What Are the Key Components of Zero Trust Network Access?

In this section, we will explore more about the key components of Zero Trust Network Access. This post will take a look at some of the critical components of ZTNA.

Introduction 

Zero Trust Network Access is the access control policy for the networks. This is implemented in a manner that provides the right type of access to only the right people.

The term “Zero Trust” was coined by Forrester in a report in 2013. It is a concept where a network or system is treated as untrusted until proven trustworthy.

In this type of model, there is no assumption of trust, and all traffic is considered a potential threat. The main objective of the ZTNA is to provide access to resources only when it is required for all users.

Users, applications, and devices are considered untrusted entities. In addition, they need to be authenticated before they can gain access to the systems and networks.

The Zero Trust Network Access model is a combination of the concepts of perimeter security, user’s identity, and risk-based access. Thus, it helps in defining the access control for the users and devices. 

What Are the Key Components of Zero Trust Network Access?

The Zero Trust Network Access model is a combination of the concepts of perimeter security, user’s identity, and risk-based access. It helps in defining the access control for the users and devices. 

In addition, it allows an organization to implement policies based on the users’ needs.

The following are the key components of Zero Trust Network Access:

1. User Identity

In Zero Trust Network Access, identity is one of the core components. The identity of any user is verified before they can gain access to the systems or networks. 

Identity verification is also important to ensure that the user is authorized and has access to the resources.

2. Authentication 

This verification process is related to user identity. The identity is verified through various means and the authentication process is different for different users. 

In addition, it depends on the risk associated with the user’s identity. Authentication is a requirement for gaining access to the network and its resources.

3. User Risk Assessment 

The system needs to assess the risk associated with each user’s identity. The risk assessment process will be based on how risky the user is in terms of information security and business continuity. 

So, the more risky a user is, the less access they will get. If a user poses a high risk, then they will be unable to gain any access to the networks and resources.

4. Resource Access

When a user identity is verified, and the risk assessment process is passed, then they will be provided with the resources and access. 

The user will be provided with the necessary access to the resources based on their requirements. The ZTNA model does not provide unlimited access to the users. Instead, it provides only the required access to all users.

Conclusion – Zero Trust Network Access

The Zero Trust Network Access model is an important component of the overall access control policy. It helps in identifying the risks and vulnerabilities associated with any user or device. In addition, it helps in preventing unauthorized access to the networks and systems.
