Today I realized there really is a lot more involved in Network Security then I had originally imagined. My paper covered machine-learning for anomaly detection, while we also discussed spam filtering, botnets (and how to attack them), improving DNS in order to track malicious activity, and even outsourcing network management in an attempt to improve network security (which reminds me too much of the movie "The Net" to sound like a safe and viable solution).
Maybe I hadn't realized that there was such a wide variety because I haven't researched much in this area, or maybe because I haven't been exposed to all the different ways that "bad guys" try and attack a network, but this topic has been a really eye-opening experience. I mean Hollywood glamorizes hacking all the time, but these papers discuss serious threats that could have serious ramifications. Seeing a real-life perspective of cyber-terrorism is interesting and it starts to make sense why it has become more of a cat and mouse game.
Some of the papers had really intuitive ideas to deal with attackers, and even tutorial papers like the ones I read play an important part. As my professor stated in class, tutorial papers do a great job at focusing the field in the right direction, so that students working on their Master's can understand how to proceed if they are new to the area and can help the community as a whole fight the "bad guys."

Wireless Networking
For our networking research group and our upcoming lectures in our networking class, we are looking at wireless networks. The only work I've done with wireless networks in my life is setting up a wireless router in my home so that I can link several laptops, smartphones, and a wireless printer on the same network. However, I am excited to read more into wireless networks as I feel, as I may have mentioned before, that wireless networking is the most promising field in networking research at this moment.
For research we are looking into Internet measurements similar to the ones we previously discussed in class, but this time for wireless networks. It is interesting to see how different wireless and wired networks act. For example, in wireless networks we need to consider the contention between various routers or end systems, where as in wired we are more focused on throughput, etc.
Since wireless is still a fairly new area of research, I believe there are plenty of useful contributions in the area of wireless networking that will be beneficial to the field. Some ideas for our specific area of research would include tracking wireless/mobile networks on the battlefield or tracking criminals using wireless devices, but other approaches could you useful for different situations.

Learning About Multicast
I was really interested to discuss Multicast this week in our Networking class, as a big fan of Hulu (the free version) and Netflix, I think it is fascinating the way that content, such as streaming video, is transported to clients throughout the internet. Although Hulu and Netflix don't necessarily have to use multicast to get their information out there, their protocols are probably similar.
I think this area of networking is important because I believe that streaming and downloadable media will eventually replace physical media, beginning with television and movies. In discussing this idea with my adviser, he felt that large scale streaming would "break the internet" due to the high bandwidth requirements. Therefore, smart ideas such as multicast to create content distribution networks will become more important in the future to ensure that the internet doesn't "break."
As for other forms of media, such as video games on consoles, it may take longer to get rid of people's attachment to physical media. The advent of content distribution systems like Steam on PC and Mac have shifted the trend on computers toward downloadable media, which runs faster than reading from a disk, but requires a large amount of storage, which is probably why it is not prominent in consoles that are limited to 120 - 250GB compared to 500GB - several TB on PCs.
