The Zero Trust approach to cybersecurity  

At a time when organizations are opening various doors to cyberattacks such as working in hybrid mode and the use of cloud storage, it is increasingly complex for them to protect themselves against the risks of cyberattacks. This is when Zero Trust becomes an interesting solution to preserve your security. 
Let’s see together through this article what Zero Trust is, how it works and its benefits. 

What is Zero Trust  

Zero Trust is a term related to cybersecurity that is based on the fact that you should never trust and always verify. In other words, it is an information security model that limits default access to applications, websites and data to only what is necessary. A specific policy has been put in place to allow users to be able to work while preserving their security. The Zero Trust approach includes 2 dimensions: 

  • Proactivity: Be proactive in monitoring, managing and defending to be prepared for any eventuality.
  • Vigilance: Accept that the risk is omnipresent. Be on guard and assume that any requests, links, may be malicious; but also that any system or device can be corrupted

How Zero Trust Works  

In order to adopt the Zero Trust model in your organization, 3 main areas must be taken into consideration in order to adjust your security rules. 

Networks: Traditional networks internal to the company. 

The first step in implementing the Zero Trust model to secure your networks is to identify critical assets. Then, it will be necessary to set up a segmentation within your organization, you can go on macro or micro-segmentation according to your business model. Finally, the last step will be to apply access control rules according to the needs of the company. 

Information and systems: Application servers, containers, applications… 

Depending on your organization’s mission, external parties may use your information and systems (eg, you provide a web application to your customers). Thus, it will be a question of ensuring that your customers put in place: configuration security, cloud platforms, databases, etc. 

Users and devices: 

Zero Trust can be implemented with users via multi-factor authentication. The goal is to secure and monitor each device (computer, laptop, mobile). Compliance and governance rules will be applied to limit access to users who have an interest.  

The advantages of the Zero Trust model 

There are 3 major benefits to the implementation of this security model.  

Visibility: This model allows us to have an overview of the assets of the computer park which is inside or outside the company. Thus, it is possible to set up better monitoring of communications in real time. 

Analysis: The visibility enabled by a Zero Trust approach provides access to more detailed logging in the event of investigations related to a cybersecurity incident. Dynamic analysis also allows cybersecurity responders to get a better idea of the overall picture of an attack. Thanks to the Zero Trust model, we can see who is trying to access what kind of data. 

Automation: Many companies do not have a dedicated team to respond to incidents. By going with the Zero Trust model, you can benefit from anomaly detection and dynamic incident response. Artificial intelligence will detect, for example, that a user who is used to connecting from Canada would connect from China. His connection will then be blocked automatically. 

In short 

External upheavals often push us to review our organization in order to become more efficient and safe by preparing for any eventuality. This evolution has contributed to the creation of the concept of “Zero Trust”, where no device or connection should be considered secure. 

As we have seen through this article, the principle of Zero Trust has many advantages that cover the IT spectrum of an organization. 

However, being well supported for a project of this scale is a prerequisite in order to have the right resources for the implementation. Do not hesitate to discuss your cybersecurity issues with our team of experts.
