Keep multiple backups for your critical and sensitive data

In case of accidental deletion, data loss is often noticed several days after it has actually occurred. This means that if your only backup is from last night, you have no way of retrieving all your data.
Restoring files which were deliberately deleted months or even years ago, when you thought you would never need them again, can often be of great benefit.

There are plenty of options available for people backup up their data. For example, if you back up your computer to an external hard drive, but leave that drive connected when you are not doing backup, some ransomware will try to encrypt those backup filed as well: always disconnect backup drives when the backup has finished.

  •  USB stick : Small, cheap and convenient, USB sticks are everywhere, and their portability means that they’re easy to store safely, but also pretty easy to lose. There are questions about the number of read/write cycles they can take, so should be considered alongside other backup methods.
  • External hard drive : External hard drives are just what they sound like – hard drives that live outside your computer, meaning they can be plugged in to other sources. If using them for backup, it’s best not to use them as an ‘extra every day hard drive’.
  • Network Attached Storage: Organizations/Companies tend to backup their files to network attached storage, but with more and more homes having multiple computers, the idea has a certain appeal, especially for those looking to save files from more than one source. With prices coming down, a dedicated wireless storage solution is a convenient option which requires less thought.
  • Cloud Storage: While network attached storage is essentially your own Cloud Server, there are plenty of third party cloud storage options around: free, paid, or free with paid extras. iCloud, Dropbox, Google Drive and OneDrive are big names, but others are available.
  • Printing: At a first glance, this might sound a facetious inclusion. But while considerably less technically advanced, printing offers you a hard copy of your most important documents that will survive power outages, and are easy to store and access even if your computer is out of action for a few days. Of course it’s hard to keep documents up to date this way, and it won’t work for video or audio files, but for that novel you’d be devastated to lose, it’s certainly worth considering.

Don’t use USB keys,CDs, or laptop drives for unencrypted sensitive data

Using simple storage media for transfering data from computer may seem innocuous, but it has the potential to cause many problems for a user.These devices (such as a CD's ,DVD's) plug into the USB port of your PC and may contain malware that you copy unknowingly or that gets launched automatically by the Autorun or Autoplay feature of your PC. Never copy unencrypted sensitive data to harddisk ,cd's or any media.
Always protect your sensitive data using encryption tools like bitlocker,verecrypt.Encrypting your information is a bit like keeping it in a locked safe. To transport files from one computer to another computer, learn how to encrypt data while using a USB key, or burning CDs, or copying data onto laptop drives. Be sure that sensitive data is encrypted and then stored in USBs, CDs or laptop drives. Sensitive data should be encrypted when it is transmitted.

Avoid providing others information without their consent while you are in chatting

Children while chatting with their friends or other person may sometimes share their private or personal information like their name, school address, house address, and phone numbers through text messages. The information which they have shared can be viewed by other people who are online and sometimes it might be sent to wrong address. The persons who receive the information may misuse it.
There are potential risks in communicating to people that you don not know, and unfortunately some children have been hurt having gone to meet the friends they have made online. Adults with a sexual interest in children have used chatrooms and other interactive areas online to make contact with and befriend children, and then ‘groomed’ them that is persuaded and manipulated them to meet up where they have been abused.

Never give out personal details
The most important of these is to never give out your personal details.  This means not telling people your real name, even just your first name.  If there is someone unsavory in the chatroom, they can start to use your name to gain your trust.
You also should not tell anyone how old or even your gender.  That might sound a bit odd, but if there is an adult in the chatroom who is trying to target young girls or boys, you are giving them the information they need.
Other information that you absolutely must not give out are any details about where you live, you should not be telling people your actual address or even which town you are from as that gives them the chance to say they live near you and try to gain your trust.
You also should not tell them which school you go to.  It would not take a genius to track down a school. They only need a bit more information about you gleaned from your conversations in the chatroom for them to be able to identify you at school.
No matter what reasons or excuses people give, do not ever tell them your phone number.  They might make out that they really like you and they want to chat to you in person.  Do not be fooled, keep your phone number a secret.
Keep your email address a secret.  You might think that it cannot do any harm to let someone have your email.  But they might start sending you pictures that make you feel scared or uncomfortable. They could even send you a computer virus in the email.
Children love to use the chat rooms, they should be aware that people in chat rooms are strangers and may not be honest guys. The privacy policy may not protect information which you disclose via a chat. Never say anything in a chat about your personal information such as your name, home address, and school address, etc.
