XDR explained in 300 words

XDR is the rising star of new acronyms, but you might have to read a 1,000+ word long article to understand its value. Let’s try to do it briefly in about 300 words. X means to expand DR’s – Detection and Response – systems – to cover your entire attack surface, not just a portion of […]

Open XDR vs. SIEM

Matching Resources and Business Risk with the Right Solution Gaining visibility and responding to attacks across the entire enterprise infrastructure (endpoints, servers, applications, SaaS, cloud, users, etc.) is a very tall order in today’s cybersecurity environment. Enterprises are forced to create complex security stacks consisting of SIEM, UEBA, SOAR, EDR, NDR, TIP and other tools in order to meet this […]

Does XDR Need a New Kill Chain?

The time has come for cyber security technology to keep up with the adversaries.  Now that we have seen so many successful multi-stage attacks, we need to reassess the way we correlate the signals we are seeing from all the security tools in our environments.  Correlation is helpful but it doesn’t always paint the complete […]

Is Extended Detection and Response (XDR) the Ultimate Foundation of Cybersecurity Infrastructure?

Security information and event management (SIEMs) collect data from security logs and in doing so are supposed to identify blind spots, reduce noise and alert fatigue, and simplify detection and response to complex cyberattacks. However, SIEMs have not lived up to these promises. Now, the new idea is extended detection and response. What are its advantages, […]

Alerts, Events, Incidents – Where Should Your Security Team Focus?

By Brian Stoner, Vice President, Service Providers at Stellar Cyber As the cybersecurity threat landscape is evolving so is the way we need to look at those threats.  The drumbeat of new breaches is continuous. If you read the news, you would be led to believe that there is only one major tactic the attackers leverage in […]

The Pipeline Attack – Is Log Analysis Enough for Cybersecurity?

Many MSSP’s use SIEMs and other log management/aggregation/analysis solutions for cybersecurity visibility, but is log analysis enough? We’re hearing more and more about holistic security solutions like XDR platforms that claim to cover the entire attack surface, especially because the latest pipeline attack reinforced the compound nature of today’s sophisticated multi-stage cyberattacks. The attackers admitted they did not expect their attack […]

The Case for Open XDR – X Means Everything

The current model for cybersecurity is broken. It consists of acquiring and deploying a lot of stand-alone tools, each with its own console, to analyze logs or traffic and detect anomalies that could be threats. In this model, it’s up to each security analyst to communicate with other analysts to determine whether each tool’s individual detection (each […]

Cyberthreats Go Sideways

The cyber threats are going sideways. Here I’m not talking about Sideways, the 2004 movie starring Paul Giamatti and Thomas Hayden Church that made Pinot Noir famous while the pair traveled through Santa Barbara County wine country in seven days. Rather, I’m talking about cyberattacks that work through lateral movement through your network infrastructure. No one wants to get famous because […]

XDR Delivers Significant Performance Improvement over SIEM

In every SOC environment, there are two key metrics that demonstrate efficiency and effectiveness: Mean Time to Detection (MTTD) and Mean Time to Remediation (MTTR).  The risk and exposure from any cyber threat can be reduced significantly by improving these metrics.  Stellar Cyber recently completed a study with its MSP and MSSP partners, to determine how much our Open […]

Was SUNBURST really a Zero-day attack?

Most companies affected by the SolarWinds attack learned about it from the Department of Homeland Security. Wouldn’t it have been better for them to have learned from their MSP/MSSP before DHS came calling? With Stellar Cyber, you would have known right away. The reason this breach was so successful was that the attackers leveraged a trusted source – the software […]
