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 | mount or losetup commands creating hidden or encrypted FS | DC0061 File Modification |
| linux:syslog | Sudo or root escalation followed by filesystem mount commands | 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 |
|---|---|
AllowedMountPoints | Whitelist standard mount points to reduce false positives. |
UserContext | Flag root escalation during mount operations. |
