The conversation also touches on the ethical dilemmas CISOs face when interacting with venture capital, highlighting pers

The notion of "Risk Acceptance" has always challenged me. For the uninitiated, Risk Acceptance is a concept often discussed in cybersecurity leadership when it comes to accountability for cyber debt. The idea is that cybersecurity leaders and other professionals identify risks and recommend mitigating actions that would reduce that risk, but recognize that it is always up to business leadership to weigh the costs and benefits of change and make a final decision. Risk Acceptance has always come u

We've all run to the same side of the boat on supply chain security when it comes to cyber. Rather than chasing the Sisyphean (and antithetical to modern product-development philosophy) task of ensuring our suppliers deliver perfectly secure software, we should be expected to architect and deploy our dependencies with the assumption they will be compromised at some point, minimizing the amount of impact that could have and ensuring we could detect such an issue timely. To expound on it, I'll sa

Years ago I found myself in one of those awkward elevator pairings where you are unexpectedly face to face with your CEO. It's a particularly awkward spot when you are a CISO, as beyond the usual desperation to sound brilliant that most execs feel in that spot, the CEO these days also feels pressure to demonstrate "tone at the top", "executive buy-in", and "stakeholder oversight" when given the chance. In that particular vignette I doubled down on the awkwardness, as his quick cordial cyber com

As part of my advisory work, I often help companies find and/or interview security leaders. While I'm a huge fan of screening quizzes, I realized that I should go a step further and help firms understand what I'm trying to detect or avoid during the interview process. In the process of discussing this with some peers, the Bad CISO Archetypes list was born. Look out for these when you are hiring - but more importantly steer your career to avoid becoming one! Chicken Little You don’t want someo

I used to have a TVM team. Threat & Vulnerability Management. The individuals in there had the word "Vulnerability" in their titles. It's how a lot of shops roll. TVM seemed to become a default piece of the "build a cyber shop playbook". And if you survey big CISO organizations today, you'll still find a lot of TVM departments. I'm not sure how this came to be, but I can't think any of us ever organically decided that we needed an individual - no less a team - specifically tasked with managing

I've been using the term "West Coast CISO" a lot lately. While it feels like CISOs used to be either network/infrastructure CISOs or risk manager CISOs, now the split is having to make room for the CISO heavily focused on code security. The image is one of a CISO born in the cloud, focused on delivering (security) bug-free code, and thus focusing architecturally on CI/CD, change control, and automation, to oversimplify. This emphasis on code is contrasted with network controls and discussion of

There is a misconception out there that security departments should be ingesting feeds of Indicators of Compromise (IOCs) and loading them into firewalls, endpoint software, and proxy configurations as soon as possible. This perception is amplified by product marketing focused on the task, and it's easy to get caught up in the idea that this is our mission. By the time an IOC has been published in an intelligence report, there is a high likelihood it has been neutralized. Imagine a command & co

Patching became a household term during the Equifax security breach and Congressional hearings. While IT maintenance and hygiene have their place in running a secure environment, over-emphasis can distract limited resources from more important tasks or trigger operational risks. Patches are only relevant when a security vulnerability is known and addressed by a vendor. So whether it is a 0-day vulnerability discovery without a patch yet available or just the unavoidable window between the time

Multifactor authentication (MFA / 2FA) is arguably the most powerful security control deployed over the past 20 years. But it dawned on me that it isn't multi that's really getting it done. It's the fact that one of those factors has been a one-time-password (OTP or 1TP) in a token or app that changes every 60 seconds. The unwritten math about MFA is that a single factor is difficult to compromise, and thus two of them = difficult^2. But in reality our static credentials have become easy thanks
