The action taken by a control or other policy-based system leading to an outcome or disposition. An unknown action may still correspond to a known disposition. Refer to disposition_id for the outcome of the action.
The actor object describes details about the user/role/process that was the source of the activity. Note that this is not the threat actor of a campaign but may be part of a campaign.

The CIS Critical Security Controls is a list of top 20 actions and practices an organization’s security team can take on such that cyber attacks or malware, are minimized and prevented.

The compliance object provides context to compliance findings (e.g., a check against a specific regulatory or best practice framework such as CIS, NIST etc.) and contains compliance related details.

The normalized confidence refers to the accuracy of the rule that created the finding. A rule with a low confidence means that the finding scope is wide and may create finding reports that may not be malicious in nature.
When security issues, such as malware or policy violations, are detected and possibly corrected, then disposition_id describes the action taken by the security product.
Group:context
The additional information from an external data source, which is associated with the event or a finding.
For example, add location information for the IP address in the DNS answers:
Group:primary
The normalized impact of the incident or finding. Per NIST, this is the magnitude of harm that can be expected to result from the consequences of unauthorized disclosure, modification, destruction, or loss of information or information system availability.
Indicates that the event is considered to be an alertable signal. Should be set to true if disposition_id = Alert among other dispositions, and/or risk_level_id or severity_id of the event is elevated. Not all control events will be alertable, for example if disposition_id = Exonerated or disposition_id = Allowed.

The Cyber Kill Chain® provides a detailed description of each phase and its associated activities within the broader context of a cyber attack.

The OSINT (Open Source Intelligence) object contains details related to an indicator such as the indicator itself, related indicators, geolocation, registrar information, subdomains, analyst commentary, and other contextual information. This information can be used to further enrich a detection or finding by providing decisioning support to other analysts and engineers.
The policy that pertains to the control that triggered the event, if applicable. For example the name of an anti-malware policy or an access control policy.
Group:classification
The event/finding severity, normalized to the caption of the severity_id value. In the case of 'Other', it is defined by the source.
The normalized identifier of the event/finding severity.
The normalized severity is a measurement the effort and expense required to manage and resolve an event or incident. Smaller numerical values represent lower impact events, and larger numerical values represent higher impact events.
Group:classification
The event/finding type ID. It identifies the event's semantics and structure. The value is calculated by the logging system as: class_uid * 100 + activity_id.
