a host failing to authenticate with multiple disabled domain users is not a common behavior for legitimate systems. possible false positive scenarios include but are not limited to vulnerability scanners, multi-user systems missconfigured systems.	t1110 T1110.003 endpoint splunk
a host failing to authenticate with multiple invalid domain users is not a common behavior for legitimate systems. possible false positive scenarios include but are not limited to vulnerability scanners, multi-user systems and missconfigured systems.	t1110 T1110.003 endpoint splunk
a host failing to authenticate with multiple valid domain users is not a common behavior for legitimate systems. possible false positive scenarios include but are not limited to vulnerability scanners and missconfigured systems. if this detection triggers on a host other than a domain controller, the behavior could represent a password spraying attack against the host's local accounts.	t1110 T1110.003 endpoint splunk
a host failing to authenticate with multiple valid users against a remote host is not a common behavior for legitimate systems. possible false positive scenarios include but are not limited to vulnerability scanners, remote administration tools, missconfigyred systems, etc.	t1110 T1110.003 endpoint splunk
a process failing to authenticate with multiple users is not a common behavior for legitimate user sessions. possible false positive scenarios include but are not limited to vulnerability scanners and missconfigured systems.	t1110 T1110.003 endpoint splunk
a single public ip address servicing multiple legitmate users may trigger this search. in addition, the threshold of 5 distinct users may be too low for your needs. you may modify the included filter macro `multiple_okta_users_with_invalid_credentials_from_the_same_ip_filter` to raise the threshold or except specific ip adresses from triggering this search.	t1078 t1078.001 T1110.003 okta tenant splunk
a source ip failing to authenticate with multiple users in a short period of time is not common legitimate behavior.	t1110 T1110.003 T1110.004 t1586 t1586.003 o365 tenant okta tenant splunk
a source ip failing to authenticate with multiple users is not a common for legitimate behavior.	t1110 T1110.003 T1110.004 t1586 t1586.003 azure active directory splunk
a source user failing attempting to authenticate multiple users on a host is not a common behavior for regular systems. some applications, however, may exhibit this behavior in which case sets of users hosts can be added to an allow list. possible false positive scenarios include systems where several users connect to like mail servers, identity providers, remote desktop services, citrix, etc.	t1110 T1110.003 endpoint splunk
a user with successful authentication events from different ips may also represent the legitimate use of more than one device. filter as needed and/or customize the threshold to fit your environment.	t1110 t1110.001 T1110.003 T1535 t1586 aws account azure tenant splunk
an ip address with more than 20 failed authentication attempts in the span of 5 minutes may also be triggered by a broken application.	t1110 T1110.003 T1110.004 aws account splunk
details for the risk calculation algorithm used by identity protection are unknown and may be prone to false positives.	t1110 T1110.003 t1586 t1586.003 azure active directory splunk

this detection may yield false positives in scenarios where legitimate bulk sign-in activities occur, such as during company-wide system updates or when users are accessing resources from varying locations in a short time frame, such as in the case of vpns or cloud services that rotate ip addresses. filter as needed.	t1110 T1110.003 T1110.004 t1586 t1586.003 azure tenant o365 tenant splunk
