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 | open/write syscalls to block devices (/dev/sd*, /dev/nvme*) | DC0054 Drive Access |
| auditd:EXECVE | Execution of dd, shred, or wipe with arguments targeting block devices | DC0032 Process Creation |
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 |
|---|---|
TargetDevices | Exclude removable drives or designated partitions that may be overwritten during maintenance. |
EntropyThreshold | Tune detection for pseudorandom write patterns to reduce false positives during high-volume I/O. |
