Layered Approach To Security: How To Actually Stop Hackers (in 2020)

Are you wanting to know how to implement a layered approach to security that will actually protect your company from hackers?

One that causes them to be so frustrated that they give up and move on.

Then you will love today’s post.

Layered security is the only way to actually stop cyber attacks in 2020.

Let’s dive in:

Why is layered security so important?

This is just one example of layering security controls.

We will look at quite a few more.

What is a layered approach to security?

Cybersecurity attacks have evolved tremendously.

Today’s attacks are usually complicated and require the attackers to use multiple weaknesses along their path to full compromise.

Many times, attacks even involve a mixture of targeting humans (social engineering) and targeting system weaknesses.

The amount of devices on most networks today makes this even more complex - smart devices, printers, IoT, industrial devices, computers, servers, etc.

This simply means more ways that an attacker can get into your organization.

From our own experience doing penetration testing, it is very easy to get an initial foothold into most organizations.

If they implement a layered security strategy though, it will be much harder to pivot that initial foothold to gain access to sensitive information.

The Candy Bar Effect

A lot of security practitioners refer to the candy bar effect in cybersecurity.

Having a candy bar cybersecurity posture means that an organization has strong perimeter security - a crunchy outside. But they have not implemented a layered security strategy that makes it difficult for hackers to pivot through their systems once they are in - a soft inside.

This happens when security is focused solely on keeping hackers out instead of protecting sensitive data.

This security strategy is why we see massive data breaches so frequently.

When an attacker is able to gain access to a network, they are able to pivot to areas that should be highly secured and exfiltrate sensitive data.

Let’s look at ways to layer security.

Network security layers

There are many ways that you can layer security.

One widely accepted layered security strategy involved seven layers of security.

These seven security layers are:

1. Mission Critical Assets

2. Data Security

3. Application Security

4. Endpoint Security

5. Network Security

6. Perimeter Security Layer

7. The Human Security Layer
