Does SA-SPLICE or the Splunk App for Enterprise Security support certificate-based authentication to TAXII service such as FS-ISAC?

[nyfaisal]

Hi. Does the Splice or Splunk Enterprise Security app support certificate-based authentication to the taxii service such as FS-ISAC? Is there a need to use third-party integrator such as Soltra Edge for FS-ISAC feed, or we can connect splunk directly to it?

Hi nyfaisal --

ES 3.3 currently only supports basic HTTP authentication over HTTP/HTTPS to a TAXII feed. Credentials for the feed can be stored either in the POST Arguments for the Threat Intelligence Download or referenced from the ES Credential Manager. Certificate based authentication to TAXII feeds via the taxii_cert_pem/taxii_cert_key parameters is not yet supported in Enterprise Security.

I get taxii.py" taxii_cert_pem or taxii_cert_key doesn't exists error, even though the pem and key files are located and pointed to in the splice configuration. any troubleshooting steps?

Brian, I have seen the feature in SPLICE to add the pem/key parameters. Does it work for FS-ISAC feeds without using soltra Edge?

Splice and Enterprise Security 3.3 allows you to connect directly to any TAXII feed (it's a standardized protocol) and they have been successfully tested with Soltra Edge.

Regarding Splice, you can configure a certificate based authentication through the parameters taxii_cert_pem and taxii_cert_key.

Which feed should I point to for FS-ISAC?
