Is it possible to add raw data (user's request) to syslog or exported csv file?

    I'm sending detection events from securesphere to splunk using syslog.

    The syslog settings are:

    CEF:0|Imperva Inc.|SecureSphere|${SecureSphereVersion}|${Alert.alertType}|#cefEscapeMessage(${Alert.alertMetadata.alertName})|${Alert.severity}|act=${Alert.immediateAction} dst=${Event.destInfo.serverIp} dpt=${Event.destInfo.serverPort} duser=#cefEscapeExtension(${Alert.username}) src=${Event.sourceInfo.sourceIp} spt=${Event.sourceInfo.sourcePort} proto=${Event.sourceInfo.ipProtocol} rt=#arcsightDate(${Alert.createTime}) cat=Alert cs1=#cefEscapeExtension(${Rule.parent.displayName}) cs1Label=Policy cs2=#cefEscapeExtension(${Alert.serverGroupName}) cs2Label=ServerGroup cs3=#cefEscapeExtension(${Alert.serviceName}) cs3Label=ServiceName cs4=#cefEscapeExtension(${Alert.applicationName}) cs4Label=ApplicationName cs5=#cefEscapeExtension(${Alert.description}) cs5Label=Description

    The logs received from splunk are: CEF:0|Imperva Inc.|SecureSphere|13.6.0|Protocol|Illegal Parameter Encoding|Low|act=None dst= dpt=80 duser=n/a src= spt=53387 proto=TCP rt=2023/01/21 17:51:05/08/30 14:48:37 cat=Alert cs1=HTTP/1.x Protocol Policy cs1Label=Policy cs2=Server_Zone_2 cs2Label=ServerGroup cs3=Service_Zone_2 cs3Label=ServiceName cs4=Default Web Application cs4Label=ApplicationName cs5="Multiple Nuclei Scanner(+)" cs5Label=Description

    When analyzing an attack, this information is sometimes lacking.

    Actually securesphere logs more information like url, parameter, header.

    GET/setup.cgi?next_file=netgear.cfg&todo=syscmd&cmd=[attack command]   HTTP/1.0

    If the above information were included in the syslog, the analysis would be much more helpful.

    I wonder if such a setup is currently possible in securesphere.

    If I can't do it via syslog, is there another way? Exporting the detection log to csv did not confirm this information.

    I look forward to your reply.

    thank you.

    You can add those fields by customizing the syslog output. What you are looking for is the placeholders to add the needed values.

    Please reference these two documentations :

    1. v14.x Standard Placeholders
    2. v13.6 Standard Placeholders (File says DAM but it includes WAF placeholders)
