A typical desktop workstation used by employees contains software that enables users to access, process, and manage stored data on the organization’s network. This includes operating systems, office applications, business applications, network clients, and access tools. Options A and B describe firewall or gateway functions, not ordinary desktop workstation functions. Option C is incomplete because workstations may process transactions, but the defining feature for most employees is controlled access to network-based resources and stored data. Internal auditors reviewing workstation controls should evaluate endpoint security, patching, access rights, encryption, malware protection, configuration standards, and data loss prevention. Therefore, Option D best describes a typical employee workstation.
