Part 1
The first step is to install Wireshark. My shortcut got deleted so I decided to download it again from class
resources. Next I have to accept the license agreement:

The device will need to reboot. I chose to do the reboot now option.
Step 2 is to find a public, not secure Wi-Fi network to link my laptop to.
Now that I have connected to a public not secure Wi-Fi I will attempt to visit some unsecured websites:

What I noticed immediately was port 137 on the unsecure website capture is utilized by NetBIOS
which means all my files and printer information. I also observed that there were significantly more packets delivered on the unsecure Wi-Fi and websites. I then analyzed a few of the highlighted red ones and noticed that they all came from the same SRC port (443). 2.
While most wireless networks offer some sense of security, it is not possible for a network to defend against all attacks and threats. Some recommendations to add a layer of security include turning off vulnerable ports, enabling firewall rules, and clearly defining the right access points. Another good idea is to add encryption when dealing with sensitive data.
3.
The WLAN would be the method that I would recommend limiting most out of that list since sensitive data is more susceptible to being leaked. While a WLAN may be easier to install and communicate with, the government can also limit the flow of signals with bandwidth and unauthorized users may be able to see the communications (Pulkitagarwal03pulkit, 2022)
