risk architecture, strategy and protocols

[1] Michelle Keeney, JD, PhD, et al. ISO 31000:2009 can be applied throughout the life of an organization, and to a wide range of activities, including strategies and decisions, operations, processes, functions, projects, products, services and assets. Other threats are not conscious entities but must still be considered: hardware failures, performance delays, natural disasters, force majeure, and user errors. Information assets are identified. Risk mitigation planning, implementation, and progress monitoring are depicted in Figure 1. Commit log is used for crash recovery. IDENTIFY. The willingness to take risk is essential to the growth of the free market economy…[i]f all savers and their financial intermediaries invested in only risk-free assets, the potential for business growth would never be realized [6]. The various risks that have been identified and characterized through the process of risk analysis must be considered for mitigation. For example, a static code checker can flag bugs like buffer overflows. Here are several principles toward effective risk management: IDENTIFY. IT architecture is a series of … Three activities can guide architectural risk analysis: known vulnerability analysis, ambiguity analysis, and underlying platform vulnerability analysis. Transnational threats are generated by organized non-state entities, such as drug cartels, crime syndicates, and terrorist organizations. Thus underlying platform vulnerability analysis must continue throughout the life of the product. 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 . This ability to characterize the mitigation's cost, however, is of little value unless the cost of the business impact is known. management policy and strategy. [3] R. Abbott, J.Chin, J. Donnelley, W. Konigsford, S. Tokubo, and D.

Risk management is an essential element of the strategic management of any organisation and should be embedded in the ongoing activities of the business. Risk management is making and carrying out decisions that minimize the likelihood and/or severity of financial loss due to professional liability lawsuits. Threats may be mapped to vulnerabilities to understand how the system may be exploited. An architectural risk assessment must include an analysis of the vulnerabilities associated with the application's execution environment. When credible threats can be combined with the vulnerabilities uncovered in this exercise, a risk exists that needs further analysis and mitigation. There are also several web sites that aggregate vulnerability information. In the event that data is exported, a logging subsystem is activated to write log entries to record the fact that data was exported. For example, the number of risks identified in various software artifacts and/or software life-cycle phases is used to identify problematic areas in software process. Is the user suddenly and forcibly logged out, or is the active session still valid until the user logs out? The threat might lack motivation or capability. Two or more of the three qualities are compensating. However, the audit committee chair suggested that the next step be an evaluation of the risk management process and the degree of its integration with the strategic management process of the organisation, leading to the use of the CGMA Risk Management Maturity tool. Errors and omissions are the authors’. Risk management is the process of continually assessing and addressing risk throughout the life of the software. Since it is based on past experience, this likelihood cannot account for new types of attacks or vulnerabilities that have not yet been discovered. 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. All categories of threats should be considered, but malicious and accidental human activities usually get the most attention. Internal attacks may be executed by threat actors such as disgruntled employees and contractors. The authentication and authorization architecture must be compared to the actual implementation to learn which way this question was decided. It was established in 2.1 Risk architecture, strategy and protocols 2.2 Risk management documentation and responsibilities Explain how the risk architecture, strategy and protocols contribute to effective risk management Explain the value of comprehensive and effective risk documentation and the assignment of risk … 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. The following factors must be considered in the likelihood estimation: the vulnerability's directness and impact. Likewise, the number of risks mitigated over time is used to show concrete progress as risk mitigation activities unfold. Without knowing what assets need protection, and without knowing what happens when the protection fails, the rest of the risk analysis techniques cannot produce worthwhile results. A mitigation consists of one or more controls whose purpose is to prevent a successful attack against the software architecture… That is, what consequences will the business face if the worst-case scenario in the risk description comes to pass. Every application platform and operating system has a mailing list and a web site where up-to-date vulnerability information can be found. To identify information assets, one must look beyond the software development team to the management that directs the software's evolution. Risk management is composed of point-in-time and ongoing processes. The diagram below shows the process view of risk analysis and risk management areas. Software can also be vulnerable because of a flaw 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. 