Hello,

Just sharing here the small modification to the Splunk TA to extract fields from IPS logs, which changed in the latest version.

In transforms.conf:

[field_extraction_for_agt_security]
# The regular expression consists of repeated shorter regex in below form:
#               (?<FIELD_NAME>[[sep_file_field]])
# All those regex are joined by ",\s*" which is a comma actually.
# The [[sep_file_field]] is referring modular regex "sep_file_field". Refer to Splunk Documentation for detail about modular regex.

REGEX = (?i)(?:[[sep_file_prefix]]),\s*(?<vendor_severity>[[sep_file_field]]),\s*(?<Host_Name>[[sep_file_field]]),\s*(?:Event\sDescription:\s*(?<Event_Description>[[sep_file_field]])),\s*(?:Local:\s*(?<Local_Host_IP>[[sep_file_field]]))?,\s*(?:Local\sHost\sMAC:\s*(?<Local_Host_MAC>[[sep_file_field]]))?,\s*(?:Remote\sHost\sName:\s*(?<Remote_Host_Name>[[sep_file_field]]))?,\s*(?:Remote\sHost\sIP:\s*(?<Remote_Host_IP>[[sep_file_field]]))?,\s*(?:Remote\sHost\sMAC:\s*(?<Remote_Host_MAC>[[sep_file_field]]))?,\s*(?<Traffic_Direction>[[sep_file_field]]),\s*(?<Network_Protocol>[[sep_file_field]]),\s*(?<Hack_Type>[[sep_file_field]]),\s*(?:Begin:\s*(?<Begin_Time>[[sep_file_field]]))?,\s*(?:End:\s*(?<End_Time>[[sep_file_field]]))?,\s*(?:Occurrences:\s*(?<Occurrences>[[sep_file_field]]))?,\s*(?:Application:\s*(?<Application_Name>[[sep_file_field]]))?,\s*(?:Location:\s*(?<Location>[[sep_file_field]]))?,\s*(?<user>[[sep_file_field]]),\s*(?:Domain:\s*(?<Domain_Name>[[sep_file_field]]))?,\s*(?:Local\sPort:\s*(?<Local_Port>[[sep_file_field]]))?,\s*(?:Remote\sPort:\s*(?<Remote_Port>[[sep_file_field]]))?,\s*(?:CIDS\sSignature\sID:\s*(?<CIDS_Signature_ID>[[sep_file_field]]))?,\s*(?:CIDS\sSignature\sstring:\s*(?<CIDS_Signature_String>[[sep_file_field]]))?,\s*(?:CIDS\sSignature\sSubID:\s*(?<CIDS_Signature_SubID>[[sep_file_field]]))?,\s*(?:Intrusion\sURL:\s*(?<Intrusion_URL>[[sep_file_field]]))?,\s*(?:Intrusion\sPayload\sURL:\s*(?<Intrusion_Payload_URL>[[sep_file_field]]))?,?\s*(?:SHA-256:\s*(?<SHA_256>[[sep_file_field]]))?,?\s*(?:MD-5:\s*(?<MD_5>[[sep_file_field]]))?
