business workflows that occur very occasionally, and involve a business relationship with an organization in a country that does not routinely appear in network events, can trigger this alert. a new business workflow with an organization in a country with which no workflows previously existed may trigger this alert - although the model will learn that the new destination country is no longer anomalous as the activity becomes ongoing. business travelers who roam to many countries for brief periods may trigger this alert.	t1041 t1048 t1071 t1105 t1566 ml elastic
ftp servers should be excluded from this rule as this is expected behavior. some business workflows may use ftp for data exchange. these workflows often have expected characteristics such as users, sources, and destinations. ftp activity involving an unusual source or destination may be more suspicious. ftp activity involving a production server that has no known associated ftp workflow or business requirement is often suspicious.	t1048 _deprecated elastic
irc activity may be normal behavior for developers and engineers but is unusual for non-engineering end users. irc activity involving an unusual source or destination may be more suspicious. irc activity involving a production server is often suspicious. because these ports are in the ephemeral range, this rule may false under certain conditions, such as when a nat-ed web server replies to a client which has used a port in the range by coincidence. in this case, these servers can be excluded. some legacy applications may use these ports, but this is very uncommon and usually only appears in local traffic using private ips, which does not match this rule's conditions.	t1048 _deprecated elastic
legitimate administrative activities such as model inventory management, monitoring dashboards polling model status, automated health checks verifying model availability, ci/cd pipelines validating deployments, development tools inspecting model configurations, or users browsing available models through management interfaces may trigger this detection during normal operations. adjust the threshold based on your environment's baseline activity.	t1048 web application splunk

nated servers that process email traffic may false and should be excluded from this rule as this is expected behavior for them. consumer and personal devices may send email traffic to remote internet destinations. in this case, such devices or networks can be excluded from this rule if this is expected behavior.	t1048 _deprecated elastic

rdp connections may be made directly to internet destinations in order to access windows cloud server instances but such connections are usually made only by engineers. in such cases, only rdp gateways, bastions or jump servers may be expected internet destinations and can be exempted from this rule. rdp may be required by some work-flows such as remote access and support for specialized software products and servers. such work-flows are usually known and not unexpected. usage that is unfamiliar to server or network owners can be unexpected and suspicious.	t1048 t1190 _deprecated elastic
