Overview

This lab is an introduction to computer security in Windows. Cybersecurity is defined as the processes, technologies, and practices to protect networks, computing devices, and data. Cybersecurity is about the CIA triad – Confidentiality, Integrity, and Availability. Confidentiality is defined as protecting sensitive information from people who are not giving permission for that information. Integrity is about making sure information is trustworthy and accurate.
