Zero Trust Validation: From Practical Approaches to Theory

Scientific Journal of Research & Reviews, 2020

How can high-level directives concerning risk, cybersecurity and compliance be operationalized in the central nervous system of any organization above a certain complexity? How can the effectiveness of technological solutions for security be proven and measured, and how can this technology be aligned with the governance and financial goals at the board level? These are the essential questions for any CEO, CIO or CISO that is concerned with the wellbeing of the firm. The concept of Zero Trust (ZT) approaches information and cybersecurity from the perspective of the asset to be protected, and from the value that asset represents. Zero Trust has been around for quite some time. Most professionals associate Zero Trust with a particular architectural approach to cybersecurity, involving concepts such as segments, resources that are accessed in a secure manner and the maxim "always verify never trust". This paper describes the current state of the art in Zero Trust usage. We investigate the limitations of current approaches and how these are addressed in the form of Critical Success Factors in the Zero Trust Framework developed by ON2IT 'Zero Trust Innovators' (1). Furthermore, this paper describes the design and engineering of a Zero Trust artifact that addresses the problems at hand (2), according to Design Science Research (DSR). The last part of this paper outlines the setup of an empirical validation trough practitioner oriented research, in order to gain a broader acceptance and implementation of Zero Trust strategies (3). The final result is a proposed framework and associated technology which, via Zero Trust principles, addresses multiple layers of the organization to grasp and align cybersecurity risks and understand the readiness and fitness of the organization and its measures to counter cybersecurity risks.

Zero Trust: The Magic Bullet or Devil’s Advocate?

European Conference on Cyber Warfare and Security

The concept of Zero trust was first introduced in mid 1990’s, and has gradually attracted increasing attention. This approach to building organizations’ information system infrastructures has been developed as response to increasing interaction and interconnection of information systems. Along with organizational boundaries have become less clear with the new business models where a business process exceeds the organizational boundaries, also the boundaries of information systems are no longer clear. In this interconnected world the purely perimeter-based security model defining zones of trusted entities inside the perimeter and the untrusted external world outside the perimeter no longer serves the needs of new business models. And the combination of complex technology and sophisticated attack methods it is no longer possible to be sure that all system components and actors inside the perimeter can be trusted. The Zero trust approach brings the sophisticated controls from the perim...

By examining case studies and industry examples, it demonstrates how Zero-Trust can effectively enhance cybersecurity in today's dynamic threat landscape. This paper serves as a valuable resource for understanding and adopting Zero-Trust Security Models to bolster organizational security and protect against modern cyber threats.

Zero Trust Architecture: Trend and Impact on Information Security

International Journal of Emerging Technology and Advanced Engineering, 2022

Traditional-based security models are a threat to information security; they have been regarded as weak and ineffective to meet the dynamics of information system trust. An emerging framework, Zero Trust Architecture (ZTA) seeks to close the trust gap in information security through enforcing policies based on identity and continuous authentication and verification. This framework is built on several trust nodes and logical components that attempt to close the trust gap that exists in an information system. The adoption of this framework is still in its teething stage which is a result of several misleading deductions and assumptions. We attempt to explore the intricacies in the framework and close the existing knowledge gap. we surveyed the literature on ZTA and provided a foundational discussion on its implementation and effectiveness from prior studies. while we do not critique other models, this paper studied the strength and variables of the zero-trust security architecture and attempt to provide an overview of the model and close the knowledge gap on the effectiveness of adopting a Zero trust philosophy.

Zero Trust Architecture in IT Security: Implementing Zero Trust Models to Enhance Security and Reduce Vulnerabilities in Enterprise Networks

Zero Trust Architecture in IT Security, 2023

This article explores the critical need for Zero Trust Architecture (ZTA) in modern enterprise security, driven by the increasing complexities of cyber threats and the limitations of traditional perimeter-based security models. By examining the evolving threat landscape, it defines ZTA as a paradigm shift that emphasizes continuous verification, least privilege access, and the assumption that threats can originate from both internal and external sources. The core principles of Zero Trust are discussed, outlining how organizations can implement these strategies to protect their assets and data more effectively. This approach not only enhances security by reducing vulnerabilities but also adapts to the growing reliance on remote work and cloud services. The article provides a comprehensive overview of the essential components and steps necessary for deploying Zero Trust models, addressing common challenges and limitations while highlighting the significant benefits for enterprises. Ultimately, it advocates for the adoption of Zero Trust practices as a vital strategy for safeguarding information technology infrastructures against an ever-evolving cyber threat landscape.

