The technician needs to prevent data loss in a laboratory that is not connected to any external networks. This means that any data that is exfiltrated would need to be physically carried out of the laboratory, or potentially transferred via removable storage devices such as USB drives.
To prevent data loss in this scenario, two methods that would be most effective are drive encryption and USB blocker.
Drive encryption is a method of encrypting data stored on a hard drive or other storage device, which requires a password or key to access the data. This helps to prevent unauthorized access to sensitive information if the storage device is lost or stolen. If an attacker were to physically remove a hard drive from a computer in the laboratory, the data on that drive would be inaccessible without the encryption key.
USB blocker is a method of preventing unauthorized access to USB ports on a computer. This can be done through software or hardware controls, which can disable USB ports or limit their functionality. This helps to prevent the use of removable storage devices to exfiltrate data from the laboratory. If an attacker were to attempt to copy sensitive data onto a USB drive, the USB blocker would prevent the transfer.
The other options listed in the question would not be as effective in preventing data loss in a laboratory that is not connected to external networks. A VPN is used to provide secure remote access to a network, which is not relevant in this scenario. A network firewall is used to filter incoming and outgoing network traffic, which is not applicable if the laboratory is not connected to any external networks. File-level encryption provides encryption for individual files, but would not prevent data exfiltration through other means such as USB drives. MFA (Multi-Factor Authentication) is used to provide an extra layer of security for authentication, but would not be relevant in this scenario.
In summary, the two methods that would be most effective in preventing data loss in a laboratory that is not connected to external networks are drive encryption and USB blocker.
