# OCSentinel Beta Deployment
## Ziel
Beta-Pakete werden ausschliesslich an benannte Pilotgeraete verteilt. Der
Stable-Kanal und die vorhandene Stable-NinjaOne-Aufgabe bleiben unveraendert.
## Beta-Aufgabe in NinjaOne
1. Die bestehende Aufgabe `OCSentinel - Installieren und aktualisieren`
duplizieren und eindeutig als `OCSentinel - Beta Pilot` benennen.
2. Das Script `scripts/bootstrap-ocsentinel-ninja.ps1` verwenden.
3. Die Script-Variable `releasechannel` als Text mit dem Wert `beta` anlegen.
4. Webhook und Secret bleiben identisch zum Stable-Task.
5. Die Aufgabe nur einer Pilot-Richtlinie oder explizit ausgewaehlten Geraeten
zuweisen.
Die Stable-Aufgabe verwendet keinen Kanalwert oder den Wert `stable`.
## Passive Ransomware-Beta
Die Beta ist nach der Installation weiterhin deaktiviert. Auf einem
Pilotgeraet wird in `C:\Program Files\OCSentinel\config\ocsentinel-settings.json`
der Wert `ransomwareBetaEnabled` auf `true` gesetzt. Die Auswertung bleibt
passiv, solange `ransomwareBetaAlertingEnabled` auf `false` steht: Hinweise,
Warnungen und kritische Beta-Signale erscheinen im JSON-Report und Dashboard,
veraendern aber keine NinjaOne-Alarmfelder.
Der optionale Datei-Churn-Sensor wird nur mit
`ransomwareFileChurnEnabled: true` aktiviert. Er wertet ausschliesslich bereits
vorhandene Security-Ereignisse 4663 aus, setzt keine Audit-Richtlinie und
aendert keine SACLs. Es werden nur Zaehler sowie Prozessnamen gespeichert und
uebertragen, niemals Datei- oder Freigabenamen. Eine Auswertung ist auf 5.000
Audit-Ereignisse und ein 15-Minuten-Fenster begrenzt; ein gekappter Lauf erzeugt
kein Churn-Signal.
## Rueckfall
1. Die Beta-Richtlinie entfernen oder die Beta-Aufgabe nicht mehr ausfuehren.
2. Auf den Pilotgeraeten die vorhandene Stable-Aufgabe ausfuehren.
3. Die Ransomware-Beta in der lokalen Konfiguration auf `false` setzen, falls
sie aktiviert wurde.
Der Client prueft weiterhin Paket-Hash und Authenticode-Signaturstatus, bevor
eine Beta installiert wird.
## Pilotprotokoll
Vor dem Start festhalten: Organisation, Geraete, Aktivierungszeit, aktivierte
Feature-Schalter, verantwortliche Person und geplantes Enddatum. Nach dem
Pilot Laufzeit, Upload-Volumen, Hinweise und Fehlalarme bewerten.

# Code-Qualitaetsstandard
## Ziel
Der Client soll klein, pruefbar und wartbar bleiben. Kommentare sind keine
zweite Dokumentation und keine Erklaerung fuer selbsterklaerenden Code.
## Kommentarregel
- Kommentare bleiben nur bei Sicherheitsgrenzen, externen API-Eigenheiten,
nicht offensichtlichen Entscheidungen und bewusstem Fehlertoleranz-Verhalten.
- Beschreibende Kommentare direkt neben selbsterklaerenden Anweisungen werden
entfernt.
- Veraltete Kommentare werden im selben Pull Request wie die Codeaenderung
geloescht oder aktualisiert.
- Architektur- und Betriebswissen gehoert in `docs`, nicht in lange
Quellcodekommentare.
## Wiederkehrender Clean-up
Bei jeder Minor-Version wird ein kurzer Wartungsdurchlauf eingeplant:
1. Tote Konfiguration, nicht erreichbare Pfade und doppelte Hilfsfunktionen entfernen.
2. Kommentare gegen den aktuellen Code pruefen und ueberfluessige entfernen.
3. Formatierung und Benennung vereinheitlichen.
4. Release-Build und die relevanten Scan-Szenarien erneut ausfuehren.
## Sicherheitsausnahme
Kommentare, die vor einer unsicheren Aenderung schuetzen, bleiben erhalten.
Beispiele sind TLS-Kompatibilitaet, Secret-Schutz, Upload-Signaturpruefung und
deterministische Lastverteilung.

