What default action is designed to prevent users from launching unknown applications?

The default action designed to prevent users from launching unknown applications is based on the principle of minimal privilege and security. A "Default Deny" approach means that all applications are blocked from execution unless they have explicitly been allowed or are recognized as safe by the security policy in place. This is an effective strategy for protecting endpoints from potentially harmful software, as it requires that any new or unrecognized application first receive proper approval before it can be executed.

In this context, "Default Deny" works to create a secure environment where only known, trusted applications are permitted to run, significantly reducing the risk of malware or unauthorized applications from being executed by users. Such a policy encourages strict controls and oversight over what can be installed and how endpoints are utilized, leading to enhanced security posture overall.
