This session will review Splunk’s two premium solutions - Splunk Enterprise Security (ES) is Splunk's award-winning security intelligence solution that brings immediate value for continuous monitoring across SOC and incident response environments. Splunk UBA is a new technology that applies unsupervised machine learning and data science to solving one of the biggest problems in information security today: insider threat. You’ll learn how Splunk UBA works in tandem with ES, or third-party data sources, to bring significant automated analytical power to your SOC and Incident Response teams.

Editor's Notes
- The Splunk platform consists of multiple products and deployment models to fit your needs. Splunk Enterprise – for on-premise deployment Splunk Cloud – Fully managed service with 100% SLA and all the capabilities of Splunk Enterprise…in the Cloud Splunk Light – log search and analytics for small IT environments Hunk – for analytics on data in Hadoop The products can pull in data from virtually any source to support multiple use cases. Splunk Apps extend and simplify deployments by providing pre-packaged content designed for specific use cases and data types.
- For the purposes of this discussion we’ll be talking about and seeing Splunk ES 4.5 and UBA 3.0, running on top of our current release of Splunk Enterprise 6.5.
- Splunk solutions provide capabilities across the modern security markets – from left to right – Splunk isn’t a traditional SIEM but provides SIEM capabilities via Enterprise Security. Enterprise Security also helps with various compliance regulations, and if you need a more specific approach to PCI we have a separate app just for that. Then we provide various methods for security analytics – nothing in Splunk is set in stone or tied down which is a major advantage over rigid SIEM technology. If you want to hunt through your data and create your own searches for analytics – go right ahead with Core Splunk and ES. If you’d rather have a fully curated, out of the box machine learning driven experience, or also want that – then that’s UBA. We are also finding that customers can and do leverage our platform to analyze for fraud and business risk. And finally, many of our partners are offering managed security services with our platform at the center.
- Enterprise Security is a premium app designed to be used in a SOC or incident response group, and it provides SIEM-like functions on top of the Splunk Enterprise or Splunk Cloud platform.
- UBA is very different – it is a standalone platform and doesn’t necessarily need the Splunk Enterprise platform to do what it does. We expect it to be used by SOC analysts and hunters. It is specifically designed to surface vetted threats about outside attackers and insiders, and it does this with a software appliance based approach.
- Splunk excels at creating a data fabric Machine data: Anything with a timestamp, regardless of incoming format. Throw it all in there! Collect it. Store it in one place. Make it accessible for search/analytics/reporting/alerting. DETECTION NOT PREVENTION! ASSUME BREACH! So we need a place we can go to DETECT attacks. DETECT breaches. DETECT the “weird.” So if you had a place to see “everything” that happened… ….what would that mean for your SOC and IR teams?

- We see Splunk as your security nerve center. Security organizations are moving towards putting Splunk at the center of everything. . There’s literally nothing in your environment today when it comes to data that Splunk cannot either ingest or leverage. Just a few of those categories are shown here – some of them are quite typical, like your proxy and firewall data. Others less so – your internal badge readers and cameras, for example. Or the ability to correlate all of your data artifacts with IOCs from your threat intelligence sources. All in one place, all at scale, all in real time. That doesn’t mean that Splunk is always the first place that people go – sometimes Splunk may be feeding another tool, like a traditional SIEM. But Splunk always ends up being the place to see “all of the detail” and the place where customers can mash up the data between many disparate sources.
- 3.3. 3.0 was the first release done against Splunk 6 and that was a huge step forward – mainly because of the use of CIM and accelerated data models. Unlike other competitive solutions ES is constantly evolving – on average twice a year. Upgrades are pretty seamless. Where does content come from? All of the typical places but most importantly it comes from YOU. We take the best ideas that you give us, and we productize them and make them scalable and supportable. Splunk is more than a product – it is a wide open platform that inspires. None of this is lost in ES – splunk with ES is just as flexible and customizable. And it leverages technology in the core product like mapreduce and data models. You need ES to scale to the security intelligence needs of a huge enterprise? No problem. ES has its own dev team and roadmap, dedicated support individuals, a services practice schooled in it and other complementary infosec. Also lots of training is available.
- Underneath ES, there’s this concept called the Common Information Model….This performs normalization on data so that if we have four different AV solutions, for example, in our environment, we can report on them and analyze them and correlate across all of their data regardless of vendor. So normally when we hear normalization…
- …that’s evil. Normalization=bad because it is difficult to customize and maintain, and brittle. But that applies to schema-based normalization, and with splunk…
- …we apply our normalization at search time. Which means that even if you have some old data lying around that was onboarded incorrectly, or if the format of the data changes suddenly, you can tweak the field extractions underneath the CIM and go on with your life.
- It isn’t just us that thinks some form of data normalization is a good idea, especially for security analytics. If you haven’t checked it out, there’s a fantastic book published recently by three guys that work in the Cisco CSIRT, and they detail their extensive use of Splunk for security analysis. They make a strong point early on in the book about the role of data normalization. They mention that each event generated should have the… -Date and Time -Type of action performed -Subsystem performing the action -Identifiers for the object requesting the action -Identifiers for the object providing the action -Status, outcome, or result of the action So CIM helps us get significant regularity out of similar but disparate data types. Also allows cross-domain correlation like IDS to Vuln.