## Local Schedule And Burst Mode
During a NinjaOne installation or update, OCSentinel stores the device's
NinjaOne organization, location, and device identifiers in its local client
configuration. Scheduled `SYSTEM` scans restore that context before creating a
report, so their uploads remain assigned to the correct organization.
The installer creates two Windows Scheduled Tasks running as `SYSTEM`:
- `OCSentinel Daily Scan`: runs every day at `08:00` and uploads one signed report.
- `OCSentinel Daily Scan`: runs once per day and uploads one signed report.
The installer deterministically assigns each device a stable slot between
`04:00` and `06:59`, derived from its Windows `MachineGuid`. This distributes
a fleet rollout instead of sending all reports at the same time.
- `OCSentinel Burst Check`: runs every five minutes. It performs no scan unless
the NinjaOne device custom field `ocsentinelburst` is enabled.
the NinjaOne device custom field `ocsentinelburst` is enabled. Once enabled,
it scans for two hours and then disables itself automatically.
Create `ocsentinelburst` as a device-level `Checkbox` custom field and allow
automation read access. Set it to `true` for a device to begin the five-minute
burst scans; clear it to stop them. The normal daily scan continues regardless
of the checkbox.

| `ocsentinelburststatus` | Text | `idle`, `active until ...`, or `completed` |
## Upload Reliability And Client Health
If the upload endpoint is temporarily unavailable, the client stores up to 100
signed report payloads locally under `C:\ProgramData\OCSentinel\upload-queue`.
The next scheduled run sends queued payloads before its new report. The local
health state is stored under `C:\ProgramData\OCSentinel\state`.
Create these additional device custom fields in NinjaOne and allow automation
write access:
| Field name | Type | Purpose |
| --- | --- | --- |
| `ocsentineluploadstatus` | Text | `ok`, `queued`, or `unknown` upload state |
| `ocsentinelqueuedreports` | Integer | Reports waiting for delivery |
| `ocsentinellastuploadutc` | Date/Time | Last successful upload time |
| `ocsentinellasterror` | Text | Last upload error, if any |

## Repair Missing NinjaOne Context
NinjaOne exposes `NINJA_ORGANIZATION_ID`, `NINJA_ORGANIZATION_NAME`,
`NINJA_AGENT_MACHINE_ID`, and location values only while an automation runs.
The scheduled OCSentinel task runs later as `SYSTEM`, so those values must be
persisted during an actual NinjaOne automation.
If the console shows `Organisation unbekannt`, create a temporary NinjaOne
PowerShell automation named `OCSentinel - NinjaOne Kontext aktualisieren` and
copy `scripts/refresh-ocsentinel-ninja-context.ps1` into the editor. Run it as
`SYSTEM` in 64-bit PowerShell once against the affected devices or policy.
The script has no script variables and does the following safely:
1. updates the installed client through the stable, version-independent manifest;
2. stores the current NinjaOne organization, location, node, and machine values;
3. starts one signed status scan and upload using that stored context.
Expected output includes `OCSENTINEL_NINJA_CONTEXT=updated`; this is emitted
only after the immediate upload succeeds. Do not run this script from an
interactive PowerShell session, because NinjaOne does not expose the required
environment values there.

# OfficeCom Sentinel Roadmap
## Produktziel
OfficeCom Sentinel erkennt nachvollziehbare Sicherheitsmuster auf Windows-
Endpunkten und Fileservern, ohne den Betrieb zu stoeren. NinjaOne ist fuer
zeitnahe Alerts zustaendig. Die zentrale Plattform sammelt verdichtete
Telemetrie, zeigt die Sicherheitslage je Organisation und erstellt Berichte.
Der Client ersetzt weder G DATA/MXDR noch ein EDR. Er ergaenzt diese Systeme mit
lokaler Korrelation, organisationsuebergreifender Sicht und nachvollziehbaren
Incident-Protokollen.
## Leitplanken
- Wenige aussagekraeftige Signale statt Alarmierung bei Einzelereignissen.
- Die Bewertung muss im JSON-Report und in der Uebersicht nachvollziehbar sein.
- Kein direkter Datenbankzugriff und keine internen Infrastrukturwerte im Client.
- Standardmaessig minimale Last: keine Vollscans, kein globales Dateiauditing,
keine dauerhafte Uebertragung von Rohereignissen.