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. The risk assessment methodology encompasses six fundamental activity stages: Assessing the architectural risks for a software system is easier when the scope of the architecture is well defined. Defining its scope is the role of application characterization. Many mitigations can be described either as detection or correction strategies. The risk management strategy and policy is supported and operationalized through a risk management architecture. An asset is referred to in threat analysis parlance as a threat target. Risk management is an iterative process that responds to a rapidly evolving situation. He asked them to assess the likelihood and potential impact of the identified risks. Example business impacts include failing to control access to medical records, thus exposing the business to liability to lawsuits under the Health Insurance Portability and Accountability Act (HIPAA); and a race condition in order insertion and order fulfillment operations on the orders database that causes orders to be duplicated or lost. Traditionally, security practitioners concern themselves with the confidentiality, integrity, availability, and auditability of information assets. [6] Address to the Garn Institute of Finance, University of Utah, November 30, 1994. Consider it against a body of known bad practices or known good principles for confidentiality, integrity, and availability. and requirements-phase artifacts (use cases, user stories, requirements). Michael, John S. Quarterman, and Adam Shostack are gratefully acknowledged. The threat's motivation and capability vary widely. Static code checkers, runtime code checkers, profiling tools, penetration testing tools, stress test tools, and application scanning tools can find some security bugs in code, but they do not address architectural problems. Governance and risk 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 An organisation will describe its framework for supporting risk management by way of the risk architecture, strategy and protocols (RASP). Structured external threats are generated by a state-sponsored entity, such as a foreign intelligence service. star outlined. Ever-changing tools, techniques, protocols, standards, and development systems increase the probability that technology risks will arise in virtually any substantial software engineering effort. The other concerns cascade failure, where failures in a technical system like the Domain Name Service or a business system like the general ledger may cascade across other systems and domains. Here's how Ian Gorton defines marketecture in his book, Essential Software Architecture: (a) one page, typically informal depiction of the system's structure and interactions. 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. You can use this protocol guide to support the development of your own organization or community’s risk management protocol… While 5G architecture is designed to be more secure, 5G’s specifications and protocols stem from previous networks, which contain legacy vulnerabilities. Likewise, laws and policies apply differently depending on where data is stored and how data exposures happen. Performance management If a protocol contains therapeutic or nontherapeutic components that exceed minimal risk, then a component analysis is required. There are a number of processes available for software risk identification, including the use of automated tools and the application of checklists and guidelines. Independent of likelihood and controls, the risk's impact must be determined. You will also need to ensure that risk management is embedded in your organisation, that it aligns with business objectives and that it delivers value. Some threat actors are external, and may include structured external, transnational external, and unstructured external threats, which are described below. That management determines what the software's goals are and what constraints it operates in. Risk Analysis can be complex, as you'll need to draw on detailed information such as project plans, financial data, security protocols, marketing forecasts, and other relevant information. Risk management uses artifacts created in the risk analysis process to evaluate criteria that can be used to make risk management decisions. Through a series of interviews with business representatives, the initial information regarding assets should be discovered. In practice, this means assessing vulnerabilities not just at a component or function level, but also at interaction points. Their support and understanding can be assured only by driving software risks out to fiscal impacts. Do we have the right systems and processes in place to address these internal and external risks? Analysis should spiral outward from an asset to see what software reads, writes, modifies, or monitors that information. Risk responses include: acceptance or tolerance of a risk; avoidance or termination of a risk; risk transfer or sharing via insurance, a joint venture or other arrangement; and reduction or mitigation of risk via internal control procedures or other risk prevention activities. Risk management is an ongoing process that uses risk analysis, mitigations, metrics, and other processes and tools to manage risk for the organization. For example, a failure in the application server might only prevent new orders from being placed, while orders that are already placed can be fulfilled and customer service staff can see, modify, and update existing orders. The emphasis is on risk analysis. Using information gathered through asset identification and from security best practices, the diagrams and documents gradually take shape. EVALUATE. Source: How to Communicate Risks Using Heat Maps, CGMA. As part of an iterative process, the risk tracking tool is used to record the results of risk prioritization analysis (step 3) that provides input to both risk mitigation (step 4) and risk impact assessment (step 2).The risk mitigation step involves development of mitigation