The Importance of Cyber Security
Cyber security is important because smart
phones, computers and the internet are now
such a fundamental part of modern life, that it's
difficult to imagine how we'd function without
them.
From online banking and shopping, to email
and social media, it's more important than ever
to take steps that can prevent cyber criminals
getting hold of our accounts, data, and devices.

desired web page.

Stay Secure
Many websites will display a lock symbol in the
address bar. This is most commonly seen on the
payment page of an online store. This means the
website is using an HTTPS connection, which
makes it safe to enter your information.
Look for HTTPS

Personal Privacy
Personal privacy is the protection of personal data
from those who should not have access to it and the
ability of individuals to determine who can access
their personal information.
Public Wi-Fi
One of the biggest threats with free Wi-Fi is the
ability for hackers to position themselves between
you and the connection point. So, instead of talking
directly with the hotspot, you end up sending your
information to the hacker.
