Which feature in a Group Policy would help restrict access to certain applications for users?

The appropriate feature in Group Policy to restrict access to certain applications for users is Software Restriction Policies. This feature allows administrators to define a set of rules that determine which software can or cannot run on users' systems. By employing Software Restriction Policies, organizations can effectively control the execution of applications, protecting against unauthorized software that could pose security risks or comply with licensing regulations.

Software Restriction Policies work by identifying applications based on attributes such as path, hash, or certificate, enabling a granular approach toward application control. This is particularly useful in environments where there might be a need to prevent users from inadvertently executing malicious software or unauthorized lists of applications.

In contrast, Password Policies primarily govern user authentication practices, ensuring that passwords meet certain complexity and lifespan criteria. DNS Policies relate to the management of Domain Name System settings, which do not directly affect application access. Network Policies are typically concerned with aspects of connectivity and network access, rather than the approval or restriction of specific software applications. Hence, Software Restriction Policies stand out as the dedicated mechanism for application access control within Group Policy.
