CSLB C-33 Painting & DecoratingBusiness and Project ManagementMedium
A painting contractor utilizes a cloud-based accounting software to manage all financial records, including invoices, payroll, and expense tracking. What is the MOST critical security measure the contractor should implement to protect this sensitive data?
- AUsing strong, unique passwords and two-factor authentication (2FA) for all user accounts.
- BEnsuring the software vendor guarantees 100% uptime.
- CStoring physical backup copies of all digital records in a fireproof safe.
- DRegularly changing the office Wi-Fi password.
Show answer & explanationAnswer & explanation
Correct answer: A. Using strong, unique passwords and two-factor authentication (2FA) for all user accounts.
Strong, unique passwords combined with two-factor authentication (2FA) are paramount for protecting cloud-based data. This significantly reduces the risk of unauthorized access even if a password is stolen or compromised, as a second form of verification is required.
Why the other options are wrong
- B. Uptime guarantees relate to software availability, not the security of the data itself from unauthorized access.
- C. Physical backups are good for disaster recovery but don't protect the live, sensitive data within the cloud software from unauthorized digital access.
- D. While good practice, changing Wi-Fi passwords doesn't directly protect access to a cloud-based application itself, which is often accessed from various networks.
