Hashing is a detective control because it helps verify data integrity after transmission but does not prevent or correct an issue. It allows the recipient to check if the file was altered but does not stop unauthorized access or modify the data.
When hashing is used on a file, it is considered a preventive control. Preventive controls are designed to stop an incident or violation from occurring. In this case, hashing is used to ensure the integrity of the file by generating a hash value (a fixed-size string of characters) based on the content of the file. If the file is altered in any way, the hash value will change, indicating potential tampering.
The use of hashing in this context is a preventive measure to help prevent unauthorized changes to the confidential file and maintain its integrity during transmission or storage.
