Vulnerability Disclosure and Responsible Exposure

Continuing our miniseries into Risk, Measured: we go back to statistics class and discuss some of the characteristics of good metrics to help people understand what you should be looking for when you want to meaningfully quantify cybersecurity phenomena, program performance, or anything really.

Risk, Measured: 7 Characteristics of Good Metrics

Sometimes a number is just a number. Context - the information and environment around the number - is what really matters. We discuss how this concept holds especially true in vulnerability management and risk scoring.

Why Vulnerability Scores Can’t Be Looked At In A Vacuum

We discuss the general lack of defensive perspectives in cybersecurity media and culture, how that impacts perceptions and decision making, and what we can do about it.

We look at the phenomena of exploit code moving from traditional and cybersecurity-centric databases like Exploit-DB and Metasploit and instead being published on Github. Is Github becoming a de facto database for exploit code?

Github as a Source for Exploits?

Kenna Security recently celebrated its 10-year anniversary on Dec. 10th, 2020; so we decided to do what we do best and take a data-based (and rare) review of the top vulnerabilities from the past decade, year-by-year.

We discuss the sixth and latest report in our ongoing dive into the Prioritization to Prediction research series by Kenna Security and The Cyentia Institute. Prioritization to Prediction volume 6: The Attacker-Defender Divide looks at exploitation events from 2019 to analyze the momentum shifts between cybersecurity hackers and the teams defending organizations from attack.

We discuss the fourth report in our multi-part dive into the Prioritization to Prediction research series by Kenna Security and The Cyentia Institute. Prioritization to Prediction volume 4: Measuring What Matters In Remediation.

Measuring What Matters w/ Cyentia Institute

We discuss the evolution of cybersecurity metrics and reporting to Boards of Directors.

Reporting Risk To The Board

We discuss the third report in our multi-part dive into the Prioritization to Prediction research series by Kenna Security and The Cyentia Institute. Prioritization to Prediction volume 3: Winning the Remediation Race looks at (1) how quickly and (2) how many vulnerabilities a given organization can handle. Answering two key questions: Can organizations remediate all of the new vulnerabilities in their environments? If not, can organizations remediate all of the new High-Risk vulnerabilities in their environments?

Winning The Remediation Race w/ Cyentia Institute

Today on Security Science, we have a special around the virtual table with some of the biggest names in cybersecurity discussing a wide range of topics like securing remote workers, whether companies are really moving to the cloud, and the impact of the 2020 presidential election. 

Around the Virtual Table with Chris, Jeremiah & Ed

We discuss the Exploit Prediction Scoring System (EPSS), the first open, data-driven framework for assessing vulnerability threat: that is, the probability that a vulnerability will be exploited in the wild within the first twelve months after public disclosure.

The Exploit Prediction Scoring System (EPSS)

We discuss the second report in our multi-part dive into the Prioritization to Prediction research series by Kenna Security and The Cyentia Institute. Prioritization to Prediction, Volume 2: Getting Real About Remediation picks up on the overall vulnerability landscape analysis from Volume 1 and dives deep into the vulnerability landscape from within actual enterprise networks (a little over 500 of them to be exact).

Getting Real About Remediation w/ Cyentia Institute

How does the spread, detection, and response to viruses like COVID-19 compare with cybersecurity practices today? In the second episode of our Risk, Measured series we talk to special guest, Northeastern University Assistant Professor, Sam Scarpino about how Epidemiology relates to cybersecurity.

Risk, Measured: Epidemiology for Cybersecurity

We chat about the state of everyone’s favorite buzz technology: Threat Intelligence with our favorite internet fingerprinter, Kenna’s head of research, Jcran. Joining us is a special guest, longtime pentester, infamous internet listener, and founder of GreyNoise Intelligence, Andrew Morris.

Both the bane and salvation of security teams, and the start of a month-long fix cycle for IT teams, Microsoft's Patch Tuesday is a consistent reminder that nothing keeps us more secure than good old fashioned cyber-hygiene. Kenna Security's Head of Research, Jcran walks us through his Patch Tuesday ritual and gives us some tools, tips, and tricks along the way.

2020's global Covid-19 pandemic has yet again thrust the concept of Zero Trust architectures into the security mainstream. Researcher, Builder, Hacker, Traveler, and Kenna's head of Security and Compliance, Jerry Gamblin discusses Zero Trust and the realities of the work required to truly adopt the architecture, probably bursting a few bubbles along the way.

Building Zero Trust is Hard

In the very first episode of Security Science the Father of Risk-Based Vulnerability Management, Ed Bellis walks us through the history of Vulnerability Management. From the dark times before the CVE list and open-source scanners to the capabilities of today's best performing vulnerability management programs.

Cybersecurity shouldn’t be a black box. Security Science aims to demystify cybersecurity with education combined with a dose of entertainment. We will tap a mix of experts to tackle the gamut of security topics - from the (mis)use of AI to deep analysis of specific vulnerabilities - grounding out each episode with measurable outcomes or joking around when there is a lack thereof. New episodes every Wednesday.
