Abstract
Enhanced security for Zero Trust networks is provided by SSH-customized tunnel clients/tunnel servers, a catalog service, and loopback address DNS mechanisms. Systems and methods provide Policy Enforcement Point (PEP) layer enhancements, strategically positioning the PEP between the user and the network resource. It manages network traffic flows and provides moderate control granularity, near-real-time enforcement decisions, low overheads, and broad applicability to TCP/IP traffic through modified tunneling implementations of Secure Shell (SSH). Unique use of SSH tunneling is utilized and adapted to selectively filter tunnel requests based on user entitlements, ensuring secure and authorized access to network resources. This method entails detailed assessment of tunneling requests, DNS manipulation, and the use of loopback address space for traffic redirection, all without requiring modifications to client-side applications. The approach significantly enhances network security by controlling access based on continuous verification of user entitlements, addressing the shortcomings of traditional network security models.
