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:FILE | /home/*/.mozilla/firefox/*/logins.json OR /home/*/.config/google-chrome/*/Login Data | DC0055 File Access |
| auditd:SYSCALL | ptrace attach | DC0035 Process Access |
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.
