Turning "Shared key allowed" off refused the key on the endpoints plugin and left four core collector routes open to it. Anything still holding the old key could keep rewriting logged-in user, last boot time, serial number and installed app inventory for ANY hostname, while the admin believed the shared key was off. Data integrity only - no command execution, no credential issuance - but it is a hole in a boundary the product advertises as closed. It cannot simply be closed. Both GE-Enforce reporters still authenticate with that key, so refusing it fleet-wide would stop asset and printer reporting everywhere, and on an air-gapped site mid-migration that is the wrong order of operations. collector.legacysharedkeyrefused therefore DEFAULTS TO TODAY'S BEHAVIOUR, and its description names exactly what turning it on breaks and when it should be turned on: after the reporters move to per-PC credentials, not before. A legacy route used with the shared key now logs a warning, so a site can find out who still depends on the key before flipping anything. On a stock Windows deployment that warning may name the proxy rather than the caller; the token prefix in the same line is the identifier to go by. The switch is seeded with the core defaults and has a control on the authentication settings page. Undeclared, it was a row that did not exist, and this UI has no generic key/value editor, so seeding alone would have rendered nothing for an operator to click. Two contract declarations corrected while in here: notifications.alertscope was declared db.JSON in the model while the migration that creates it ships TEXT, and those migrations state the constraint in their own docstrings: no JSON columns. The model now matches the shipped column rather than the schema being bent to the model. usb and printedparts both import a name that arrived in contract 0.35.0 while declaring core_version floors of 0.1.0 and 0.16.0, so the loader would have accepted them on a core that cannot satisfy them - an ImportError at blueprint registration instead of a refusal with a reason. Both floors now say what the plugin actually needs.
USB plugin - CMMC USB check-in/out database contract
The USB plugin tracks removable-media check-in/out for CMMC compliance. Device
and log state live in a separate, read-write MySQL database (cmmc_usb),
reached with parameterized pymysql via cmmc_usb_connection(). Names of people
are resolved from the HR employee directory (see the employees plugin).
The plugin's own reference tables (usbdevicetypes, usbdevices,
usbcheckouts) live in the main app database; only the live check-in/out data
is in cmmc_usb.
The schema is standardized across sites - the
cmmc_usbcheck-in/out solution is the same deployment everywhere, so the tables below match as-is and no schema adaptation is needed. The database name may differ per site, though - setcmmc_usb_db_name(defaultcmmc_usb) to match the local name. The view recipe at the end is only a fallback for a site that somehow differs. (Contrast the employee directory, which genuinely varies per site.)
Connection
Credentials resolve settings-first, then environment, except the password which is env-only (never stored in the app database).
| Field | Setting key (editable in the setup wizard) | Env var (fallback) |
|---|---|---|
| Host | cmmc_usb_db_host |
CMMC_USB_DB_HOST |
| Database | cmmc_usb_db_name |
CMMC_USB_DB_NAME |
| User | cmmc_usb_db_user |
CMMC_USB_DB_USER |
| Password | (not stored) | CMMC_USB_DB_PASSWORD |
Set the password in .env; the setup wizard's Features step shows the exact
line to paste. This database is read-write - the app account needs
SELECT, INSERT, UPDATE. Engine is MySQL/MariaDB (pymysql).
Required schema
The plugin runs raw SQL against these tables (or views - see below).
devices
| Column | Type | Notes |
|---|---|---|
device_id |
VARCHAR | Primary key; the device serial/tag |
device_desc |
VARCHAR | Description |
device_owner |
VARCHAR | Owner |
status |
VARCHAR | Check-in/out state |
locker_location |
VARCHAR | Where the device is stored |
Operations: SELECT (list + by id), INSERT (register device), UPDATE
(edit fields, change status).
checkinoutlog
| Column | Type | Notes |
|---|---|---|
log_id |
INT (PK) | Auto id |
badge_number |
VARCHAR | Person's badge |
device_id |
VARCHAR | FK to devices.device_id |
action |
VARCHAR | check-in / check-out |
timestamp |
DATETIME | When it happened |
scanned_viruses |
(text/int) | Scan result |
locker_location |
VARCHAR | Locker at time of event |
sanitized |
(bool/int) | Sanitization flag |
Operations: SELECT (history per device), INSERT (log an event).
users
| Column | Type | Notes |
|---|---|---|
badge_number |
VARCHAR | Primary key; the scanned badge |
first_name |
VARCHAR | Given name |
last_name |
VARCHAR | Surname |
Operations: SELECT by badge, INSERT (auto-add a badge on first scan).
Employee directory dependency
To turn a scanned badge into a name, the plugin also reads the HR employees
directory (via the employees plugin's connection). A badge shaped 0<digits>BZ
carries a PayNo (the digits); lookups try employees.SSO and employees.PayNo.
See plugins/employees/README.md for that schema and connection.
Adapting a different site schema (recommended: views)
Sites whose USB-tracking database uses different table/column names should
create read-only/updatable views named devices, checkinoutlog, and
users that map local columns to the names above. Example:
CREATE VIEW devices AS
SELECT
asset_tag AS device_id,
description AS device_desc,
owner AS device_owner,
state AS status,
storage_bay AS locker_location
FROM usb_assets;
Because the plugin writes to devices/checkinoutlog/users, either make the
views updatable (single-table views usually are) or expose real tables with
these column names. Grant the app account SELECT, INSERT, UPDATE.
Notes:
device_idandbadge_numberare the natural keys the plugin matches on.- If
cmmc_usbis unreachable, USB endpoints return an error and the rest of the app keeps working (the feature degrades, it does not crash the app).
