LoFP LoFP / this is a strictly behavioral search, so we define \"false positive\" slightly differently. every time this fires, it will accurately reflect the first occurrence in the time period you're searching within, plus what is stored in the cache feature. but while there are really no \"false positives\" in a traditional sense, there is definitely lots of noise. this search will fire any time a new ip address is seen in the **geoip** database for any kind of provisioning activity. if you typically do all provisioning from tools inside of your country, there should be few false positives. if you are located in countries where the free version of **maxmind geoip** that ships by default with splunk has weak resolution (particularly small countries in less economically powerful regions), this may be much less valuable to you.

Cloud Provisioning Activity From Previously Unseen Country

Description

The following analytic detects cloud provisioning activities originating from previously unseen countries. It leverages cloud infrastructure logs and compares the geographic location of the source IP address against a baseline of known locations. This activity is significant as it may indicate unauthorized access or potential compromise of cloud resources. If confirmed malicious, an attacker could gain control over cloud assets, leading to data breaches, service disruptions, or further infiltration into the network.

Cloud Provisioning Activity From Previously Unseen City

Description

The following analytic detects cloud provisioning activities originating from previously unseen cities. It leverages cloud infrastructure logs and compares the geographic location of the source IP address against a baseline of known locations. This activity is significant as it may indicate unauthorized access or misuse of cloud resources from an unexpected location. If confirmed malicious, this could lead to unauthorized resource creation, potential data exfiltration, or further compromise of cloud infrastructure.

Cloud Provisioning Activity From Previously Unseen Region

Description

The following analytic detects cloud provisioning activities originating from previously unseen regions. It leverages cloud infrastructure logs to identify events where resources are started or created, and cross-references these with a baseline of known regions. This activity is significant as it may indicate unauthorized access or misuse of cloud resources from unfamiliar locations. If confirmed malicious, this could lead to unauthorized resource creation, potential data exfiltration, or further compromise of cloud infrastructure.

AWS Cloud Provisioning From Previously Unseen Region

Description

This search looks for AWS provisioning activities from previously unseen regions. Region in this context is similar to a state in the United States. Provisioning activities are defined broadly as any event that begins with “Run” or “Create.” This search is deprecated and have been translated to use the latest Change Datamodel.
