For the last two weeks I learned a lot of different lessons in Opesys. First is the Security Architectural Models which are Bella La Padula Model, Biba Model and Clark Wilson Model. I was quite confused because I wasn't able to understand it at first but at the end I already did, Yipee! I can say that when you will do it, you should really focus and put your mind in to it. You should also know the ranking of the Topsecret, Secret, Confidential and Public.

The main thing that I learned for the past three weeks is how to code and make a new user in Linux. I also learned how to put it in a group, how to create a group, how to put a password on the user that I made and I also learned how to change the access of a specific group, if they can write, read or both. It is really cool and fun as well, as long as you know the code you can add users as long as you want and you can also change their accessibility because that is your account or your user.

On our last meeting, we had a quiz and it's sad to say that I did not passed but it is okay because there is always a next time:)