plans designed to manage, eliminate, or reduce risk to an acceptable level. These include, but are not limited to, the following: functional and non-functional requirements, software architecture documents describing logical, physical, and process views, detailed design documents such as UML diagrams that show behavioral and structural aspects of the system, identity services and management architecture documents, It is often the case that a given software project does not have all of these artifacts. The process of risk management is centered around information assets. The Architectural Risk Management section describes the actual process of risk management, which is broken down into the Asset Identification, Risk Analysis, and Risk Mitigation sections. All the information assets that can be found should be gathered in a list to be coordinated with risk analysis. Give the results as a percentage, ratio, or some other kind of actual measurement. ANALYZE. The model should address strategy, governance and organization, risk management, risk architecture, and culture. Some complex risks spring to mind easily: a malicious attacker (threat) bypasses the authentication module (vulnerability) and downloads user accounts (information asset), thereby exposing the business to financial liability for the lost records (impact). Risk Strategy. Other important ERM concepts include the risk philosophy or risk strategy, risk culture and risk appetite. The . Protocol guide for risk management A risk management protocol should be implemented in cases where a youth is identified or suspected to be at risk for suicide. 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. Cryptography can help, for example, when applied correctly. A focus on correction would add business logic to validate input and make sure that the software module never received input that it could not handle. The risks identified during this phase can be used to support the security analyses of the software and may lead to architecture or design tradeoffs during development. Attackers who are not technologically sophisticated are increasingly performing attacks on systems without really understanding what it is they are exploiting, because the weakness was discovered by someone else. 2. Banks must start by defining the risks they face, establishing a taxonomy tailored to their business activities, assets, and risk profile. 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. Threats are nouns: agents that violate the protection of information assets. For example, a requirement for a web application might state that an administrator can lock an account and the user can no longer log in while the account remains locked. In the case of architectural flaws, however, significant redesign is usually necessary to solve the problem. A mitigation consists of one or more controls whose purpose is to prevent a successful attack against the software architecture… Adding a second authentication factor raises the bar for a would-be threat. Impacts can sometimes be localized in time or within business and technical boundaries. Roles and responsibilities; Communication plan; Reporting plan; Risk management policy. As with risk likelihood, subjective High, Medium, and Low rankings may be used to determine relative levels of risk for the organization. Figure 2 shows a set of five processes that intercommunicate to determine whether data may be exported. Copyright © Cigital, Inc. 2005-2007. Risks are considered in the system requirements, including non-functional and security requirements, and a security concept of operations. 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. Impacts are consequences that the business must face if there is a successful attack. Insider Threat Study: Computer System Sabotage in Critical Infrastructure Sectors, May 2005, http://www.secretservice.gov/ntac_its.shtml. 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. A framework and set of guidelines to build new systems. Threats may target these risk classes: Disclosure: the dissemination of information to an individual(s) for whom the information should not be seen. Ongoing monitoring and concise reporting on key risk exposures are essential for effective risk management. Risk architecture. The risk architecture, strategy and protocols (RASP) provides details of the risk management framework which helps to define the RM context. Reducing the likelihood of a risk can take several forms. It sets out the roles and responsibilities of the individuals and committees that support the risk management process. [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). An attack occurs when an attacker acts and takes advantage of a vulnerability to threaten an asset. NodeNode is the place where data is stored. One is risks that may impact a domain system, such as a national or enterprise-wide system, that is by its nature a single point of failure (for example, a Red Telephone that fails to ring). 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. Perhaps diagram the system's major modules, classes, or subsystems and circle areas of high privilege versus areas of low privilege. Mem-tableAfter data written in C… However, that does not mean the organization has an enterprise-wide, holistic and strategic approach to risk management. This website has been developed by the AICPA and CIMA and is subject to license agreements between the AICPA, CIMA and the Association of International Certified Professional Accountants. Sometimes processes are depicted using a state diagram, in order to validate that all states are covered by code, by tests, or by requirements. The important point is to note places where the requirements are ambiguously stated and the implementation and architecture either disagree or fail to resolve the ambiguity. 