- COSO Framework
- A widely adopted model from the Committee of Sponsoring Organizations that defines internal control across five components: control environment, risk assessment, control activities, information and communication, and monitoring.
- Control Environment
- The organizational culture, tone at the top, and governance structures that set the foundation for all other internal controls.
- Risk Assessment
- The process of identifying events that could prevent an organization from achieving its objectives and evaluating their likelihood and potential impact.
- Control Activity
- A specific policy or procedure designed to prevent or detect a particular risk β such as an approval threshold, reconciliation, or system access restriction.
- Segregation of Duties
- Dividing a transaction process across two or more people so that no single individual can both execute and authorize the same transaction, reducing fraud risk.
- Deficiency
- A gap in the design or operation of a control that reduces the likelihood of preventing or detecting a material misstatement or operational error.
- Material Weakness
- A significant control deficiency β or combination of deficiencies β that creates a reasonable possibility that a material misstatement will not be prevented or detected in time.
- IT General Controls (ITGCs)
- Controls over the IT environment that affect the reliability of data produced by financial systems β including access management, change management, and backup and recovery.
- Monitoring Activities
- Ongoing and periodic evaluations that assess whether internal controls are present and operating effectively over time.
- Tone at the Top
- The ethical culture, commitment to integrity, and control consciousness demonstrated by senior leadership that influences how employees throughout the organization behave.
- Inherent Risk
- The level of risk in a process or account before any controls are applied.
- Residual Risk
- The risk remaining after controls have been applied β the target is for residual risk to fall within the organization's defined risk tolerance.
