infoType-Detektoren zum Verfeinern von Scanergebnissen anpassen

Die integrierten infoType-Detektoren von Sensitive Data Protection sind bei der Suche nach gängigen Arten von sensiblen Daten effektiv. Mit den benutzerdefinierten infoType-Detektoren können Sie Ihren eigenen Detektor für vertrauliche Daten vollständig anpassen. Prüfregeln helfen beim Verfeinern der Scanergebnisse, die von Sensitive Data Protection zurückgegeben werden. Erreicht wird dies durch die Änderung des Erkennungsmechanismus eines bestimmten infoType-Detektors.

Wenn Sie weitere Werte aus den Ergebnissen ausschließen oder einschließen möchten, die von einem integrierten infoType-Detektor zurückgegeben werden, können Sie einen neuen benutzerdefinierten infoType von Grund auf erstellen und alle Kriterien definieren, nach denen der Schutz vertraulicher Daten suchen soll. Alternativ können Sie die Ergebnisse verfeinern, die von den integrierten oder benutzerdefinierten Detektoren des Schutzes sensibler Daten gemäß den von Ihnen angegebenen Kriterien zurückgegeben werden. Zu diesem Zweck fügen Sie Inspektionsregeln hinzu, die dazu beitragen können, falsch positive Meldungen zu reduzieren, die Genauigkeit und Trefferquote zu erhöhen oder die Wahrscheinlichkeit bzw. Sicherheit der Scanergebnisse anzupassen.

In diesem Thema wird erläutert, wie Sie mithilfe der beiden Arten von Inspektionsregeln bestimmte Ergebnisse ausschließen oder zusätzliche Ergebnisse hinzufügen können, und zwar anhand von benutzerdefinierten Kriterien, die Sie angeben. Es werden verschiedene Szenarien vorgestellt, in denen Sie möglicherweise einen der vorhandenen infoType-Detektoren ändern möchten.

Die zwei Arten von Prüfregeln sind:

Ausschlussregeln, die helfen, falsche oder unerwünschte Ergebnisse auszuschließen.
Hotword-Regeln, die helfen, zusätzliche Ergebnisse zu erkennen.

Ausschlussregeln

Ausschlussregeln sind in folgenden Situationen nützlich:

Sie möchten doppelte Scanübereinstimmungen in Ergebnissen ausschließen, die durch überlappende infoType-Detektoren verursacht werden. Angenommen, Sie suchen nach E-Mail-Adressen und Telefonnummern, aber Sie erhalten zwei Treffer für E-Mail-Adressen mit Telefonnummern, z. B. "206-555-0764@example.org".
Sie haben falsch positive Meldungen in Ihren Scanergebnissen. Beispielsweise stellen Sie fest, dass die gleiche Pseudo-E-Mail-Adresse (z. B. "example@example.com") oder Pseudo-Domain (z. B. "example.com") ungewöhnlich oft bei einer Suche nach zulässigen E-Mail-Adressen zurückgegeben wurde.
Sie haben eine Liste mit Begriffen, Wortgruppen oder einer Kombination von Zeichen, die Sie aus den Ergebnissen ausschließen möchten.
Sie möchten eine ganze Datenspalte aus den Ergebnissen ausschließen.
Sie möchten Ergebnisse ausschließen, die sich in der Nähe eines Strings befinden, der einem regulären Ausdruck entspricht.

Ausschlussregeln – API-Übersicht

Der Schutz sensibler Daten definiert eine Ausschlussregel im ExclusionRule-Objekt. Geben Sie in ExclusionRule eine der folgenden Optionen an:

Ein Dictionary-Objekt, das eine Liste von Strings enthält, die aus den Ergebnissen ausgeschlossen werden sollen.
Ein Regex-Objekt, das ein Muster für reguläre Ausdrücke definiert. Strings, die dem Muster entsprechen, werden aus den Ergebnissen ausgeschlossen.
Ein ExcludeInfoTypes-Objekt, das ein Array von infoType-Detektoren enthält. Wenn ein Ergebnis mit einem der hier aufgelisteten infoType-Detektoren übereinstimmt, wird dieses Ergebnis aus den Ergebnissen ausgeschlossen.
Ein ExcludeByHotword-Objekt, das Folgendes enthält:
- Ein regulärer Ausdruck, der das Hotword definiert.
- Ein Proximity-Wert, der festlegt, wie nah das Hotword am Ergebnis sein muss.
Wenn sich der Fund in der festgelegten Nähe befindet, wird er aus den Ergebnissen ausgeschlossen. Bei Tabellen können Sie mit diesem Ausschlussregeltyp eine ganze Datenspalte aus den Ergebnissen ausschließen.

Beispielszenarien für Ausschlussregeln

Jedes der folgenden JSON-Snippets veranschaulicht, wie der Schutz sensibler Daten für das jeweilige Szenario konfiguriert wird.

