Have you heard of the Zero Trust security model? The concept is relatively new, but highly efficient in the industrial segment.
To understand the importance of this methodology, it is essential to keep in mind that alongside digital advancements, cyberattacks have also become increasingly refined.
Today, establishing effective security control over user access to networks and software is an undisputed concern. Especially with the advent of remote work and industrial automation, this topic is gaining traction and has already become a priority for many companies.
In this context, the Zero Trust model emerges as a viable strategy for the industrial sector. Want to learn more? Read on to discover everything about the subject.
What is Zero Trust?
The approach was popularized in 2010 by IT analyst John Kindervag. He used the term to explain a concept based on “never trust, always verify”.
This means that, unlike traditional security models, Zero Trust is built on the core premise that no user or device is trusted by default. Based on this principle, authorization to specific areas or sensitive data must be tied to continuous authentication and verification.
Given the rise of cloud tools, it has become common for people to access networks remotely from the data center. However, this facilitates unauthorized connections and makes devices more vulnerable to cyberattacks and data theft.
Therefore, the process also evaluates user behavior. This means that even if an employee knows the password and has the credentials, if they connect from an unfamiliar network, Zero Trust identifies this action as a potential threat.
Finally, one of the key characteristics of this framework is access restricted to specific applications only. In the event of a breach, for example, the damage is minimized since the hacker will not gain control of the entire system.
The model posits that VPNs and “trust but verify” methods are no longer sufficient. For all these reasons, organizations are increasingly investing in this approach.
How does Zero Trust work?
As mentioned, Zero Trust operates based on constant verification and authentication. Consequently, network flows, devices, and users must obtain authorization for every access request.
The model’s architecture is complex and robust, incorporating multiple technologies, preventive techniques, and principles to address common security challenges. Operating under the assumption that there is no traditional network perimeter and that merely providing a password is not enough, these components are designed for advanced defense.
Accordingly, we outline four basic principles of this approach:
- There are continuous internal and external threats on the network;
- Network locality is not sufficient to determine trustworthiness;
- Every device, user, and network flow must be authorized and authenticated;
- Policies must be dynamic and derived from as many data sources as possible.
What are the benefits of Zero Trust in industry?
When it comes to Zero Trust technology in industry, the core tenets remain the same. However, the methodology is also applied to machinery, in light of the trend toward digitalization in manufacturing environments.
Considering Industry 4.0 and the emerging Industry 5.0, the use of cloud software, the Internet of Things (IoT), and machine learning tailored to the production chain is becoming commonplace.
Since network and solution access is constant, it is necessary to deploy more sophisticated security systems, such as Zero Trust. Discover the main benefits of this practice!
Protection against attacks
Cyberattacks can cause millions in losses. Industrial sectors handle formulas, proprietary techniques, and other confidential data. A breach or ransomware attack on these records and the database can compromise customer trust and impact market competitiveness.
This is where this approach serves as vital protection against attacks and unauthorized network access within the manufacturing environment.
Secure application access
Alongside attack protection, the model promotes secure access to corporate applications. This means the user’s physical perimeter does not matter. Even when operating tools remotely via technological solutions, security is never compromised or left vulnerable.
Resource optimization
Zero Trust is capable of detecting anomalous behaviors and non-conformities. This means that within the organizational environment, this tool can be used to identify machinery that is not operating as expected, considering IoT and operational digitalization.
If devices that have never communicated with each other suddenly start doing so—or stop communicating properly—the results can be disastrous. Production stoppages occur, resources are wasted, and the entire supply chain is compromised.
If the industrial plant utilizes this tool, such situations can be easily detected. The technology has immense potential to save extra resources, while boosting productivity and protecting all stakeholders.
Implementing a Zero Trust policy in the sector can deliver critical competitive advantages and numerous benefits, as you have just read. Therefore, investing in technologies that reinforce this practice is well worthwhile.
