Across the world, 72% of all businesses have either adopted Zero Trust or are in the process of implementing it. As more organizations adopt a Zero Trust model, it’s essential to know the fundamentals of how the security strategy works. Zero Trust Security is a new way of thinking about cyber security that assumes any user, device, or application might be malicious.

It’s based on the principle that the network should not trust anything outside of it. It has shown a $1.75 Million cost reduction in data breaches. In this article, we’ll take a look at what Zero Trust Security is and learn more about how it compares with traditional security models. We’ll also explore some of the benefits and risks associated with Zero Trust networks.

What is Zero Trust Security?

It is becoming the basis for a growing number of cloud integrations due to its effectiveness in addressing security needs. Zero Trust Security is a new security model that is being adopted by a number of companies. It’s an alternative to the “trust everyone” model that has been used in the past.

In Zero Trust Security, you do not trust any user, device, or application until they have proven themselves to be safe. This means all authentication is done via a central authentication server, and all users must go through multi-factor authentication before accessing any data. This system addresses threats such as ransomware attacks, insider threats, and supply chain attacks from any privileged remote workers.

How Does It Work?

This architecture revolves around identification, security, and segmentation. The Zero Trust Architecture works on 3 main principles.

1. Terminate all connections so no user can access the network without proving their identity. The architecture scans all encrypted and unencrypted traffic to prevent any malicious attacks.
2. Implement a network access control and device control with multi-factor authentication that is stronger than just using a password. Zero Trust allows access based on various factors such as identity, context, device, type, location, and application. The user privileges are also routinely reassessed to implement any verifications.
3. Limit privileged access by allowing direct access to only the resources and applications needed by the employees and never the highly crucial resources such as the network. This also causes the users and applications to be out of sight on the internet so they can’t be discovered and attacked.

How Does It Compare To Traditional Models

Traditional security models assume that the network perimeter is well-defined and that all traffic flows through it. This type of security model is called a “perimeter-based” or “trust-based” security model.

Zero Trust Security (ZTS) assumes that the network perimeter is not well-defined and all traffic can flow anywhere across the network. ZTS relies on identity to determine whether to trust a device, user, or service. It also makes regulatory compliance easier, requiring users to have the least privilege by default.

The main idea behind Zero Trust Security (ZTS) is to reduce the number of sections where an attacker can enter your organization’s environment by removing any trust from devices and services at the network perimeter.

Why Should Businesses Invest In Zero Trust Model

Zero Trust networks are a model of network security that assumes that any connected device is untrusted and should be treated as such. This means that the network allows users to authenticate themselves before they are granted access. The benefits of Zero Trust networks include the following.

Improved security.

Security threats can lie anywhere- inside your network or outside. Today’s business infrastructures are distributed across various physical sites, public and private cloud systems, platforms, numerous virtual machines, and operating systems. With users logging in to these systems remotely and accessing them using multiple devices, it is quite necessary to place a security system to protect your employees, your data, and your applications, and Zero Trust does exactly that. It authenticates and authorizes every and any person or device that accesses the business resources.

Frequent patching

Contrary to the myth, patching is crucial to system security. It takes one weak spot to destroy the entire system. A vulnerability and patch management system are needed to keep enterprise devices in their most safe and efficient working condition. The Zero Trust Architecture includes patching as a part of it.

Improved Usability

Zero Trust Architectures improves user experience by mitigating the need for users to remember passwords and login data as access is automated. In addition, it also provides an ease to IT admins by implementing a software-driven model that improves streamlined management and visibility. Simplifying security administration, security scanning, and addressing, makes the admin’s job much easier.

Cost Saving

The Zero Trust Model reduces the system’s attack surface and alleviates the severity of cybercrime attacks. This reduces precious time and financial resources used in treating the attacks and cleaning up after a strike.

Traditional security systems are difficult to implement as they are not malleable to changes rooted in physical equipment. This makes them expensive, time-consuming, and hard to implement. Comparatively, Zero Trust Architecture is more adaptable and better suited to any changes that can be made in the future.

Use Cases of Zero Trust Security

1. Control over Cloud access and the container environments.
2. Control IoT visibility and security.
3. Reducing the risks of data breaches.
4. Compliance with regulations and privacy standards.
5. Safeguard businesses and organizations from any kind of risks.
6. Secure all remote access in a multi-cloud environment.
7. Make the thor-party access secure.

Conclusion

In the last two years, the integration of Zero Trust in businesses has shown twice the chances of preventing any essential outages due to cyber attacks. In today’s world, implementing the best and most advanced security measures has become an absolute necessity in order to be safeguarded from the growing number of sophisticated attacks.

Implementing the ‘never trust, always verify’ model will give you an edge over your competitors by improving customer experience, adding value to security, giving you more insights into the ever-changing attack surface, and mitigating any system damage.
