Threat is an event, either an action or an inaction that leads to a negative or unwanted situation. One of the primary tasks that the CIO has for Jane is to build up the information security program. A better, more encompassing definition is the potential loss or harm related to technical infrastructure, use of technology or reputation of an organization. It is also influenced by factors attributed to other categories of risk, including strategic, budgetary, program management, investment, political, legal, reputation, supply chain, and compliance risk. The ISMS can be applied to a specific system, components of a system, or the Forensic Laboratory as a whole. Figure 1.5 shows how to apply them to our risk components illustration. Vulnerabilities can be related to the physical environment of the system, to the personnel, management, and administration procedures and security measures within the organization, to the business operations and service delivery, or to the hardware, software, or communications equipment and facilities. Impact is considered as having either an immediate (operational) effect or a future (business) effect that includes financial and market consequences. © 2020 Netwrix Corporation. Because of this diversity, it is likely that some assets that have a known monetary value (hardware) can be valued in the local currency, whereas others of a more qualitative nature (data or information) may be assigned a numerical value based on the organization’s perception of their value. NIST envisions agency risk management programs characterized by : Figure 13.2. She wasn’t expecting much. Risk assessors use these factors, in combination with past experience, anecdotal evidence, and expert judgment when available, to assign likelihood scores that allow comparison among multiple threats and adverse impacts and—if organizations implement consistent scoring methods—support meaningful comparisons across different information systems, business processes, and mission functions. For example, if a three-value scale is used, the value low can be interpreted to mean that it is not likely that the threat will occur, there are no incidents, statistics, or motives that indicate that this is likely to happen. This is due to the fact that the final report and related derivative information (e.g. For example when she was talking to the applications manager: Jane: “What security event are you worried about?”, Application Manager: “Hmmm. What things to do you have in place to protect from hackers?”, Applications Manager: “Hmmm. In other words, organizations need to: Identify Security risks, including types of computer security risks. Minimizing the risk of data breaches requires both human factors like employee training and technologies that help you secure your sensitive data, no matter where it resides. Data leakage, also known as low and slow data theft, is a huge problem for data security, and the damage caused to any organization, regardless of size or industry, can be serious. Risk and Information Security Concepts. These considerations should be reflected in the asset values. The value medium can be interpreted to mean that it is possible that the threat will occur, there have been incidents in the past or statistics or other information that indicate that this or similar threats have occurred sometime before, or there is an indication that there might be some reasons for an attacker to carry out such action. Impact is considered to have either an immediate (operational) effect or a future (business) effect that includes financial and market consequences. Jane has extensive experience in IT, particularly in application development and operations; however, she is relatively new to the information security field. As you well know, that seldom happens in the real world. Get expert advice on enhancing security, data management and IT operations. Harm, in turn, is a function of the value of the assets to the organization. Information security is the technologies, policies and practices you choose to help you keep data secure. Figure 1.6. Of even more interest to management is an analysis of the investment opportunity costs: that is, its comparison with other capital investment options.10 However, expressing risk in monetary terms is not always possible or desirable, because harm to some kinds of assets (human life) cannot (and should not) be assessed in monetary terms. As we mentioned at the beginning of this chapter each field or discipline has its own definition of risk because each field has their own perception of what risk is. In the world of risk management, risk is commonly defined as threat times vulnerability times consequence. Interest in DDM is especially high in big data projects. Subsequently, it combines this likelihood with the impact resulting from the incident occurring to calculate the system risk. Impact is related to the degree of success of the incident. One way to express asset values is to use the business impacts that unwanted incidents, such as disclosure, modification, nonavailability, and/or destruction, would have on the asset and the related business interests that would be directly or indirectly damaged. Identify threats and their level. But in order to answer the question of which ones are the “primary” risks to the organization, we need to start measuring risk through a documented and repeatable process. In this example, the full risk statement is: Unauthorized access by hackers through exploitation of weak access controls within the application could lead to the disclosure of sensitive data. Keeping sensitive company information and personal data safe and secure is not only essential for any business but a legal imperative. Assets in an organization are usually diverse. In its revised draft of Special Publication 800-30, NIST categorizes threat sources into four primary categories—adversarial, accidental, structural, and environmental—and provides an extensive (though not comprehensive) list of over 70 threat events . In many cases the readers of the report, or information derived from the report, could be anyone from executives of the company to system administrators within IT. Mark Talabis, Jason Martin, in Information Security Risk Assessment Toolkit, 2012. Risk Management Framework The selection and specification of security and privacy controls for a system is accomplished as part of an organization-wide information security and privacy program that involves the management of organizational risk---that is, the risk to the organization or to individuals associated with the operation of a system. Decibels are expressed as logarithms, and are useful in presenting data that span many orders of magnitude. By going around the table, Jane is beginning to see trends in the risks that the people in the room are most concerned with and equally as important