Many of the management and operational controls needed to protect an information system can be used for regulatory compliance, risk assessment, and security policy development.
Step-by-step explanation:
Many of the management and operational controls needed to protect an information system, such as contingency planning controls, incident response controls, security awareness and training controls, personnel security controls, and physical security controls, are excellent candidates for Regulatory compliance because they help organizations meet and adhere to the requirements set by regulations and standards.
These controls can also be used for Risk assessment in order to identify potential vulnerabilities and threats, evaluate the likelihood and impact of those risks, and determine appropriate mitigation measures to reduce the overall risk.
