A cloud-based private access system integrates static CMDB data with real-time access telemetry to automate Zero Trust segmentation. Administrators upload CMDB files (e.g., CSV / JSON) describing applications, FQDNs, IPs, ports, protocols, ownership, and priorities. An analytics management service stages and normalizes the data, retrieves reference domain data from an in-memory cache, and queries a telemetry engine to correlate intended configurations with observed usage. The system detects mismatches, over-permissive wildcard access, and auto-discovers non-listed elements such as subdomains, ports, or protocol combinations. It then generates prioritized recommendations to refine wildcard rules, create explicit allow policies, and merge or split application groups. Administrators review, simulate, and approve updates, enabling phased rollout, rollback, auditing, and continuous policy tuning based on evolving user and application behavior.

Implementations for probabilistic wildcard-based DNS resolution are described. A request to validate a first subdomain is received from a domain name system (DNS) service attempting to resolve a DNS request that identifies the first subdomain.

This application discloses an FRP remote access system, method, server, storage medium, and product. The system includes: a master control device, a public network server, and multiple controlled devices. The master control device sends network service request messages to the FRP server on the public network server. A preset field in the network service request message contains a unique identifier for the controlled device; this preset field is a field excluding the HOST field in the network service request message. The FRP server parses the unique identifier of the controlled device from the network service request message, determines the target controlled device based on the unique identifier of the controlled device and the unique identifier contained in the custom domain name of each controlled device, and forwards the network service request message to the target controlled device for accessing the network server on the controlled device. This achieves access to the network server of the target controlled device without using wildcard domain names, reducing software development costs and program development difficulty.