The Why and How of adopting Zero Trust Model in Organizations

2021

As organizations move most of their workloads to public cloud and remote work becomes moreprevalent today, enterprise networks become more exposed to threats both from inside and outsidethe organization. The traditional Perimeter Security Model assumes that threats are always from theoutside. It assumes that firewalls, proxies, IDS, IPS and other state-of-the-art infrastructure andsoftware solutions curb most of the cyberattacks. However, there are loopholes in this assumption,which the Zero Trust Model addresses. This paper discusses the Zero Trust Model and it’s mandatesand evaluates the model based on the various implementations by the leading industry players likeGoogle and Microsoft.

Zero Trust Cybersecurity: Procedures and Considerations in Context

Encyclopedia, 2024

In response to the increasing complexity and sophistication of cyber threats, particularly those enhanced by advancements in artificial intelligence, traditional security methods are proving insufficient. This paper explores the zero trust cybersecurity framework, which operates on the principle of "never trust, always verify" to mitigate vulnerabilities within organizations. Specifically, it examines the applicability of zero trust principles in environments where large volumes of information are exchanged, such as schools and libraries, highlighting the importance of continuous authentication, least privilege access, and breach assumption. The findings highlight avenues for future research that may help preserve the security of vulnerable organizations.

Zero Trust Model - Never trust, always verify

scip Labs, 2019

The term Zero Trust was coined in 2010 by Forrester Research. the zero trust model addresses the fact that the efforts of conventional perimeter security can no longer provide adequate protection. it redefines the architecture inside of the organizational boundary and adopts a data centric approach. Zero Trust denotes a security architecture model and not a certain technology.

Zero Trust in the Cloud: Implementing Zero Trust Architecture for Enhanced Cloud Security

ESP Journal of Engineering & Technology Advancements , 2022

One of the innovations making organizations experiment with new ways of storing and processing their information is cloud computing; it presents them with both the chance and the threat. Limitations of conventional security models of perimeter protection that are based on the assumption of the security of all devices inside the network are also becoming critical under the conditions of active cyber threats and the sharing of cloud environments. There is a more recent and rather comprehensive approach called Zero Trust Architecture or Zero Trust Extended or Zero Trust Tourism commonly referred to by its mantra of never trust, always verify. Zero Trust refers to a security model that has gained popularity and is used in cloud environments to provide improved security through the enforcement of identity verification, monitoring, and segmentation. This paper starts with a description of the Zero Trust model strategy and its key principles, as well as a comparison with the conventional security strategies. It then drills down and gives a concrete look at how unique the cloud and its security problems are by probing into various problems such as the problem of growing access points, problems of visibility and finally the problem of hybrid and multi-cloud. The Literature review on the Zero Trust systems and their implementation in cloud security discusses the recent literature studies and shares the gaps which are targeted by this paper. In the present work, the methodology that has been used to process the issue and start the implementation of Zero Trust groundwork in a cloud environment is described in detail: The selection of the proper technologies, the usage of IAM systems, Micro-segmentation, and Continuous monitoring. They then go further to elaborate on each of the findings to expound on how Zero Trust enhances cloud security threats that are unique to the cloud, compliance, and minimize the attack surface. Lastly, the conclusion presents the research outcomes, the limitations of this research, and the implication for cloud security, as well as the recommendations for the organization that intends to adopt the Zero Trust security model in their cloud infrastructure. Apart from that, the paper presents the threats and risks associated with Zero Trust as well as the pros and cons of its application concerning cloud technology.
