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 |
|---|---|---|
| networkdevice:syslog | admin login events | DC0002 User Account Authentication |
| networkdevice:syslog | exec command='monitor capture' | DC0064 Command Execution |
| networkdevice:syslog | config change (e.g., logging buffered, pcap buffers) | DC0085 Network Traffic Content |
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 |
|---|---|
AdminSessionDuration | Tunable alerting threshold for interactive CLI sessions. |
CaptureCommandList | Define set of known capture/debug commands per vendor to flag unexpected usage. |
KEV CVEs whose mapped technique this analytic detects
| CVE | Vendor / product | State |

| CVE-2022-1040 | Sophos Firewall | Mapped |
