Chapter 1. Information and Data Security Fundamentals

Computers have been instrumental to human progress for more than half a century. As these devices have become more sophisticated they have come under increasing attack from those looking to disrupt organizations using these systems. From the first boot sector virus to advanced, highly-complex, nation-state threats, the ability for an adversary to negatively impact an organization has never been greater.
