Abstract

An email account or a syslog receiver are the notification channels through which IOC and BIOC alerts are communicated.

Cortex XSIAM logs IOC and BIOC alerts. If you configure Cortex XSIAM to forward logs in the legacy format, when alert logs are forwarded from Cortex XSIAM, each log record has the following format:

  • Email account: Each field is labeled, one line per field.

    Example 8. 
    edrData/action_country: 
    edrData/action_download: 
    edrData/action_external_hostname: 
    edrData/action_external_port: 
    edrData/action_file_extension: pdf
    edrData/action_file_md5: null
    edrData/action_file_name: XORXOR2614081980.pdf
    ...
    xdr_sub_type: BIOC - Credential Access
    bioc_category_enum_key: null
    alert_action_status: null
    agent_data_collection_status: null
    attempt_counter: null
    case_id: null
    global_content_version_id: 
    global_rule_id: 
    is_whitelisted: false