- Datenminimierung: zentrale Speicherung nur von verdichteten Ereignissen und
Incident-Kontext, nicht von vollstaendigen Dateilisten.
## Beta- und Rollback-Modell
Jede neue Erkennung, Datenart und UI-Aenderung durchlaeuft denselben
reversiblen Lieferweg. Eine Funktion wird nie erstmals auf dem gesamten Bestand
aktiv geschaltet.
### Stufe 0: Spezifikation und lokale Tests
- Zweck, Datenfelder, Bewertung und erwartete Last werden vor dem Coding
dokumentiert.
- Beispielereignisse decken Normalfall, Hinweis, Warnung, kritisch und Fehler
ab.
- Der Client muss bei fehlender neuer Konfiguration das bisherige Verhalten
unveraendert beibehalten.
### Stufe 1: Interne Beta
- Das Paket wird als separater Beta-Release veroeffentlicht; `stable` bleibt
unveraendert.
- Eine neue Funktion ist per Feature-Schalter standardmaessig deaktiviert.
- Die Beta wird nur auf Testgeraeten bzw. einer internen Organisation verteilt.
- Zentrale Auswertung prueft Laufzeit, Upload-Volumen, Fehler und Datenformate.
### Stufe 2: Passiver Kunden-Pilot
- Ausgewaehlte Geraete erhalten die Beta mit aktivierter Funktion im
Beobachtungsmodus.
- Signale erscheinen in Protokoll und Dashboard, loesen aber keine NinjaOne-
Alarmbedingung aus.
- Der Pilot laeuft mindestens eine realistische Arbeitswoche, bei Fileservern
inklusive der normalen Spitzenzeiten.
### Stufe 3: Kontrollierte Alarmierung
- Erst nach Auswertung werden Warnungen fuer eine kleine, benannte Pilotgruppe
an NinjaOne uebergeben.
- Hinweise bleiben weiterhin rein informativ.
- Schwellenwerte, Ausnahmen und Empfaenger werden pro Pilot dokumentiert.
### Stufe 4: Stable-Rollout
- Rollout zuerst je Organisation oder Richtlinie, nicht an alle Kunden zugleich.
- Der Stable-Kanal wird erst nach erfolgreichem Pilot, Review der Datenqualitaet
und Freigabe der Alarmbedingungen aktualisiert.
- Die vorherige Stable-Version bleibt als signiertes Release verfuegbar.
### Rueckfall
- Sofort: Feature-Schalter in der Richtlinie deaktivieren. Der Client bleibt
installiert, sammelt fuer diese Funktion aber nichts mehr.
- Kurzfristig: Pilotgeraete ueber NinjaOne auf die vorherige Stable-Version
zuruecksetzen.
- Zentral: Die Auswertung kann das neue Feld ignorieren; neue JSON-Felder sind
immer optional und muessen abwaertskompatibel bleiben.
- Datenbankaenderungen werden nur additiv eingefuehrt. Loeschende oder nicht
rueckgaengig zu machende Migrationen gehoeren nicht in eine Beta.
### Abbruchkriterien
Ein Pilot wird pausiert und zurueckgesetzt, wenn eines dieser Kriterien eintritt:
- spuerbare Last oder Beeintraechtigung auf einem Kundenserver,
- unkontrolliertes Upload- oder Queue-Wachstum,
- fehlerhafte Organisationszuordnung oder unerwartete personenbezogene Daten,
- mehr als ein unbegruendeter NinjaOne-Alarm im Pilot ohne klare Korrektur,
- fehlende oder nicht nachvollziehbare Incident-Protokolle.
## Ausgangslage: geliefert
- Endpoint-Client mit signiertem Upload und lokaler NinjaOne-Feldaktualisierung.
- N8n- und PostgreSQL-Pipeline mit organisationsbezogener Zuordnung.
- Interne Uebersicht, Empfaengerverwaltung und woechentliche HTML-Berichte.
- Gestaffelte taegliche Uploads sowie Burst-Pruefung.
- Version 1.4.0: Fehlanmeldungen werden in 15-Minuten-Fenstern korreliert.
Einzelne Tippfehler erzeugen keinen Alarm; Anmelde-Bursts und Password
Spraying werden als Warnung oder kritisch bewertet.
## Voraussetzung: 1.4.1 Beta-Auslieferung
- Eigener Beta-Manifest-Pfad neben `release/stable/version.json`.
