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 |
|---|---|---|
| linux:syslog | sshd[pid]: Failed password | 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 |
|---|---|
PortScope | Can be tuned to non-standard ports if SSH is moved from default |
UserScope | Filter high-value or restricted users (e.g., root, service) |
AttemptThreshold | Number of consecutive failures before flagging (e.g., >5 in 2 minutes) |
