A Seminole County Sheriff's deputy has been charged with using his Facebook account to lure a teen.
Jonathan Warner is never too far from his Facebook page.
"I check it at least three or four times a day," said Warner.
He says he keeps in contact with friends and co-workers using the popular social networking site through his laptop computer and smart phone.
But Jonathan worries about who has access to his page.
That's why Stephen Cobb with the computer security company ESET says it is time to go over your security settings on your Facebook page. Facebook comes with a set of default settings, but Cobb says people may be surprised what it allows others to be view.
"They usually find they are sharing more than they thought they were sharing," said Cobb.
The "security evangelist" says the place to start is clicking on the downward arrow in the upper right hand corner of your Facebook page, then clicking on "account settings" and "privacy settings."
Security settings allow you to decide where you will access your Facebook page.
It will actually block access from an unfamiliar computer unless you give it a certain password.
That password can be sent to you through email or text message.
Speaking of passwords, "You want to change your password to something fresh and also something that is very hard for other people to guess," Cobb advises, "and something you are not using on other accounts."
Cobb says you should not use the same password for Facebook that you use for your online banking.
Scam artists are always trying to hack into Facebook and other social networking sites in order to access financial websites and email accounts.
By going into the "privacy settings" on Facebook users may limit access to their accounts to "Friends" only.
They can also control which apps and websites are able to collect and share Facebook information.
Now that Facebook has taken on the "Timeline" homepage, it means users should take another look at what is accessible to visitors. It may be time to limit exposure to just "friends" rather than "friends of friends."
Jonathan Warner tries to control who views his page but admits, it's not always easy.
"I hear so many horror stories of people getting in trouble with their postings," said Warner, "Just because they're not keeping it private and it is really unfortunate."
Call it Facebook for the famous.
A man who Palm Beach Gardens Police arrested in 2011 for stalking young girls at a candy shop is now in federal custody accused of using Facebook to find victims.
Have you ever checked to see what the public sees when they view your Facebook page? Just because you thought something was private doesn't mean it's not public.
Relieved your kids aren't posting embarrassing messages and goofy self-portraits on Facebook? They're probably doing it on Instagram and Snapchat instead.
The result has been lower numbers on fan pages, including some of the site's most popular ones, but no actual loss of real followers.
Facebook isn't just for connecting with friends -- doctors are finding uses for the social network in diagnosis.
Facebook has had a rough first three months as a public company. The social network's stock has performed poorly since going public in May, and on Monday morning it dropped to an all-time low of $18.75.
Beginning Thursday, users can upgrade. The Apple app is the first to launch; Facebook wouldn't comment on when its Android and other mobile apps might get a revamp.
