What does “sandboxing” mean in relation to firewall security?

In the context of firewall security, "sandboxing" refers specifically to isolating programs in a controlled environment to monitor their behavior. This technique creates a secure and controlled space where potentially harmful software can be executed without risking the security of the main system. By running applications or files in a sandbox, security professionals can observe their actions and determine if they exhibit malicious behavior without compromising the entire network or system.

This method is particularly useful for analyzing unknown or suspicious files, as it enables organizations to identify threats before they can affect critical systems or data. Sandboxes can detect malware tactics by analyzing how these programs operate, their network requests, and any changes they attempt to make within the system, thereby contributing significantly to proactive security measures. This understanding of suspicious activities helps in timely threat detection and mitigation.
