In the Wikileaks aftermath, the military has reportedly banned disks and USB drives and threw in the threat of a court martial for good measure. Should you do the same for your corporate network? Wired reported that the U.S. military is telling troops to ditch removable media. The problem is that these "sneaker networks"-actually combat boot networks-are an efficient way to get data from one point to another. The big question here is whether enterprises should also put some limits on removable drives. Let's face it, there are a lot of removable media that can tap into corporate networks. USB drives, iPods and phones are just some of the avenues where data can escape.

Tor is free software and an open network that helps you defend against a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security known as traffic analysis. Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Tor works with many of your existing applications, including web browsers, instant messaging clients, remote login, and other applications based on the TCP protocol. Hundreds of thousands of people around the world use Tor for a wide variety of reasons: journalists and bloggers, human rights workers, law enforcement officers, soldiers, corporations, citizens of repressive regimes, and just ordinary citizens. (Note: sometimes ITGS students need to be able to access sites that are sometimes blocked)

Though teachers and students are now pushing learning beyond the borders of the classroom through social networking, that move also comes with hurdles, including the fact that many schools still block access to such sites within their walls. School officials must also confront the uncertainties and questions surrounding privacy issues, proper management, and cyber security when they open their doors to social-networking sites.

Too complex for students but useful background for the teacher. Smart sensor networks - technologies and applications for green growth 12-Jan-2010 Sensor networks play an important role in tackling environmental challenges. Sensor applications in smart power grids, smart buildings and smart industrial processes make significant contributions to more efficient resource use and reduce greenhouse gas emissions and other pollutants. This report gives an overview of sensor technologies and applications, and quantifies their environmental impacts.

"AN ANGRY red dot flashes at the top of your computer screen. As your mouse creeps over it, a message appears: ''Twitter use has exceeded the department average of 58.6 minutes per day - please self-regulate.''

Outstanding show, explains a lot about worms vs viruses as well as botnets. It's an interview with the author so it also illustrates how to ask good questions. (useful for the project) The gigantic networked system created by the Conficker worm is what's known as a "botnet." The Conficker botnet is powerful enough to take over computer networks that control banking, telephones, security systems, air traffic control and even the Internet itself, says Bowden. His new book, Worm: The First Digital World War, details how Conficker was discovered, how it works, and the ongoing programming battle to bring down the Conficker worm, which he says could have widespread consequences if used nefariously.

"A key feature of several of the intrusions was the use of wardriving, a technique in which hackers mount a high-strength Wi-Fi receiver inside a vehicle and search for networks that can be penetrated. Once a Wi-Fi network is located through wardriving, hackers can remotely watch for information that may reveal the network's security setup and vulnerabilities."

Interesting term 'wardriving'

"The IEEE has published two important new standards for WiFi mesh networking and peer-to-peer communication between WiFi devices. It says the latter could produce a 10 fold increase in the data rate between connected devices."
