Risk management is the discipline of identifying, monitoring and limiting risks. In some cases, the acceptable risk may be near zero. Risks can come from accidents, natural causes and disasters as well as deliberate attacks from an adversary. In businesses, risk management entails organised activity to manage uncertainty and threats and involves people following procedures and using tools in order to ensure conformance with risk-management policies. Risk management is also used in the public sector to identify and mitigate risk to critical infrastructure. Some traditional risk management programs are focused on risks stemming from physical or legal causes (e.g. natural disasters or fires, accidents, ergonomics, death and lawsuits). Financial risk management, on the other hand, focuses on risks that can be managed using traded financial instruments. In ideal risk management, a prioritisation process is followed whereby the risks with the greatest loss and the greatest probability of occurring are handled first, and risks with lower probability of occurrence and lower loss are handled in descending order.
