Anomaly log support for CEF

Anomaly log support for CEF

Following is an example of an anomaly log on the FortiGate disk:

date=2016-02-12 time=14:10:42 logid=0720018433 type=anomaly subtype=anomaly level=alert vd="vdom1" severity=critical srcip=192.168.1.183 dstip=192.168.70.184 srcintf="port15" sessionid=0 action=clear_session proto=1 service="icmp/146/81" count=306 attack="icmp_flood" dstport=20882 icmptype=0x92 icmpcode=0x51 attackid=16777316 profile="DoS-policy1" ref="http://www.fortinet.com/ids/VID16777316"

msg="anomaly: icmp_flood, 34 > threshold 25, repeats 306 times" crscore=50 crlevel=critical

Following is an example of an anomaly log sent in CEF format to a syslog server:
