How to avoid identity theft

Publish any personal information in any form and on the internet is an action that can not be justified. However, we can not blame the social networking site just because they provide a place for its users to communicate and interact more comfortably. Awareness of the importance of the meaning of information security and data privacy already owned by each user's internet service itself.
To avoid this we can do some of the following ways:

• Do not write the information themselves in detail or in a public place accessible to the public.
• Even if do not have to write it all, make some data (not necessary all) that is not appropriate, may be age, date of birth job. But do not fill out with fake identity for the serious registration form.
  
• Avoid writing the name of parents, especially mother - given the many credit card companies still use the mother name as secret question.
• Avoid using a very precise answer to every secret question, for example, "who is your childhood hero" answer with the name of the school or your pets.
• Perform the removal or manipulation of data birthdays in social networking site
• Delete the history & surfing impression especially in public area, such internet cafe, office.
• Dont show/tell your ID or alias name to unknown or unfamiliar person.
  

My Facebook account is cracked...

Yesterday night after using the internet, I immediately went to bed but before I try to update the status in facebook mobile, but apparently I can not, even though the correct password is entered, tried many times still can not, I finally went to sleep aja, tried only in the PC.
The next day, I try on PC, same result ... the result : (, And then I open the e-mail account that is used to facebook, there is notification of the security warning that the contents facebook:

We have detected Suspicious activity on your Facebook account and have your password reset as a security precaution. It is possible that malicious software was downloaded to your computer or that your password was stolen by a phishing website designed to look like Facebook .........

They ordered to me to change my password and update antivirus and finally I am trying to do, this time using the password with a combination of letters numbers, which he said was powerful and the password is longer than before and this time, thanks god, facebook can be accessed again.
I just could not get it, a friend who chat with last night also experienced the same thing, I suggest doing the same thing with. can this mass attack? ... hehehe. A friend on FB also recommend changing your password often, I thought this great idea, and I also remember about cookies and privacy settings enter the firefox, I finally find the "accept third party cookies' option that by default there is still mark, then I removed signs mark because I suspect this is the cause, my facebook is cracked, I also set "keep until" to "close firefox", but cookies also more important for adsense program, banking site, webmail, etc. My suggestion, activate them if you just need it and dont activate cookies in fake sites, porn sites, etc.
