This week our lecture was on networks while our quiz was
still on recursion, the quiz was too simple that I thought I was writing down
the wrong answers. While talking about token networks the interactive example
was a good method to illustrate how it works.
While looking at the various different networks we looked at
the security functions / trust levels that each network brought with them. Prof
Heap also showed us how he could access files from the cdf server and see what
other cdf had opened on their screens. This led me to try to find out how
secure my own home network & my cell phone hotspot are. Since my wifi
network at home is a bus network I found that I could download a “sniffer”
program and intercept packets of data that are being transferred to other
computers. I could even intercept a voIP call if it encrypted a certain way. As
I got more curious about encryption and security I read about keyloggers and
file encryption.
After doing some basic research I logged onto “Connection
Hub,” a router managing software that comes with Bell Internet service. From
the online site I can now view everything that is connected to the network both
through Ethernet and through WiFi. I can also change the router password and
the type of encryption used.
Test 2 is next Wednesday. Time to study!
