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 system calls to ~/.bash_history or /etc/shadow | DC0055 File Access |
| auditd:SYSCALL | execution of tools like cat, grep, or awk on credential files | 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 |
|---|---|
SensitivePaths | Paths to credential files such as /etc/shadow or ~/.bash_history |
UserContext | Whether the process runs under a privileged or non-interactive session |
