The evolution of the internet is both a bliss and a curse. Daily, the world comes across several stories related to innovations and development as well as cyber hacks and online scams. All such incidents create trust issues among individuals. To contain such crimes and maintain people’s trust over the internet a security model, Zero Trust Architecture was introduced.

What is it and how does it operate? Let’s uncover the unbeatable features of the high-tech security model.   

What is Zero Trust Architecture (ZTA)?

Zero Trust Architecture is a security model that mitigates security challenges by rectifying the trust assumptions within the network. With ZTA, the identification and elimination of anticipations in the security rules become effortless.   

John Kindervag, a Forrester Research analyst, popularized the term in the world of the internet in 2009. Google, the tech giant, was the first company to apply the architecture termed as BeyondCorp.    

Based on the principle of “never trust, always verify”, ZTA acts as a blueprint for applying the features of zero trust, designed with the current realities of cyber threats in mind. Detecting and rectifying every threat over the internet is challenging for business firms, and zero-trust practices offer a way to permit and control access across the system.    

Why Do We Need ZTA?

Digital transformation expanded its roots across every field of business, but security is often ignored. As modern problems require modern solutions, the world of remote working, distributed IT infrastructure and cloud migration, require the application of ZTA.   

As the business world is gradually evolving, the need for a safe, secure, and scalable solution boomed. The ubiquity of cyberattacks, higher security stakes, culture of work from home, expanded workforce, and cloud data centers, increased the thrust for a model that not only trusts security but verifies the same.  

No matter where the world is moving, the need for cybersecurity and related practices will remain a steady need for business enterprises.  Zero Trust Architecture holds a great future, mainly in the field of customer data, IP, and employee security.   

Three Security Domains of ZTA 

When it comes to security, ZTA shines as a leader. The security model has entirely changed the game of security. The model follows and verifies every user, system, or device connected with the system, ensuring that each interaction is a safe interaction. The entire working of the model falls under three ZTA domains and are as follows:

Domain 1: The first domain is focused on granting access and ensuring the effective implementation of the three tenets. Application and verification of “Authentication and Authorization”, “Observable State”, and “Integrity” helps in granting permits to authorized persons to the system. 

Domain 2: Domain 2 of the ZTA is completely focused on controlling access and attaining the same using two principles. No proper application and verification of the “Minimal Access to Size” and “Minimal Access to Time” could result in a security breach. 

Domain 3: ZTA’s third domain is focused on monitoring and securing access and this is done through two tenets. A proper application of “Monitor All Access” and “Encrypt All Access” would result in reduced network vulnerability and lower chances of environmental attacks.  

Advantages And Disadvantages

ZTA came up with several benefits for organizations including improved security stance and declined attack surface.  The model also increases the system visibility and situational awareness, making it effortless to detect real-time threats and rectifications. Improved scalability and agility, on the other hand, made it effortless for business firms to cope with new technologies and infrastructure.   

On the flip side, shifting to the ZTA model requires a shift in culture, relevant change management, and skills. Also, every organization holds a legacy system that may pose the planning and execution of the security model. Rectification of these issues can help organizations become highly secure and protected from cyberattacks.         

Conclusion

Zero Trust Architecture is a security model focused on security verification despite security trust. The model secured its strong place in the business industry mainly by offering top-notch security. The entire model mainly operates in three domains which are granting access, controlling access, and monitoring and securing access. ZTA secures Web3 from rising cyber threats and scams.
