What security measure can help to ensure that unauthorized applications do not run on a server?

Creating an application lockdown policy is an effective security measure to ensure that unauthorized applications do not run on a server. This policy defines a whitelist of approved applications that are allowed to execute, thereby preventing any unapproved or potentially harmful software from running. By restricting application execution, the server is less vulnerable to malware, unauthorized access, and other security threats posed by rogue software.

In a server environment, especially where sensitive data is processed or stored, implementing such a policy is crucial for maintaining security and operational integrity. This proactive approach to application control can significantly reduce the attack surface and protect the server from exploitation by malicious actors.
