2. Cyber Security can be defined as the steps taken to prevent
misuse or unauthorized access of computers/user accounts.
OR
It can be defined protecting yourself in this “Web” world.

3. The two broad classification of cyber security are :
•Web Security : It refers to to security associated with
Internet.
•Home Security : Home security is associated with keeping
your personal system secure from various threats.

4. Components of Web Security :
•E –Mail Security : E-Mail is used by almost every person who uses
internet. But rarely people worry about their security .Most of the
people make an email account and rarely change it's password ever
, making the account very vulnerable!
•Facebook Security : These days everyone is on facebook and many
accounts get hacked .We think that security of facebook is very low
due to which the accounts get hacked .But facebook has been
pentested so many times that its security is very high and its the lack
of awareness of the users that their accounts get hacked . Many people
don’t change passwords regularly or often open up some link which
are nothing but scripts leading to hack their account.

5. •Online Banking Security : Most of the banks offer a very good security
but still on the side of the users there is carelessness which leads to leak
of confidential information.

6. Components of Home Security :
•Antivirus : Ensuring that we have a good anti-virus which protects
your computer from any external harm by viruses , trojans etc. is a
must. One should update the antivirus regularly too.
•Firewall : A firewall is a tool whose main objective is to control the
incoming and outgoing data packets in a network. It determines
whether the packets are valid or invalid on the basis of some pre
determined rules.
•Good Password : Users should keep a good password which cannot be
easily guessed by others. A good password contains a combination of
words , numbers, shift keys etc..

7. Facebook being the most accessed site all over the world makes it
the prime target of attackers . So here are some tips to increase the
security of your facebook account :
One Should always keep the following options enabled in
Facebook :
•Secure browsing - Enable 'https' tag to the url instead of
http, HTTPS is more safer and secure.
•Login notifications - It tells you about from where your account
has been accessed,if you find a fishy location,change password
immediately
•Recognized devices - By choosing this option you can specify the
devices by which you use facebook,if your account is accessed by
an unrecognized device,fb prevents login from that device.

8. •I would recommend girls to make "groups'' in your friend list . Put those
people in 'acquaintances' who you don't know or trust less as these are the
people who leak your photos .
•Putting such people in “acquaintances” ensures security of the data you
post on fb , as people of this group are unable to see most of the
pics, statuses you update.
•DON'T add strangers..a bit less comments on photos are surely better than any
harassment :P

9. Here are some interesting Tweaks which you can always try out
during free time :
•Play “Snake Game” on youtube - All you have to do is press –
"left mouse button+left arrow+up arrow“, and the snake game
begins!
•Post display pic as emoticon in fb chat : You can add facebook
profiles,like pages etc. in facebook chat.All you have to do is
type the unique username like this : [[username]] . For example
Facebook username is facebook.com/john . So, If I have to post
my image in the chat I will type [[john]] and press enter.

anyone due to a loophole in security.
