Definition
For DoD information assurance purposes, an automated Information System (AIS) Application. is

"the product or deliverable of an acquisition program. . . . 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)). AIS applications are deployed to enclaves for operations, and have their operational security needs assumed by the enclave."
