Splunk Add-on > Where’s That Command – Converting a Field’s Hexadecimal Value to Binary

When looking through Splunk’s Search Reference Manual, there are a ton of search commands with their syntax, descriptions, and examples.  After all, if Splunk is the platform for machine data, there needs to be an extensive list of commands, functions, and references that guide Splunkers through the Search Processing Language (SPL).  But one would think that we had everything covered, right?  Well, almost….

I have a couple of great customers from the Houston, Texas area to thank for this.  Gabe and Andrew (you know who you are) are not only strong Splunkers, but frequent the Splunk Houston User Group (SHUG) meetings and are always looking for ways to expand their use of Splunk as well …

Hello everyone!

I am Michael Uschmann, one of the members of the SplunkTrust.

Lately I was annoyed by the fact that I had to enter my login on my Splunk DEV VM after a meeting or break. So, I thought ‘Why not setup SSO on this Splunk instance so I don’t have to enter my password again?’ But there was this …

Introducing Splunk Security Use-Cases

Screen Shot 2016-02-03 at 9.13.33 AMOne of the top challenges faced by Splunk customers and Security practitioners is to keep up with the increase in new cyber attacks while investigating and remediating existing threats.

To mitigate this persistent problem, Splunk recently introduced new security use case descriptions. These use case descriptions are ready-to-use examples of how to use Splunk security solutions to quickly identify the scope of attacks, determine mitigation options and take remedial activity.

These use case descriptions solve ambiguous as well as known security problems using actionable examples. They …

Top Technical Questions on Splunk UBA

With the acquisition of Caspida (now Splunk UBA) in July of 2015, we have been talking to many customers regarding user and entity behavioral analytics. Our customers have been asking questions about how this type of threat detection product works, and in this blog, I’m going to discuss some of the most common questions, along with answers and/or explanations from a security researcher and practitioner’s viewpoint.

Splunk UBA uses an unsupervised machine-learning based approach to determine whether events generated from multiple data sources are anomalies and/or threats. This is a turnkey approach that does not require customers to train the models, and does not require administrators to develop signatures in …

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 …

Splunk at the Wall for DEF CON 23 – Part II

­­­­Splunk at the Wall for DEF CON 23 – Part II

Hello again. Since the initial post, we’ve released the app developed for the Wall of Sheep. I’m going to go over the functionality here.

To review, the WoS app is meant to be a proof of concept that shows the type of data that traverses the wire, in the clear. Some of the data is innocuous, but we try to highlight the data that could be used by adversaries targeting your data. In fact, you may not even know that you have software using insecure protocols, so it pays to dig in and find out.

Before we go through the various dashboards, I want to comment on …

Security Forecast for 2016

1215-f-predictions-cover_8805752016 is off to a cracking start with security news – tech announcements, nation state threats, new challenges and new opportunities. Lots of people have made predictions on what we can expect in the next 12 months?

haiyansong_892575Our Vice President of Security Markets, Haiyan Song, takes a different approach for these predictions in SC Magazine. She focuses on action, results, and preparedness. Haiyan notes that as we enter the new year, both government and industry will need to demonstrate how they learned from last year’s cyber mistakes. According to Haiyan, now is the time for the private and public sectors to reexamine cybersecurity strategy, invest in the right technology, bring focus back to people and put new ideas into action. Haiyan encourages the community to evolve our way out of 2015 – the year of the breach – and begin to pivot towards …
