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 |
|---|---|---|
| auditd:USER_LOGIN | USER_AUTH | 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 |
|---|---|
TimeWindow | Period of brute force activity correlation (e.g., 5 mins) |
IPWhitelist | Exclude known monitoring IPs or jump boxes |
LoginSource | Filter SSH vs. local logins |
