FAIR Terminology 101 – Risk, Threat Event Frequency, Vulnerability
The final term to examine is Vulnerability, the corresponding FAIR standard variable to Threat Event Frequency. Outside of FAIR, the term vulnerability from an InfoSec and IT perspective has a highly technical definition that permeates the industry. The FAIR standard presents a different way to consider software, hardware, or component deficiencies (Vulnerabilities) by assessing how they impact the susceptibility of the scoped asset to attempted attacks by a threat actor.

Translate this into FAIR-ese by recognizing that clause (i) is the probability that a threat event will occur or Threat Event Frequency; and that clause (ii) is Vulnerability. NIST now makes the astonishing claim that algorithm[s] or rule[s] for combining the determined likelihood values could be as diverse as taking the maximum of the two likelihoods, or the minimum, or one but not the other, or a weighted average. This guidance is offered in the spirit of affording organizations …

Factor analysis of information risk – Wikipedia
In FAIR, risk is defined as the probable frequency and probable magnitude of future loss. FAIR further decomposes risk by breaking down different factors that make up probable frequency and probable loss that can be measured in a quantifiable number. These factors include: Threat Event Frequency, Contact Frequency, Probability of Action, Vulnerability, Threat Capability, Difficult, Loss Event Frequency, Primary Loss Magnitude, Secondary Loss Event Frequency, Secondary Loss …

A Better Way to Understand Vulnerabilities with FAIR and RiskLens
Gathering Vulnerability Data for FAIR Analysis with RiskLens. FAIR analysts gather that probability estimate from the subject matter experts (SME’s) who best know the asset to be analyzed, the strength of its controls and the history of attempted and successful attacks. In FAIR analysis, the percentage is always expressed in a range to account for uncertainty. The RiskLens platform guides the interview process and data collection.

FAIR Risk Management Framework Checklist | RSI Security
Factor Analysis of Information Risk (FAIR) is designed to manage vulnerabilities and incidents within an organization, network, or system using a risk-based approach. The main strength of the FAIR risk framework is the use of numerical values, mathematics and quantification to get precise and accurate results and responses.

FAIR™️ risk methodology: quantifying and managing cyber risk
The FAIR™ taxonomy complements those qualitative methods by responding to their limitations on how to measure risk. Why the need for a new cyber risk analysis method? All risk analysis methods (ISO 27005, NIST CSF, COSO, OCTAVE, among others) that have existed on the market for the last thirty years are qualitative. They are based on IT expert opinions and experience” to rank risks with subjective scales. With such scales, the risk is stamped as low or high and …

(TEF) and Vulnerability (Vuln). In either case, it is generally expressed as a distribu-tion using annualized values, for example: Between 5 and 25 times per year, with the most likely frequency of 10 times per year. There are some scenarios where LEF is more appropriately expressed as a prob-ability than as a frequency. For example, we wouldn’t talk about the frequency of

The FAIR taxonomy in figure 3 is an example of a DAG. The metrics at the bottom of the graph are connected to intermediate nodes by arcs, representing probabilistic dependencies. These probabilistic dependencies are expressed between two variables in the conditional probabilistic table. In this way, probabilities propagate to the top of the graph. For instance, at the top level of this BBN …
