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 | execve | DC0032 Process Creation |
| auditd:SYSCALL | open, write | DC0061 File Modification |
| linux:cli | Shell history logs | DC0064 Command Execution |
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 |
|---|---|
CommandRegex | Customize for tools seen in environment (e.g., gzip, bzip2, xz) |
SensitivePathList | Specify file paths likely targeted for obfuscation (e.g., /etc/, /home/) |
