## 2 Related Work  
Research on ZTA has markedly increased in recent years, especially concerning protecting governmental data on the cloud. ZTA concepts, including continuous authentication, MFA (Multi-Factor Authentication), role-based access restriction, and encryption, to safeguard critical government data were analyzed previously [2]. This paper highlights difficulties such as misconfigurations and advocates for dynamic trust-based procedures to avert unwanted access. This study identifies operational problems in ZTA installations for commercial cloud platforms such as Microsoft Azure, particularly for mid-sized companies striving to uphold operational efficiency while ensuring robust security measures. ZTA has been investigated in healthcare and IoT contexts. Healthcare research underscores micro-segmentation, least-privilege access, and the isolation of legacy equipment via proxies or firewalls [3; 4]. Although beneficial for safeguarding healthcare infrastructure, these strategies provide distinct issues when implemented in cloud-native environments like Azure, where hybrid systems and third-party connections add further complexity. IoT networks encounter the problem of protecting numerous resource-constrained devices through micro-segmentation, constant monitoring, and the enforcement of device identity [4]. The technological principles of ZTA in the IoT are pertinent to cloud ZTA; however, the resource limitations and network decentralization inherent in IoT systems complicate direct applicability to Azure. Implementing ZTA principles in the metaverse has been examined, as enabling technologies such as augmented reality (AR), virtual reality (VR), and cloud computing present novel security and privacy problems. Researchers have introduced ZTA models to tackle these difficulties, emphasizing the equilibrium between user experience and robust security mechanisms [5]. The necessity to facilitate real-time user interactions and device mobility renders ZTA implementation in the metaverse unique compared to conventional cloud systems. Nonetheless, these lessons may prove beneficial in Azure contexts where the equilibrium between security and user experience is essential, particularly for apps characterized by high interactivity and multi-user support. Researchers have examined a hybrid approach to ZTA in the banking sector, integrating blockchain technology to provide a more resilient security architecture [6]. The framework emphasizes enhancing data integrity and verification through blockchain technology, which offers immutable records and increased transparency. This research identifies problems, including scalability and operational overhead, analogous to those in Azure ZTA systems, necessitating extensive access policy setups and multi-tenant access controls. This study does not concentrate on the direct integration of blockchain; instead, immutable logging and verifiable identification concepts are pertinent to enhancing auditability and access control in Azure. Quantum methodologies for ZTA have been investigated, utilizing quantum fingerprinting techniques to mitigate MAC spoofing [7]. Although these strategies enhance security, the computational burden and intricacy of integrating quantum systems provide considerable obstacles to deployment. These observations guide the advancement of Azure ZTA, which prioritizes robust authentication techniques like passwordless access and device-based verification. Numerous studies have emphasized the intricacy of implementing Zero Trust Network Architecture (ZTNA) in cloud systems, particularly within hybrid and multi-cloud contexts [8]. The authors have highlighted the operational challenges of fragmented interfaces, continuous monitoring, and the smooth integration of third-party programs. These insights correspond closely with the operational difficulties encountered in Azure ZTA systems, where maneuvering around Azure's multi-service control panels necessitates considerable administrative effort.
