The principles of risk management concern the delivery of actionable information with respect to objectives of decision-makers. In a sense, risk management principles deal with removal of uncertainty.
To that end, consider for example the ISO31K standard that defines risk as the effect of uncertainty on objectives.
The "Principle" is always to optimize the potential benefit compared to the combined probability and consequences of any system failure. The specific items will vary depending on what "Risks" you need to manage. Financial risk management is quite different from Safety risk management, although there are overlaps in both concerns. Further, an individual or corporate level of "acceptable" risk will be different in every case although some consensus standards may be found.
