Hey there, We recently ran a series of webinars* on how different-sized cybersecurity teams modernized their security operations and embedded polling questions within the webinars to gather some feedback. A set of possible answers was selected based on the ENISA NIS Investments report. In this blog post I’d like to share the results of the polls and the conclusions we can draw from them.
Many of you might have seen our blogs about different techniques for identifying anomalies. Perhaps you even have a handful of analytics running in Splunk to identify anomalies in your data using statistical models, using probability density functions or even using clustering.
In January and February of 2021, the threat actor called Hafnium used a number of post-exploitation tools after gaining access to Exchange servers through a zero-day exploit. One of their persistence methods was creating new user accounts in the domain, giving them the ability to log back into the network using normal authentication rather than use a web shell or continue to re-exploit the vulnerability (which has since been patched).
By 2022, Gartner estimates that more than 3 out of 4 global organizations will be running containerized applications in production. With this comes a new set of monitoring challenges — ephemeral, short-lived infrastructure, complex service interdependencies and on-call developers who now need access to data for fast troubleshooting, just to name a few.
If you haven’t been living under a rock for the past few weeks, you've probably come across the recent Microsoft Exchange Server vulnerabilities and its associated exploits.Stop!!! The first thing you should do is to go and patch any Exchange servers you may be running, then you can come back and finish reading this blog. Microsoft's blog provides links to various tools to help in this regard.
Organizations are migrating an increasing amount of their infrastructure into the cloud. The cloud provides organizations with a number of benefits like greater scalability, improved reliability and faster time to value. However, these potential benefits can be offset if security is an afterthought.
Every security team should utilize security frameworks in their strategy and tactics to help reduce risk from common cybersecurity threats. Security frameworks guide organizations on how they should develop, build, and maintain their IT security policies and procedures while sharing best practices for meeting compliance requirements. Healthcare operations in particular are often presented with increasing regulatory scrutiny and obligations that must be met in order to be competitive.
Marie Kondo, a Japanese organizational consultant, helps people declutter their homes in order to live happier, better lives. She once said: Similarly, in security, operational teams are constantly bogged down by a “visible mess” that inhibits their ability to effectively secure their organization.
The way we ‘data’ is about to change, and Splunk’s Connect for Ethereum (aka EthLogger) is helping organizations to adapt. Splunk Connect for Ethereum enables organizations of all sizes to investigate, monitor, analyze and act upon their rapidly growing blockchain data sets across multiple chains.
Recently we announced in our blog post, "The OpenTelemetry Tracing Specification Reaches 1.0.0!," that OpenTelemetry tracing specifications reached v1.0.0 — offering long-term stability guarantees for the tracing portion of the OpenTelemetry clients. Today we’re excited to share that the first of the language-specific APIs and SDKs have reached v1.0.0 starting with OpenTelemetry Java and OpenTelemetry .NET.
I thought my last blog, Visual Link Analysis with Splunk: Part 3 - Tying Up Loose Ends, about fraud detection using link analysis would be the end of this topic for now. Surprise, this is part 4 of visual link analysis. Previously (for those who need a refresher) I wanted to use Splunk Cloud to show me all the links in my data in my really big data set. I wanted to see all the fraud rings that I didn’t know about. I was happy with my success in using link analysis for fraud detection.
Welcome to part 3 of the blog series where we go through how to forward container logs from Amazon ECS and Fargate to Splunk. In part 1, Splunking AWS ECS Part 1: Setting Up AWS And Splunk, we focused on understanding what ECS and Fargate are, along with how to get AWS and Splunk ready for log routing to Splunk’s Data-to-Everything Platform.
One of the biggest challenges that DevOps teams face is how to connect their efforts with the priorities of business leaders. In conversations we’ve had, developers and SREs discussed how they need to show business and engineering leaders that they are investing their time solving the right problems, and how solving these problems lead to overall better business outcomes.
In the last 90 days, the news of cyberattacks on critical infrastructure has been stunning. From the unprecedented breach represented by Sunburst to the more recent bone-chilling attack at the Oldsmar water facility, the urgency to secure critical infrastructure in transportation, utilities, energy, water, critical manufacturing, telecommunications, healthcare, government facilities and the defense sector has never been higher.
Digital transformation is accelerating at a staggering pace. Consider these statistics. In December 2019, Splunk partner Zoom had 10 million monthly active users. By the end of last year, that number was estimated to be closer to 300 million. It was part of an explosion of technological growth replicated across many industries and businesses in 2020. As Splunk CEO Doug Merritt said.
Splunk is a fantastic platform for ingesting, storing, searching and analysing data from logs, metrics and traces from a massive variety of sources. But does that mean we should ignore all of that data that doesn’t fall into these categories, like image and video data for example? Of course not!
I drive a 2005 Ford diesel pickup truck. Most of the time my truck runs great. But occasionally an orange light on the dashboard will flicker on to alert me that something is wrong. Unfortunately, there’s no information about what is wrong and why. My truck has a monitoring solution, but not an observability solution. In many cases, IT has the same problem as my truck.
When you have a team of security analysts that have a wide range of expertise, knowledge, and experience, it is natural to see the difference in the quality of work performed. One of the biggest challenges that security operation managers face when auditing the work performed is that some team members may execute different steps at different levels of rigor when investigating and remediating threats.
All the work presented in this blog post is open source and available as part of our Splunk Connect for Ethereum repository examples, including the instrumentation of Besu as a Docker container, the configuration of Splunk, and two applications showing how to monitor Besu syncing to the chain.
If you want just to see how to find HAFNIUM Exchange Zero-Day Activity, skip down to the “detections” sections. Otherwise, read on for a quick breakdown of what happened, how to detect it, and MITRE ATT&CK mappings.
Hey there, The European Union Agency for Cybersecurity (ENISA) has recently published its NIS Investment report - a survey conducted on European organisations identified as Operator of Essentials Services (OES) and Digital Service Providers (DSP).
For anyone who works in cybersecurity, getting a tough job done with severely limited resources is all in a day’s work. But when funding allocations suddenly shift after essential programs are already under development, it can be hard for even the most creative, resilient CIOs and CISOs to keep up.
Like many other industries, contact centers are increasingly relying on employees working from home. The WFH trend poses new challenges, but it also surfaces issues that were largely ignored before. This article explains how holistic monitoring with Splunk Contact Center Analytics and uberAgent help drive exceptional customer service.
With our ability to ingest GCP logs and metrics into Splunk and Splunk Infrastructure Monitoring, there’s never been a better time to start driving value out of your GCP data. We’ve already started to explore this with the great blog from Matt here: Getting to Know Google Cloud Audit Logs. Expanding on this, there’s now a pre-built set of dashboards available in a Splunkbase App: GCP Application Template for Splunk!
Some tasks are better off automated. Paying bills on time? Automated payments. Orchestrating a coordinated response to security alerts and triaging security events? There’s Splunk Phantom for that. Monotonous tasks, in our work and personal lives, should and can be automated in order to free up time and energy to focus on the things that matter.
