1) Protect your updates  You can protect your updates in Twitter so that only persons you allow will see your tweets. This feature is indicated by a little padlock. If any time anyone clicks for following you, you’ll be sent an e-mail asking whether to allow it. You can check out their profile and have a look at their tweets and can obtain a general idea about them. After this you can decide whether to give them the permission or not. Also follow the rule “Don’t make friends with people you don’t know” to protect your account.

2) Watch your words

Don’t write on Twitter and Facebook details about vital information like phone numbers, bank details, car registration, home address etc. Also try not to disclose your holiday plans if you have displayed the home address in your profile as it is a temptation to thieves.

3) Don’t Geo-tag everything.

You should remove the meat data when you are uploading your images to Twitpic, Facebook, or Flickr. You should take a look at your look in your camera or phone to see whether auto-tag feature is enabled with your picture. Most of the photos you snap at home and upload on the web will pinpoint exactly your living place. This may be a security problem so make sure you’ are not Geo-tagging your home pictures.

4) Keep your personal away from your business

You should use two separate user accounts for your business and personal matters, otherwise both of them will get mixed up. By using the same account multiple purposes, intimate details of your personal life may be revealed through the net. It is not a good idea that you combine the tweeting about your whereabouts and tagging all your home snaps in a same account.

5) Don’t click on every single link that comes through

You should not click on every single line of hyperlinked URL which comes in Twitter and Facebook. You should make sure that the sender of the link is a trusted person. If you know the sender, 99% of the time there will be no issues at all, and on that 1% of the time, your friend, from whom the malicious link came, will probably warn you.
