Risk mitigation refers to the processes and strategies that organizations use to reduce the likelihood or impact of potential risks. Improving security controls is a classic example of risk mitigation. By implementing or enhancing security controls, organizations can reduce the risk of security incidents or breaches, such as data theft or unauthorized access. For example, implementing strong passwords, regularly updating software and systems, and training employees on security best practices are all ways to improve security controls and mitigate risk. Other examples of risk mitigation include implementing disaster recovery and business continuity plans, conducting regular security assessments and audits, and purchasing insurance.
