Learning Log for Information Systems Security: Week 3 and 4 (Organizational Security)

In the past 2 weeks, all we think about is the preparation for midterm paper mainly the related literature connected to our topic which is the Bitcoin. At first, I really don’t want to participate with my groups due to other activities that I am attending but because of perseverance, I had done my part when I found time for doing it. Sometimes the things you do might be boring to you but, looking at the bright side lets you see the brighter side or the positive side. Coincide with the preparation of the paper is our discussion, which is the Organizational Security. For the Week 3, I have learned that the security hierarchy are based on the organization’s priority, policies and ethics. The Operational Model are planning, implementing, monitoring, and evaluating which is a never ending cycle if maintenance for the security will be conducted. We discussed much policies in an organization and the thing that I am fascinated about is that there are some policies wherein power in the company is not an option, meaning equality was established in this policy for example, IUP or Internet Usage Policy, which is the connectivity of all the members in the organization in the internet. We also discussed the 3 types of Model, Sir JP said that there are 30 Model, but we focused for 3 models only because this are most commonly used in the organization. Let us start with Bell La Padula Model, with a misconception of Bella Padilla based on first time encounter, that is a confidentiality model that has the rules of simple security rule that doesn’t allow to read security higher or different from your department; Star property that cannot write security if lower or different from your department. Next is Biba Model which is the integrity model that has a simple integrity rule that is the contrast of Bell La Padula and also the star property. Last is the Clark-Wilson Model is an integrity model and it uses a medium for its security. This discussions are all done for the Week 3 because Week 4 was dismissed due to different kinds of events. For Week 4 first meeting, It is the end of Ramadan and Muslims had to celebrate it despite of the war in Marawi City. Second meeting, Sir JP told has that his not feeling well and unable to tutelage us for this period, so he cancelled that session, this really broke my heart. Take Care and Get Well Soon Sir JP!
