Log format for IOC and BIOC issues ↗
Cortex XSIAM logs IOC and BIOC issues. If you configure Cortex XSIAM to forward logs in the legacy format, when issue logs are forwarded from Cortex XSIAM, each log record has the following format:

Additional fields for BIOC and IOC issue logs
| Field Name | Description |
|---|---|
| /severity | Severity assigned to the issue:
|
| /alert_source | Source of the issue: BIOC or IOC |
| /local_insert_ts | Date and time when Cortex XSIAM – Investigation and Response ingested the app. |
| /source_insert_ts | Date and time the issue was reported by the issue source. |
| /alert_name | If the issue was generated by Cortex XSIAM – Investigation and Response, the issue name will be the specific Cortex XSIAM rule that created the issue (BIOC or IOC rule name). If from an external system, it will carry the name assigned to it by Cortex XSIAM . |
| /alert_category | Issue category based on the issue source.
|
| /alert_description | Text summary of the event including the issue source, issue name, severity, and file path. For alerts generated by BIOC and IOC rules, Cortex XSIAM displays detailed information about the rule. |
| /bioc_indicator | A JSON representation of the rule characteristics. For example: [{""pretty_name"":""File"",""data_type"":null,
""render_type"":""entity"",""entity_map"":null},
{""pretty_name"":""action type"",
""data_type"":null,""render_type"":""attribute"",
""entity_map"":null},{""pretty_name"":""="",
""data_type"":null,""render_type"":""operator"",
""entity_map"":null},{""pretty_name"":""all"",
""data_type"":null,""render_type"":""value"",
""entity_map"":null},{""pretty_name"":""AND"",
""data_type"":null,""render_type"":""connector"",
""entity_map"":null},{""pretty_name"":""name"",
""data_type"":""TEXT"",
""render_type"":""attribute"",
""entity_map"":""attributes""},
{""pretty_name"":""="",""data_type"":null,
""render_type"":""operator"",
""entity_map"":""attributes""},
{""pretty_name"":""*.pdf"",""data_type"":null,
""render_type"":""value"",
""entity_map"":""attributes""}]"
|
| /bioc_category_enum_key | Issue category based on the issue source. An example of a BIOC issue category is Evasion. An example of a Traps issue category is Exploit Modules. |
| /alert_action_status | Action taken by the issue sensor with action status displayed in parenthesis:
|
| /case_id | Unique identifier for the incident. |
| /global_content_version_id | Unique identifier for the content version in which a Palo Alto Networks global BIOC rule was released. |
| /global_rule_id | Unique identifier for an issue generated by a Palo Alto Networks global BIOC rule. |
| /is_whitelisted | Boolean indicating whether the issue is excluded or not. |
