Integration of Third Party Native Alerts

Stellar Cyber's built-in alerts are created from data pathways that leverage raw data collected from all forms of data sources, including third party services and Stellar Cyber’s sensors. You can choose to allow Stellar Cyber's Machine Learning (ML) and Statistical Analysis (SA) to generate alerts based on raw data ingested from third party services. For certain services, you can additionally choose to ingest and integrate alerts that are natively created in those services.

This topic summarizes which third party services and products Stellar Cyber supports for native alert integration and how those alerts are mapped in Stellar Cyber.

Third Party Native Alert Mapping

Stellar Cyber handles each service and product in a custom manner, according to the nature of the incoming data, including third party native alerts and other security events. To view alerts and events from multiple sources in our unified, common platform, Stellar Cyber normalizes and enriches the third party native alerts and security events during the data ingestion process. With ingested, normalized, and enriched third party native alerts and security events, Stellar Cyber further applies ML/SA engines, a direct mapping, or a combination of the two, to create Stellar Cyber alerts mapped to the XDR Kill Chain with additional deduplication to reduce noise and alert fatigue.

Review the following to better understand the native third party alert mapping Stellar Cyber is doing to help you get to the decision points more efficiently:

  • Deduplication:  In mapping third-party native alerts and security events to the XDR Kill Chain, Stellar Cyber uses a variety of methods to identify and eliminate potential duplicates for each applicable alert or event type. In particular, Stellar Cyber identifies a combination of fields and values to be key characteristics and uses those to identify duplicates. An example method is to compare the values in that combination for each new third party native alert; if the same value set occurs within a time threshold, that record is considered a duplicate and only the original record is mapped. This process is a critical mechanism to eliminate noise and reduce alert fatigue.

  • Normalization: A key benefit of Stellar Cyber is standardization of all incoming data sources to a common data model (Interflow record), that includes some fields based on the Elastic Common Schema (ECS). Values from the incoming raw data are mapped into standardized fields in Stellar Cyber. In some cases, the original data field is still saved with the Interflow record.  This normalization allows Stellar Cyber Analytics and Machine Learning to perform complex analysis and identify related events from disparate ingestion sources. Here are examples of normalization:

    • crowdstrike.event.LocalIP is mapped to Stellar Cyber's host.ip field

    • threatInfo.classification is mapped to Stellar Cyber threat field

  • Enrichment: Stellar Cyber's data framework requires certain fields to help identify the data source, the category of data, the type of event, to support scoring calculations and certain other activities. In some cases, the ingested data can be directly mapped into these fields. In other cases, Stellar Cyber generates that data.  Examples of data enrichment are:

    • (No incoming source field) msg_origin.source is created and populated with the vendor name, such as crowdstrike

    • (No incoming source field) msg_origin.category is created and populated with the applicable category for the data type, such as endpoint

    • Incoming data source field crowdstrike.metadata.eventType field exists and its value (such as crowdstrike_detection_summary) is mapped to Stellar Cyber field msg_class

    • Incoming data source field event.technique.name field exists and its value is either mapped directly or algorithmically standardized to populate to Stellar Cyber field xdr.event_name.

    • Populating the xdr_event structure is a key part of enrichment, with Stellar Cyber ensuring that a Tactic, Technique, and Procedure name, and important scores, are present in every Alert record.

Supported Native Third Party Alerts

The table below lists all the services and products for which Stellar Cyber has developed direct integration of third party native alerts, which includes mapping to the Stellar Cyber XDR Kill Chain and adding those alerts to the Alert index. Data not directly mapped is still run through the Stellar Cyber ML/SA pipeline, where applicable. The third party native alerts that are not mapped are ingested and available for creating ATH rules for automatic actions and entry of the result into the Alert index.

Use the table below to identify the data applicable for direct alert mapping, the method of ingestion, and the nature of the mapping.

  • In cases where a value is indicated as Derived, Stellar Cyber assigns a value based on other attributes in the ingested data.

