Discussion

Using trusted and recognized IOC sources may detect and prevent systems from becoming compromised. An IOC stream is a series or stream of intel 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 separately manipulated after they are imported.
