portfellist

Portfellist is a term used in information technology to denote a structured listing of network ports and their attributes, effectively a catalog or registry of port-based resources within a system or network. It is not a formal standard but a descriptive label commonly found in documentation or tooling to organize port-related information for tasks such as inventory, security auditing, or change management.

The term blends the word port, referring to network ports, with list, indicating an organized enumeration. Variants of the concept appear under names such as port inventory, port registry, or port map. Portfellists can apply across physical and virtual networks, including host machines, containers, and cloud resources, with entries that may link to services, configurations, or metadata relevant to administration and security.

A typical portfellist entry includes core fields such as port number, protocol (TCP or UDP), service name, and status (open, closed, filtered). Additional metadata may cover the owner or responsible team, last modified date, and notes. Some implementations expand the dataset to include security policy references, allowed IP ranges, or linked firewall rules to support compliance and incident response efforts.

Implementation approaches vary: portfellists may be stored in asset management systems, spreadsheets, or as configuration artifacts in JSON or YAML used by deployment or monitoring tools. Because there is no universal standard, organizations tailor the structure and terminology to their workflow, integrating portfellist data with broader network maps, service registries, and access controls.
