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 | Access to /var/lib/sss/secrets/secrets.ldb or .secrets.mkey | DC0055 File Access |
| linux:syslog | Unusual kinit or klist activity | DC0084 Active Directory Credential Request |
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 |
|---|---|
SecretsAccessThreshold | Alert threshold for frequency of access to Kerberos secrets files. |
UnusualServiceAccounts | Baseline accounts normally performing Kerberos requests; anomalies flagged. |
