Using Facebook and Twitter safely


By Elinor Mills of cnet.com

You and just about everyone else, it seems, are spending more and more time on Facebook and Twitter, updating statuses and checking friends' tweets. That's all well and good, of course, but the amount of personal information that all of you share in real time, and the level of trust implicit with the social networking sites, do pose particular security and privacy problems.

A recent study from Sophos found that Facebook users reveal a lot of personal information to new friends, including ones they really don't even know or have never met. Using fake profiles, Sophos sent out friend requests to 100 random Facebook users, and more than 40 percent blindly accepted, giving the company access to birth dates, e-mail addresses, phone number and addresses--private information strangers shouldn't have.

The openness of Twitter--anyone can follow anyone else, and posts are indexed in search engines--makes it a nirvana for spammers. Kaspersky says there are nearly 500,000 new unique URLs that appear in Twitter posts daily, and of those, anywhere between 100 and 1,000 are malware attacks.

Here's a look at some of the specific threats users of the sites face and what they can do about it.
