<\/figure>\n\n\n\nFor me there were a couple of opportunities for some light reading. For example, while I know at a high level what Window Scale is or Maximum Segment Size (MSS), it was just that. High level. One of the questions I enjoyed was an open ended question asking to analyze the TCP handshake and explain the capabilities.<\/p>\n\n\n\n
I wasn’t quite sure what the answer would be (turned out my answer was spot on), but it led me to read a little more deeply into MSS<\/a>, Window Scale<\/a>, and even a bit deeper into what SACK <\/a>meant.<\/p>\n\n\n\n As I work through these labs and questions, I’m not simply trying to find the answer. I’m trying to understand<\/em> both the answer and how I got there. I have very clear objectives in my mind as I go through this learning exercise. I want to be able to open a PCAP and spot problems, identify potential issues, and as some might say – tell the story.<\/p>\n\n\n\n The questions in this lab, as the image above show, talked about proxy servers. For one of the questions I was instantly stumped. It asked about a .pac<\/em> file and what it was for. My notes \/ answer verbatim:<\/p>\n\n\n\n Something completely new to me. It’s always good to be learning new things.<\/p>\n\n\n\n The next lab and questions will deal with examining differences between HTTP and HTTPS. I’ve some familiarity with both of these at a high level, so again it will be fun to dive a little deeper into the weeds with a keen eye towards how I can take the information and use it later on.<\/p>\n","protected":false},"excerpt":{"rendered":" I’ll admit, Lab 1 took me longer than I’d hoped to complete, review, and write about.
