Application software is the software that processes
business transactions.

The application software could be a payroll system, a
retail banking system, an inventory system, a billing
system or, possibly, an integrated ERP.
Controls, which relate to the business applications
thereby leading to judicial use of the application and are
enforced through the application itself to the end user.

ITGCs may also be referred to as General Computer
Controls which are defined as: Controls, other than
application controls, which relate to the environment within
which computer-based application systems are developed,
maintained and operated, and which are therefore applicable
to all applications.

These are policies and procedures that relate to many
applications and support the effective functioning of
application controls by helping to ensure the continued
proper operation of information systems.

IS Audit and Internal Controls

Editor's Notes

  • #5 Control: It literally means Internal Controls that is present in an business environment. It can be IT Controls or non IT Controls.Design: It refers to the working part of the control which is a summary on paper/blue print. Basically a working model of the control on paper.Operation: Actual performance of the Control is assessed here.Risk: It is the rate at which there is a threat to the business which has arisen from a specific happening/non happening.Process: A set of tasks make a work flow. A set of work flows make a process. A process is controlled by a “Process owner” or “ Function head”. Eg. HR Process, Procurement Process
  • #7 Control Environment The control environment sets the tone of an organization, influencing the control consciousness of its people. It is the foundation for all other components of internal control, providing discipline and structure. Control environment factors include the integrity, ethical values and competence of the entity's people; management's philosophy and operating style; the way management assigns authority and responsibility, and organizes and develops its people; and the attention and direction provided by the board of directors. Risk Assessment Every entity faces a variety of risks from external and internal sources that must be assessed. A precondition to risk assessment is establishment of objectives, linked at different levels and internally consistent. Risk assessment is the identification and analysis of relevant risks to achievement of the objectives, forming a basis for determining how the risks should be managed. Because economic, industry, regulatory and operating conditions will continue to change, mechanisms are needed to identify and deal with the special risks associated with change. Control Activities Control activities are the policies and procedures that help ensure management directives are carried out. They help ensure that necessary actions are taken to address risks to achievement of the entity's objectives. Control activities occur throughout the organization, at all levels and in all functions. They include a range of activities as diverse as approvals, authorizations, verifications, reconciliations, reviews of operating performance, security of assets and segregation of duties. Information and Communication Pertinent information must be identified, captured and communicated in a form and timeframe that enable people to carry out their responsibilities. Information systems produce reports, containing operational, financial and compliance-related information, that make it possible to run and control the business. They deal not only with internally generated data, but also information about external events, activities and conditions necessary to informed business decision-making and external reporting. Effective communication also must occur in a broader sense, flowing down, across and up the organization. All personnel must receive a clear message from top management that control responsibilities must be taken seriously. They must understand their own role in the internal control system, as well as how individual activities relate to the work of others. They must have a means of communicating significant information upstream. There also needs to be effective communication with external parties, such as customers, suppliers, regulators and shareholders.Monitoring Internal control systems need to be monitored--a process that assesses the quality of the system's performance over time. This is accomplished through ongoing monitoring activities, separate evaluations or a combination of the two. Ongoing monitoring occurs in the course of operations. It includes regular management and supervisory activities, and other actions personnel take in performing their duties. The scope and frequency of separate evaluations will depend primarily on an assessment of risks and the effectiveness of ongoing monitoring procedures. Internal control deficiencies should be reported upstream, with serious matters reported to top management and the board.