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. Internal threat actors can act on their own or under the direction of an external threat source (for example, an employee may install a screensaver that contains a Trojan horse). For an application under development, it is necessary to define key security rules and attributes. Mitigations can often be characterized well in terms of their cost to the business: man-hours of labor, cost of shipping new units with the improved software, delay entering the market with new features because old ones must be fixed, etc. These assets can be personal information about customers, financial information about the company itself, order information that the company needs in order to fulfill orders and collect revenue, or perhaps accounting information that must be managed carefully to comply with federal law. Risk management and risk transfer instruments deal with unmitigated vulnerabilities. Mitigation is never without cost. In the first year of implementation, the ERM team met with senior management, and identified and prioritised a number of crucial risks that had been disruptive to GMS. Risk is a product of the probability of a threat exploiting a vulnerability and the impact to the organization. Some threats are well known and obvious: crackers, disgruntled employees, criminals, and security auditing tools that probe potential vulnerabilities. Nonetheless, the concept of likelihood can be useful when prioritizing risks and evaluating the effectiveness of potential mitigations. Mitigating a risk means changing the architecture of the software or the business in one or more ways to reduce the likelihood or the impact of the risk. Acknowledgements. Data CenterA collection of nodes are called data center. Many nodes are categorized as a data center. Ambiguity analysis is always necessary, though over time it can focus on just new requirements or new functionality that is being added. 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 addition to characterizing the monetary impact, the location in other dimensions may be useful or required. Risk management has an ongoing operational component where system and business metrics and events are monitored over time that may alter and evolve the organization’s risk management posture to levels of risk that are acceptable to the organization. A master list of risks should be maintained during all stages of the architectural risk analysis. The boundaries of the software system are identified, along with the resources, integration points, and information that constitute the system. What is Risk Management? It cannot identify security vulnerabilities like transitive trust. Ordinal scale metrics provide data that can be used to drive decision support by allowing visibility and modeling of the ranking of security metrics. ... (RDP) without exposing the VMs directly to the internet. These principles support these three key strategies and describe a securely architected system hosted on cloud or on-premises datacenters (or a combination of both). Sometimes, from a business point of view, it makes more sense to build functionality that logs and audits any successful exploits. The resulting report was well received. Consider the boundaries between these areas and the kinds of communications across those boundaries. This is built around and supports the risk management process. Once a plan i… Risk mitigation mechanisms deal with one or more risk categories. What are the main components or drivers of our business strategy? Some organizations value confidentiality of data most highly, while others demand integrity and availability. System design documents and the system security plan can provide useful information about the security of software in the development phase. Mitigation of a risk means to change the architecture of the software or the business in one or more ways to reduce the likelihood or the impact of the risk. A clear and simple segmentation strategy helps contain risk while enabling productivity and business operations. Threats and vulnerabilities conspire to participate in one or more risk categories. Risk Management Protocols. It is intuitively obvious that availability is important to the customer accounts database. ... defines the overall objectives that the organisation is trying to achieve with respect to risk management. The risk management plan describes how risk management will be structured and performed on the project [2]. CGMA 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. Deception: risks that involve unauthorized change and reception of malicious information stored on a computer system or data exchanged between computer systems. Risk management begins by identifying the assets that must be protected. The risk architecture, strategy and protocols shown in Figure 1 represent the internal arrangements for communicating on risk issues. Stephen D. Gantz, Daniel R. Philpott, in FISMA and the Risk Management Framework, 2013. The three qualities are all weak: a threat is highly motivated and sufficiently capable, a vulnerability exists that is severe and direct, and controls to prevent the vulnerability from being exploited are ineffective. ClusterThe cluster is the collection of many data centers. star outlined. 5. Andrew Jaquith [7] provides guidelines that security metrics must adhere to: Be consistently measured. Using automated tools (such as scanning software or password crackers) helps. The assets threatened by the impact of this risk, and the nature of what will happen to them, must be identified. During each of these phases, business impact is the guiding factor for risk analysis. It is often not practically possible to model and depict all interrelationships. The results of the risk analysis help identify appropriate controls for reducing or eliminating risk during the risk mitigation process.
