Information Security is another way of saying “data security.” So if you are an information security specialist, your concern is for the confidentiality, integrity, and availability of your data. Most modern business data resides electronically on servers, desktops, laptops, or somewhere on the internet—but a decade ago, before all confidential information migrated online, it was sitting in a filing cabinet. And some confidential information still is! InfoSec is concerned with making sure data in any form is kept secure and is a bit more broad than cybersecurity. So, someone could likely be an information security expert without being a cybersecurity expert.

Cyber Security is defined as the ability to protect or defend the use of cyberspace from cyber-attacks.
