Improving Visibility in Security Operations with Search-Driven Lookups
Looking back on 2016, Splunk Enterprise Security added significant capabilities to its platform for security operations, including Adaptive Response, User & Entity Behavior Analytics (UEBA) integration and Glass Tables. Another capability that was added, but has received less attention is a new type of search that Splunk calls Search-Driven Lookups. Because there has not been as much attention put to this, I wanted to share a bit about this capability and how it can be used.
Search-Driven Lookups originated from a question that users of legacy SIEM providers often asked; how can Splunk dynamically create watchlists that can then be used in correlating new events against a watchlist? Enterprise Security has had the ability to correlate against a …

Creating McAfee ePO Alert and ARF Actions with Add-On Builder
One of the best things about Splunk is the passionate user community. As a group, the community writes amazing Splunk searches, crafts beautiful dashboards, answers thousands of questions, and shares apps and add-ons with the world.
Building high quality add-ons is perhaps one of the more daunting ways to contribute. Since the recently-updated Splunk Add-On Builder 2.0 was released, however, it’s never been easier to build, test, validate and package add-ons for sharing on SplunkBase.
Technical Add-Ons, aka TAs, are specialized Splunk apps that make it easy for Splunk to ingest data, extract and calculate field values, and normalize field names against the Common Information Model (CIM). Since the release of version 6.3, Splunk Enterprise also supports TAs for …

Developing Correlation Searches Using Guided Search
Guided Search was released in Splunk Enterprise Security 3.1, nearly two years ago, but is often an overlooked feature. In reality, it is an excellent tool for streamlining the development of correlation searches. The goal of this blog is to provide a better understanding of how this capability can be used to create correlation searches above and beyond what Enterprise Security has to meet your unique security requirements.
So what is Guided Search?
It’s a “wizard”-like process to gather the key attributes that make up a correlation search. Essentially, there are five elements to Guided Search:
- Identify the data set to search
- Apply a time boundary
- Filter the data set (optional)
- Apply statistics (optional)
- Establish thresholds (optional)
Along the way, …
Rapid Response and Discovery (RRD) – Stop chasing alerts and start raising the cost for the adversary
In this discussion we will learn why RRD is an absolute necessity. We will establish the core capabilities required for RRD. Then we will walk through how ES 4.0 delivers on the capabilities for RRD. Finally, we’ll show how we can extend RRD and add our own flavor using the existing capability in Splunk Enterprise and ES 4.0.
State of Affairs for Cyber Operations
Cyber operations teams receive far more alerts than they can handle. Once they receive an alert, analysts spend a lot of time manually connecting the dots. As a result, alerts drive the cyber posture for an organization. And cyber operations teams are stuck in a never-ending loop of chasing individual incidents. As a result, operations teams …
Improve Your Ability to Detect, Scope and Respond to Advanced Attacks with Splunk ES 4.0
For as long as I’ve been in security, vendors have talked about the “emerging threat landscape” and warned organizations not to be passive or to settle for “good enough” security. Never in my career have those words been truer than they are today. In fact, today’s threats are so different than those of the past that security professionals are now required to approach investigations in a radically different way.
Today’s threats are dynamic in nature, often comprising a series of activities over a long period of time. This makes them difficult to investigate, requiring the analyst to be equally as dynamic in his or her activities to fully scope the infection. It’s also rare these days that a threat only …
Duqu 2.0 – The cyber war continues on a new level
recently i blogged already how important it is to apply today’s threat intelligence information to historical data. I gave the example the Duqu malware, which contained a self destroy capability to remain hidden. It seems the hiding strategy has evolved to a new level…
What has happen?
Today (10th June) Kaspersky Labs announced that they have been attacked by a new version of Duqu. At the time of writing it has been imaginatively named Duqu 2.0. It’s a very sophisticated piece of cyber-espionage malware and speculation is that it was a nation-state behind the attack with an estimated cost to creation the malware of around $50 million. The entire malware platform relies heavily on zero-day vulnerabilities to jump into systems and from …
