Linux Systems for Cybersecurity

Linux Systems for Cybersecurity was one of the first foundational courses I took at Old Dominion University. This course was an introduction to Linux while focusing on its cybersecurity capabilities. We started with learning basic commands and built up to system administration and network configuration. The assignment I chose to highlight, Network Configurations, is one of the later assignments completed during the course. In this assignment we configure two Linux virtual machines. One virtual machine is set up as a client and the other as an internet gateway. 

While working through this assignment, and the course overall, I gained valuable technical skills. Linux systems are used widely in the IT world and even more so for cybersecurity. Therefore it is important that I have an understanding of how these operating systems are used. This course built a foundation of knowledge for Linux operating systems. We learned everything from the command line, to file structure, to permissions, to configuring firewalls and routing tables. It is my hope that I would be able to use this knowledge in a systems administration/security position in the future. 

From my time taking Linux Systems for Cybersecurity I have several lab reports. These reports document my learning experience from basic Linux commands to network configurations. The lab report I chose to upload was the Network Administration assignment. In this assignment we had to set up two Linux virtual machines. One was configured as the client and the other was configured as an internet gateway. Both of the virtual machines were connected to the same internal network. I then had to add entries into both machines iptables (a command line firewall). First to direct the client to the gateway machine. Then on the gateway machine I added entries to forward traffic to and from the internet, allowing connection to the internet from the client machine.
