For this Cybersecurity Exposure Management file, read insider exfil of a customer export against packet captures showing SMB to a previously quiet subnet and write the one fact that would move to isolate a plant for cloud-security architect.

RECOMMENDATION Choose To isolate a plant / Keep production running on this Cybersecurity / Exposure Management packet (insider exfil of a customer export after packet captures showing SMB to a previously quiet subnet).
