The various risks that have been identified and characterized through the process of risk analysis must be considered for mitigation. Unstructured threat sources generally limit their attacks to information system targets and employ computer attack techniques. Case study: How to evaluate enterprise risk management maturity, Article: Sharpening strategic risk management, Report: Governing for performance - new directions in corporate governance, Tool: How to improve your board's effectiveness: three tools for risk and strategy governance, Report: CIMA Strategic Scorecard - boards engaging in strategy, Report: Enterprise governance - getting the balance right, "If a business has its doors open, then it is managing risk in some way. Although changing how the business operates (e.g., insuring against impacts of risks) is a valid response to risk, it is outside the scope of architecture assessment, so it will not be covered here. As the software evolves, its architecture must be kept up to date. Once a plan i… Additional system-level artifacts are also useful in the architectural risk assessment process. For software that has been fielded, data is collected about the software in its production environment, including data on system configuration, connectivity, and documented and undocumented procedures and practices. Cryptography can help, for example, when applied correctly. The broader topic of risk management is specifically addressed in the Risk Management Framework content area. Internal attacks may be executed by threat actors such as disgruntled employees and contractors. While the software industry as a whole currently lacks agreed-upon standards for precise interval scale metrics, software teams can adopt ordinal scale metrics that place events, controls, and security posture on a continuum. Embed ERM into the fabric of the organisation, Take a holistic, portfolio view of risks across the enterprise, Never treat ERM as a project – ERM is a process, Don’t get bogged down in details and history – ERM should be strategic and forward-looking, Avoid relying only on a few key staff – make ERM everyone’s job, Don’t take a silo or stove-pipe approach to risks. As platforms upgrade and evolve, each subsequent release will fix older problems and probably introduce new ones. The survey concluded that "In 57% of the cases, the insiders exploited or attempted to exploit systemic vulnerabilities in applications, processes, and/or procedures (e.g., business rule checks, authorized overrides)" [1]. Use case models help to illustrate the relationships among system components. Three activities can guide architectural risk analysis: known vulnerability analysis, ambiguity analysis, and underlying platform vulnerability analysis. It is important to note that in some cases performance degradation can be as harmful as performance interruption. The likelihood levels are described in the table below. Before discussing the process of software architectural risk assessment, it is helpful to establish the concepts and terms and how they relate to each other. Vulnerabilities take many forms, not just implementation bugs like the popular buffer overflow. The combination of threats and vulnerabilities illustrates the risks that the system is exposed to. An official website of the United States government Here's how you know. Sometimes, from a business point of view, it makes more sense to build functionality that logs and audits any successful exploits. The risk exposure statement combines the likelihood of the risk occurring with impact of the risk. Banks must start by defining the risks they face, establishing a taxonomy tailored to their business activities, assets, and risk profile. As with risk likelihood, subjective High, Medium, and Low rankings may be used to determine relative levels of risk for the organization. It also sets out the roles and responsibilities of the individuals and committees that support the risk management process. Note that not all threats exploit software failures. You can use this protocol guide to support the development of your own organization or community’s risk management protocol… "Raising the bar" in terms of the skills necessary to exploit a vulnerability is often a first step. Broad involvement on the part of board members and employees is essential in determining the risk appetite of a company, and in identifying and prioritising risks. CGMA For instance, integrity of audit records is most important (that none are added or deleted inappropriately, and that they are all accurate). Analysis should spiral outward from an asset to see what software reads, writes, modifies, or monitors that information. Completing a risk assessment can help to clarify priorities and confirm roles and responsibilities in a time when clear communication and accountability protocols will prove essential to driving focus and delivering outcomes. You will need to ensure that there are adequate resources for the implementation of the risk management architecture and protocols, and that staff are sufficiently trained and their work regularly appraised. Such an impact is localized in time and in a fraction of the merchandising side of the business. Also important are impacts to the company's marketing abilities: brand reputation damage, loss of market share, failure to deliver services or products as promised. The Build Security In (BSI) portal is sponsored by the U.S. Department of Homeland Security (DHS), National Cyber Security Division. Using information gathered through asset identification and from security