Abstract

Major corporations' networks have migrated from conventional in-house platforms to third-party-managed cloud platforms, resulting in a hybrid structure. However, the network's security remains inactive, with less responsibility and supervision.

Multiple networks, each with its own set of zones, comprise the standard network security architecture. Each zone is surrounded by a perimeter defence consisting of one or more firewalls. Each zone gives a particular confidence level and offers access to a variety of resources. "Never trust, always verify" is the ethos of a burgeoning alternative architectural method. Everything inside and beyond the barrier is not immediately trusted under this viewpoint.

This study is primarily concerned with comparing the innovative requirement-specific characteristics employed by cutting-edge research models for zero-trust networks. In addition, the article focuses on selecting and implementing features required for future networks, as well as determining the areas covered by infosec standards (i.e.- ISO 27001:2013 and NIST SP-800). In addition, the research study included questionnaires to obtain information from both organizations and end consumers. Finally, a variety of ideas for future study are offered, which businesses might consider when determining implementation strategies for ZTNA, to develop trust-based enterprise networks.
