What type of mitigation places a malicious file or application in a safe location for future review or study?

A quarantine setting will place a malicious or suspect file in a safe location and will keep it there until a set timeframe has passed or until an administrator takes action to deal with it. This can allow you to further analyze the file or to restore it if it was an incorrect identification or if the file is needed for another purpose. Containment is used to limit the extent of an incident or attack, isolation keeps a system or device from connecting to or accessing others, and deleting a file wouldn’t keep it around.
