The Hoot - Episode 24 - How Daniel Card uses Humio at CV19 to protect healthcare systems

May 14th, 2020

Daniel Card, founder of Xservus and Pwndefend.com joins John to talk about how he uses Humio in Cyber Volunteers 19 (CV19), an all-volunteer task force he co-founded to protect the cybersecurity of data used by healthcare workers in the face of the COVID-19 outbreak. CV19 is sharing vulnerability information with intelligence agencies who in turn share it with compromised health organizations so they can take steps to protect themselves.

In the podcast, before we start talking about the cloak-and-dagger work, Daniel starts by telling about how he got his start in tech as a consultant. From there he worked his way up to managing IT infrastructure and automation, and eventually was responsible for 25,000 machines before leaving and starting his own security consulting company, Xservus.

As we turn toward a security focus, he warns of the rampant vulnerabilities he sees existing in internet-facing security from mismanagement of technology. He provides a straightforward means of addressing those gaps in security, pointing out that each use case is different and must be addressed stepwise to systematically identify assets, threats to those assets, and ways to add protection. He notes that most common compromises in a system come from simple credentials leak or an unsecured gateway.

Daniel next talks about the start of the CV19 volunteer program and the real dangers he saw where cyber vulnerability intersected with health care.

He explains how the CV19 team is using Humio to create a top-level view of countrywide data sets. From there, they can measure levels of protection and quantify their success. Also it provides a means of focusing on specific logs.

“We took Humio and make it into a decision-making tool. That means we can look and slice and dice to the point at which we have something that gives us a broad view that we can zoom into.”

Daniel explains CV19’s work as a passive monitoring operation that passes data along rather than engaging with threats actively. Along the way, he attempts to clear up some misconceptions about cybersecurity. For users looking to protect themselves, he points to a handful of ways users can harden their systems and prevent the most opportunistic types of attacks.
