What mechanism can organizations use to prevent accidental changes by authorized users?Select one:encryptionSHA-1hashingversion controlbackups

To prevent accidental changes by authorized users, organizations can implement several mechanisms, but among the options provided, version control is the most appropriate choice.

Description of the Options:

1. Encryption: This protects data confidentiality but does not directly prevent changes.

2. SHA-1: This is a cryptographic hash function used for data integrity verification, not specifically for preventing changes.

3. Hashing: Similar to SHA-1, hashing provides integrity checks but does not impose restrictions on changes.

4. Version Control: This system allows multiple versions of a document or file to be maintained. If an accidental change occurs, users can revert to a previous version, thus preventing the impacts of unintended modifications.

5. Backups: While backups can restore data after accidental changes, they are reactive rather than preventive.

Conclusion:

Thus, implementing a version control system is the most effective mechanism for preventing accidental changes by authorized users, allowing organizations to manage and revert changes safely when necessary.
