Cybercrime Computing & Networking Foundation

Overview

Our digitised society has transformed cybercrime and cyber-enabled fraud into a major revenue stream for organised crime groups (OCG). Action Fraud reports that 80% of reported frauds are cyber-enabled; they could have taken place offline, but their scale, reach and impact have been expanded using online services and digital technology.

Ransomware and the cost of cybercrime is already up a percent of global GDP, over £500 billion a year. The global cybercrime epidemic shows every sign of continuing to rampage through every global economy. This National Cyber Security Center (NCSC) assured course will give you a good understanding of a number of important topics needed as a Cybercrime Specialist, including:

• How a computer works and what its fundamental components are
• How do computers communicate via networks and what protocols are used
• What is binary and why do we use hex and not decimal
• Fundamentals of encryption, cloud and virtualisation
• An introduction to digital forensics and why the integrity of data is paramount no matter what your role
• An understanding of the Computer Misuse Act and Data Protection and why they are important
• Cybercrime threats and cybercrime offences

The follow-on course in the cybercrime pathway is the Cybercrime Investigators course .
