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 |
|---|---|---|
| macos:unifiedlog | execution of security, sqlite3, or unauthorized binaries | DC0032 Process Creation |
| macos:unifiedlog | ~/Library/Application Support/Google/Chrome/*/Login Data OR ~/Library/Application Support/Firefox/*/logins.json | DC0055 File 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.
| Field | Description |
|---|---|
PrivilegedUsers | Expected user context authorized to unlock Keychain or browser databases |
TimeWindow | Correlation window for process execution and credential file access |