Bestimmte E-Mail-Adresse beim EMAIL_ADDRESS-Detektorscan auslassen

Das folgende JSON-Snippet und der folgende Code in mehreren Sprachen veranschaulichen, wie Sie dem Schutz sensibler Daten mit einem InspectConfig angeben, dass bei einem Scan, der den infoType-Detektor EMAIL_ADDRESS verwendet, keine Übereinstimmung mit "beispiel@beispiel.de" erfolgen soll:

Scanübereinstimmungen auslassen, die den Teilstring "TEST" enthalten

Das folgende JSON-Snippet und der folgende Code in mehreren Sprachen veranschaulichen, wie Sie dem Schutz sensibler Daten mit einem InspectConfig angeben, dass Ergebnisse, die den Token „TEST“ enthalten, aus der angegebenen Liste von infoTypes ausgeschlossen werden sollen:

Beachten Sie, dass hier für "TEST" als Token und nicht als Teilstring gesucht wird. Eine Übereinstimmung gibt es für etwas wie "TEST@email.com" jedoch nicht für "TESTER@email.com". Wenn eine Teilstring-Übereinstimmung gefunden werden soll, verwenden Sie in der Ausschlussregel anstelle eines Wörterbuchs einen regulären Ausdruck.

Scanübereinstimmungen aus einem PERSON_NAME-Detektorscan auslassen, die sich mit einem benutzerdefinierten Detektor überschneiden

In diesem Szenario möchte der Nutzer nicht, dass eine Übereinstimmung aus einem Scan mit dem integrierten PERSON_NAME-Detektor für den Schutz sensibler Daten zurückgegeben wird, wenn diese Übereinstimmung in einem Scan mit dem im ersten Teil des Snippets festgelegten benutzerdefinierten Regex-Detektor ebenfalls gefunden würde.

Das folgende JSON-Snippet der folgende Code in mehreren Sprachen geben sowohl einen benutzerdefinierten Regex-Detektor als auch eine Ausschlussregel im InspectConfig an. Der benutzerdefinierte Regex-Detektor gibt die Namen an, die aus den Ergebnissen ausgeschlossen werden sollen. Die Ausschlussregel gibt an, dass Ergebnisse, die von einem Scan nach PERSON_NAME zurückgegeben würden, aber auch vom benutzerdefinierten Regex-Detektor als Übereinstimmungen gefunden würden, ausgelassen werden. Beachten Sie, dass VIP_DETECTOR in diesem Fall als EXCLUSION_TYPE_EXCLUDE markiert ist, sodass er selbst keine Ergebnisse liefert. Er wirkt sich lediglich auf Ergebnisse aus, die der PERSON_NAME-Detektor liefert.

Übereinstimmungen beim PERSON_NAME-Detektorscan auslassen, die auch bei dem EMAIL_ADDRESS-Detektorscan gefunden werden

Das folgende JSON-Snippet und der folgende Code in mehreren Sprachen veranschaulichen, wie Sie dem Schutz sensibler Daten mit einem InspectConfig angeben, dass nur eine Übereinstimmung zurückgegeben werden soll, wenn sich Übereinstimmungen für den PERSON_NAME-Detektor mit Übereinstimmungen für den EMAIL_ADDRESS-Detektor überschneiden. Dadurch vermeiden Sie, dass eine E-Mail-Adresse wie "james@example.com" sowohl mit dem Detektor PERSON_NAME als auch mit dem Detektor EMAIL_ADDRESS als Übereinstimmung gemeldet wird.

Übereinstimmungen auslassen, die sich in der Nähe eines Strings befinden

Im folgenden Beispiel wird gezeigt, wie Übereinstimmungen mit dem US_SOCIAL_SECURITY_NUMBER-infoType-Detektor ausgeschlossen werden, wenn sich das Wort „SKU“ innerhalb von 10 Zeichen vor oder 10 Zeichen nach dem Ergebnis befindet.

Aufgrund der Ausschlussregel wird 222-22-2222 in diesem Beispiel nicht als mögliche US-Sozialversicherungsnummer klassifiziert.

Ergebnisse in einer ganzen Datenspalte ausblenden

Im folgenden Beispiel wird gezeigt, wie Ergebnisse in einer ganzen Spalte mit tabellarischen Daten ausgeschlossen werden, wenn der Name dieser Spalte mit einem regulären Ausdruck übereinstimmt. Hier werden alle Ergebnisse, die mit dem infoType-Detektor US_SOCIAL_SECURITY_NUMBER übereinstimmen, aus den Ergebnissen ausgeschlossen, wenn sie sich in der Spalte Gefälschte Sozialversicherungsnummer befinden.

In diesem Beispiel wird nur 222-22-2222 zurückgegeben, da sich 111-11-1111 in der Spalte Gefälschte Sozialversicherungsnummer befindet.

