File System Activity
File System Activity events report when a process performs an action on a file or folder.
Attributes
| Caption | Name | Type | Description |
|---|---|---|---|
| Access Mask | access_mask |
Integer | The access mask in a platform-native format. |
| Action | action |
String |
The normalized caption of action_id.
|
| Action ID | action_id |
Integer |
The action taken by a control or other policy-based system leading to an outcome or disposition. Dispositions conform to an action of 1 'Allowed' or 2 'Denied' in most cases. Note that 99 'Other' is not an option. No action would equate to 1 'Allowed'. An unknown action may still correspond to a known disposition. Refer to disposition_id for the outcome of the action.

| Cloud | cloud |
Cloud[] | Describes details about the Cloud environment where the event was originally created or logged. |
| Component | component |
String |
The name or relative pathname of a sub-component of the data object, if applicable. For example:attachment.doc, attachment.zip/bad.doc, or part.mime/part.cab/part.uue/part.doc.
|

Integer |
The confidence of the reported event severity as a percentage: 0%-100%.
|
| Connection Identifier | connection_uid |
String | The network connection identifier. |
| Count | count |
Integer | The number of times that events in the same logical group occurred during the event Start Time to End Time period. |
| Create Mask | create_mask |
String | The original Windows mask that is required to create the object. |
| Data | data |
JSON |
Additional data that is associated with the event.
|
| Device | device |
Device[] | An addressable device, computer system or host. |
| Disposition | disposition |
String | The disposition name, normalized to the caption of the disposition_id value. In the case of 'Other', it is defined by the event source. |
| Disposition ID | disposition_id |
Integer |
Describes the outcome or action taken by a security control, such as access control checks, malware detections or various types of policy violations.
|
| Duration | duration |
Long |
The event duration or aggregate time, the amount of time the event covers from start_time to end_time in milliseconds.
|
| End Time | end_time |
Timestamp | The end time of a time period, or the time of the most recent event included in the aggregate event. |
| Enrichments | enrichments |
Enrichment[] |
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:[{"name": "answers.ip", "value": "92.24.47.250", "type": "location", "data": {"city": "Socotra", "continent": "Asia", "coordinates": [-25.4153, 17.0743], "country": "YE", "desc": "Yemen"}}]
|
| File | file |
File[] | The file that is the target of the activity. |
| File Diff | file_diff |
String | File content differences used for change detection. For example, a common use case is to identify itemized changes within INI or configuration/property setting values. |

| Message | message |
String | The description of the event/finding, as defined by the source. |
| Metadata | metadata |
Metadata[] | The metadata associated with the event or a finding. |
| Observables | observables |
Observable[] | The observables associated with the event or a finding. |
| OSINT | osint |
OSINT[] | 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. |
| Raw Data | raw_data |
JSON | The event data as received from the event source. |
| Record ID | record_id |
String | Unique idenifier for the event |
| Severity | severity |
String | The event/finding severity, normalized to the caption of the severity_id value. In the case of 'Other', it is defined by the source. |
| Severity ID | severity_id |
Integer |
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.
|
| Start Time | start_time |
Timestamp | The start time of a time period, or the time of the least recent event included in the aggregate event. |
| Status | status |
String | The event status, normalized to the caption of the status_id value. In the case of 'Other', it is defined by the event source. |
| Status Code | status_code |
String |
The event status code, as reported by the event source. For example, in a Windows Failed Authentication event, this would be the value of 'Failure Code', e.g. 0x18. |
| Status Details | status_detail |
String | The status detail contains additional information about the event/finding outcome. |

|
| Unmapped Data | unmapped |
Unmapped[] | The attributes that are not mapped to the event schema. The names and values of those attributes are specific to the event source. |
