has been identified as the source
of a DDoS attack 还会检测ddos source和target
DDoS Target: Indicates that a host
as been identified as a the target of
a DDoS attack.
Data Hoarding: Indicates that a
source or target host within a network
has downloaded an unusual amount
of data from one or more hosts.
Exfiltration: Tracks inside and
outside hosts to which an abnormal
amount of data has been
transferred. 内外通信的网络流量异常
