a misconfigured service account can trigger this alert. a password change on an account used by an email client can trigger this alert. security test cycles that include brute force or password spraying activities may trigger this alert.	t1110 ml elastic

an okta admnistrator may be logged into multiple accounts from the same host for legitimate reasons.	t1110 okta elastic
automated processes that attempt to authenticate using expired credentials and unbounded retries may lead to false positives.	t1110 _deprecated okta aws o365 elastic
based on the high-frequency threshold, it would be unlikely for a legitimate user to exceed the threshold for failed totp code attempts in a short time-span over multiple sessions.	t1110 azure elastic
blocked connection events are generated via an access control policy on the firewall management console. hence no false positives should be present.	t1018 t1046 t1110 t1203 t1595.002 network splunk
build servers and ci systems can sometimes trigger this alert. security test cycles that include brute force or password spraying activities may trigger this alert.	t1078 t1110 ml elastic
expected red team assessments or penetration tests may utilize teamfiltration to evaluate the security posture of azure or microsoft 365 environments. if this is expected behavior, consider adjusting the rule or adding exceptions for specific ip addresses, registered applications, jwt tokens, prts or user	t1069 t1082 t1087 t1110 t1201 t1526 t1580 T1673 azure elastic

false positives may be present. tune okta and tune the analytic to ensure proper fidelity. modify risk score as needed. drop to anomaly until tuning is complete.	t1110 okta tenant splunk
false positives will be limited to the number of events generated by the analytics tied to the stories. analytics will need to be tested and tuned, and the risk score reduced as needed based on the organization.	t1078 t1110 okta tenant splunk

legitimate administrative or security assessment activities may use these user-agents, especially in environments where teamfiltration is employed for authorized audits. if this is expected behavior, consider adjusting the rule or adding exceptions for specific user-agents or ip addresses.	t1069 t1082 t1087 t1110 t1201 t1526 t1580 T1673 azure elastic

misconfigured applications or automated scripts may generate repeated blocked traffic, particularly if attempting to reach decommissioned or restricted resources. vulnerability scanners or penetration testing tools running in authorized environments may trigger this alert. tuning may be required to exclude known internal tools or scanner ips from detection.	t1018 t1046 t1110 t1203 t1595.002 network splunk

multiple account lockouts may be also triggered by an application malfunction. filter as needed, and monitor for any unusual activity.	t1110 okta tenant splunk
security audits may trigger this alert. conditions that generate bursts of failed logins, such as misconfigured applications or account lockouts could trigger this alert.	t1110 ml elastic

the threshold for alert is above 10 attempts and this should reduce the number of false positives.	t1110 o365 tenant splunk
