Zero Trust 101: Understanding Latest Security Model

By now, you’ve almost certainly heard about Zero Trust. Countless experts have addressed how critical it is to follow this security strategy in order to handle today’s cybersecurity issues. Knowing the fundamentals is important if you want to design a more robust security strategy that can support remote work, distributed teams, and more cloud-based tech environments.

Zero Trust 101: Understanding Latest Security Model

What is Zero Trust?

To protect its most precious resources, such as user data and intellectual property, the IT sector has traditionally depended on perimeter security techniques. Digital transformation and the shift to hybrid cloud infrastructure, on the other hand, are transforming the way businesses operate. It’s no longer enough to rely on a network perimeter. This is where Zero Trust came in.

Zero Trust refers to the security model that no longer presumes the actors, systems, or services functioning within the security perimeter can be trusted. Instead, it validates everything attempting to connect to its systems before providing access.

The security requirements of this data-driven hybrid cloud architecture are addressed by Zero Trust. It gives businesses adaptive and continuous security for their users, data, and assets, as well as the capacity to manage threats in real-time. This technique of never trusting and always verifying tries to secure every user, device, and connection.

How does it work?

As its name implies, Zero Trust is based on the idea of “never trust, always verify.” A Zero Trust approach is made up of numerous technologies and best practices that fall under this umbrella. Some of its most important principles are:

Least-privilege access

Zero Trust requires giving least-privilege access depending on who is requesting access, the context of the request, and the risk of the access environment. This lowers the risk of internal data exfiltration by limiting malware’s capacity to move from one system to another. This way, organizations can decrease risk, complexity, and costs when they implement Zero Trust.


Micro-segmentation is a technique for conceptually dividing a network into segments and controlling traffic both inside and between them. It enables granular policy controls to regulate workloads in a data center or multi-cloud environment, as well as limit the spread of lateral risks.

Thanks to this ability to create security rules at a granular, host level, organizations can implement a Zero Trust frame for their security systems inside their security architecture, regardless of whether applications are in the data center or the cloud.

Data usage control

Once users have access to data, data usage controls limit what they can do with it. This is increasingly done dynamically, such as withdrawing authorization to copy data that has already been transferred to a USB drive, email, or cloud apps.

Continuous monitoring looks at how users interact with data. This allows risk-adaptive security measures to automatically customize enforcement depending on users’ actions, ensuring that people are who they say they are.

Implementing a Zero Trust culture in your organization

It’s a lot easier than it looks to implement a Zero Trust architecture. Zero Trust does not necessitate a comprehensive technological revamp because it is an addition to your existing architecture. Instead, it can be implemented in stages, allowing you to use the tools and technology you already have. Here are some steps to implement Zero Trust in your organization.

1.   Determine your security priorities

You must first understand the existing status of your security in order to appropriately protect it. This entails examining your current assets and determining which areas you need to prioritize.

2.   Use new technological solutions

It’s possible that your security system has flaws that need to be addressed. You can address these flaws with the required tools and evaluate your processes to ensure that your work methods are in line with the Zero Trust approach’s security criteria.

3.   Rethink your security procedures

While trying to implement a Zero Trust culture into your organization, you’ll need to rethink your security procedures, adapting them to the Zero Trust principles. This might include changing a few basic work habits or completely overhauling your routine. In either case, you’ll need to train your personnel to follow the new strategy.

4.   Implement continuous network monitoring

Another part of a Zero Trust network is proper device behavior monitoring. Teams should implement technologies that continually monitor a device’s activity on the network once access has been given. Network monitoring can be aided by modern solutions such as network detection and response or AI for IT operations platforms.

The future is here

Even though it is a new concept, Zero Trust has been implemented by various organizations throughout the world. In a global study conducted in 2021, 42% of respondents stated that they had intentions to implement a Zero Trust strategy. Every minute you don’t take action, you’re exposing yourself to attacks. This is why you need to take action now if you’d like to protect your organization with trustworthy security culture.