best practices, the diagrams and documents gradually take shape. An attack occurs when an attacker acts and takes advantage of a vulnerability to threaten an asset. unique group of management accountants who have reached the highest Receive security alerts, tips, and other updates. Risk classification assists in communication and documentation of risk management decisions. The criteria must be objective and repeatable. New forms of loosely organized virtual hacker organizations (“hacktivists - hackers and activists”) are emerging. Risk management efforts are almost always funded ultimately by management in the organization whose primary concern is monetary. Don't give subjective opinions such as "low risk" or "high priority.". [5] R. Shirey, Security Architecture for Internet Protocols: A Guide for Protocol Designs and Standards, Internet Draft: draft-irtf-psrg-secarch-sect1-00.txt (Nov. 1994). ", -Mark S Beasley PhD, Director, ERM Initiative at North Carolina State University, January 2012, Accounting and reporting That is, what consequences will the business face if the worst-case scenario in the risk description comes to pass. You will need to ensure that there are adequate resources for the implementation of the risk management architecture and protocols, and that staff are sufficiently trained and their work regularly appraised. It is important to note that the software architecture exists in a system context that includes risks in the physical, network, host, and data layers, and risks in those layers (including those generated outside the organization’s perimeter) may cascade into the software architecture. Examples of artifact quality metrics include, but are not limited to, number of defects, number of critical risks, identified risks by type, and progress against acceptance criteria. This in turn may enable the software development team to recognize and develop countermeasures to deal with classes of vulnerabilities by dealing with the vulnerabilities at a higher level of abstraction. It is vital to acquire business statements (marketing literature, business goal statements, etc.) Ethics It is important to note that risk mitigation mechanisms may introduce threats and vulnerabilities to the system, and as such need to be analyzed. Source: How to Communicate Risks Using Heat Maps, CGMA. Architectural risk assessment is a risk management process that identifies flaws in a software architecture and determines risks to business information assets that result from those flaws. Internal threat agents currently account for the majority of intentional attacks against government and commercial enterprises. As a management process, risk management is used to identify and avoid the potential cost, schedule, and performance/technical risks to a system, take a proactive and structured approach to manage negative outcomes, respond to them if they occur, and identify potential opportunities that may be hidden in the situation . Deception: risks that involve unauthorized change and reception of malicious information stored on a computer system or data exchanged between computer systems. It is further obvious that the company risks ill-will with its customers or must pay customer service representatives for extra time dealing with higher aggregate call volume when the software fails and remains unavailable for significant amounts of time. Risk Management Protocols. The risk management strategy and policy is supported and operationalized through a risk management architecture. The need for software is expressed and the purpose and scope of the software is documented. The software is designed, purchased, programmed, developed, or otherwise constructed. Common impacts to information assets include loss of data, corruption of data, unauthorized or unaudited modification of data, unavailability of data, corruption of audit trails, and insertion of invalid data. These individuals are not looking to target specific information or a specific company but rather use knowledge of a vulnerability to scan the entire Internet for systems that possess that vulnerability. Insider Threat Study: Computer System Sabotage in Critical Infrastructure Sectors, May 2005, http://www.secretservice.gov/ntac_its.shtml. Management responsibilities include the risk architecture or infrastructure, documentation of procedures or risk management protocols, training, monitoring and reporting on risks and risk management activities. Sometimes processes are depicted using a state diagram, in order to validate that all states are covered by code, by tests, or by requirements. List the top activities you perform in your position that you consider to be high risk activities. For example, simple userids and passwords can be compromised much more easily than most two-factor authentication systems. In the end, the goal of the application characterization activity is to produce one or more documents that depict the vital relationships between critical parts of the system. The body of known attack patterns is always growing, thus continued success in known vulnerability analysis is dependent on remaining current in software security trends. A mitigation plan is composed of countermeasures that are considered to be effective against the identified vulnerabilities that the threats exploit. What internal factors or events could impede or derail each of these components? Some organizations value confidentiality of data most highly, while others demand integrity and availability. Furthermore, the analysis must account for other credible scenarios that are