Using trusted and recognized indicator of compromise (IOC) sources may detect and prevent systems from becoming compromised. An IOC stream is a series or stream of IOCs that are imported from a vendor based on a subscription service or manually downloaded and placed in a folder. Threat Response can be configured to retrieve the IOC content on a regularly scheduled basis. The items in an IOC stream can be manipulated separately after they are imported.
