This is an important skill in cybersecurity as many critical infrastructures run on Linux-based environments. It is important to know how these systems work to be able to navigate systems and be able to perform troubleshooting or analysis on what is going on in these infrastructures. This knowledge provides a strong base for working in real world security tasks like monitoring and investigating systems.

Password Cracking

This artifact is from my CYSE270: Linux System for Cybersecurity course. The artifact demonstrates my ability to crack simple passwords finding which passwords are too weak and which passwords are strong enough to withstand brute force attacks. This will help me to come up with password requirements when analyzing policies in the future.

File Permissions

This artifact is also from my CYSE270: Linux System for Cybersecurity course. This artifact demonstrates my ability to be able to give certain people certain permissions within the Linux based system. This will help me in the future with access control in the workplace. For example, I will be able to give an employee only read permissions, an admin both read and write permissions, and a random person off the street no permissions.

Network Analysis and Firewall Configuration

Lastly, This artifact is also from my CYSE301: Cyber Techniques and Operations course. This artifact demonstrates my ability to analyze traffic using Wireshark. It also demonstrated my ability to view a firewall and make rules to either block or allow traffic from certain IP addresses preventing possible reconnaissance from attackers. I also explain in my assignment how I completed all the tasks showing my understanding of Linux systems and the firewalls protecting it.
