Controls
related to transactions and data within application systems. Application

and manual data entry. Examples of application controls include data
input validation, agreement of batch totals and encryption of data
transmitted |
| Application

integrated set of computer programs designed to serve a well-defined
function and having specific input, processing, and output activities
(e.g., general ledger, manufacturing resource planning, human resource
management). |

function's responsibility, authority to review records, and accountability. |

Controls,
other than application controls, that relate to the environment within

include the development and implementation of an IT strategy and an
IT security policy, the organization of IT staff to separate conflicting
duties and planning for disaster prevention and recovery. |
