PART A [40marks]
Information security is a broad term encompassing the protection of information from accidental or intentional misuse by persons inside or outside an organization. Information security is the primary tool an organization can use to combat the threats associated with downtime. Cyber security refers to the protection of information systems (hardware, software and associated infrastructure), the data on them, and the services they provide, from unauthorized access, harm or misuse. This includes harm caused intentionally by the operator of the system, or accidentally, as a result of failing to follow security procedures
Write a report on your investigation of personal & business information cybersecurity threats and abuses and controls/measures/practices to protect personal/business data. Classify each threat as either perceived or real.