- Eigene NinjaOne-Aufgabe fuer Pilotgeraete, die ausschliesslich den
Beta-Manifest-Pfad verwendet.
- Stable-Aufgabe bleibt unveraendert und ist zugleich der schnelle Rollback auf
die letzte freigegebene Version.
- Beta-Releases werden in Gitea als Vorabversion markiert und erhalten dieselbe
Paket-Hash-Pruefung wie Stable-Releases.
- Jeder Pilot dokumentiert Geraete, Organisation, aktivierte Feature-Schalter,
Startzeitpunkt und verantwortliche Person.
## Naechster Schwerpunkt: 1.5 Ransomware-Frueherkennung
### 1.5.0: Leichtgewichtiger Fileserver-Sensor
**Lieferumfang**
- Inkrementelle Auswertung statt Dateiscan: Nur neue Prozess- und
Systemereignisse sowie Aenderungszaehler seit dem letzten Pruefpunkt.
- Erkennung hochrelevanter Manipulationen wie Schattenkopie-, Recovery- und
Backup-Loeschbefehle sowie verdaechtiger Verschluesselungswerkzeuge.
- Lokaler Ringpuffer mit aggregierten Datei-Churn-Signalen aus vorhandenen
Datei-Audit-Ereignissen. Die erste Beta wertet Loesch- und Schreibzugriffe
ohne Datei- oder Freigabenamen aus.
- Snapshot der SMB-Sitzungen und des Incident-Kontexts erst bei einer
Auffaelligkeit.
- Verdichtetes Ransomware-Incident-Protokoll fuer n8n und die Uebersicht.
**Bewertung**
- Hinweis: Ein schwaches, isoliertes Signal. Es erscheint in Protokoll,
Uebersicht und Wochenbericht, aber nicht als NinjaOne-Alarm.
- Warnung: Zwei unabhaengige Signale innerhalb eines kurzen Zeitfensters oder
eine veraenderte Canary-Datei.
- Kritisch: Mehrere korrelierte Signale oder eine bestaetigte Schutzmeldung von
G DATA/MXDR zusammen mit auffaelligem Datei-Churn.
**Last- und Datenschutzgrenzen**
- Sensorpruefung hoechstens einmal pro Minute, ausschliesslich inkrementell.
- Kein globales Windows-Dateiauditing und keine globale Sysmon-Dateierstellung.
- Keine Datei-Hashes und keine rekursiven Share-Scans im Normalbetrieb.
- Maximal ein verdichteter Incident-Upload je Fileserver und fuenf Minuten;
gleiche Muster werden lokal zusammengefasst.
- Keine Dateinamen im Standardprotokoll; optionale, begrenzte Detaildaten nur
fuer explizit konfigurierte kritische Freigaben.
**Abnahme**
- Test auf einem produktionsnahen Fileserver mit normaler Benutzerlast.
- Vergleich der Sensorlast vor und nach Aktivierung.
- Nachweis, dass normale Dateiaktivitaet von vielen Benutzern keinen Alert
erzeugt und ein simuliertes Mehrsignal-Szenario korrekt eskaliert.
- Offline-Pufferung, Deduplizierung und Retry des Incident-Protokolls getestet.
- Start als interne Beta gemaess dem Beta- und Rollback-Modell; der Sensor wird
erst nach dem passiven Fileserver-Pilot als NinjaOne-Alarm aktiviert.
### 1.5.1: Tuning und kontrollierter Rollout
- Baseline je Fileserver und Zeitfenster aus mindestens einer Arbeitswoche.
- Konfigurierbare Ausnahmen fuer bekannte Backup-, Scan- und Servicekonten.
- Pilotgruppe mit wenigen Fileservern, Auswertung der Hinweise und Anpassung
der Schwellenwerte vor breiter Verteilung.
- Klare NinjaOne-Conditions fuer Warnung und kritisch; Hinweise bleiben ohne
Ticket- oder Alarmflut.
## Danach: 1.6 Zusaetzliche Sensoren
- Neue lokale Administratoren und auffaellige Gruppenmitgliedschaften.
- RDP- und SMB-Fehlanmeldungen mit Quell- und Konto-Korrelation.
- Sicherheitsrelevante Aenderungen an Diensten, geplanten Aufgaben und
Autostart-Mechanismen.
