Hello, security enthusiasts! This is part seven (can you believe it?) of the Elastic SIEM for home and small business blog series. If you haven’t read the first six blogs in the series, you may want to before going any further. In the prerequisite blogs we created our Elasticsearch Service deployment (part 1), secured access to our cluster by restricting privileges for users and Beats (part 2), then we created an ingest pipeline for GeoIP data and reviewed our Beats configurations (part 3).

Given the complexity of large enterprise environments, coupled with the diversity of the vendor landscape, there is no single, agreed-upon “best” way to buy security. The battles continue between CAPEX or OPEX, net-30 or net-90, annual or multi-year, perpetual or subscription. One thing we do know, however, is that all too often the consumer pays for something he or she does not use.

This blog post is one in an occasional series about how we at Elastic embrace our own technology. The Elastic InfoSec team is responsible for securing Elastic and responding to threats. We use our products everywhere we can — and for more than just logs. By harnessing the power and breadth of capabilities of the Elastic Stack, we are working on tracking risk and performance metrics, threat intelligence, our control framework, and control conformance information within Elastic.

This is the third and final post of a three-part series on understanding kernel extension frameworks for Mac systems. In part 1, we reviewed the existing kernel extension frameworks and the information that these frameworks can provide. In part 2 we covered techniques that could be used in kernel to gather even more details on system events. In this post, we will go into the new EndpointSecurity and SystemExtensions frameworks.

For several months, the Intelligence & Analytics team at Elastic Security has tracked an ongoing adversary campaign appearing to target Ukranian government officials. Based on our monitoring, we believe Gamaredon Group, a suspected Russia-based threat group, is behind this campaign. Our observations suggest a significant overlap between tactics, techniques, and procedures (TTPs) included within this campaign and public reporting.

Hey, there. This is part six of the Elastic SIEM for home and small business blog series. If you haven’t read the first, second, and third blogs, you may want to before going any further. In the Getting started blog, we created our Elasticsearch Service deployment and started collecting data from one of our computers using Winlogbeat. In the Securing cluster access blog, we secured access to our cluster by restricting privileges for users and Beats.

Hey, there. This is part five of the Elastic SIEM for home and small business blog series. If you haven’t read the first, second, and third blogs, you may want to before going any further. In the Getting started blog, we created our Elasticsearch Service deployment and started collecting data from one of our computers using Winlogbeat. In the Securing cluster access blog, we secured access to our cluster by restricting privileges for users and Beats.

In the previous post, we covered some of the frameworks accessible by kernel extensions that provide information about file system, process, and network events. These frameworks included the Mandatory Access Control Framework, the KAuth framework, and the IP/socket filter frameworks. In this post, we will go into the various tips and tricks that can be used in order to obtain even more information regarding system events.

This year at BSidesDFW, my local security conference, I highlighted a continuing trend of adversaries using open source offensive tools. The talk reviewed one of these post-exploitation frameworks named Koadic and walked through different ways defenders can build behavioral detections through the use of Event Query Language (EQL).

When it comes to having visibility and detecting threats on macOS, one of the best sources of information for file system events, process events, and network events is the kernel. MacOS kernel extensions provide the ability to receive data about these events in real time with great detail. This is good for providing quick visibility into detecting anomalies and identifying possible threats.
