Content and properties of syslog messages about alerts

Information about each alert is transmitted in a separate syslog category (syslog facility) that is not used by the system to deliver messages from other sources. Information about each alert is transmitted as a separate syslog message in CEF format. If the alert was generated by the Targeted Attack Analyzer module, information about that alert is transmitted as multiple separate syslog messages in CEF format.

The default maximum size of a syslog message about an alert is 32 KB. Messages that exceed the maximum size are truncated at the end.

The header of each syslog message about an alert contains the following information:

  • Format version.

    Current version number: 0. Current field value: CEF:0.

  • Vendor.

    Current field value: AO Kaspersky Lab.

  • Program name.

    Current field value: Kaspersky Anti Targeted Attack Platform.

  • Program version.

    The current value of the field is 5.0.0-5201.

  • Alert type.

    See the table below.

  • Event name.

    See the table below.

  • Alert importance.

    Allowed field values: Low, Medium, High or 0 (for heartbeat messages).

  • Additional information.

    Example:

    CEF:0|AO Kaspersky Lab| Kaspersky Anti Targeted Attack Platform |5.0.0-5201|url_web| URL from web detected|Low|

The body of a syslog message about an alert matches the information about that alert that is displayed in the program web interface. All fields are presented in the format "<key>=<value>". Depending on whether the alert occurred in network traffic or mail traffic, and depending on the technology that generated the alert, various keys may be transmitted in the body of a syslog message. If the value is empty, the key is not transmitted.

The keys, as well as their values contained in a message, are presented in the table below.
