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 |
|---|---|---|
| macos:unifiedlog | Unusual Kerberos TGS-REQ without TGT or anomalous ticket lifetime | DC0088 Logon Session Metadata |
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 |
|---|---|
TicketRequestPatterns | Expected sequence of TGT followed by TGS requests; deviations may indicate forgery. |
TicketLifetime | Expected ticket lifetimes; anomalies may indicate Golden or Silver Tickets. |
