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 | syscalls (open, read, ioctl) on /dev/input or /proc/*/fd/* | DC0035 Process Access |
| linux:syslog | dmesg or syslog for module loads | DC0079 Driver Load |
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 |
|---|---|
PathTarget | Can tune based on device paths accessed for keyboard input (e.g., /dev/input/event0) |
UserContext | Exclude root or admin-auth shell sessions if needed |
ModuleWhitelist | Set a known list of allowed kernel modules |
