Risk Management Framework is implemented throughout an organization.
NIST 800-39, Manage Information Security Risk, describes how to implement risk within t three layers (or tiers) of of an organization:
Tier 1: Organization level
Tier 2: Mission/Business Process level
Tier 3: Information System level
Tier 1: Organization Level risk management
Tier one addresses security from the organizations perspective. The activities include the implementation of the first component of risk management, risk framing. Risk framing provides context of all the risk activities within an organization, which affects the risk activities of tier 1 & 2. The output of risk framing is Risk Management Strategy. In tier 1 the organization establishes and implements governance structure that are in compliance with laws, regulations and policies. Tier 1 activities include establishment of the Risk Executive Function, establishment of the risk management strategy and determination of the risk tolerance.
Tier 2: Mission/Business Process Level risk management
Tier 2 risk management activities include: 1) defining the mission/business processes to support the organization. 2) Prioritize the mission/business process with respect to the long term goals of the organization. 3) Define the type of information needed to successfully execute the mission/business processes, criticality/sensitivity of the information and the information flows both internal and external of the information.
Having a risk-aware process is an important part of tier 2. To be risk-aware senior leaders/executives need to know: 1) types of threat sources and threat events that could have an adverse affect the ability of the organizations 2) the potential adverse impacts on the organizational operations and assets, individuals, the Nation if confidentiality, integrity, availability is compromised 3) the organization�s resilience to such an attack that can be achieved with a given mission/business process
Tier 3: Information System risk management
From the information system perspective, tier 3 addresses the following tasks:
1) Categorization of the information system
2) Allocating the organizational security control
3) Selection, implementation, assessment, authorization, and ongoing
Chapter 3 focuses on the step to have a comprehensive risk management program. The tasks discussed include:

DIACAP is transitioning from a Certification and Accreditation to a Risk Management Framework. Most of the new Risk Manager Framework is in the NIST Special Publication 800-37. The old NIST SP 800-37 was also based on Certification and Accreditation. After FISMA 2002, it adjusted to a Risk Management Framework in NIST SP 800-37 Rev 1, Guide for Applying the Risk Management Framework to Federal Information Systems.
NIST SP 800-37 to SP 800-37 rev 1 transformed from a Certification and Accreditation (C&A) process into the six-step Risk Management Framework (RMF). The changes included:
- Revised process emphasizes
- Building information security capabilities into federal information systems through the application of state-of-the-practice management, operational, and technical security controls
- Maintaining awareness of the security state of information systems on an ongoing basis though enhanced monitoring processes
- Providing essential information to senior leaders to facilitate decisions regarding the acceptance of risk to organizational operations and assets, individuals, other organizations, and the Nation arising from the operation and use of information systems
Information Assurance is based on obtaining a high level of confidence on information’s confidentiality, integrity, and availability. Some organizations that deal with “critical information”. Critical information included things like banking transactions, classified data, information that is evidence in an ongoing investigation. Companies, unions and government that handle this kind of information usually have a lot of exposure because they are handling public data, share holder data, employee data and are doing a lot of translation across the un-trusted networks such as the Internet. With critical information and high exposure these organizations MUST have “approved processes” for vetting, testing and validating “approved software” and “approved systems”.
For example, in the Department of Defense there are many lists that have approved software. These lists are per command within larger organizations. One over arching process/list is the Common Criteria:
Common Criteria is an international standard for validating technical security built in to security feature of information systems. The international standard is known as ISO/IEC 15408.
This standard is used by many large organizations all over the world that serve the public:
Each organization has there own specific security needs so most of the time they have many levels of application approval and process:
NSA / DOD / US Gov – www.niap-ccevs.org – National Information Assurance Partnership (NIAP) uses Common Criteria Evaluation and Validation Scheme (CCEVS) to ensure that only approved Information Assurance (IA) and IA-Enabled Information Technology (IT) products are used
Canadian Trusted Computer Product Evaluation Criteria
UK – http://www.cesg.gov.uk/servicecatalogue/ccitsec
Commercial organizations that want their products used by organization processing and storing critical information must submit to common criteria as well:
Apple – https://ssl.apple.com/support/security/commoncriteria/
Microsoft – http://www.microsoft.com/en-us/sqlserver/common-criteria.aspx
xerox – Common Criteria
Citrix – http://www.citrix.com/support/security-compliance/common-criteria.html
Cisco – Cisco Common Criteria
Emc – EMC – Common Criteria
Organizational units also have their own criteria for approved applications and systems:
US Army – Army Chess
US Air Force – AF E/APL – Certified Air Force Evaluated Approved Product List
