Chapter 10 Summary:

After reading chapter 10 I saw several familiar terms. Metadata is data about data, this is a definition that I had to learn during my studies for the CompTIA Sec+ exam. Data aggregation is another term that I came across while I was reading chapter 10 which reminded me of what a SIEM is. A SIEM is a security information event manager and what it does is it basically aggregates logs from several different devices. Basically, it watches for suspicious activity or security threats on the network, alerts the security team, and helps them respond quickly to protect the system. It does this by organizing all the security information in one place, making it easier to find problems and fix them. I also came across the term “PII” which is a type of sensitive information that I am familiar with. One thing that I was very surprised to find was Decomposition. I didn't understand what this meant at first but my understanding of it is that it means breaking down a complex problem into smaller, more manageable parts. The concept itself sounds quite simple, but my math skills aren’t the best and so actually putting this concept into practice mathematically would prove to be challenging for me. I will research this further to become more familiar with it.
