Practical CPU time performance tuning for security software: Part 2

In a previous blog, we discussed how to monitor, troubleshoot, and fix high %CPU issues. We also revealed a system API that could have an unexpected impact on CPU consumption. In this episode, we’ll discuss another time-related performance aspect that is unique to security software: application startup time. You don’t need to be a developer to benefit from this article.

Elastic Security prevents 100% of REvil ransomware samples

Users of Elastic Security are protected through numerous layers of protections against the REvil ransomware that affected Kaseya VSA and its customers. Elastic Security’s layered protections prevented 100% of the REvil ransomware samples tested before damage and loss could occur to the business. We believe that detections and preventions must be layered, as no single protection works 100% of the time.

Elastic Security Recognized in the 2021 Gartner Magic Quadrant for SIEM

We’re excited to share that Elastic Security has been recognized in the 2021 Gartner Magic Quadrant for Security Information and Event Management (SIEM). Elastic Security is the latest Elastic solution to be recognized in a 2021 Gartner Magic Quadrant report, following the 2021 Magic Quadrant for Insight Engines and 2021 Magic Quadrant for Application Performance Monitoring.

Ingesting threat data with the Threat Intel Filebeat module

The ability for security teams to integrate threat data into their operations substantially helps their organization identify potentially malicious endpoint and network events using indicators identified by other threat research teams. In this blog, we’ll cover how to ingest threat data with the Threat Intel Filebeat module. In future blog posts, we'll cover enriching threat data with the Threat ECS fieldset and operationalizing threat data with Elastic Security.

How the Elastic InfoSec team uses Elastic Security

At Elastic, we internally use, test, and provide feedback on all of our products. For example, the Information Security team is helping the Product team build a stronger solution for our customers. The InfoSec team is an extremely valuable resource who acts not only as an extension of Quality Assurance/Testing, but also as a data custodian.

Practical CPU time performance tuning for security software: Part 1

Software performance issues come in all shapes and sizes. Therefore, performance tuning includes many aspects and subareas, and has to adopt a broad range of methodologies and techniques. Despite all this, time is one of the most critical measurements of software performance. In this multi-part series, I’ll focus on a few of the time-related aspects of software performance — particularly for security software.

Why UC Davis chose Elastic to enhance its Security Operations Center

The University of California at Davis is an agriculturally focused university of more than 30,000 students. Founded in 1905, the university performs federally funded research for the U.S. Department of Defense, U.S. Department of Agriculture, and other agencies. It’s also home to an electric power substation, police and fire departments, and even an airport. All of this combined is a digital security challenge for Jeff Rowe, the university’s cybersecurity architect.

What you need to know about Process Ghosting, a new executable image tampering attack

Security teams defending Windows environments often rely on anti-malware products as a first line of defense against malicious executables. Microsoft provides security vendors with the ability to register callbacks that will be invoked upon the creation of processes on the system. Driver developers can call APIs such as PsSetCreateProcessNotifyRoutineEx to receive such events.

Adversary emulation with Prelude Operator and Elastic Security

It’s no secret that organisations are up against skilled, relentless and determined adversaries. Security operations teams need to continuously test their detection capabilities by carrying out adversary emulation plans that are made up of varying tactics, techniques and procedures (TTPs) and track key metrics of their coverage in order to close any existing gaps. There are many tools available for running adversary emulation plans and performing purple team exercises.

How South Dakota Bureau of Information and Telecommunications deploys Elastic to secure endpoints

The South Dakota Bureau of Information and Telecommunications (BIT) provides quality customer services and partnerships to ensure South Dakota’s IT organization is responsive, reliable, and well-aligned to support the state government’s business needs. The BIT believes that “People should be online, not waiting in line.” The bureau’s goals for the state's 885,000 residents include.
