How did David Tan secure the payment ledger from unauthorised access?

Question

Accepted Answer

David Tan Employed Multiple Security Measures for the Payment Ledger

David Tan implemented a multi-layered security strategy to safeguard the payment ledger from unauthorised access. This involved keeping the ledger in three separate, password-protected files, each with backup copies, and storing these files across two different USB flash drives. This approach aimed to ensure the ledger's integrity and prevent its contents from being exposed.
Ledger Stored in Multiple Password-Protected Files

The payment ledger was meticulously organised and secured by David Tan. He maintained the ledger in three distinct files, ensuring that each file had a corresponding backup copy. Crucially, all these files were protected by passwords, adding a significant barrier against unauthorised viewing or modification.
Data Distributed Across Separate USB Drives

Further enhancing the security of the ledger, David Tan ensured that the password-protected files were not stored in a single location. Instead, he saved the files across two separate USB flash drives. This decentralised storage strategy meant that even if one USB drive were compromised or lost, the complete ledger data would still be accessible and protected on the other drive.
