Everything You Need to Know

Zero Trust Policy has become an integral topic of discussion ever since the Cybersecurity Executive Order 14028.

Organizations are wondering what a zero-trust policy is and how to incorporate it into their cybersecurity strategy. A zero-trust policy is no longer an option, it is now a mandatory element for every company.

Tekkis Cybersecurity understands the importance of the Zero Trust Policy for small businesses. Additionally, we are aware that most small to medium businesses do not have in-house cybersecurity set up to handle the policy implementation.

Therefore, in this article, we will provide all the details of everything you need to know about the Zero Trust Policy. You will not only understand the basics of this policy but will also get to know how to incorporate it into your business.

What is Zero Trust Policy?

While the width and the scale of the zero-trust policy are far-reaching, its essence is quite simple. In essence, the zero-trust policy dictates that trust cannot be assumed when it comes to any element of IT infrastructure.

Zero trust policy requires that every party in an organization, whether it is the users or applications, should be authorized as well as validated. With a zero-trust policy, there is no default trust regardless of who the user is or what the application is.

The zero trust policy also goes hand in hand with the principle of least privilege access. According to this principle, organizations should only provide users with the minimum level of access they require for completing their assigned tasks.

How Does Zero Trust Policy Work?

It might surprise you to know that the general IT security protocol used in most small to medium businesses is decades old. It was designed in the 90s, based on the concept of a centralized data center.

The Old Security Model

In the old network framework, anything using a ‘valid’ IP address or using a ‘valid’ port was allowed entry into the database. The definition of ‘valid’ was preset into the network. This had a huge drawback because there was no real-time security present.

Once a user was inside the network, they had access to utilize the network however they require. The older model opens the entire network at the user’s disposal.

Trust was given to preset IP addresses, ports, and protocols by default. This leads to huge open windows for attackers to exploit.

The New Security Model- Zero Trust Architecture

Zero trust architecture (ZTA) is entirely different from this older model prevalent at that time. While the older model worked aptly for the time it was designed, it is quite outdated now because of our new network architecture.

In zero trust architecture, every user and data packet inside a network is treated as hostile by default. Once the validity of the user is established, they gain access to a limited part of the network.

The limitations are defined by the network administrator beforehand based on the job requirements of the user.

Principles of Zero Trust Architecture

The zero trust policy is based on several principles that are very different from the outdated model that passes for cybersecurity in most businesses. Here are the principles of the zero trust architecture.

Real-time Connection Analysis and Termination

Generally, when you consider the old cybersecurity model, the security layer is created by a firewall solution. This solution detects the data packets that have reached the organization’s devices. If the packet is malicious, the connection is then terminated.

However, since this approach waits for the data packets that are delivered, the alerts are too late; the damage has already been done.

The zero-trust policy, by default, terminates all connections to an organization. The network traffic is then processed and analysed in real-time by an in-line proxy and only safe connections are allowed entry to the organization’s devices.

Direct User-to-app Connections

Traditionally, if the employees of an organization wanted to use any job-related application, they had to connect to the organization’s network which then connected them to the app.

Since the users were open to the entire network, this increased the possibility of attack significantly. With Zero trust policy, we reduce this wide span that is open for attacks.

This is made by a protocol specially designed for zero trust architecture, called Zero Trust Network Access (ZTNA). In ZTNA, users are connected directly to the apps and services they require.

The direct user-to-app connection in ZTNA eliminates the connection to the rest of the network, which is unnecessary anyway. This creates a very secure bubble and eliminates the possibility of network attacks.

Context Definitions

In a zero-trust policy, data is filtered and permitted through a context-based approach. The data is segmented based on the user’s authentication, location, device, access requested, etc. If the context is verified and permissible, data is allowed through.

The context definitions are flexible and can be updated by the administrator whenever required. These definitions allow for easy implementation of the least-privilege approach.

How to Implement Zero Trust Policy

When you hire a cybersecurity agency to create a zero-trust architecture for your company, a good service will follow a systematic approach. Implementing this policy is basically a three-step process:

Advantages of Zero Trust Policy

A major question that business executives ask is ‘What are the advantages of a zero-trust policy?’ Since adopting the zero-trust policy can take some effort, it is vital to know beforehand if the advantages are worth it.

Here are some of the benefits that the zero-trust policy has to offer:

Better Protection

Starting with the most basic advantage, the zero-trust policy creates a better security framework for the company. A well-executed zero-trust policy makes it nearly impossible for attackers to breach the organization’s defenses in any way.

Better Access Control

With a Zero trust policy, every user gets as much access as the job requires of them. In the earlier structure, every person in the organization had the same, limited access and control over the network.

The new structure has a very modular approach for access controls. The administrators can define the access that users get based on their job description and their level on the workforce ladder.

Reduce Impact

Due to better filtering, least access, and risk mitigation, there is reduced impact even in the case of a successful data breach. For instance, even if a user is able to access an authorized employee’s credentials, the location filters will still prohibit the breach. Even if the breach was still accomplished, the network they can access will be very limited.

Compliance Standards

Nowadays, several compliance requirements such as the NIST SP 800-207 enforce the implementation of a zero-trust policy for companies that interact with cyberinfrastructure. Implementing the ZTA makes sure that the companies aren’t sanctioned during government audits.

Applicable on Current Setup

To implement the ZTA, you do not require hiring any new team members or investing on new infrastructure. The zero-trust policy can work seamlessly with your existing IT setup, regardless of how it is designed.

The only thing you need to make sure is that you choose an experienced cybersecurity provider for setting up your ZTA. If set up correctly, a zero-trust policy can even save you money in the long run.

Work From Home Optimized

In the last two years, we have seen more and more companies opting for the work from home (WFH) approach. While this approach has proven to be productive and more feasible, it also opened up big cybersecurity risks.

Implementing a zero-trust policy can secure the connections even for WFH employees. It makes the zero-trust policy more and more unavoidable in the day and age where work from home culture is increasing steadily.
