How to be safe on Facebook in times of spams.

In this time of increasing frauds, spams and hacks going on, how could facebook (world's second m,ost used website) be spared. You can see some new spam or hack methodology coming out everyday and compromising accounts of lame people. For those who are noobs to such things, there are some of the settings which must be implemented in order to be safe from such stuff. here are some of those settings.

1. Who can see what?

Your first stop should be your privacy settings, which you can get to under "Account" at the top right of any page.
Here, make sure you're using a set of custom settings. Click "Customize settings" under the grid on that page to see who can see which parts of your Facebook profile.
Unless you use your Facebook account as a public page, every option should at least be set to "Friends Only." From there, you can make each setting more specific, keeping your photos hidden for certain people, for example.

2. Place your friends in lists

To make the previous tip more powerful, place your Facebook friends in lists. If you begin to define lists such as Coworkers, Best Friends, Employees, Students, etc., you can set each of your settings to be visible or not visible to a whole list of people.
To do this go to "Edit Friends" under the Account menu. Type in a friend's name and add it to a list.
Then you can make sure that only your best friends, for example, can see the photos you post. Or you can make sure that your students or employees don't see your status updates.
You can also add a friend to a list as you accept their friend request.

3. How secure is your password?

This is the front line to your Facebook security and should be taken seriously. Good passwords include capital letters, punctuation, numbers and words that can't be found in the dictionary.
Resist using anything that someone who knows you well enough could guess (kids, pets, phone numbers, etc.).
If you think for any reason that your account's security has been breached, change your password immediately. Doing so will end every active session of Facebook for your account, locking out anyone else but you.

4. Who can find you?

Facebook also allows you to set what people see if they're not your friend. Under privacy settings, click "View Settings" under the "Connecting on Facebook" setting at the top of the page.
Here, you can set what people see when they search for you on Facebook.
Pay special note to the bottom option, which allows you to set who can see what you have "liked" on Facebook. Many don't realize that by default this option is set to show everyone on the Web what you like.
Don't want that future employer to know that you "like" naps or skipping class? This is a good thing to check.

5. What does my profile look like to Grandpa?

Even the most conscientious Facebook user can miss a check box or two, putting his or her entire weekend escapade on Facebook for Grandpa to see.
But the good news is that you can preview what your profile looks like to any of your friends, many of whom can see different things depending on how advanced you have set your privacy settings.
In your privacy settings, click "Customize Settings" then "Preview My Profile."
Here, you'll be able to type in any friend's name and see exactly what they see. Very handy.

6. Browse Facebook securely

One of Facebook's most vulnerable features is that much of your browsing is done without a secure connection to the Web site. Hackers have exploited this hole by accessing your personal information if you use Facebook on a public or unsecured WiFi network.
In your account settings, choose Account Security. There's a check box there to enable secure browsing whenever possible. Check that.
You'll soon see that Facebook will be using https:// instead of http://. That's how you know you're more secure.

7. Who is logging in as you?

One of Facebook's greatest security features is the ability to individually approve each computer or mobile device that logs into your account.
You can name each computer you use Facebook with (work, home, laptop, iPhone, etc.).
To turn this on, go to your account settings, click on "Account Security" and choose that you want an e-mail or text message when someone tries to log in from a computer that isn't one you've approved.
Here, you can also see all the open sessions of Facebook tied to your account. Someone logging in from five states away? Click "end activity" and they'll be stopped in their tracks.

8. Which apps know you?

As we have used Facebook over the years, each of us has amassed lists of applications that have access to our Facebook information.
To see which apps currently have access to your Facebook information, go to your privacy settings and click edit under "Apps and Websites" at the bottom left of the page.
On the next page, click edit settings next to "Apps you use."
Here, you'll see a list of all the apps that have your information on file. Many of them are used for convenience, such as integration with the popular Instagram photo-sharing app or commenting services on news Web sites. But there are certainly some you could lose.
Click the X next to any app from which you want your information yanked.

9. Even your friends' apps know you, too

This one is even scarier. On the same app privacy page, check out the subhead that says "Info accessible through your friends."
You may not know it, but anything your friends can see on Facebook can also be seen by any app that your friends add on Facebook — including apps that you have no idea were ever given access.
To disallow this, click on edit settings and uncheck all the boxes that allow you to choose what can be shared with apps that your friends add. Click save.

10. Who can post on your wall?

Many of these spammy links are clickjacking schemes, which spread by posting links on a bunch of your friends' walls.
The only foolproof way to prevent these links from gumming up your own wall is to set it so no one can post directly on your wall. Friends can still comment on your status messages, links and photos, but won't have the ability to leave you a public note.
To change this setting, head to the customize settings area under privacy. Then uncheck the "Enable" box where it allows friends to post on your wall.
