A. B. C. D.B.
The most cost-effective way for a small to medium-sized company to block the use of USB devices on its network is by applying a Group Policy Object (GPO).
A GPO is a collection of policy settings that can be applied to users and computers in an Active Directory domain. With a GPO, administrators can enforce a wide range of settings, including security settings, on a large number of computers and users.
In this case, a GPO can be created to restrict access to USB ports on company computers. This can be done by disabling the USB port on the computer BIOS or through software configuration. This prevents users from connecting USB devices to company computers, which can be a potential source of data leakage or infection from malware.
Implementing a Data Loss Prevention (DLP) system, conducting user awareness training, or enforcing an Acceptable Use Policy (AUP) are other measures that can be taken to enhance security, but they may not be as cost-effective as using a GPO to restrict USB access.
A DLP system typically involves purchasing specialized software and hardware, and requires ongoing maintenance and training. User awareness training and enforcing an AUP may also require significant investment in time and resources, and may not be as effective in preventing USB usage as a GPO.
In conclusion, the most cost-effective way for a small to medium-sized company to block the use of USB devices on its network is by applying a GPO.
