Validating Elastic Common Schema (ECS) fields using Elastic Security detection rules

The Elastic Common Schema (ECS) provides an open, consistent model for structuring your data in the Elastic Stack. By normalizing data to a single common model, you can uniformly examine your data using interactive search, visualizations, and automated analysis. Elastic provides hundreds of integrations that are ECS-compliant out of the box, but ECS also allows you to normalize custom data sources. Normalizing a custom source can be an iterative and sometimes time-intensive process.

Detection and Investigation Using Devo: HAFNIUM 0-day Exploits on Microsoft Exchange Service

On March 2, 2021, Microsoft announced it had detected the use of multiple 0-day exploits in limited and targeted attacks of on-premises versions of Microsoft Exchange Server. The Microsoft Threat Intelligence Center (MSTIC) attributes this campaign—with high confidence—to HAFNIUM, a group assessed to be state-sponsored and operating out of China, based on observed victimology, tactics and procedures.

Ransomware in 2021: What has changed? Detection and mitigation strategy

A ransomware attack is a bug that we can’t shake off. Or perhaps, it can even be called a shape-shifter that somehow finds a way into networks, no matter how many armed sentries you’ve deployed in and around your perimeter. The line between ransomware and a data breach is slowly fading. Threat actors prefer ransomware over other modes of attack because they work.

Deepfake cyberthreats - The next evolution

In 2019, we published an article about deepfakes and the technology behind them. At the time, the potential criminal applications of this technology were limited. Since then, research published in Crime Science has delved into the topic in-depth. The study identified several potential criminal applications for deepfakes. Among these categories, the following were deemed the highest risk: This list sparked the idea for this article.

Detecting and mitigating Apache Unomi's CVE-2020-13942 - Remote Code Execution (RCE)

CVE-2020-13942 is a critical vulnerability that affects the Apache open source application Unomi, and allows a remote attacker to execute arbitrary code. In the versions prior to 1.5.1, Apache Unomi allowed remote attackers to send malicious requests with MVEL and OGNL expressions that could contain arbitrary code, resulting in Remote Code Execution (RCE) with the privileges of the Unomi application.

Actions Not Words, Demos Not Slides

In network operations, it’s never the same day twice. Most network engineers love this aspect, but it has a dark side. The best plans often fall to the wayside—in an instant work stops and firefighting begins. In the last year, I’ve been part of a whole-day colo move, diagnosed an outage in the middle of the night, and resolved a slow performance issue. I know what the networking operations experience is like, and I know how much better it can be.

Combating Risk Negligence Using Cybersecurity Culture

With a growing number of threat sources and successful cybersecurity attacks, organizations find themselves in a tricky spot if they wish to survive cyberspace. Oftentimes, the adversaries are not the challenge; the obstacle is the organization’s culture. Just like culture influences who we are as a people, culture influences the cybersecurity tone of an organization. Every organization has its own unique fit and feel.

Best Active Directory Management Tools

IT teams rely on Active Directory (AD) to keep networks secure and maintain user accounts — but they often need to adhere to strict budget limitations when it comes to selecting software to help. That’s why we’ve put together this list of the top free Active Directory management tools. Our picks focus on AD tools that will help you complete routine AD management tasks much faster so your team has time to focus on other priorities.

Splunk for OT Security V2: SOAR and More

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.
