3rd Party data source not in Pre-configured

Jump to solution

All,

Newly deployed ESM installation and I am wondering if there is a way to add a 3rd party data source that is not in the pre-configured entries to the system. The data source uses CEF as its logging format.

Thanks, I am actually new to the SIEM so I am still getting comfortable with all of the functions. I will look over the details and go from there. Currently it appears that I have another issue to address before I can take these steps as it is.

Parsing CEF(and JSON) is very simple, you just select the CEF type. The hardest part, with building any parser, even Regex ones is mapping the data to the appropriate fields.

Keeping in mind there are often multiple fields that seem to be the same, but have significantly different performance attributes. Such as indexes, or non-indexed (making searching difficult).

However, mapping something like a 'HTTP response code' to an indexed field will create a very low cardicaility index, and if the query optimizer chooses to use that index, alerts, reports, searches and etc... will significantly slow the platform down.

My suggestion if you are new to building custom parsers make cheat sheet for yourself of all of the database fields. Which ones are index, which ones are not, what datatypes they are, and what database field they are mapped to. It will save many headaches. These fields can be found in the ESM management pages.
