Elastic Security opens public detection rules repo

At Elastic, we believe in the power of open source and understand the importance of community. By putting the community first, we ensure that we create the best possible product for our users. With Elastic Security, two of our core objectives are to stop threats at scale and arm every analyst. Today, we’re opening up a new GitHub repository, elastic/detection-rules, to work alongside the security community, stopping threats at a greater scale.

Canonical, Elastic, and Google team up to prevent data corruption in Linux

At Elastic we are constantly innovating and releasing new features. As we release new features we are also working to make sure that they are tested, solid, and reliable — and sometimes we do find bugs or other issues. While testing a new feature we discovered a Linux kernel bug affecting SSD disks on certain Linux kernels. In this blog article we cover the story around the investigation and how it involved a great collaboration with two close partners, Google Cloud and Canonical.

Preventing "copy-paste compromises" (ACSC 2020-008) with Elastic Security

The Australian Cyber Security Centre (ACSC) recently published an advisory outlining tactics, techniques and procedures (TTPs) used against multiple Australian businesses in a recent campaign by a state-based actor. The campaign — dubbed ‘copy-paste compromises’ because of its heavy use of open source proof of concept exploits — was first reported on the 18th of June 2020, receiving national attention in Australia.

How to use Kibana effectively. Today: Detect possible frauds in your data

Kibana is quite powerful and versatile for visualizing data in Elasticsearch. The Elastic Stack can be used for a variety of use cases. One is the detection of frauds e.g. in Banking transaction like within Softbank Payment Service or bonus point accounts like within Miles and More. Other areas are insurance or tax return data.

Why does Elastic Support keeping asking for diagnostic files?

If you’ve worked with Elastic Support, you may have been asked to run the Support Diagnostic tool and provide the output in your support case. This is a common practice, but a lot of you out there may not know why. While the short answer is "it depends", this blog is going to explain why we keep asking for diagnostic files (as well as what’s in them). Simply put, the Support Diagnostic helps Elastic Support understand the state of your cluster.

Journey of Elastic SIEM Getting Started to Investigating Threats: Part 2

Calling all security enthusiasts! Many of us are now facing similar challenges working from home. Introduced in 7.2, Elastic SIEM is a great way to provide security analytics and monitoring capabilities to small businesses and homes with limited time and resources. In this three part meetup series we will take you on a journey from zero to hero - getting started with the Elastic SIEM to beginner threat hunting.

Kubernetes observability tutorial: Log monitoring and analysis

Kubernetes has emerged the de facto container orchestration technology, and an integral technology in the cloud native movement. Cloud native brings speed, elasticity, and agility to software development, but also increases the complexity — with hundreds of microservices on thousands (or millions) of containers, running in ephemeral and disposable pods. Monitoring such a complex, distributed, transient system is challenging, and at the same time very critical.

Kubernetes observability tutorial: K8s cluster setup and demo app deployment

The easiest way to get the Elastic Stack up and running for this tutorial, is to spin up a 14-day free trial of our Elasticsearch Service on Elastic Cloud. A few clicks (no credit cards) and you’ll have your cluster up and running. Or if you prefer, download the Elastic Stack and install locally. All of the instructions in this tutorial can be easily amended to work with a standalone Elasticsearch cluster on your own hardware.

Machine learning in cybersecurity: Training supervised models to detect DGA activity

How annoying is it when you get a telemarketing call from a random phone number? Even if you block it, it won’t make a difference because the next one will be from a brand new number. Cyber attackers employ the same dirty tricks. Using domain generated algorithms (DGAs), malware creators change the source of their command and control infrastructure, evading detection and frustrating security analysts trying to block their activity.

Elastic Cloud roundup: API support, more regions, and new purchasing options

You can now benefit from even more features and functionality in Elastic Cloud. In case you missed it, we’ve added powerful tools to simplify and automate operations. We’ve added support for more regions. And we’ve even added new ways to pay for, and understand your bill for Elastic Cloud. With a cup of tea and five minutes, we’ll recap them for you.

Telecommunications observability with the Elastic Stack: Monitoring voice traffic data

Applying an observability strategy to core telecommunication data processing enables operators to answer questions that were not possible to answer before. As this approach has gained prominence, the Elastic Stack has become increasingly popular in the telecommunications space, with companies like Deutsche Telekom — their data transformation effort championed by Hans-Konrad Roth — adopting Elastic as their solution of choice for international traffic monitoring.

Threat Hunting with Elastic APM

Learn how APM lets you monitor the performance of applications deployed anywhere within your network. Now you can use APM data to hunt for threats and injection attacks, too. Elastic provides a common data platform so you can view HTTP data collected with your APM agents in the Elastic SIEM app. It’s seamless monitoring and protection to keep your systems up, running, and secure.

Calculating ingest lag and storing ingest time in Elasticsearch to improve observability

When viewing and analysing data with Elasticsearch, it is not uncommon to see visualizations and monitoring and alerting solutions that make use of timestamps that have been generated on remote/monitored systems. However, using remote-generated timestamps may be risky.

Searching Jira: Enhanced productivity with Elastic Workplace Search

Jira has long been a popular issue tracking tool for development teams, but its scope has broadened quite a bit over the years, and it has bloomed into a more well-rounded project management tool as well. It’s used widely by agile teams to plan, track, and release software, along with numerous other cloud (and traditional self-managed) productivity tools.

Real-time monitoring of Fastly metrics with the Elastic Stack and Haskell

The Stack Infra team at Elastic uses many services to provide downloads for projects like Elasticsearch and Kibana to our users. One of these services is Fastly, which helps us optimize delivery to regions around the world. Keeping an eye on the performance and behavior of our CDN is important to ensure we're operating at the level we expect.

Integrating Azure single sign-on with ECE in 1-2-3 at STRABAG

At STRABAG, we are using Elastic Cloud Enterprise (ECE) for two main use cases within our on-premises web applications. One to power different kinds of search and a second for operations where we ship more than 25,000 log entries per minute to Elastic from our load balancers. The ECE platform runs in an air-gapped environment, and we would still like to be able to use our corporate logins for the ECE platform.

What your Elastic App Search analytics are telling you

At Elastic, we love data. It’s the backbone of what we do: search. And that data takes many forms. A knowledge base article showing how to reset your cable box — data. Logs from your network — data. IP addresses accessing your secure network — data. A video tutorial on how adults can use TikTok — data. The list goes on. But behind each piece of data is a story. And a person. Or a customer.

Centralizing infrastructure metrics and planning for scale with the Elastic Stack

This post is the second in our series on system metrics where we cover: In the previous post, we went through some built-in tools and methods for identifying key metrics and values on your systems. In this post, we'll provide a tutorial on how to use Metricbeat to consolidate metrics, store and analyze them in the long term, and discuss some of the benefits of a centralized metric store.
