Learning Log 6

Learning how to use pfSense gave me an idea to use it for my home internet, especially, when I'd have my future kids. Blocking websites that are not intended for minors is a good way to hide content that are only for adults. For me, it is another way to avoid phishing websites and etc.

In our lecture, the topic physical security was being taught. It actually gave me a new perspective on how buildings handle their security. Like what kind of door should be used for fire exits which should be made of light timber and knowing that there are different kinds of water sprinklers that best fit a situation. There are numerous ways on how to secure a building but standards should be followed at least. No steel doors for fire exits, please.

In another lecture, it was like a review of our previous subject. We should take note of the broadcast domain and the collision domain of each network device (Hub, switch, and router). Setting up an environment for example, a company, needs firewalls for security. The firewalls are packet filtering, packet inspection, and the application firewall.

Below is the cleanest picture you'd ever see.

Learning Log 1

We were given a group activity that tested our knowledge in security. The one that was given to us was a grocery store with only two guards as their security, no CCTV or whatsoever, and they rely with the "honesty system" which lead them to lose merchandise that cost 10K pesos a month. That loss has been happening for 6 months. My group and I thought about solutions that cost zero cash so every recommendations are more on adjusting how the employees should work. I thought about the whistleblowing system where person raises concern about a wrong doing when he/she sees one. During our presentation, our professor said it was creative of us to put it as our solution, the whistleblowing system. He even said that companies would be happy to us since our solutions are cost-free. All in all the presentation went well. In the last lesson, I've come to realize that not all top privileged users are allowed to access all the resources. Mandatory Access Control (MAC) having labe...

Learning Log 5

We were given an exercise about the RSA Algorithm and the Diffie Hellman Algorithm. In the RSA Algorithm, I found a way to find the value of the  d  variable that is easier than guessing. It is by using the Extended Euclidean algorithm. In Diffie Hellman, I believe I haven't found an easier way to find the values of the variables. All in all, I learned how to understand and use these algorithms. I am excited to learn more algorithms for security.

I realized that laws can either aid you or jail you from your doings. Each law has their own category making them somewhat unique from each other. The laws discussed which are statutory, administrative, common, civil, criminal. I learned that a court would follow the precedent cases to make a decision. For example, the court decides to give lethal injection to a murderer. The next case would have a large chance of giving a lethal injection to a murderer since it has been done before. This is called the common law and it could replace statutory laws. Privacy, a subjective term in every individual. Privacy can depend on one's culture that is why the thought of privacy is complex. Laws of privacy can even contradict to others. A law may aid you, another may jail you.
