Select Edit Your Settings, and then locate Game and application activity, which is the third item listed on the resulting page. Next, select Custom from the drop-down menu and choose Only Me in the dialog box that pops up.

Now no one but you will be able to see your gaming activity through your Facebook profile.

Disable Facebook Apps Entirely

Sending out updates is just one example of what Facebook apps can do. Not all apps flood your newsfeed, but Facebook apps all have a common denominator: They can gain access to personal information you enter into your profile.

Author and former head of The Security Consortium Mark Kadrich is concerned about Facebook's quality control over third-party developers. "App developers are providing code for the Facebook environment," Kadrich says. "But how much security testing is really being carried out by Facebook before letting it loose on users?"

Facebook's policy is that application developers are not allowed to use your personal data off-site and are only supposed to access sufficient personal information to allow them to run, or to "enrich" your user experience. But once an app has access to the personal information that it needs, it's up to the app developer to keep that information safe.

If you're not happy with third parties having access to your information, the best course of action is to block all applications on Facebook.

Under Applications you use, select Turn off all platform applications:

Controlling What Your Facebook Friends Tell the World About You

Just as you might not want people to know where you are, you also may not want your friends passing on information about you either. Your friends have access to your profile, and they can repost items you posted to your wall--such as photographs--to their own profiles, or share the information with others, all without you knowing or having any control.

Your Facebook friends may also be using Facebook apps themselves--these apps may have access to their friend lists for information, and that includes you. To better control who can access your private information, you have to control what information your friends can give out about you.
