The Afterglow effect and Peer 2 Peer networks Masters
Jerome Radcliffe, - August 25, 2010
Overall there is room to grow in the area of P2P connection research. This limited study only looked at a small area of P2P interactions. There are an ever‐ growing number of BitTorrent clients and all of them handle the protocol differently. These differences could greatly impact every area of P2P communications, all of which are areas that could be grounds for research. Further research of how P2P clients interact could provide additional ways to increase efficiency and provide enhanced security.
An Open Source Layer 2 Switch
Jim Wilson - May 4, 2010
Small networks tend to grow and often times the growth is unplanned. The result is a network of daisy-chained switches, not the most reliable solution for a multi switch environment. What is needed is a solution which integrates all switches into a single collision domain or IP space. Most administrators would look at a Cisco solution at this point, but maybe we can use a Linux box instead. The Linux bridging software allows us to create a single LAN segment and combined with other Open Source software provide management and monitoring capabilities.
Hey Dude! I Can Do a Great Humphrey Bogart!

Auditing and Securing Multifunction Devices Masters
Charles Scott - October 15, 2007
It used to be that a printer was connected directly to a computer via a serial or parallel interface, while fax machines and copiers did not connect to a computer at all. You knew where these devices were in your buildings and securing their physical output was your primary concern. In today's all-in-one world, you can now obtain single devices that are not only printers, but also copiers, scanners, and fax machines. These networked multifunction devices (MFDs) are increasingly common in enterprise environments and are manufactured by vendors such as Canon, HP, Kyocera, Xerox, and many others.
