Use a layered cybersecurity approach to protect crown jewels

When discussing cybersecurity, Sajay Rai, CPA, likes to compare an organization’s network and systems to a castle.

The moat surrounding the castle is analogous to the network’s outer defenses. But additional defenses exist, too—a gate, sentries, and locks. And the crown jewels, locked away in a safe place, are protected more than anything else in the castle.

Rai said the additional layers of defense also should exist in an organization’s systems, with the most sensitive information protected by the most layers. According to Rai, organizations that for many years invested security resources primarily into their outer network perimeter now have learned that it’s important to beef up other layers of defense, too.
