Internet in a Suitcase: Stealth WWW

This post is an excerpt from U.S. Hopes "Internet in a Suitcase" Will Offset Internet Censorship.

The U.S. government has created what it is calling an "Internet in a suitcase" to cheat the switches on the filtering regimes of repressive countries. A kit of hardware, the suitcase creates a "shadow Internet" within a country that allows users to communicate with each other and the outside world despite electronic censorship.

The suitcase was funded by a $2 million grant from the U.S. Department of State, according to the New York Times.

"(T)he suitcase," the Times reported, "could be secreted across a border and quickly set up to allow wireless communication over a wide area with a link to the global Internet." It creates a mesh network of interconnected device, each acting as a sort of miniature cell tower.

Hackers are scary: Time for two-factor Authentication?

This post is an excerpt from Is it Time for Two-Factor Authentication?.

The recent security breach at Citibank, coupled with even RSA hiring what may be its first Chief Security Officer Edward Schwartz, point out that you can never be too paranoid about your personal and corporate data security. RSA was in the news earlier this year for an attach on its SecurID two-factor tokens, something that had been considered the ultimate in enterprise security.

It might be time to take another look at two-factor authentication, and see if it makes sense to implement this in your organization. Here are three basic steps to get started:

First, take a look at what Google and Facebook have done with adding two-factor authentication to their accounts. Both use somewhat similar systems, tying your account to your cell phone and sending you a text message that you have to enter as part of your login process. Google adopted two-factor authentication last fall and Facebook added two-factor to their accounts in May. And eBay/PayPal have had two-factor authentication for several years on its accounts, too. While these are all personal solutions, they help gain experience in using these two-factor solutions and give you some perspective before you want to implement these corporate-wide.

Google software structure obsolete?

This post is an excerpt from Ex-Google Engineer Says the Company's Software Infrastructure is Obsolete - ReadWriteCloud.

Yesterday former Google Wave engineer Dhanji R. Prasanna wrote on his blog about why he is leaving the company. It's an interesting look at Google's company culture, but there's also an interesting technical nugget in there. "Google's vaunted scalable software infrastructure is obsolete," Prasanna wrote. He emphasizes that the hardware infrastructure is still state of the art, "But the software stack on top of it is 10 years old, aging and designed for building search engines and crawlers."

Prasanna says software like BigTable and MapReduce are "ancient, creaking dinosaurs" compared to open source alternatives like Apache Hadoop.

Is this okay? Anonymous taking on countries?

This post is an excerpt from ReadWriteWeb.

Once Anonymous, the hacking collective, got the taste of blood on the world stage, credit card companies seemed to be less tantalizing. Some of these country operations have been more successful than others. Although the success may be more in focusing attention on the issues the citizens themselves are fighting for than any real damage against the repressive infrastructure.

So far we've seen Operation Tunisia, Operation Zimbabwe, Operation Egypt and Operation Iran. Now, Anonymous has turned its attention to the subcontinent in Operation India.
