HOW DO WE GET DATA IN?
Data comes from…
You can actually do this in the sandbox, if you want.
Data Ingest + Common Information Model● You’ve got a bunch of systems…● How to bring in:● Network AV● Windows + OS X AV● PCI-‐zone Linux AV● Network Sandboxing● APT Protection
● CIM = Data Normalization
NORMALIZATION?!?
NORMALIZATION?!?
Relax. This is
therefore, CIM gets applied at SEARCH TIME.
Data Normalization is Mandatory for your SOC
“The organization consuming the data must develop and consistently
use a standard format for log normalization.” – Jeff Bollinger et.
al., Cisco CSIRT
Your fields don’t match? Good luck creating investigative queries
Free. Supported. Fully documented.
Lots of apps support CIM.

The Challenge:• Industry says Threat Intel is
key to APT Protection• Management wants all
threat intel checked against every system, constantly
• Don’t forget to keep your 15+ threat feeds updated
The Solution:

destination) feed…is north of 97% for the feeds we have sampled…”
