What is the safest way for an admin to test Cortex XDR's ability to protect users from a known flash player exploit?

Creating a non-production Cortex XDR test environment with the weaponized flash file is the safest way to assess the protection capabilities against the known exploit. This approach allows for thorough testing without endangering actual users or production systems. By isolating the testing environment, administrators can effectively evaluate the system’s response to the exploit without the risk of inadvertently compromising the security or functionality of their operational setup. Such a controlled environment ensures that any vulnerabilities can be identified and addressed without exposing employees or sensitive data to potential threats.

This method exemplifies a best practice in IT security testing, as it emphasizes safety, minimizes risk, and promotes a thorough understanding of how the system will respond to real threats.
