Veils

Abstract

This paper briefly describes a prototype interface for computer network defense (CND) that has been developed using the cognitive systems engineering (CSE) / ecological interface design (EID) framework. This ecological interface is referred to as VEILS (Versatile Ecological Interface for Lockdown network Security). VEILS supports CND by collecting and integrating network defense information from a variety of sources including intruder detection / protection systems, firewalls, and system logs. VEILS was designed to be consistent with three principles of EID. The innovative displays represent the affordances of the work domain in a manner that is compatible with human visual processes (i.e., direct perception). The capability to specify both information content (different types) and information extent (scope) is supported entirely through intuitive and natural control input including point, click, and drag (i.e., direct manipulation). Finally, interface resources are used to choose alternative viewing perspectives, to highlight functional relationships across displays and to support effective navigation (i.e., visual momentum).
