Which of the following are examples of sources for events in endpoint security domain dashboards?

In the context of endpoint security, the primary focus is on devices that directly interact with users, such as workstations, notebooks, and point-of-sale systems. These devices are considered endpoints because they are the final touchpoints where users access services, applications, and data. Endpoint security aims to protect these devices from threats, vulnerabilities, and attacks.

Workstations and notebooks are common within enterprise environments, used by employees for daily tasks. Point-of-sale systems are critical in retail settings, and securing these devices is paramount, as they process sensitive payment information. These endpoints generate significant security event data, which is essential for dashboards monitoring endpoint security.

In contrast, while servers, routers, firewalls, mobile devices, mainframes, cloud instances, and virtual machines represent important components of an organization's IT infrastructure, they do not fit the endpoint classification as closely as the devices listed in the correct answer. Although servers and other network devices contribute to an organization’s security posture, they generally fall under network security rather than endpoint security. Therefore, the dashboard relevant to endpoint security focuses primarily on those devices directly used by end-users, reinforcing the appropriateness of the correct choice.
