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 source | Channel | Data component |
|---|---|---|
| m365:purview | MailItemsAccessed, Search-Mailbox events | DC0038 Application Log Content |
| azure:signinlogs | Suspicious login to cloud mailbox system | DC0067 Logon Session Creation |
| m365:unified | Search-Mailbox, Get-MessageTrace, eDiscovery requests | DC0064 Command Execution |
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.
| Field | Description |
|---|---|
MailAccessVolumeThreshold | Number of emails accessed within time window to flag anomaly. |
OAuthClientIDAllowList | Allows tuning based on known app registrations. |
KeywordSearchFrequency | Flag high volumes of message searches using suspicious patterns. |
LoginGeolocationVariance | Trigger when IP geolocation varies significantly from user's historical profile. |
