The Index of Cybersecurity

The Index is a sentiment-based measure of the risk to the corporate, industrial, and governmental information infrastructure from a spectrum of cybersecurity threats. It is sentiment-based in recognition of the rapid change in cybersecurity threats and postures, the state of cybersecurity metrics as a practical art, and the degree of uncertainty in any risk-centered field. In short, the Index of Cybersecurity aggregates the views of information security industry professionals as expressed through a monthly survey. Its form is an index for reasons that will become apparent.

The ICS value, which was originated by industry icon Dan Geer, has been maintained by TAG and NYU researchers since 2011 and is calculated on the basis of the sentiment responses received from participants. Higher ICS values suggest that the experts queried are pessimistic about the prospects for cybersecurity in a broad sense. Trends to date suggest an on-going increase in the pessimism of this practitioner group.
