Thanks Hugo.

Have you got details on what you changed and a sample event? I can then look to add this into FortiSIEM.

Thanks again.

Hi Daniel,

Yes, we have added this eventattributes to be recognized:

attrKeyMap attr="resourcePool" key="server_pool_name"
attrKeyMap attr="user" key="user_name"
attrKeyMap attr="httpReferrer" key="http_refer"
attrKeyMap attr="httpVersion" key="http_version"
attrKeyMap attr="signatureSubclass" key="signature_subclass"

The HttpReferrer gives some information that URI Steam don't the raw:

<189>date=2020-10-07 time=14:49:23 log_id=30000000 msg_id=004530004486 device_id=xxxxxxxxxxxxxx vd="root" timezone="(GMT)Greenwich Mean Time: Dublin,Edinburgh,Lisbon,London" type=traffic subtype="http" pri=notice proto=tcp service=https status=success reason=none policy=xxxxxxxxxxxx src=xxxxxxxxxxxxxx src_port=52989 dst=xxxxxxxxxxxx dst_port=443 http_request_time=0 http_response_time=0 http_request_bytes=1690 http_response_bytes=51670 http_method=get http_url="/xxxxxxxxxxxxxxxxxxxx/login" http_agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/xxxxxxxxxxxxxxx Safari/537.36" http_retcode=200 msg="HTTPS get request from xxxxxxxxxxxxxx :52989 to xxxxxxxxxxxxxxxx :443" srccountry="Portugal" content_switch_name="xxxxxxxxxxxxxxxxxxxxx " server_pool_name="xxxxxxxxxx"http_host="xxxxxxxxxxxxx" user_name="Unknown" http_refer="https://xxxxxxxxxxxxxxx/xxxxxxxxxxxxxxxx/transactions" http_version="1.x"

The URI Steam gives: http_url="/xxxxxxxxxxxxxxxxxxxx/login" but a more detailed message on http refer:

server_pool_name="xxxxxxxxxx"
http_host="xxxxxxxxxxxxx"
user_name="Unknown"
http_refer="https://xxxxxxxxxxxxxxx/xxxxxxxxxxxxxxxx/transactions"
http_version="1.x"
