What is CTF?

CTF, or Capture The Flag, is a type of cybersecurity competition where participants solve challenges to find “flags” (specific pieces of text) hidden within systems, files, or code. These challenges test skills in areas like cryptography, web security, reverse engineering, forensics, and more. CTFs are popular in the cybersecurity community and are used for learning, practice, and fun.

Types of CTFs

1. Jeopardy-Style

   • Participants solve challenges organized into categories (e.g., cryptography, forensics, etc.).
   • Each solved challenge reveals a flag, earning points.
   • Examples: Decoding encrypted messages, analyzing memory dumps, or identifying vulnerabilities.

2. Attack-Defense

When you first jump into Linux, one of the first things you’ll encounter is its file system. Unlike Windows, which uses drive letters like C:, Linux organizes everything under a single root directory (/). This organization might seem a bit daunting at first, but understanding it is key to navigating your system, troubleshooting problems, and managing files effectively. So, let’s break down the Linux file system hierarchy in a more approachable, human way, so you can start using it like a pro.

Linux Networking Essentials: From IP Addresses to Firewalls (In-Depth Guide)

Networking in Linux is an essential skill for anyone working with the operating system. It forms the backbone of all communication between systems, whether it’s on the internet or within a local network. In this detailed guide, we’ll dive deep into essential networking concepts, from understanding IP addresses and subnetting to configuring IPs and setting up firewalls.

1. What is Networking on Linux?

Networking on Linux refers to the process of connecting your Linux system to other devices and systems via different network interfaces. This could involve connecting to the internet, setting up local networks, managing network configurations, or securing your system with firewalls. Linux provides a flexible and powerful environment for managing these tasks.

Docker on Linux and Windows: Setting Up and Running Your First Container with Real-Life Use Case

Docker has revolutionized how we deploy and manage applications, offering a consistent environment across various platforms. By creating containers, Docker allows developers and sysadmins to package their applications with all the dependencies they need, ensuring they run smoothly regardless of the environment. Whether you’re on Linux or Windows, setting up Docker and understanding its core concepts will make your life easier. In this blog, we’ll not only go through the installation process on both Linux and Windows but also dive into a real-life use case—deploying a web application using Docker.
