Risk
Risk is the potential of gaining or losing something of value. Values (such as physical health, social status, emotional well-being or financial wealth) can be gained or lost when taking risk resulting from a given action or inaction, foreseen or unforeseen. Risk can also be defined as the intentional interaction with uncertainty. Uncertainty is a potential, unpredictable, and uncontrollable outcome; risk is a consequence of action taken in spite of uncertainty.
Risk perception is the subjective judgment people make about the severity and probability of a risk, and may vary person to person. Any human endeavor carries some risk, but some are much riskier than others.

RISKS Digest
The RISKS Digest or Forum On Risks to the Public in Computers and Related Systems is an online periodical published since 1985 by the Committee on Computers and Public Policy of the Association for Computing Machinery. The editor is Peter G. Neumann.
It is a moderated forum concerned with the security and safety of computers, software, and technological systems. Security, and risk, here are taken broadly; RISKS is concerned not merely with so-called security holes in software, but with unintended consequences and hazards stemming from the design (or lack thereof) of automated systems. Other recurring subjects include cryptography and the effects of technically ill-considered public policies. RISKS also publishes announcements and Calls for Papers from various technical conferences, and technical book reviews (usually by Rob Slade, though occasionally by others).
Although RISKS is a forum of a computer science association, most contributions are readable and informative to anyone with an interest in the subject. It is heavily read by system administrators, and computer security managers, as well as computer scientists and engineers.
