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 | open, read: /etc/ssl/, /etc/pki/, ~/.pki/nssdb/ | DC0055 File Access |
| auditd:SYSCALL | execve: openssl pkcs12, certutil, keytool | 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 |
|---|---|
PathExclusions | Exempt trusted automated services regularly accessing PKI stores. |
UserContext | Differentiate root/system accounts versus user-level access to key material. |
