Are you using your real name on your social network profiles? According to the European Union's Network and Information Security Agency (ENISA), that's a big mistake. A new report, published to coincide with Europe's Safer Internet Day, details the dangers of using social networks and lays out 17 "golden rules" for keeping safe on social networks. The report's authors are especially worried about the proliferation of mobile social networks and, among other things, recommend that users turn off all location-based services whenever they are not absolutely needed.

Swiss researcher Nicolas Seriot claims it's possible for "rogue" applications to make their way into the iTunes App Store where they could then be used to steal personal data from victims' iPhones. According to Seriot's research, the problem has to with Apple's lax approval process for applications as well as a flaw in an iPhone security feature that provides access to more data than is necessary. If a malicious application was installed on someone's iPhone, it could use this loophole to quietly harvest personal data including phone numbers, address book information, the phone's unique identifier and more. Then, using the phone's Internet connection, it could send that data back to remote servers, all unbeknownst to the iPhone's owner.

Are you goofing off on Facebook at work? As it turns out, this sort of "time theft" may be no longer be your company's top concern when it comes to social networking in the workplace. According to a new study from security firm Sophos, the real problem with social networks - and most of all Facebook - is the security risk they pose to organizations.

Yesterday afternoon, just before President Obama's first State of the Union address, the websites of the House of Representatives and those of multiple congressional members were defaced with anti-Obama messages. Among the defaced sites were those of Democratic Representative Charlie Gonzalez of Texas, and Republican representatives Spencer Bachus of Alabama, and Joe Wilson of South Carolina. These sites are currently down for maintenance.

"This status is being tracked. The owners of Facebook have confirmed they will send $1 to the rescue fund for Haiti every time this is cut and paste as a status." Sound familiar? This recent status message hoax has been making its way around the popular social network, duping members into posting the status as their own in the hopes that, by doing so, they've somehow contributed to the Haitian earthquake disaster relief fund without having to actually open their own pocketbook to do so. While that would be nice if it was true, this hoax is just one of many found on Facebook today.

It looks like Microsoft has moved to the "sticks and stones" method for handling public relations gaffes. As we reported yesterday, France joined Germany in suggesting that its citizens switch from Internet Explorer to, well, anything else. Now, Microsoft's UK security chief, Cliff Evans, has responded by saying that switching to other browsers will only open you up to more security vulnerabilities than staying with Internet Explorer.

That's saying a lot for the browser implicated in the Great Google Caper of 2010 and we have multiple security experts who said a lot on why it just isn't true.

After years of trying to convince technologically inept relatives to stop using Internet Explorer, computer geeks worldwide may finally have something new to back up their words: the advice of the German and French governments.

The French government joined Germany today in recommending that its citizens switch to another browser in light of last week's admission by Microsoft that Internet Explorer 6, 7 and 8 all contained the same security vulnerability, in which "Internet Explorer can be caused to allow remote code execution."

It's one thing to have resolutions for the new year. I, for example, plan to lose weight, learn Python and design the perfect handbag. But since nothing satisfies like the quick achievement of a short-term goal, here are eight things every good nerd needs to to before the ball drops later this week.

These tasks comprise a quick to-do list that will leave you feeling competent and prepared for the decade that approaches. Also, you can play the condescension chip and start chiding friends who haven't checked off these items yet.

In a chat today lasting over an hour, we got to talk to a person claiming to be the infamous hacker behind RockYou's latest data security woes.

While he claimed to have no animosity toward users, he had one clear message for websites: Take better care of your customers' data. RockYou isn't the only hacked site storing plain text login information, either.

Mobile technology, virtualization, the social web, cloud computing - a think tank study has all our good friends on a hit list.

The study, which shows primary security and privacy concerns of U.S. government IT leaders, is making the rounds among military and government bloggers. Policy makers are being told that the applications we know and love are dangerous and pose gaping security loopholes for cyberterrorism. Is a Big Brother overprotective meltdown? Or are our advances really causing greater risks for all users?
