Comprehensive Linux and Security Lab Series

Overview

In a series of lab activities, I focused on enhancing my practical skills in Linux, covering file and directory management, text editing, system setup, and configuring authorization. These labs have helped in developing my capabilities as a security analyst, using Linux-based systems.

Lab Details and Skills Acquired

1. Linux File and Directory Management:

   • Practiced pwd for displaying the current working directory.
   • Used ls to list directory contents and ls -l for detailed file and directory information.
   • Created a Linux Tails bootable USB and installed Kali Linux on a wiped laptop.
   • Set up Kali Linux as a VM on a Windows 11 desktop using virtualBox, this includes making BIOS changes to allow CPU virtualization.

2. Directory Structure Modification and Text Editing:

   • mkdir logs to create a new logs subdirectory in /home/analyst.
   • rmdir temp to remove the temp subdirectory.
   • mv Q3patches.txt /home/analyst/reports/ to move files between directories.
   • rm tempnotes.txt for deleting unnecessary files.
   • Used nano to edit tasks.txt, adding notes about changes made.

3. Configuring Authorization and Permission Management:

   • Navigated using cd to change directories and check file permissions.
   • Employed chmod for modifying file and directory permissions.
   • Executed ls -la to check hidden files and their permissions.
   • Altered permissions using chmod g-r and chmod o-w to limit file access.

Comprehensive Skill Development

• Command Line Proficiency: Demonstrated command line efficiency in Linux, using a variety of commands for file system navigation and management.
• System Configuration and Setup: Gained practical experience in system configuration, including Linux installations and VM setups.
• Text Editing: Proficient in using text editors like nano for editing files, crucial for documentation and script editing.
• Security Focus in System Management: Developed a deep understanding of file permissions in Linux, reinforcing security and authorization concepts.

Conclusion

These lab experiences have significantly contributed to my proficiency in Linux and cybersecurity. I've developed a strong foundation in system management, security practices, and efficient handling of Linux-based systems, making me well-equipped for roles in cybersecurity and system administration.
