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:SYSCALL | usermod, groupmod, passwd | DC0010 User Account Modification |
| auditd:PATH | /etc/passwd or /etc/group file write | DC0061 File Modification |
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 |
|---|---|
SudoPath | Common sudo or privilege escalation paths (e.g., `/usr/bin/passwd`). |
ModifiedShellList | Detect if user shell is changed to unusual one (e.g., /bin/sh -> /bin/bash). |
