In this post I will discuss the basics of Facebook security, securing your profile from different areas of the site. Using these wisely can keep you out of search results, limit what is shown in search results, and keep your information private, or, as private as you want it to be. It's worth understanding.
The first thing you do is roll over the "Settings" link and select the "Privacy Settings" link that appears in the drop down menu, from there you are in the security/privacy configuration area of your Facebook profile. There are four basic areas of configuration.
- Profile - Setting who can see what in your profile.
- Search - Setting your search visibility.
- News Feed and Wall - Setting what appears on your wall and your friends walls/home pages.
- Applications - Setting what applications can see of your profile, which apps you've blocked and so on.
Profile Privacy
Clicking through to the profile privacy section you have two basic tabs of settings, basic, and contact info. All of the options are set using the drop down menu described above. This is pretty simple to set for basic security, as all the options can easily be set to "friends only" and your profile will basically not have anything visible to people that are not friends, but may have clicked through to your profile from a friends profile.
Search
This can be a powerful area to control the privacy of your profile. If you are the type that wants to find, but not be found, simply set the search visibility (the first option on the page at the time of this writing) to "no one" or "friends only". These settings will allow you to keep yourself out of search results for people that are not friends already. Below that drop down menu option there is a series of checkboxes that will enable/disable what actually shows up in search results when you are found. You can hide your profile picture, friends list and other various things.
News Feed and Wall
This page of options allows you to set which activity is published to your wall. By default Facebook shows every time you comment to somebody else's wall, comment on photos, start playing a game and all sorts of stuff. This can be shut off in the first tab of this page.
The second tab is the ever controversial use of people profile info and images in ads all over Facebook. I know I got weirded out the first time I saw an ad that had pics of my friends saying they challenged me to some such quiz or whatever. Well, in the "Facebook Ads" tab you can turn this off so your profile can not be used in those ads. Or only for friend, friends of friends, etc.
Applications
For many Facebook users, these applications can be the bane of their existence. The home page being filled with friends results of all these "what [insert whatever] are you?" quizes and such stuff. Many of these quizes are so poorly created they have typos, erroneous information, meaningless questions and more.
There are actually a few ways to handle this, first is with the "Settings > Privacy Settings > Applications" window. From here you can say exactly what information applications can have access to, lists blocked applications, and allows you to disable viewing of Facebook Connect sites and Beacon sites. Facebook connect is a way to use your Facebook profile information in other web sites that subscribe to the Facebook Connect service. Beacon web sites can be learned about here.
Additionally there is the "Settings > Application Settings" which contains a list of any application you have used, and allows you to set permissions and visibility for each application.
Lastly, if you have those friends that send you every quiz, smiles, hugs, drinks, gifts and whatnot and you don't want those things all the time, on your list of requests, under each request is a link to block that application. Then future requests simply won't be delivered. Sadly, there isn't a global block that I have found, so there are days I spend too much time blocking stuff, but that's one of those necessary evils. Everyone uses Facebook for their own reasons, some to play games and whatnot, some just to chat with people.
