Which of the following guarantees that data in a file have not changed?
- Inspecting the modified date of the file
- Encrypting the file with symmetric encryption
- Using stringent access control to prevent unauthorized access
- Creating a hash of the file, then comparing the file hashes
A hashing algorithm can be used to mathematically ensure that data haven’t been changed by hashing a file and comparing the hashes after a suspected change.