- Optionaler Import von G DATA-/MXDR-relevanten lokalen Ereignissen, sofern
diese verlaesslich und ohne proprietaere Nebenlast verfuegbar sind.
## Danach: 1.7 Modernes Web GUI und Visualisierung
Das interne Web GUI wird von einer Debug-Ansicht zu einer schnellen,
arbeitsfaehigen Sicherheitsuebersicht weiterentwickelt. Es bleibt intern und
benoetigt keine eigene Anmeldung, solange der Zugriff ueber das bestehende
interne Netz und den Reverse Proxy abgesichert ist.
### Informationsarchitektur
- Startseite mit Sicherheitslage ueber alle Organisationen, aktiven Incidents,
Datenabdeckung und Upload-Gesundheit.
- Organisationsansicht mit Trend, betroffenen Geraeten, offenen Hinweisen und
letzter erfolgreicher Datenerfassung.
- Geraeteansicht mit klarer Risikozusammenfassung, Ereignis-Timeline,
Ransomware-Incident-Protokollen und aufgeklapptem Rohdatenexport fuer die
technische Analyse.
- Berichtsbereich mit Vorschau, Versandstatus, Empfaengerregeln und erneutem
Versand einer Organisation.
### Visualisierung
- Zeitreihe fuer Hinweise, Warnungen und kritische Signale je Organisation.
- Gestapelte Tagesansicht fuer Login-, CVE-, Ransomware- und Sensor-Signale.
- Heatmap fuer auffaellige Zeitfenster statt einer langen, schwer lesbaren
Ereignisliste.
- Abdeckungsansicht: aktive Clients, veraltete Scans, Upload-Fehler und
Geraete ohne Organisationszuordnung.
- Jede Grafik verweist auf die zugrundeliegenden Geraete und Ereignisse; es
gibt keine rein dekorativen Kennzahlen ohne Drill-down.
### Technische Leitplanken
- Responsive fuer Notebook, Tablet und Mobilansicht; barrierearme Kontraste und
klare Statusfarben.
- Datenbankabfragen liefern aggregierte Zeitreihen. Rohdaten werden nur beim
Oeffnen einer Geraete- oder Incident-Ansicht nachgeladen.
- Begrenzte Zeitraeume und serverseitige Pagination verhindern langsame Seiten
bei wachsendem Datenbestand.
- HTML-E-Mails und Weboberflaeche teilen einen konsistenten visuellen Standard,
aber keine fragilen, kopierten CSS-Regeln.
### Beta und Abnahme
- Neue GUI zunaechst unter separatem internen Beta-Pfad neben der bestehenden
Uebersicht bereitstellen.
- Vergleich der neuen Kennzahlen mit den bekannten Rohdaten und Wochenberichten.
- Pilot mit realen Organisationen, insbesondere einer groesseren Fileserver-
Umgebung, vor Umschalten der Standardansicht.
- Zuruecksetzen erfolgt ueber den Reverse Proxy auf die bestehende GUI; Daten
und Empfaengerregeln bleiben dabei unveraendert.
## Danach: 1.8 Betrieb und Auswertung
- Datenqualitaetspruefung fuer unbekannte Organisationen, fehlende Zuordnung
und veraltete Clients.
- Sensor- und Client-Gesundheit in der internen Uebersicht.
- Berichtsvarianten je Empfaengergruppe und nachvollziehbare Versandhistorie.
- Betriebsmetriken fuer Upload-Fehler, Queue-Alter und Incident-Volumen.
## Nicht Bestandteil
- Kein zweiter Antivirus- oder EDR-Agent.
- Keine Blockierung oder automatische Wiederherstellung durch OCSentinel ohne
explizite, separat freigegebene Schutzfunktion.
- Kein zentraler Upload aller Dateioperationen oder kompletter Eventlogs.
## Qualitaet in jedem Release
- Keine neue Erkennung ohne Beispielereignisse, Regressionstest und dokumentierte
Bewertungslogik.
- Jede neue Datenart benoetigt Zweck, Aufbewahrungsregel und Datenschutzpruefung.
- Vor jeder Minor-Version: Code-Clean-up, Abhaengigkeiten pruefen, tote Pfade
entfernen, ueberfluessige Kommentare loeschen und Dokumentation aktualisieren.
- Release erst nach Build, Paket-Hash-Pruefung und einem Test der Update- und
Upload-Strecke.
