How to ensure your organization’s resources? Learn now what is Zero Trust Network Access (ZTNA).
What is Zero Trust Network Access (ZTNA)?
ZTNA is an approach to access control that treats all network access as hostile. It assumes that the network is not trusted and that there are no implicit or explicit trust relationships with other networks. This approach contrasts with the traditional network design approach of “least privilege.”
Since it grants users and systems access to only the resources that they need to perform their assigned duties. Rather than focusing on giving users and systems the minimal privileges required. ZTNA assumes that all entities on a given network are untrustworthy and can compromise any resource assigned to them.
Therefore, ZTNA assumes that if an attacker gains access to a user account, the attacker can use it to attack other resources. This is such as file servers or application servers. To prevent this, ZTNA focuses on minimizing the reach of an attacker once they have successfully compromised one resource.
This article will explore how organizations can implement ZTNA architectures. So, they can have the highest level of security while still maintaining productivity.
Zero Trust Concept
The main idea of Zero Trust Network Access (ZTNA) is that all networks are untrusted. That is when it comes to resources and data. Even if an employee has been working at a company for years, it is assumed that they will still be able to steal information if they were able to gain access (network access).
The “zero trust” concept means that every entity connecting to a network must be treated as a potential threat. This is regardless of their position in the company and their history of accessing the company’s systems. The goal of ZTNA is to ensure that every entity accessing a cloud network does so with as few privileges as possible to reduce their ability to cause damage if an attack is successful.
Moreover, this prevents unauthorized individuals from accessing additional resources. Also, it limits their ability to exfiltrate data from existing resources since they have fewer privileges. For organizations to take advantage of these benefits, the IT team must define what each entity (person or machine) needs to accomplish its task.
What Is Zero Trust Network Access (ZTNA)? Identity Management
Zero Trust Network Access (ZTNA) is an architecture for identity management. It allows organizations to grant internal employees only those privileges required for them to do their job. While blocking any unauthorized external entities from accessing internal systems.
In practice, this means protecting applications rather than endpoints by implementing “least privilege.” Organizations can also use ZTNA to ensure that users are accessing a legitimate version of an application.
