DNS sinkholing is a mechanism that can prevent internal network ranges from communicating with a list of IP addresses of known command-and-control domains by returning a false or controlled IP address for those domains. This can reduce the load on the firewall by intercepting the DNS requests before they reach the firewall and diverting them to a sinkhole server. The other options are not relevant or effective for this purpose.

Threat intelligence can be used to identify likely attack scenarios within an organization based on the organization’s specific vulnerabilities, assets, and threat landscape. Threat intelligence can help security teams anticipate and prepare for potential attacks, as well as detect and respond to ongoing attacks more effectively1. Threat intelligence can also provide insights into the threat actors, their motivations, and their tactics, techniques, and procedures (TTPs)2.

A security information and event management (SIEM) system is a tool that collects and analyzes log data from various sources and provides alerts and reports on security incidents and events. A SIEM system can help the IT team to determine which devices are USB enabled by querying the log data for events related to USB device insertion, removal, or usage. The other options are not relevant or effective for this purpose.
