NIST IR 7298 Revision 1, Glossary of Key Information Security Terms Risk Management – The process of managing risks to organizational operations (including mission, functions, image, reputation), organizational assets, individuals, other organizations, and the Nation, resulting from the operation of an information system, and includes: (i) the conduct of a risk assessment; (ii) the implementation of a risk mitigation strategy; and (iii) employment of techniques and procedures for the continuous monitoring of the security state of the information system. SOURCE: SP 800-53; SP 800-53A; SP 800-37 Risk Management – The process of managing risks to organizational operations (including mission, functions, image, or reputation), organizational assets, or individuals resulting from the operation of an information system, and includes: 1) the conduct of a risk assessment; 2) the implementation of a risk mitigation strategy; and 3) employment of techniques and procedures for the continuous monitoring of the security state of the information system. SOURCE: FIPS 200 Risk Management – The process of managing risks to agency operations (including mission, functions, image, or reputation), agency assets, or individuals resulting from the operation of an information system. It includes risk assessment; cost-benefit analysis; the selection, implementation, and assessment of security controls; and the formal authorization to operate the system. The process considers effectiveness, efficiency, and constraints due to laws, directives, policies, or regulations. SOURCE: SP 800-82; SP 800-34 The process of managing risks to organizational operations (including mission, functions, image, or reputation), organizational assets, individuals, other organizations, or the nation resulting from the operation or use of an information system, and includes: (1) the conduct of a risk assessment; (2) the implementation of a risk mitigation strategy; (3) employment of techniques and procedures for the continuous monitoring of the security state of the information system; and (4) documenting the overall risk management program.

NIST IR 7298 Revision 1, Glossary of Key Information Security Terms Risk Mitigation – Risk mitigation involves prioritizing, evaluating, and implementing the appropriate risk-reducing controls recommended from the risk assessment process. SOURCE: SP 800-30 Prioritizing, evaluating, and implementing the appropriate riskreducing controls/countermeasures recommended from the risk management process. SOURCE: CNSSI-4009 Risk Tolerance – The level of risk an entity is willing to assume in order to achieve a potential desired result. SOURCE: SP 800-32 The defined impacts to an enterprise’s information systems that an entity is willing to accept. SOURCE: CNSSI-4009 Robust Security Network (RSN) – A wireless security network that only allows the creation of Robust Security Network Associations (RSNAs). SOURCE: SP 800-48 Robust Security Network Association (RSNA) – A logical connection between communicating IEEE 802.11 entities established through the IEEE 802.11i key management scheme, also known as the four-way handshake. SOURCE: SP 800-48 Robustness – The ability of an Information Assurance entity to operate correctly and reliably across a wide range of operational conditions, and to fail gracefully outside of that operational range. SOURCE: CNSSI-4009 Rogue Device – An unauthorized node on a network. SOURCE: SP 800-115 Role – A group attribute that ties membership to function. When an entity assumes a role, the entity is given certain rights that belong to that role. When the entity leaves the role, those rights are removed. The rights given are consistent with the functionality that the entity needs to perform the expected tasks. SOURCE: CNSSI-4009 Pg 161
