Establishing Security Defenses

Overview

This lesson is about establishing security defenses on computer systems. It’s the Protect function from the NIST Cybersecurity Framework. These defenses:

Reduce the risk of data breaches and disclosure
Prevent unauthorized access
Minimize vulnerabilities by keeping your devices and applications updated
Use email and the web safely

The more you can automate these activities and establish security procedures as part of your normal routine, the less chance you’ll need to respond to or recover from a security incident.
