Stepping Up Your Cybersecurity with Defense in Depth (DiD)

Cybersecurity is an essential aspect of any business or organization. As technology evolves, so do the threats that can harm an organization’s operations, data and reputation. One of the most effective ways to defend against these threats is through the Defense in Depth (DiD) approach.

DiD is a cybersecurity approach in which multiple defensive methods are layered to protect a business. Since no individual security measure is guaranteed to endure every attack, combining several layers of security is more effective. This layering approach was first conceived by the National Security Agency (NSA) and is inspired by a military tactic with the same name. In the military, layers of defense help buy time. However, in IT, this approach is intended to prevent an incident altogether.

Essential elements of DiD

Implementing all the elements of an effective DiD strategy can help minimize the chances of threats seeping through the cracks. These elements include:

1. Firewalls

2. Intrusion prevention and detection systems

3. Endpoint detection and response (EDR)

4. Network segmentation

5. The principle of least privilege (PoLP)

6. Strong passwords

7. Patch management

How IT service providers help defend against threats

An IT service provider will help you divide DiD into three security control areas:

1. Administrative controls

2. Technical controls

3. Physical controls
