LIFE ON THE INTERNET

16. UNDERSTAND LIFE ON THE
INTERNET
The Internet has turned our
existence upside down. It has
revolutionized communications, to
the extent that it is now our
preferred medium of everyday
communication. In almost
everything we do, we use the
Internet. Ordering a pizza, buying a
television, sharing a moment with a
friend, sending a picture over
instant messaging.
The Internet has so much control
over almost every aspect of
human life, not only our private
lives but, also various public
services.
There are unforeseen
consequences to sharing our
private and public information and
the results could damage our
presence on the internet.

SECURITY

THE
CONCEPT
OF
PASSWORD
SECURITY
WHAT IS A
PASSWORD?
A secret string of letters,
symbols, and numbers
that you can use to restrict
people, who can access
something digital.
WHY DO I NEED A
PASSWORD AT
ALL?
Passwords provide the
first line of defense
against unauthorized
access.
HOW OFTEN
SHOULD I CHANGE
MY PASSWORD?
Ideally, every 6
months.
WHAT SORT OF A
PASSWORD
SHOULD I HAVE?
Preferably, strong.
WHY SHOULD I
HAVE A STRONG
PASSWORD?
It makes it very hard
for bad men and
criminals to access our
data and hurt us.
WHAT ARE THE
DO’s AND DON'Ts
OF A PASSWORD?
Let’s learn about it
further!

28. DO’s
AND
DON’Ts
OF
PASSWORD
MAKING
Never disclose your
usernames and
passwords to
strangers.
Do not use the
‘remember me’
options or save
passwords on a
public computer or
network.
Initially, consult
with your parents
before you create
a password. Once
you get the hang
of it, you can do it
on your own.
Run regular virus
scans on your
devices; say
every week or so.
Never store your
usernames and
passwords on a paper
or in an easily
accessible place.

29. LET’S DO AN ACTIVITY!
Start with a phrase. Think of a quote or
group of words that will be easy to
remember.
Example: I am in grade three.
Write down just the first letter of each word
in the phrase.
Example: I / A / I / G / T
Capitalize some of the letters. Example: I / a / i / g / T
Add one or two memorable numbers. Example: I / a / 3 / i / g / 2 / 6 / T
Memorize it. Repeat your new password in
your head so it sticks.
Therefore, you new password - Ia3ig26T
