Is Cyber Risk Measurement Just "Guessing"?

[fa icon="calendar'] Sep 12, 2017 12:36:29 PM / by Jack Jones posted in FAIR, Risk Management

[fa icon="comment"] 0 Comments

I regularly read blog posts or encounter people in our profession who dismiss quantitative cyber risk measurement as “guessing”, or “nothing more than feelings” (cue the Morris Albert song).  Since this is such a common concern, I thought it would be worthwhile to examine this issue of what's subjective, what's objective and what falls between.

A FAIR View of Risk Appetite - Part 4 (finally!)

Some of you may recall a series of posts I wrote on this topic last year. In the third post of that series I said I’d write another post that lays the foundation for dealing with risk appetite more effectively.  Well, here we are a year later and I’m finally going to fulfill that promise.  Hopefully, you’ll find the wait worthwhile.

Measuring Reputation Damage in Cyber Risk Analysis - Part 1

In a recent survey, information security professionals identified reputational damage as the most costly form of loss from cyber events.  But is it really?  In this first post in a series I’ll lay some groundwork that should help us evaluate the potential impact of cyber event-related loss of reputation.

Cyber Economics: Smarter (vs. More Expensive) Cybersecurity

Recently, the Wall Street Journal (WSJ.com) published two charts from Juniper Research that paint a disheartening picture of the state of cybersecurity.  One chart shows a projection of cybersecurity spending increasing (more or less linearly) over the coming five years, while the other chart projects a more exponential-looking growth in cybersecurity losses over that same timespan.

Measuring Cyber Risk Requires Two Models, Not One

There are a lot of reasons why some people believe measuring cyber risk isn’t possible — from misperceptions about data shortage, to the fallacy about intelligent adversaries, to the inconsistencies that commonly occur when two different people get two different answers when measuring the same risk.

How to Deal with "Data Challenged" Risk Analyses

[fa icon="calendar'] May 2, 2017 10:36:38 AM / by Jack Jones posted in FAIR

[fa icon="comment"] 3 Comments

In the first two posts of this series, I discussed questions regarding how to make estimates when data is sparse or missing altogether, and how to account for the fact that historical data may not perfectly reflect the future.  In this post, I’ll walk through an example risk analysis that is challenged in both of those respects.

Using Historical Data

In my previous post (No Data? No Problem) I discussed the question, “How do you make estimates when you have no data?”  This post focuses on a related question – whether historical data can be relied upon to reflect the future.

No Data? No Problem

One of the most common questions I hear is, “ What if there’s no historical data to base an estimate on?”  A close cousin to this question is the statement, “ Historical data isn’t necessarily a good representation of the future, so you can’t rely on it for your estimates.”  Both of these are reasonable concerns that deserve good answers.

What Belongs in a Risk Register?

A member of the FAIR Institute LinkedIn forum asked an important question the other day: 

“I was wondering if there are any guidelines, rules-of-thumb, etc. on how to decide when something should end up in a risk register or should be handled differently.
