) attack is a malicious attempt to disrupt normal traffic of a targeted server, service or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic. DDoS attacks achieve effectiveness by utilizing multiple compromised computer systems as sources of attack traffic. Exploited machines can include computers and other networked resources such as IoT devices. From a high level, a DDoS attack is like a traffic jam clogging up with highway, preventing regular traffic from arriving at its desired destination.

The Metasploit Project is a computer security project that provides information about security vulnerabilities and aids in penetration testing and IDS signature development. It is owned by Boston, Massachusetts-based security company Rapid7. Its best-known sub-project is the open-source Metasploit Framework, a tool for developing and executing exploit code against a remote target machine. Other important sub-projects include the Opcode Database, shellcode archive and related research. The Metasploit Project includes anti-forensic and evasion tools, some of which are built into the Metasploit Framework. Metasploit is pre-installed in the Kali Linux operating system.

a 404 error page is a web page on a website which primarily shows visitors a warning message and explains that visitors just try to access web pages don’t exist at the moment of access. Malware distributors, hackers, and phishing scammers are continuing to use the practice of hiding login forms for their web shells in fake HTTP error documents. These pages pretend to be HTTP errors such as 404 Not Found or Forbidden, while in reality they are login pages that allow an attacker to access a web shell to issue commands on the server.

The terms “deep web” and “dark web” are sometimes used interchangeably, but they are not the same. Deep web refers to anything on the internet that is not indexed by and, therefore, accessible via a search engine like Google. Deep web content includes anything behind a paywall or requires sign-in credentials. It also includes any content that its owners have blocked web crawlers from indexing. Medical records, fee-based content, membership websites, and confidential corporate web pages are just a few examples of what makes up the deep web. Estimates place the size of the deep web at between 96% and 99% of the internet. Only a tiny portion of the internet is accessible through a standard web browser—generally known as the “clear web”.

whoami command is used both in Unix Operating System and as well as in Windows Operating System. It is basically the concatenation of the strings “who”,”am”,”i” as whoami. It displays the username of the current user when this command is invoked. It is similar as running the id command with the options -un.

Red team are like ninjas, they attack with their stealthy techniques to avoid being detected and prove there is a vulnerability before an actual attacker discovers it. Perfect design for CTF game.

A funny design about the fact that cybersecurity professionals need to be somewhat crazy to love their job.

The Spain flag design of the Cybersecurity Red Team in badge style. Ideal for your peers working with you in the same cyber security group. Let's prove to the Blue Team that their detections and security measures are useless!

Before Kali Linux became that popular, it was known as Backtrack Linux and this distribution was renamed to kali from 2013.
