28. Which of the following are examples of operational controls that would be appropriate to implement in an environment where financial processing activities occur? (Select two.)
Answer: C,D
Dual control and Mandatory vacations are examples of operational controls in financial processing environments.
Dual control and mandatory vacations are essential operational controls that help mitigate risks in environments where financial processing occurs. These controls ensure that no single individual has complete control over critical financial processes, thereby reducing the likelihood of fraud and errors.
A) Key escrow
Key escrow is a method used to store encryption keys securely, allowing a trusted third party to access them when necessary. While this can be important for data security, it does not directly address operational control in financial processing activities, making it less relevant in this context.
B) Tokenization
Tokenization involves replacing sensitive data with unique identifiers or tokens, which enhances data security. However, it is primarily a data protection mechanism rather than an operational control focused on the management and oversight of financial transactions.
C) Dual control
Dual control is an operational control that requires two individuals to authorize a financial transaction, which significantly reduces the risk of fraud and errors. This practice is crucial in financial environments, as it ensures added scrutiny and accountability in processing activities.
D) Mandatory vacations
Mandatory vacations require employees to take time off from their duties, which helps to detect potential fraud that may be occurring over time. This practice serves as a deterrent against wrongdoing and is an effective operational control in financial processing environments.
E) Access badge readers
Access badge readers are security devices that control entry to physical locations. While important for physical security, they are not operational controls that directly impact the processing of financial activities.
F) Biometrics
Biometric systems use unique physical characteristics for authentication, enhancing security. However, similar to access badge readers, they focus on securing access rather than controlling operational processes within financial transactions.
Conclusion
Dual control and mandatory vacations are critical operational controls that help ensure the integrity and security of financial processing activities. In contrast, options A, B, E, and F, while relevant to security and data protection, do not specifically address the operational oversight needed to prevent fraud or errors in financial transactions. Thus, C and D stand out as the most applicable choices for this context.
