Server policies in Sophos are applied to which of the following?

Server policies in Sophos are specifically designed to be applied to servers or server groups. This specialization allows administrators to create tailored security settings that address the unique needs and vulnerabilities associated with server environments. Servers often handle sensitive data and support critical business functions, making it essential to have distinct policies that govern their behavior in a way that aligns with best practices for security and performance.

When server policies are applied, they can enforce security protocols, manage updates, configure firewall settings, and implement anti-malware defenses that are particularly relevant to the servers' roles, whether they are application servers, database servers, or file servers. This targeted approach helps in effectively mitigating risks associated with server deployments and enhances the overall security posture of an organization.

In contrast, other options are not applicable as they relate to different types of devices or categories that do not align with the intent and functionality of server policies in Sophos.
