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 call with argv matching known disk enumeration commands (lsblk, parted, fdisk) | DC0032 Process Creation |
| auditd:EXECVE | command line arguments containing lsblk, fdisk, parted | 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 |
|---|---|
TTY_type | Detection can exclude interactive TTY sessions to reduce false positives from admin usage |
shell_parent | Differentiate between interactive user shells vs. script-based execution |
