Which feature restricts applications on a server?

  1. Server Lockdown

  2. Application Whitelisting

  3. Access Control List

  4. System Validation

The correct answer is: Server Lockdown

The feature that restricts applications on a server is Server Lockdown. This technology is designed to enhance security by controlling which applications can run on a server. By enabling Server Lockdown, administrators can establish strict policies that allow only predefined, trusted applications to execute. This reduces the risk of malware and unauthorized software from compromising the server's integrity. In contrast, application whitelisting is specifically focused on creating a list of applications that are permitted to run, which can also restrict application use, but it operates within a broader framework and may not always offer the same level of control and enforcement as Server Lockdown. Access Control Lists (ACLs) pertain more to permissions related to resources and user access rather than application restrictions. System Validation typically relates to checking the integrity and health of the system rather than controlling application execution.
