Eric Ilmberger CNT52 Network Fundamentals I did a little more research on symmetrical and asymmetrical encryption because it wasn't described well in testout. Symmetrical encryption uses a shared key that when entered allows the user to read the data. Symmetrical keys are used in SSH to secure the entire connection to prevent password snooping. Asymmetrical encryption uses two different keys, a private key and a public key. Either key can be used to encrypt data but the opp

Eric Ilmberger CNT 52 As China hosts the largest population on the planet, it only makes sense that they would need more IP addresses to cater to all those people. “’China is the world’s largest number of internet users, but there are only 0.45 IPv4 addresses per person’” According to the Washington Post, America has 5 IP addresses per person. This puts china at a massive disadvantage when it comes to networking infrastructure. The new plan they are adopting will push to have

For many years people have been using aluminum foil to help enhance and extend the range of their Wi-Fi networks. The question we may have is well how well would it perform? Will it make a significant or noticeable difference? What do you think? Here are a few videos that may shed some light on these old techniques submitted by student Mohamad Malikzada. Boost WiFi Signal range through walls and get better Internet connection using aluminum foil disk How much can Aluminum

Spoofing Fully Qualified Domain Names How can you spoof a FQDN? John Hohn covers the history of DNS and name registry to demonstrate a flaw/feature that allows for the spoofing of fully qualified domain names. Learn how a Puny code vulnerability can be used by hackers to redirect unsuspecting browsers to malicious or spoofed sites. #PunyCode #DNS #DomainName #FQDN #Cybersecurity #Vulnerability #TipsandTricks #Network #Network #NetworkTrafficAnalysis #CNT52

A common tool for monitoring network traffic that is taught in classes is Wireshark. In part, because it is freely available. However, there are a number of other tools that can be used to capture and analyze network traffic. When compared with other tools you will often find them to be easier to use and more visually useful. OmniPeak with the Savvius devices can help you do protocol and network traffic analyzation. This series of videos will do a comparison of the two p
