riskDetection resource type

Namespace: microsoft.graph

Represents information about a detected risk in an Azure AD tenant.

Azure AD continually evaluates user risks and app or user sign-in risks based on various signals and machine learning. This API provides programmatic access to all risk detections in your Azure AD environment.

For more information about risk events, see Azure Active Directory Identity Protection.

Note

1. You must have an Azure AD Premium P1 or P2 license to use the risk detection API.
2. The availability of risk detection data is governed by the Azure AD data retention policies.

location	signInLocation	Location of the sign-in.
requestId	String	Request ID of the sign-in associated with the risk detection. This property is null if the risk detection is not associated with a sign-in.
riskDetail	riskDetail	Details of the detected risk. The possible values are: none, adminGeneratedTemporaryPassword, userPerformedSecuredPasswordChange, userPerformedSecuredPasswordReset, adminConfirmedSigninSafe, aiConfirmedSigninSafe, userPassedMFADrivenByRiskBasedPolicy, adminDismissedAllRiskForUser, adminConfirmedSigninCompromised, hidden, adminConfirmedUserCompromised, unknownFutureValue, m365DAdminDismissedDetection. Note that you must use the Prefer: include - unknown -enum-members request header to get the following value(s) in this evolvable enum: m365DAdminDismissedDetection.
riskEventType	String	The type of risk event detected. The possible values are unlikelyTravel, anonymizedIPAddress, maliciousIPAddress, unfamiliarFeatures, malwareInfectedIPAddress, suspiciousIPAddress, leakedCredentials, investigationsThreatIntelligence, generic,adminConfirmedUserCompromised, passwordSpray, impossibleTravel, newCountry, anomalousToken, tokenIssuerAnomaly,suspiciousBrowser, riskyIPAddress, mcasSuspiciousInboxManipulationRules, suspiciousInboxForwarding, and anomalousUserActivity. If the risk detection is a premium detection, will show generic. For more information about each value, see riskEventType values.
riskLevel	riskLevel	Level of the detected risk. Possible values are: low, medium, high, hidden, none, unknownFutureValue.
riskState	riskState	The state of a detected risky user or sign-in. Possible values are: none, confirmedSafe, remediated, dismissed, atRisk, confirmedCompromised, unknownFutureValue.
source	String	Source of the risk detection. For example, activeDirectory.
tokenIssuerType	tokenIssuerType	Indicates the type of token issuer for the detected sign-in risk. Possible values are: AzureAD, ADFederationServices, UnknownFutureValue.
userDisplayName	String	The user principal name (UPN) of the user.
userId	String	Unique ID of the user.
userPrincipalName	String	The user principal name (UPN) of the user.

riskEventType values

Name	UI Display Name	Description
unlikelyTravel	Atypical travel	Identifies two sign-ins originating from geographically distant locations, where at least one of the locations may also be atypical for the user, given past behavior.
anonymizedIPAddress	Anonymous IP address	Indicates sign-ins from an anonymous IP address, for example, using an anonymous browser or VPN.
maliciousIPAddress	Malicious IP address	Indicates sign-ins from a malicious IP address. An IP address is considered malicious based on high failure rates because of invalid credentials received from the IP address or other IP reputation sources.
unfamiliarFeatures	Unfamiliar sign-in properties	Indicates sign-ins with characteristics that deviate from past sign-in properties.
malwareInfectedIPAddress	Malware linked IP address	Indicates sign-ins from IP addresses infected with malware. Deprecated and no longer generated for new detections.
suspiciousIPAddress	Malicious IP address	Identifies logins from IP addresses that are known to be malicious at the time of the sign in.
leakedCredentials	Leaked credentials	Indicates that the user's valid credentials have been leaked. This sharing is typically done by posting publicly on the dark web, paste sites, or by trading and selling the credentials on the black market. When the Microsoft leaked credentials service acquires user credentials from the dark web, paste sites, or other sources, they are checked against Azure AD users' current valid credentials to find valid matches.
investigationsThreatIntelligence	Azure AD threat intelligence	Indicates a sign-in activity that is unusual for the given user or is consistent with known attack patterns based on Microsoft's internal and external threat intelligence sources.
generic	Additional risk detected	Indicates that the user was not enabled for Identity Protection.
adminConfirmedUserCompromised	Admin confirmed user compromised	Indicates that an administrator has confirmed the user is compromised.
passwordSpray	Password spray	Indicates that multiple usernames are attacked using common passwords in a unified brute force manner to gain unauthorized access.
anomalousToken	Anomalous Token	Indicates that there are abnormal characteristics in the token such as an unusual token lifetime or a token that is played from an unfamiliar location.
tokenIssuerAnomaly	Token Issuer Anomaly	Indicates that The SAML token issuer for the associated SAML token is potentially compromised. The claims included in the token are unusual or match known attacker patterns.
suspiciousBrowser	Suspicious browser	Suspicious sign-in activity across multiple tenants from different countries in the same browser.
impossibleTravel	Impossible travel	Discovered by Microsoft Defender for Cloud Apps (MDCA). Identifies two user activities (a single or multiple sessions) originating from geographically distant locations within a time period shorter than the time it would have taken the user to travel from the first location to the second, indicating that a different user is using the same credentials.
newCountry	New country	This detection is discovered by Microsoft Cloud App Security (MCAS). The sign-in occurred from a location that wasn't recently or never visited by the given user.
riskyIPAddress	Activity from anonymous IP address	This detection is discovered by Microsoft Cloud App Security (MCAS). Users were active from an IP address that has been identified as an anonymous proxy IP address.
mcasSuspiciousInboxManipulationRules	Suspicious inbox manipulation rules	Discovered by Microsoft Defender for Cloud Apps (MDCA). Identifies suspicious email forwarding rules, for example, if a user created an inbox rule that forwards a copy of all emails to an external address.
suspiciousInboxForwarding	Suspicious inbox forwarding	This detection is discovered by Microsoft Cloud App Security (MCAS). It looks for suspicious email forwarding rules, for example, if a user created an inbox rule that forwards a copy of all emails to an external address.
anomalousUserActivity	Indicates a suspicious pattern of behavior for a user that is anomalous to past behavioral patterns.

riskReasons values

riskEventType	Value	UI display string
investigationsThreatIntelligence	suspiciousIP	This sign-in was from a suspicious IP address
investigationsThreatIntelligence	passwordSpray	This user account was attacked by a password spray.

Relationships

None.
