Introducing Splunk Enterprise Security 5.2
Generally Available: 16/10/18

© 2018 SPLUNK INC.
Event Sequencing
Define Attacker Techniques via Multiple Matching Events
▶ The Event Sequencing Engine runs as a real-
time search and listens for incoming notable
events and risk modifiers that are triggered by
correlation searches.
▶ Transitions can also be configured to
aggregate notable events or risk modifiers that
may happen after a transition match is found.

Introducing Splunk Phantom Version 4.0
Security Orchestration, Automation, & Response (SOAR) Platform
▶ Clustering support for added performance and redundancy
• Enables Phantom to scale horizontally using additional instances for added performance
and redundancy
▶ Indicator View for threat intelligence style analysis
• Provides a new and important way to visualize security data on the Phantom platform.
Data is presented in the view organized by indicator, versus event, for easier threat-
intelligence style analysis.
▶ Native Splunk search support
• Splunk is now the default search engine shipped with the Phantom product. Users are
able to use their existing or new external Splunk instances to achieve a single source for
security data storage.
Elasticsearch engine remains an external option for those that prefer it.

Introducing Splunk User Behaviour Analytics 4.2
Generally Available: 16/10/18
▶ User Feedback for machine learning
models provides anomaly customization and
improved threat detection accuracy
▶ Improved data ingestion performance by
up to 10x, with the new Splunk-to-Kafka UBA
ingestion connector.
Kafka ingestion does not require UBA to run
real-time indexed search queries on core
Splunk, rather uses micro-batched queries.
▶ Native single-sign-on authentication
support for multiple identity providers Okta,
Microsoft ADFS and Ping Identity

© 2018 SPLUNK INC.
Introducing Splunk ITSI 4.0
Predictive Analytics for Real-Time Insights
▶ KPI Predictions
We’re excited to deliver deeper insights into a
potential health degradation with KPI
Predictions. These utilize the breadth of data in
the platform to help predict KPIs like customer
experience, application workload, and
infrastructure health, in order to identify issues
or outages in advance.
▶ Predictive Cause Analysis
This new feature helps you drill down into the
specific services underlying a predicted issue to
proactively remediate and resolve it before
customer experience is impacted.

© 2018 SPLUNK INC.
Introducing Splunk SmartStore
Cut the Cord by Decoupling Compute and Storage
▶ Allowing compute and
storage tiers to be
independently scaled.
▶ Automatically evaluates
users’ data access
patterns to determine
which data needs to be
accessible for real-time
analytics and which data
should reside in lower
cost, long-term storage.

© 2018 SPLUNK INC.
Introducing Dynamic Data: Active Archive
Data Retention Options in Splunk Cloud
▶ Data Management
• Splunk provides complete lifecycle management of the
archive on your behalf and remains the custodian of your
data. Just like your Active Searchable data, Splunk
manages all aspects of archive availability, durability,
security and privacy requirements on your behalf.
▶ Data Restore
• Enables you to request a slice of your data to be restored
back into your Splunk Cloud instance. The entire workflow
is fully integrated into Splunk Web so your archived data is
available at your fingertips with predictable time between
retrieval to search.

Other Features!
Selection of Interesting New Releases!
▶ Dark Mode heightens visual contrast within Splunk dashboards.
▶ Workload Management enables users to prioritize the allocation of compute and
memory resources used by Splunk on searches and alerts to ensure users’ most
critical analytics are completed first.
▶ Guided Data Onboarding is a new graphical user interface helping customers
move data into Splunk Cloud or Splunk Enterprise and guiding them through the
best onboarding methodology based on their specific architecture.
▶ Logs to Metrics helps configure and convert log events to metrics, enabling
users to take advantage of breakthrough performance when monitoring and
alerting on metrics with the Splunk platform.
▶ Health Report gives Splunk administrators immediate visibility into the overall
health status of their Splunk environments.

Customer Challenges
“The expansion of
Splunk has increased
operational complexity,
as we manage it
manually and can’t
keep on top of project
change requests.”
– High-Street Retailer
“We require a full route-
to-live to maintain
system integrity and
can’t deploy changes
fast enough in our
current setup.”
– National Bank
“Multiple developers
within the same DEV
environment, causes
repeated configuration
conflicts and delays to
planned changes.”
– National Building Society

What Do We Want?
Enterprises Want to Respond Quickly, Safely & With Less Risk

▶ Identical environments & route-to-live
• Development, Pre-production, Production
▶ Eliminate fear driven development
• It’s ok to make mistakes!
▶ Minimize direct production changes
• Always go through route-to-live
• Transparent change control
▶ Modern means of disaster recovery
▶ Security driven

Let’s Share Secrets
No really, we are sharing!
▶ How to version sensitive information
• Encryption
▶ How to decrypt automatically
• Ansible Vault
▶ How to store Ansible Vault Password
• More encryption

Lessons We Learned
Not everything was easy…
▶ Multiple repositories
• What goes where?
• Many lines of history
▶ Identical code for different environments
• There are always exceptions (Eventgen, production API calls)
▶ Data for different environments
• Production data is sensitive
▶ Automated deployment of code
• When do you restart?
