Exam 5 Flashcards
Identification of Control Activities: Principle 10
recognizes that a major task for an organization is to identify what control activities are desirable for that particular organization .
Identification of Control Activities: Principle 12
discusses the importance of developing policies and procedures to ensure control activities are in place and working .
Isolation
Data, programs, documentation, and information processing facilities should be isolated to protect them from potential hazards (e.g., unauthorized access), and access privileges should be restricted and monitored.
Redundancy
Backup copies of programs and data should be made for security reasons. Critical computations should be repeated as a check on accuracy.
Comparison
Comparisons between data provide a check on accuracy and may signal problems to be investigated.
Assistance
Control problems often result from the inability to handle a job, inadequate training, and lack of ongoing guidance.
Oversight
Supervision of employees, internal audits, and external audits encourage careful work and reduce the likelihood that inappropriate activity will occur. Independent reconciliation and verification activities support this concept.
Accountability
Holding employees accountable for their actions promotes compliance with established control activities (e.g., performance/operating reviews). This also encourages careful work.
Automated Controls
Controls programmed into computer software.
Manual Control Procedures
are weaker in that even in the best control environment, human behavior lacks consistency.
Control Activities
Cannot provide absolute assurance that all risks will be eliminated.
Preventive Controls
A control that deals with or stops potential problems through the controls in place.
Detective Control
A control that provides feedback regarding violations of controls in place.
Corrective Control
A control that remedies a control violation after it has been detected.

Performance reviews
Physical controls
Segregation of duties
Information processing
Performance reviews
Timely performance reviews act as detective control and corrective control.
Used to mitigate risks, reduce costs, reduce customer complaints by responding via social media.
Physical Controls
Devices and measures that protect computer hardware and other assets, such as cash, inventories, securities, fixed assets, mechanical check signers, and signature plates.
Segregation of Duties
A control activity in which authorization of transactions, custody of related assets, and modification or creation of related data and program files (or paper-based records) are segregated so that a single individual cannot both perpetrate and conceal an error or inappropriate activity.
Enforcing vacation
Employees are forced to take vacation days so that one person does not always work on the same task. It is to avoid errors and inappropriate actions.
Cryptography
The process of transforming, or encrypting, data (usually by scrambling) into a “secret code.”
Encryption
A process, typically involving a mathematical encryption algorithm and an encryption key that scrambles data to prevent unauthorized persons from accessing the data.
Digital Signature
Extra data appended to an electronic message which identifies and authenticates the sender.
Repuidation
A customer’s denial that an order was placed for goods or services from a vendor.
Digital Certificate
A form of electronic identification that is issued by a certification authority (CA) after the CA verifies the company participating in e-commerce activities is legitimate.
