The Risk Acceptance Myth

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

Encryption is Overrated

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

Network Egress and Ingress Fundamentals

There is a lot of confusion about network ingress and egress. This isn't limited to junior staff; I've witnessed this many times among software engineers and technology leaders alike. Often only network and firewall engineers really comprehend the topic fully, though this should not be the case. A network connection must begin with an "initiator". This is usually thought of as a "client" in a traditional "client server" model. The client is defined not by their intention, purpose, or operating

How much AppSec is too much?

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

It's not the 2FA.. it's the 1TP!!!

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

Quick trick to assess your vulnerability to SIM swapping

I listened to an NPR story on SMS SIM swapping on my drive in this morning. This is a pretty well-documented threat vector whereby adversaries port your phone number over to their device at a key moment in an authentication hack so they can intercept a one-time verification code and impersonate you. The way it usually plays out, the intercepted code plays a part in "recovering" a "lost" password for your email account, which they then use to "recover" more passwords for more important accounts,
