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 | chmod, execve | DC0064 Command Execution |
| auditd:SYSCALL | execve | 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 |
|---|---|
UserContext | Track execution of setuid binaries where UID != EUID or executed from unexpected user context |
FilePathScope | Restrict detection to non-standard locations (e.g., /tmp, /home/*, /var/tmp) |
TimeWindow | Time delta between chmod setting setuid/gid and process execution to define a suspicious window |