not the worst case yet are bad enough to warrant attention. For example, changing authentication mechanisms from userid and password to pre-shared public key certificates can make it far more difficult to impersonate a user. When performing known vulnerability analysis, consider the architecture as it has been described in the artifacts that were reviewed for asset identification. the world with more than 137,000 designees. Risk architecture. Whether the vulnerabilities are exploited intentionally (malicious) or unintentionally (non-malicious) the net result is that the confidentiality, integrity, and/or availability of the organization’s assets may be impacted. Organizations may seek to accept the risk as a “cost of doing business,” or they may choose to outsource risk via insurance or contractual means, or the risk may be mitigated partially. The types of vulnerabilities that will exist and the methodology needed to determine whether the vulnerabilities are present will vary depending on which phase in the SDLC the risk assessment occurs. Many nodes are categorized as a data center. It is of paramount importance to characterize that impact in as specific terms as possible. Risk analysis can be implemented as an iterative process where information collected and analyzed during previous assessments are fed forward into future risk analysis efforts. It shows the major components, their relationships and has a few well chosen labels and text boxes that portray the design philosophies embodied in the architecture. In the requirements phase, the search for vulnerabilities should focus on the organization’s security policies, planned security procedures, non-functional requirement definitions, use cases, and misuse and abuse cases. The risk exposure statement generalizes the overall exposure of the organization for the given risk and offers more granular visibility to both impact and likelihood. Architecture's role is to eliminate the potential misunderstandings between business requirements for software and the developers' implementation of the software's actions. In the case of architectural flaws, however, significant redesign is usually necessary to solve the problem. 7 Risk management policy 67 Risk architecture, strategy and protocols 67 Risk management policy 69 Risk management architecture 72 Risk management strategy 72 Risk management protocols 73 Risk management guidelines 74 8 Risk management documentation 76 Record of risk management activities 76 Risk response and improvement plans 77 However, that does not mean the organization has an enterprise-wide, holistic and strategic approach to risk management. [6] Address to the Garn Institute of Finance, University of Utah, November 30, 1994. Three prominent vendor risk management experts will also share tips and best practices in a variety of fields, including the medical field, where HIPAA compliance can be a huge risk. Risk management is the process of continually assessing and addressing risk throughout the life of the software. Unmitigated vulnerabilities require risk management planning to deal with impacts to assets. Threats are agents that violate the protection of information assets and site security policy. 3. The system description is informed by the underlying security infrastructure or future security plans for the software. Can you apply any risk management techniques to these activities? http://csrc.nist.gov/publications/nistpubs/800-30/sp800-30.pdf (2002). Thus, when a flaw is found, the fix usually requires agreement across multiple teams, testing of multiple integrated modules, and synchronization of release cycles that may not always be present in the different modules. Contain units of measure. Failure to authenticate between multiple cooperating applications, however, is an architectural flaw that cannot be trivially remedied. The goal of this step is to develop a list of application or system vulnerabilities that could be accidentally triggered or intentionally exploited and result in a security breach or a violation of the system’s security policy. 7 Risk management policy 67 Risk architecture, strategy and protocols 67 Risk management policy 69 Risk management architecture 72 Risk management strategy 72 Risk management protocols 73 Risk management guidelines 74 8 Risk management documentation 76 Record of risk management activities 76 Risk response and improvement plans 77 Data export message passing between five processes. That management determines what the software's goals are and what constraints it operates in. Risk management categorizes the controls that mitigate risks and tracks their efficacy over time through testing, log analysis, auditing, and other means. Cigital retains copyrights to this material. IDENTIFY. This document is part of the US-CERT website archive. A mitigation consists of one or more controls whose purpose is to prevent a successful attack against the software architecture’s confidentiality, integrity, and availability. Alan Greenspan, Chairman of the Federal Reserve Board, said this in 1994: There are some who would argue that the role of the bank supervisor is to minimize or even eliminate bank failure; but this view is mistaken in my judgment. What is important is to collect as many as possible. Risk analysis can be conducted on a scheduled, event-driven, or as needed basis. Independent of the life-cycle phase, online vulnerability references should be consulted. Nonetheless, the concept of likelihood can be useful when prioritizing risks and evaluating the effectiveness of potential mitigations.
