Hands-On Cybersecurity and Ethical Hacking – Full Course

Kali Linux specialized penetration testing operating system

Kali Linux is specifically built for penetration testing, security research, and forensic analysis, featuring over 300 pre-installed hacking and security tools.

Course targets absolute beginners with zero prerequisites

The curriculum is designed for individuals with no prior ethical hacking experience, teaching everything from Linux command line basics to foundational wireless security concepts.

Basic system orientation and user identification commands

Essential navigation includes `pwd` for current location, `whoami` for user identification, `hostname` for system name, and `clear` for terminal cleanup, with the `$` prompt indicating regular user status as opposed to root access.

Advanced directory traversal using cd command

The `cd` command supports navigation via specific paths, `..` to traverse up one directory level, `-` to return to previous working directories, and standalone execution to jump directly to the home directory.

LS command variations for comprehensive file listing

The `ls` command provides multiple options including `-a` to reveal hidden files (those starting with a dot), `-l` for detailed permissions and metadata, and `-h` to display file sizes in human-readable KB/MB/GB formats.

Nano text editor for terminal-based file manipulation

Nano functions as the primary text editor where Ctrl+O saves files, Ctrl+X exits the application, and specifying filenames at launch (e.g., `nano filename.txt`) streamlines the creation process.

Cat command for viewing and creating files

The `cat` command enables viewing file contents with optional line numbers using the `-n` flag, concatenating multiple files, and creating new files through output redirection with the `>` operator.
