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 | setuid or setgid bit changes | DC0059 File Metadata |
| auditd:SYSCALL | execve with UID ≠ EUID | DC0034 Process Metadata |
| auditd:SYSCALL | sudo or pkexec invocation | DC0021 OS API 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 |
|---|---|
WatchedDirectories | Paths where unauthorized setuid binaries may be dropped |
UserContext | Which users are allowed to run sudo/pkexec or modify binaries |
TimeWindow | Duration between file permission change and elevated command execution |
