Cyber security and Computer Misuse Unit: Social & Economic Impact of Information and Communications Technology Cyber security and Computer Misuse

Introduction We live in a digital era where so much of what we do is done within a finger tip. Whether it’s ordering from a restaurant, shopping online or even making hotel reservations. We are constantly using the internet and as such are also regenerating data stored online through cloud storage. Today we will be focusing on cloud storage and elaborating more on cyber security.

Objectives At the end of the lesson, students should be able to: define cyber security differentiate between vulnerability, threats and attacks Name five threats associated with cyber security explain the five threats associated describe countermeasures to mitigate against these threats

Cyber security

What is Cyber Security? Cyber security is the protection of internet-connected systems, including hardware, software and data, from cyber attacks.

Elements of Cyber security the possibility of being attacked or harmed Vulnerability Threats Attacks intention to inflict pain, injury, danger or damage an aggressive and violent act

Cyber threats and attacks
