Why is it necessary for sandboxing to analyze suspect files closely?

Sandboxes are essential for analyzing suspect files closely due to their primary function of identifying and reporting malicious behavior. When a file is suspected of being harmful, it is executed in a controlled, isolated environment where its actions can be monitored without risking the wider network or system. By observing how the file interacts with the system—such as attempting to modify files, connect to external servers, or exploit vulnerabilities—security analysts can determine if the file poses a threat.

The analysis focuses on behavioral patterns rather than static characteristics, as malicious files often use various evasion techniques to disguise their true intent. Detecting these behaviors allows for timely responses, improving overall network security and protecting valuable data. Instead of merely verifying a file's metadata or attempting to fix it, understanding its potential threat level is crucial for implementing the appropriate security measures and responses.
