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:EXECVE | Execution of gsettings set org.gnome.login-screen disable-user-list true | DC0064 Command Execution |
| auditd:FILE | Modification of Display Manager configuration files (/etc/gdm3/*, /etc/lightdm/*) | DC0061 File Modification |
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 |

DisplayManagerScope | Specify which Display Managers are in use to minimize noise. |
