B. Detective control.
A checksum is a form of data validation that involves calculating a value based on the data being transmitted or stored and comparing it to a previously calculated value. It helps detect errors or changes in the data by verifying its integrity during transmission or storage.
Detective controls are designed to identify and alert about errors. Checksums work by verifying the integrity of data. After data is transmitted or stored, the checksum can be recalculated and compared to the original to detect any tampering or corruption.
In contract preventive controls aim to stop incidents before they happen. So checksums help detect issues, not prevent them.
A checksum is a value that represents the number of bits in a transmission message and is used by IT professionals to detect high-level errors within data transmissions. Prior to transmission, every piece of data or file can be assigned a checksum value after running a cryptographic hash function. The answer is B Detective control
Detective controls, on the other hand, are designed to identify and detect risks or issues that have already occurred. They are reactive in nature and help in identifying and investigating incidents or breaches after they have happened.
Therefore, a checksum is considered a preventive control as it acts as a proactive measure to maintain the integrity of data by detecting any changes or corruption before they lead to potential issues or breaches.
