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 | chattr, rm, shred, dd run on recovery directories or partitions | DC0064 Command Execution |
| auditd:CONFIG_CHANGE | /etc/fstab, /etc/systemd/* | DC0040 File Deletion |
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 |
|---|---|
WatchedFilePaths | Modify to include specific OS backup configs or LVM snapshots |
ShellProcessUser | Restrict detection to root or sudo users |
