Secure Splunk Web in Five Minutes Using Let’s Encrypt
Configuring SSL for your public facing Splunk instance is time-consuming, expensive and essential in today’s digital environment. Whether you choose to go with a cloud provider or self-hosting; RTFM-ing how to generate the keys correctly and configuring how Splunk should use them can be quite confusing. Last year, a new certificate authority Let’s Encrypt was born in an effort to streamline the CA process and make SSL encryption more widely available to users (The service is FREE). In this short tutorial, we will cover how to make use of this new CA to secure your Splunk instance and stop using self-signed certs. Using SSL will help you to secure your Splunk instance against MITM attacks. Let’s Encrypt utilizes all of …
SIEM success patterns – How to get it right!
One of the things I love about machine data is that it can be used in so many ways. Interestingly enough over the years I have observed a common pattern in organizations that have been successful with SIEM. The implementation of a cyber defence center should serve to increase security maturity, strengthen cyber security skills and security intelligence, enabling organisations to successfully stop complex attacks (not just malware!) and better protect customer data and the overall business. Yet in the past I have been called in to meet with prospects regarding failed SIEM deployments and it doesn’t matter which traditional vendor it is there are always similar patterns.
What are the patterns of a failed SIEM deployment?
Splunk & the National Defense University: Educating the Security Warriors
Every six months, or once a semester if you are academically inclined, our Splunk Public Sector office in Tysons Corner, VA hosts students from the National Defense University (NDU) in Washington, DC to discuss emerging security trends, the evolving threat landscape and adaptive threat response initiatives that make all data crucial to security warriors.

Splunking a Microsoft Word document for metadata and content analysis
The Big Data ecosystem is nowadays often abbreviated with ‘V’s. The 3Vs of Big Data, or the 4Vs of Big Data, even the 5Vs of Big Data! However many ‘V’s are used, two are always dedicated to Volume and Variety.
Recent news provides particularly rich examples with one being the Panama Papers. As explained by Wikipedia:
The Panama Papers are a leaked set of 11.5 million confidential documents that provide detailed information about more than 214,000 offshore companies listed by the Panamanian corporate service provider Mossack Fonseca. The documents […] totaled 2.6 terabytes of data.
This leak illustrates the following pretty well:
- The need to process huge volume of data (2.6 TB of data in that particular case)
- The need to
Detecting and Responding to the Accidental Breach
Splunk recently commissioned analyst firm IDC to conduct research in EMEA into how capable organizations are at protecting and responding to hapless user activity. The research questioned 400 organizations across the region, producing some really valuable insights.
At a time when security breaches are inevitable, one of the primary threat vectors is what IDC calls the hapless user. It isn’t a case of the user being stupid – it’s because attacks are getting far better at tricking users into unintentionally clicking on the wrong link or opening attachments which they shouldn’t.
In the IDC report you can find out about the threats that companies are most worried about in EMEA, what security technologies they are using and what …
Spotting the Adversary… with Splunk
Howdy Ya’ll. Eventually there is a Rubicon to cross in every Security professional’s life. With a satisfied sigh he’ll take a step back from the keyboard, wipe Dorito dust covered hands on khakis, take a long slug of Mountain Dew, and gaze proudly at his Splunk instance and utter the words “I’ve added all the data sources I can. The network is being ‘monitored’”. Then the smile will falter as his cyber demons claw their way up to the surface. He’ll hear them scream out “but WHAT am I supposed to look for??” He (and you) are not alone. Ever since time immemorial (or at least when I first began “practicing” the dark arts of cyber security) I would hear the question of “but what …

PostFinance banks on Splunk to improve fraud detection
When I’m thinking about Switzerland, I often think of the Swiss Alps, great chocolate and the famous Swiss army knife. The flexibility of the Swiss army knife reminds me how Swiss bank PostFinance is using the Splunk platform in multiple ways.
