Log sources and channels

Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.

Log sourceChannelData component
WinEventLog:SecurityEventCode=5136DC0066 Active Directory Object Modification
WinEventLog:SecurityEventCode=4704DC0010 User Account Modification
WinEventLog:SysmonEventCode=1DC0032 Process Creation

Mutable elements

Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.

FieldDescription
ObjectTypeFocus on `trustedDomain` or `foreignSecurityPrincipal` AD objects in trust containers.
AttributeModifiedMonitor attributes like `trustPartner`, `trustDirection`, `trustType`, `msDS-TrustForestTrustInfo`.