  • Where possible, links to the third party data type format are provided for reference.

Configure ingestion of Bitdefender's Push event for JSON RPC messages to send data to a Stellar Cyber sensor configured to ingest httpjson (port 5200) over TLS.

Of the different record types you can configure to push to Stellar Cyber's httpjson parser, the 11 at left are normalized and enriched as they are added to the Syslog index. The records are evaluated against existing records in the Alert index-- those that do not already exist are directly mapped to the Alert index and XDR Kill chain.  The other records are run through the ML/SA pipeline, which may generate alerts based on those algorithms. The labels assigned to the alert groups at left refer simply to the nature of the key data points for those alerts. Specifically, these data are supplied with the relevant alert description (Bitdefender field in parenthesis):

  • URL-based alerts: event.type (module acronym), host.name (computer_fqdn), host.ip (computer_ip), url

  • IP-based alerts: event.type (module acronym), host.name (computer_fqdn), host.ip (computer_ip), srcip (attack source or source-ip)

  • Threat-based alerts: event.type (module acronym), host.name (computer_fqdn), host.ip (computer_ip), threatName, where threatName varies depending on the record type (malware_name, threatType, detection_threatName, attack_types, aph_type, exploit_type, or target_type)

  • Imposter: A scammer sets up an email address that looks like it is from your company. Then the scammer sends out messages using that email address. This practice is called spoofing, and the scammer is what we call a business email imposter.

  • Malware: Malware is a common cyber attack and an umbrella term for various malicious programs delivered and installed on end-user systems and servers. These attacks are designed to cause harm to a computer, server, or computer network, and are used by cyber criminals to obtain data for financial gain

  • Toad (Telephone-Oriented Attack Delivery): Toad is a type of social engineering attack that lures potential victims to contact fraudulent call centers managed by threat actors in attempts to steal credentials or install malware onto their systems.

  • Spam: Email spam, also known as junk email, refers to unsolicited email messages, usually sent in bulk to a large list of recipients.

VMware Carbon Black Cloud Connector

VMware Carbon Black alerts are assigned a MITRE technique / tactic / procedure (TTP) which is reformatted but otherwise preserved during mapping, except as noted below.

CB Analytics and Device Control:

  • Alerts with a threat_cause_threat_category of NON_MALWARE, NEW_MALWARE, and KNOWN_MALWARE are directly mapped to the Alerts index. The kill_chain_status values (RECONNAISSANCE, WEAPONIZE, DELIVER_EXPLOIT, INSTALL_RUN, COMMAND_AND_CONTROL, EXECUTE_GOAL, BREACH) are preserved and mapped to the Stellar Cyber XDR Kill Chain.

  • Alerts with a threat category value of RISKY_PROGRAM are assigned a Tactic of XDR Malware and Techinque of XDR PUA.

  • Alerts with threat category value of UNKNOWN are run through Stellar Cyber's ML/SA pipeline, to better ascertain the nature of the alert before mapping it to the Alert index. This type is assigned an Tactic of XDR EBA and Technique of XDR Anomaly

Watchlist: This type of alert is considered noisy (generates a large volume of hits), so it is routed through the ML/SA pipeline using our Time Series Analytic and Rare models, along with deduplication, before being mapped to the Alerts index. This type of alert is classified as Tactic: XDR EBA with Technique: XDR Anomaly.

ORIGINAL FIELDS: In addition to the mapping of fields to Stellar Cyber Interflow fields, all of the original fields for this alert type are included in the Interflow record.

Windows Defender Antivirus

(free version only)

Events

Windows Agent Detection Logs ingested from a Windows Agent

These events are ingested to the Stellar Cyber Windows Event index. As of the v4.3.2 release, they are also now processed into the Alerts index. In these logs, multiple events correlate to a single case, such as event_id 1116 (malware detected), one with event_id 1117 (means malware is quarantined). Stellar Cyber manages this, tracking the events to the related case during the mapping process.
