For DoD information assurance purposes, an AIS application is the product or deliverable of an acquisition program, such as those described in DoD Directive 5000.1. (reference (u)). An AIS application performs clearly defined functions for which there are readily identifiable security considerations and needs that are addressed as part of the acquisition. An AIS application may be a single software application (e.g., Integrated Consumable Items Support (ICIS)); multiple software applications that are related to a single mission (e.g., payroll or personnel); or a combination of software and hardware performing a specific support function across a range of missions (e.g., Global Command and Control System (GCCS), Defense Messaging System (DMS)).
