4. WHAT IS CYBER SECURITY?
• Cyber security refers to the
technologies, processes, and
practices designed to protect
networks, devices, programs,
and data from damage,
unauthorized access or
attacks delivered via internet
by cyber criminals.

• However the same technology may expose you when it’s
vulnerable and could lead to loss of essential data.
• Cybersecurity become one of the most important topics in
the business industry to be talked about.
• Cyber security is necessary since it helps in securing data
from threats such as data theft or misuse, also safeguard
your system from viruses.

6. Cyber Attacks
• A cyber attack can maliciously disable

computer as a launch point for other
attacks.

7. Types Of Cyber Attacks:
• Malware attacks
• Phishing
• Password attacks
• Hacking
• Viruses and worms
• DoS and DDos
• Man in the middle attack