Hotword-Regeln

Hotword-Regeln sind in Situationen wie der folgenden nützlich:

Sie möchten die Wahrscheinlichkeitswerte ändern, die Scanübereinstimmungen basierend auf der Nähe der Übereinstimmung zu einem Hotword zugewiesen sind. Beispiel: Sie möchten den Wahrscheinlichkeitswert für Übereinstimmungen mit Namen von Patienten abhängig von der Nähe des Namens zum Wort "Patienten" erhöhen.
Wenn Sie strukturierte, tabellarische Daten prüfen, möchten Sie die Wahrscheinlichkeitswerte ändern, die Übereinstimmungen basierend auf Spaltenüberschriften zugeordnet sind. Beispiel: Sie möchten den Wahrscheinlichkeitswert für US_SOCIAL_SECURITY_NUMBER erhöhen, wenn sich dieser in einer Spalte mit dem Header ACCOUNT_ID findet.

Hotword-Regeln – API-Übersicht

Im InspectionRule-Objekt des Schutzes sensibler Daten geben Sie ein HotwordRule-Objekt an, mit dem die Wahrscheinlichkeit von Ergebnissen innerhalb einer bestimmten Nähe zu Hotwords angepasst wird.

InspectionRule-Objekte werden als "Regelsatz" in einem InspectionRuleSet-Objekt gruppiert, zusammen mit einer Liste von infoType-Detektoren, für die der Regelsatz gilt. Regeln innerhalb eines Regelsatzes werden in der angegebenen Reihenfolge angewendet.

Hotword-Regel – Beispielszenarien

Das folgende Code-Snippet veranschaulicht, wie der Schutz sensibler Daten für das angegebene Szenario konfiguriert wird.

Wahrscheinlichkeit einer PERSON_NAME-Übereinstimmung erhöhen, wenn sich das Hotword "Patient" in der Nähe befindet

Das folgende JSON-Snippet und der Code in mehreren Sprachen veranschaulichen die Verwendung des Attributs InspectConfig, um in einer medizinische Datenbank nach Patientennamen zu suchen. Sie können zwar den in Sensitive Data Protection integrierten infoType-Detektor PERSON_NAME verwenden, dies führt aber dazu, dass Sensitive Data Protection Übereinstimmungen bei allen Personennamen zurückgibt, nicht nur bei Namen von Patienten. Zur Behebung dieses Problems können Sie eine Hotword-Regel einfügen, die in einem bestimmten Zeichenabstand vom ersten Zeichen möglicher Übereinstimmungen nach dem Wort "Patient" sucht. Ergebnissen, die diesem Muster entsprechen, können Sie dann eine Wahrscheinlichkeit von "sehr wahrscheinlich" zuweisen, da sie Ihren speziellen Kriterien entsprechen. Wenn Sie die minimale Likelihood (Mindestwahrscheinlichkeit) innerhalb von InspectConfig auf VERY_LIKELY (sehr wahrscheinlich) festlegen, ist sichergestellt, dass nur Übereinstimmungen mit genau dieser Konfiguration als Ergebnisse geliefert werden.

/**
 * Inspect a string from sensitive data by using a custom hotword
 * Increase the likelihood of a PERSON_NAME match if there is the hotword "patient" nearby. Illustrates using the InspectConfig property for the purpose of scanning a medical database for patient names. You can use Cloud DLP's built-in PERSON_NAME infoType detector, but that causes Cloud DLP to match on all names of people, not just names of patients. To fix this, you can include a hotword rule that looks for the word "patient" within a certain character proximity from the first character of potential matches. You can then assign findings that match this pattern a likelihood of "very likely," since they correspond to your special criteria. Setting the minimum likelihood to VERY_LIKELY within InspectConfig ensures that only matches to this configuration are returned in findings.

Szenario mit mehreren Prüfregeln

Das folgende JSON-Snippet InspectConfig und Code in mehreren Sprachen veranschaulicht die Anwendung von Ausschluss- und Hotword-Regeln. Der Regelsatz dieses Snippets enthält sowohl Hotword-Regeln als auch Regeln für den Wörterbuch- und Regex-Ausschluss. Beachten Sie, dass die vier Regeln in einem Array innerhalb des rules-Elements angegeben sind.

Überlappende infoType-Detektoren

Es ist möglich, einen benutzerdefinierten infoType-Detektor zu definieren, der denselben Namen wie ein integrierter infoType-Detektor hat. Wie in dem Beispiel im Abschnitt "Hotword-Regel – Beispielszenarien" gezeigt, werden beim Erstellen eines benutzerdefinierten infoType-Detektors mit demselben Namen wie ein integrierter infoType alle vom neuen infoType-Detektor erkannten Ergebnisse zu denen vom integrierten Detektor hinzugefügt. Dies gilt nur, solange der integrierte infoType in der Liste der infoTypes im InspectConfig-Objekt angegeben ist.

Wenn Sie neue benutzerdefinierte infoType-Detektoren erstellen, testen Sie sie gründlich auf Beispielinhalt, um sicherzustellen, dass sie wie erwartet funktionieren.
