In EPM, what is the expected outcome when the Default Deny action is enforced?

The Default Deny action in CyberArk Endpoint Privilege Manager (EPM) is a security posture designed to enhance overall system protection by blocking all applications that are not explicitly permitted. When this action is enforced, the system operates under the principle of least privilege, limiting application execution to only those that have been deemed safe and are on an approved list.

This approach significantly reduces the risk of executing unauthorized or potentially harmful applications, as any application that is not recognized by the system will simply be blocked. It creates an environment where only verified applications can be executed, thereby helping to mitigate threats from malware and other security vulnerabilities.

The outcome of only allowing known applications ensures that an organization maintains control over what runs on its endpoints, thereby enhancing security measures and maintaining compliance with various security policies. This makes it critical that organizations establish a comprehensive list of trusted applications to prevent any interruption in business processes while effectively managing security risks.

In contrast, scenarios where all applications are allowed without restriction, where no action is taken, or where all applications are blocked do not align with the functionality of the Default Deny action and would not provide the security framework intended by using EPM.
