3.14. PROTECTING YOUR DATA

        Data protection is  safeguarding your data  from data
        damage or data access by unauthorised people. It is always
        a good practice to maintain and protect your computer by
        following some precautions and managing a few computer
        settings. Some of the important points to take care are:
           • Use proper passwords combinations for your
          computer login:  At the time to allocate passwords take
          care to use the combinations of small letters, upper case,
          numbers, and special characters like $, %, &, etc. These
          combinations are difficult to hack and will be able to save your computer from unauthorised access.

           • Install Anti-virus and Firewall:  Anti-viruses and  Firewall  will not  allow the  unwanted data  to enter  your
          computer. If by mistake you download any malicious code then antivirus or antimalware software will warn
          you and then will remove it from your computer. This way you will be able to project your data from getting
          damaged or stolen.

           • Encrypt Data: Data encryption is converting the readable data into unreadable encoded form to save it from
          unauthorised access. Sometimes sensitive data like personal credit card transactions you do in online purchasing
          or data from defence services need to be transmitted through the internet or any other network should be
          encoded to protect the information.

           • Secure sites: Websites that you access should be secured websites to avoid data hacking specially when you
          do online transactions using your bank details or credit cards. If the site address starts with https:// and a lock
          symbol, then it is safe to access.

        3.14.1. Who are Online Predators?
        Online predators are internet users whose main purpose is to trap innocent people for inappropriate relationships.
        They may be of older age and pretend to be of yours by creating fake social networking accounts with fake pictures
        to lure you to do illegal activities which can be online or face to face.

        3.14.2. What are Internet Scams?

        Internet scams are the use of Internet services to take undue advantage of others. Some internet users may take
        advantage of innocent people browsing the internet. They pretend to be different by using fake name, age, profile
        and do financial frauds by taking out money from their bank accounts or stealing their credit cards information
        and using it for online transactions or involving in some kind of unwanted relationships.
