Chapter 7: Information Technology Risks and Controls
Preventive controls prevent errors, omissions, or security incidents from occurring. Examples include antivirus software, firewalls, and intrusion prevention systems.
Detective controls detect errors or incidents that elude preventive controls. For example, a detective control may identify account numbers of inactive accounts or accounts that have been flagged for monitoring of suspicious activities.
Corrective controls correct errors, omissions, or incidents once they have been detected. They vary from simple correction of data-entry errors, to recovery from incidents, disruptions, or disasters.
General controls (also known as infrastructure controls) apply to all systems components, processes, and data for a given organization or systems environment. General controls include, but are not limited to: information security policy, administration, access, and authentication; backup, recovery, and business continuity.
Application controls pertain to the scope of individual business processes or application systems. They include such controls as data edits, transaction logging, and error reporting.

By the area IT control resides, it can be classified as general control or application control.
General controls (also known as infrastructure controls) apply to all systems components, processes, and data for a given organization or systems environment. General controls include, but are not limited to: information security policy, administration, access, and authentication; backup, recovery, and business continuity.
Application controls pertain to the scope of individual business processes or application systems. They include such controls as data edits, transaction logging, and error reporting.
The function of a control is highly relevant to the assessment of its design and effectiveness. Controls may be classified as preventive, detective, or corrective.
Preventive controls prevent errors, omissions, or security incidents from occurring. Examples include antivirus software, firewalls, and intrusion prevention systems.
Detective controls detect errors or incidents that elude preventive controls. For example, a detective control may identify account numbers of inactive accounts or accounts that have been flagged for monitoring of suspicious activities.
Corrective controls correct errors, omissions, or incidents once they have been detected. They vary from simple correction of data-entry errors,, to recovery from incidents, disruptions, or disasters.
Another common classification of controls is by the group responsible for ensuring they are properly implemented and maintained. For the purpose of assessing roles and responsibilities, this guide primarily categorizes IT controls as governance, management, and technical.
