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 |
|---|---|---|
| azure:signinlogs | TokenIssuanceStart, TokenIssuanceSuccess | DC0007 Web Credential Usage |
| m365:unified | login using refresh_token with no preceding authentication context | DC0002 User Account Authentication |
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 |
|---|---|
MFAContextRequired | Customize for accounts where MFA must always precede token issuance |
RefreshTokenReuseThreshold | Threshold for number of times a refresh token is reused without re-auth |
