PH_RULE_ICS_FORTIGATE_Exploitation_of_Remote_Services
Enabled
A FortiGate product has detected an event containing MITRE ICS Technique ID T0866 - Exploitation of Remote Services. Adversaries may exploit a software vulnerability to take advantage of a programming error in a program, service, or within the operating system software or kernel itself to enable remote service abuse.

Correlation
Investigate the source, and determine if the event was legitimate.
If the following pattern or patterns match an ingested event within the given time window in seconds, trigger an incident.
300 seconds
If the following defined pattern/s occur within a 300 second time window.
mitre_ics_event
This is the named definition of the event query, this is important if multiple subpatterns are defined to distinguish them.
This is the query logic that matches incoming events
eventType IN ("FortiGate-ips-signature-50485","FortiGate-ips-signature-50490","FortiGate-ips-signature-50512","FortiGate-ips-signature-50513","FortiGate-ips-signature-50514","FortiGate-ips-signature-50515")
This defines how matching events are aggregated, only events with the same matching attribute values are grouped into one unique incident ID
srcIpAddr,destIpAddr,eventType
This is most typically a numerical constraint that defines when the rule should trigger an incident
COUNT(*) >= 1
This section defines which fields in matching raw events should be mapped to the incident attributes in the resulting incident.
The available raw event attributes to map are limited to the group by attributes and the aggregate event constraint fields for each subpattern
compEventType=mitre_ics_event.eventType,
srcIpAddr=mitre_ics_event.srcIpAddr,
destIpAddr=mitre_ics_event.destIpAddr,
incidentCount=mitre_ics_event.COUNT(*)
