Abstract
This thesis presents the design and implementation of AWSH, a secure and scalable remote access platform built on the principles of zero trust network access (ZTNA). The system supports agentless and agent-based targets and addresses the inherent limitations of traditional VPN and base-based solutions. Conventional approaches rely on the assumption that users within the network perimeter are inherently trustworthy, an assumption no longer valid in today's distributed and cloud-native environments. Once authenticated, users typically gain broad network visibility and extensive privileges, increasing the risk of lateral movement and credential compromise. Zero Trust architectures mitigate these risks through continuous verification, least-privilege access, and comprehensive auditability of all access activities.
The objective of this work is to provide a unified framework that ensures secure, auditable, and policy-controlled access to remote targets
