Pros & Cons Of The Zero Trust Network Access Model

The Zero Trust model is a security architecture that does exactly what its name implies: it trusts no one, not even those inside the network. Every entity (internal or external to the network) is deemed to be a possible danger and must not be deemed safe until it has been examined and validated. 

As a result, every device and user in a company must be monitored and regulated. This stringent security procedure has advantages and disadvantages, which we will discuss. However, before we delve into the pros and cons of the Zero Trust Network model, let’s first understand what it is all about. 

What Is ZTNA?   

Zero Trust Network Access (ZTNA) is an information technology security framework  that governs  or enables secure remote access to an organization’s applications, data, and services based on explicitly defined access control criteria. A ZTNA-based product or solution varies from virtual private networks (VPNs) in that it only allows access to certain services or apps, whereas VPNs provide access to the whole network. 

As more users access resources from home or anywhere else, ZTNA solutions can assist in filling gaps in existing remote access technologies and techniques.

Access to particular apps or resources is provided only once the user has been authenticated. . Once verified, the ZTNA-based product/solution allows the user access to the specified application via a secure, encrypted tunnel, which provides an additional degree of security by concealing apps and services from IP addresses that would otherwise be exposed.

In this way, ZTNA functions similarly to software defined perimeters (SDPs), depending on the same ‘dark cloud’ concept to prohibit users from having sight into any other apps and services they are not authorised to access. This also protects against lateral assaults, because even if an attacker got access, they would be unable to check for additional services.

The Pros of ZTNA   

Should this framework be incorporated into your company’s security procedures? Establishing a Zero Trust network is a significant undertaking, but it is occasionally worthwhile to go the additional mile. Let’s take a look at some of the benefits and drawbacks of a Zero Trust-based model to help you determine if it’s suitable for you.

Here are a few of Zero Trust model’s advantages:

1. There is less susceptibility: Once implemented, the Zero trust model improves the company’s security, particularly against in-network lateral attacks that may materialize under a different security architecture.
2. Strong user authentication and authorization policies: Zero Trust necessitates tight supervision of users within the network in order for their accounts to be more safe, –thus making the whole network more secure. Utilizing multi-factor authentication, or even going beyond passwords and utilizing biometrics, is an excellent method to keep accounts secure. Then, using user classification, individuals may only be allowed access to data as well as accounts that are required for their specific work activities.
3. Data categorization that is insightful: In a Zero Trust paradigm, there would be no one large pool of data which all users can access. Data segmentation based on kind, sensitivity, and usage results in a more secure arrangement. Critical or sensitive data is therefore secured, and possible attack surfaces are decreased.
4. Increased data security: Zero Trust also ensures that data is secure in both storage and transport. This includes automatic backups as well as encrypted or hashed message delivery.
5. Excellent security orchestration: This is the responsibility of ensuring that all of your security measures operate together effectively and successfully. In an optimal Zero Trust model, no gaps are left unfilled, and the integrated parts compliment one another rather than creating inconsistencies.

The Cons of ZTNA  

With all of these extra security benefits, the Zero Trust paradigm complicates security procedures. A few of the extra problems that come with such a thorough plan are as follows:

1. It takes time and effort to set up: It might be challenging to reorganize policies inside an established network since it must continue to function during the change. It is frequently easier to create a new network from the ground up and then switch over. If older machines are irreconcilable with the Zero Trust architecture, it will be essential to start from scratch.
2. Increased control over a wider range of users: Employee users must be more tightly controlled, with access provided only when absolutely necessary. Furthermore, users are not limited to workers. Consumers, clients, including third-party suppliers could also access or utilize the company’s resources. This means that there are numerous entry points, and a Zero Trust framework necessitates distinct regulations for every type of users..

1. There are more gadgets to handle: Today’s workplace environment comprises not only many sorts of people, but also various types of gadgets for each of them. Various devices may have unique features and communication methods that must be managed and secured accordingly.
2. Management of applications has become more difficult: Similarly, applications vary. Apps are frequently cloud-based and may be used across numerous platforms. They may be disclosed to third parties. App customers should be scheduled, evaluated, and adapted especially to user needs in accordance with a Zero Trust attitude.
3. Increased data security: Data is being kept in several locations, which implies there are more places to safeguard. Data configuration must be done appropriately and in accordance with the highest security requirements.

Conclusion

As you can see, the disadvantages of utilizing the Zero Trust approach stem mostly from the additional labor necessary to implement it. It is a solid security framework–it simply requires some effort to put up. 

The network is more safe when trustworthiness is not expected. If the organization is breached by a cyberattack, the virus will be unable to spread laterally throughout the network since that movement is restricted. In terms of security, this thorough, defined method is an excellent concept.
