Research suggests that by 2021, cybercrime will cost the world $6 trillion annually. IT today is responsible for managing a larger attack surface than ever, thanks to end-users relying on personal devices for work, and accessing cloud apps and corporate resources from remote locations.

So, how can you deliver the access your employees need to do their best work while protecting your organization from cyberattacks?

Answer: Zero Trust Security Strategy

The zero Trust security model was created in 2010 by John Kindervag, who was a principal analyst at Forrester Research Inc at that point in time.

What is zero trust security model?

Zero Trust is a security concept centered on the belief that organizations should not automatically trust anything inside or outside its perimeters and instead must verify anything and everything trying to connect to its systems before granting access.

In other words, zero trust security model requires strict identity verification for every person and device trying to access resources on a private network, regardless of the network perimeter. 

To add on, there is no one technology when it comes to zero trust architecture. It is a holistic approach that incorporates several different principles and technologies. 

The end of castle-and-moat concept: The beginning of the zero trust security model

Traditional IT network security is based on the castle-and-moat concept. This approach considers people who are inside the network as trustworthy. And considers people who are outside the network as someone not to be trusted. As a result, access to enter the network is denied to them (people from outside the network) straight away. 

However, this approach misses an important point. That is if an attacker gains access to the network somehow – then they can easily enter the network. Not just that but can control everything that’s inside. Isn’t that scary?

As a result, this security practice is no longer suitable to meet the complex security needs of today’s modern enterprises. Because the information in the current times is often spread across different cloud vendors. 

As a corrective measure to the security questions raised by the cast-and-moat security concept – the zero security model was born.

As the name suggests – zero trust security means, no one is trusted by default. Be it from inside or outside the network. And verification is a must for whoever is trying to gain access to resources on the network. This added layer of security without a doubt has helped prevent data breaches. 

Read this 2020 Zero Trust Progress report to explore how enterprises are implementing zero trust security in their organization to tighten the reins on access security while giving users their choice of devices and apps. Thereby, minimizing risks and spiking productivity.

Also, a recent IBM-sponsored study found that the average cost of a single data breach is over $3 million. Considering this, it’s no surprise if organizations start adopting the zero trust security model in bulk.

How does zero trust security model work?

It works on 4 basis principles:

1. Zero trust on people inside and outside the organization

The zero trust security model trusts no one when it comes to security, be it – people inside or outside the network. Not just people, it doesn’t trust the machines as well without running a series of strict security checks. 

2. Least-privilege access

This refers to giving access to users only as much as they need depending on the requirement and after a layer of the security-check procedure. Thereby, minimizing each user’s exposure to the enterprise’s/network’s sensitive information.

3. Microsegmentation

Microsegmentation refers to breaking up security perimeters into small chunks/zones. So that there is separate access for separate parts of the network. 

For instance, a network with files stored in a single data center that utilizes microsegmentation may contain dozens of separate, secure zones. This means a person or program with access to one zone will not be able to access other zones without proper authorization.

4. Multi-factor authentication

The zero trust security model relies on multi-factor authentication greatly. This means just entering a password is not good enough to gain access. But requires more than one piece of evidence to authenticate a user.

For instance, in addition to entering a password, users who enable 2-factor authentication for these services must enter a code sent to another device, such as a mobile phone, thus providing two pieces of evidence to prove – they are who, they claim to be. Thereby, adding an additional layer of security.

In conclusion,

72% of companies today are implementing a zero trust security model to fight cyberattacks. With remote work trends rising every day, the best gift you can give your employee and your organization is – ‘Zero Trust Security Model’. This model is the ultimate solution to building security from the inside out and not the outside in. 

Give your employees the support and security they need while they work hard to meet your business requirements. Support your employees working remotely by providing more secure access to corporate resources through continuous assessment and intent-based policies.

Make it easy for your employees and your organization!
