What is Zero Trust Security | What Is Zero Trust

In this article, You will learn what zero trust security is, how it works, the benefits of zero trust architecture, and how to implement zero trust security.

What Exactly Is Zero Trust Security?

Zero Trust Security is a security model that authenticates users and prevents internal and external figures from accessing an organization or network unless thorough verification is performed.

As the name implies, along with the outsiders, zero trust means that the person working within the network should undergo a complete validation process to access data or other sensitive information.

What is Zero Trust Network Access (ZTNA)?

Composed of many complex and secure technologies and strategies, the primary base of zero trust security is layered by ZTNA, an abbreviation for Zero Trust Network Access. Zero trust operates on the premise that no one, both inside and outside the network, can be trusted and denies access to the data.

In short, if you want to align or implement zero trust security in your organization, you will need ZTNA for it. 

How Does Zero Trust Security Work?

Zero trust security was designed by John Kindervag in 2010. It protected valuable digital information from the crutches of unknown users who may use the data illegally or sell it without permission.

1. Registers and examines the network traffic

The foremost purpose of no trust is to guard the data by refusing access to any unwanted user. When someone logs into the system, the no-trust security gives them the least privilege, i.eThe user has to enter his credentials and mention the reasoning behind his work. 

2. Restricts access to the network

Nothing malicious or suspicious can be done after logging in to the system. Zero trust validates and regulates the accounts and monitors what applications the user opens and uses for his work. 

3. Validates and protects network resources 

It verifies each user and authenticates their network using the Application Programming Interface whenever they use any data or an application. It ensures that every user meets the guidelines set within the organization’s perimeter as security measures. 

Benefits of Zero Trust Architecture

An organization can get various benefits by including zero trust security as a part of its cyber security.

Its fundamental principle of restricting access to data saves it from any misuse. Some other perks of zero trust architecture are:

1. Fewer chances of threat

When everyone is verified before being given access to any information, it automatically lessens the chances of threat. This model saves one from the hassles of recovering data from the attacks of hackers or cyberbullies.

2. Assists in enhancing security

Zero Trust Security gives a detailed result to the organization about who accessed what resources of the firm and the reason for which they did. It aids the company in taking significant measures to ensure the content is safe.

3. Upgrades the monitoring

Implementing zero trust security is equivalent to reducing the risks and unethical tricks often palpable in the cyber world. No one can use the data without being appropriately authenticated; even the insiders are attested first if they want to look into any data. 

4. Improves user-end experience

Remembering many different passcodes and passwords to access the applications can be challenging. Zero trust aids the users in accessing various files and data they need to perform their work by simplifying the passwords.

5. Works as an insurance

In case of a data breach or stolen information, Zero-trust security acts like an insurance policy by keeping a close eye on every action done in the network. It denies the entry of unauthorized users. 

Zero Trust Security Use Cases

It runs on the principle of “trust no one unless proven otherwise.” One may be unaware of zero trust security’s many features and advantages. It can be understood easily by looking at its many use cases. Some of the examples are:

1. Third-party

The primary use case is third-party involved in the business. Many companies enable corporate networks for their employees to give them entry into the network perimeter. However, it also allows third-party or suppliers to access the files. Zero Trust Security limits the rights of such people in the network and eliminates the need to connect third-party with the company’s devices, thus resulting in a safe collaboration.

2. Operational Technology

Operational Technology demands safe access for its clients without hindering the production work of the companies. It is required to maintain the flow while restricting network access.

3. Remote working

It is one of the most trendy use cases for now. Employees working from home need a way to access the company’s files and applications to carry out the work. Companies are expected to build a secure method to grant access to such employees without risk and complication.

4. IoT 

Internet of Things (IoT) is subject to many insecure transfers of data and applications, lack of visibility and management, weak passcodes in the name of security measures, and frequent attacks from hackers. Using it to share and receive information is akin to digging your grave.  

5. Privileged Access Management

Users of PAM or privileged access management can only enter the network with unique access rights they have. However, many times the access activities are not regulated and controlled.

How to implement Zero Trust Security?

If you are new to implementing zero trust security in your organization, it is a given that it will take some time. To include it in a company, one has to get started first. What are the key steps to execute it? 

1. Figure out the areas

Rather than covering the whole network, it is better to find the area where the essential information regarding the company is and outline it for security.

2. Understand the functioning of your network

Take note of your previous controls and security methods and observe how your network responds to them. Make a plan on what additional measures you need to implement.

3. Add security measures

Once you have decided on the areas where you need to build your zero trust architecture, formulate a list of measures you would take for its security to restrict access to those critical areas.

4. Zero Trust Policy

Set specific criteria to gain access to the key areas. People interested in accessing files must fulfill the criteria to enter the network. Otherwise, they will be denied access. 

5. Regulate the permissions

Once the setup is implemented, you can use this security model to track the actions of your employees. Zero trust security maintains records and documents how much activity occurs in the critical network areas. You can modify the criteria for access or permission standard per the situation demands.


Unfortunately, breaches and fraud have become customary in the cyber world, and one can never be sure when they fall victim to it. Implementing tight security aspects with the help of zero trust architecture will only benefit you and your business in the long term.

No unauthorized access will be able to enter the network perimeters.
