Understanding the differences between modes was the hardest part of this lab for me, as I would often use commands in the wrong mode and have trouble fixing my mistakes.<\/p>\n\n\n\n

In this Lab, I had trouble understanding some functions\/commands and what they did; for example, in Task B, step 12, I couldn’t figure out why the user wouldn’t delete.<\/p>\n\n\n\n

I found this lab enjoyable, however, I ran into trouble when I discovered that the Rockyou text file was not included with my personal Linux version. As a result, I had to switch to the school’s version of Linux to complete the lab.<\/p>\n\n\n\n

I found this Lab to be pretty challenging, especially when I reached Task C. The file permissions did not behave as i thought they would; I later discovered that I had used the wrong command, and it turned out to be an easy fix.<\/p>\n\n\n\n
<\/object>Lab-6-File-Permission-Ava<\/a> Download<\/a><\/div>\n\n\n\nIn Lab 7, we worked with local storage systems. We used commands to check the file system and create virtual disks, partitions, and filesystems. I didn’t run into much trouble during this lab, but the most challenging aspect for me was finding and highlighting the differences when making changes.<\/p>\n\n\n\n

I enjoyed this lab because it combined skills I’ve learned previously, like programming in Python\/Java and working with the vi editor. I did have some formatting issues when the tasks would run, however, they were easily fixable.<\/p>\n\n\n\n
<\/object>Lab-8-Shell-Scripting-Ava<\/a> Download<\/a><\/div>\n\n\n\nIn Lab 9, we used shell scripting as a foundation to explore task automation using tools like crontab. This lab was more difficult for me than the previous one because it had many steps and several new commands, and I faced more challenges when resolving errors.<\/p>\n\n\n\n

I enjoyed this lab because the values were easy to figure out once I knew the pattern. The most challenging part of this lab for me was discovering how to get one value from another.<\/p>\n\n\n\n

I encountered multiple issues because my personal Linux did not include the necessary tools. As a result, I switched back to the school\u2019s Linux system to complete the lab, however, I could not change the network connection from NAT to bridged in this Linux system. <\/p>\n\n\n\n

The course was engaging, challenging, and reinforced principles from previous courses, giving me confidence in my ability to apply essential cybersecurity skills moving forward.<\/p>\n","protected":false},"excerpt":{"rendered":"