is able to start identifying preconceptions that may be wrong. Software-based data encryption is performed by a software solution to secure the digital data before it is written to the SSD. On the other hand, the likelihood of accidental threats can be estimated using statistics and experience. Thus, risk R is a function of four elements: (1) V, the value of the assets; (2) T, the severity and likelihood of appearance of the threats; (3) V, the nature and extent of the vulnerabilities and the likelihood that a threat can successfully exploit them; and (4) I, the likely impact of the harm should the threat succeed: that is, R = f(A, T, V, I). Effective information resources management requires understanding and awareness of types of risk from a variety of sources. Data protection is an important part of a comprehensive security strategy that includes identifying, evaluating and reducing risks related to sensitive information security. It involves identifying, assessing, and treating risks to the confidentiality, integrity, and availability of an organization’s assets. Compliance requirements also drive data security. are all considered confidential information. Illustration of an Information Security Risk Statement (Unauthorized Access). The key point is that you have taken this into account during your information risk assessment and selection of security measures. Impact ratings significantly influence overall risk level determinations and can—depending on internal and external policies, regulatory mandates, and other drivers—produce specific security requirements that agencies and system owners must satisfy through the effective implementation of security controls. Data security concerns the protection of data from accidental or intentional but unauthorised modification, destruction or disclosure. Definitely not the first day Jane was expecting. Defining and communicating your board’s information risk management regime is central to your organisation’s overall cyber security strategy and the first of the ten steps. By going around the room and letting other people talk, with some gentle guiding, she was able to quickly learn quite a bit about the perception of risk within her new organization. A Data Risk Assessment Is the Foundation of Data Security Governance, [Gartner Report] A Data Risk Assessment Is the Foundation of Data Security Governance, The CIA Triad and Its Real-World Application, protect enterprise data in accordance with its value to the organization, spotting deviations from normal activity and suspicious or critical changes, The Capital One Hack: 3 Questions about Data Security in the Cloud, Top 12 Data Security Solutions to Protect Your Sensitive Information. David Watson, Andrew Jones, in Digital Forensics Processing and Procedures, 2013. Figure 1.4. Senior leaders that recognize the importance of managing information security risk and establish appropriate governance structures for managing such risk. The likelihood of human error (one of the most common accidental threats) and equipment malfunction should also be estimated. On the other hand, the likelihood of accidental threats can be estimated using statistics and experience. Depending on the size of the organization, the number of assets, and support from the organization, this phase may take a few weeks or several months. A botnet is a collection of Internet-connected devices, including PCs, mobile devices, … The organizational perspective also requires sufficient understanding on the part of senior management to recognize information security risks to the agency, establish organizational risk tolerance levels, and communicate information about risk and risk tolerance throughout the organization for use in decision making at all levels. Some would even argue that it is the most important part of the risk assessment process. Data that contain personal information should be treated with higher levels of security than data which do not, as the safeguarding of personal data is dictated by national legislation, the Data Protection Act 2018, which states that personal data should only be accessible to authorised persons. Thus, risk analysis assesses the likelihood that a security incident will happen, by analyzing and assessing the factors that are related to its occurrence, namely the threats and the vulnerabilities. Nothing on our side. Cybersecurity risk is the probability of exposure or loss resulting from a cyber attack or data breach on your organization. Thus, impact valuation is not performed separately but is rather embedded within the asset valuation process. Carl S. Young, in Information Security Science, 2016. Organizations express risk in different ways and with different scope depending on which level of the organization is involved—information system owners typically identify and rate risk from multiple threat sources applicable to their systems, while mission and business and organizational characterizations of risk may seek to rank or prioritize different risk ratings across the organization or aggregate multiple risk ratings to provide an enterprise risk perspective. Cyber and information security risk (CISR) is the risk of loss (financial/non-financial) arising from digital events caused by external or internal actors or third parties, including: Theft of information/technology assets Damage to information/technology assets Compromised integrity of … This includes identifying a strong executive sponsor or sponsors, regular follow-ups with all involved groups, building strong relationships with system owners and contacts, proper asset scoping, leveraging automated data collection mechanisms, identifying key people with strong organizational knowledge, and use of a standard control framework. For others, it could be a possible inability to protect our patient’s personal information. Because of this diversity, it is likely that some assets that have a known monetary value (hardware) can be valued in the local currency, whereas others of a more qualitative nature (data or information) may be assigned a numerical value based on the organization's perception of their value. Data mismanagement: Since security is often one of several competing alternatives for capital investment, the existence of a cost/benefit analysis that would offer proof that security will produce benefits that equal or exceed its cost is of great interest to the management of the organization. Risk managers need to consider a wide variety of threat sources and potentially relevant threat events, drawing upon organizational knowledge and characteristics of information systems and their operating environments as well as external sources of threat information. To measure risk, we adopt the fundamental principles and the scientific background of statistics and probability theory, particularly of the area known as Bayesian statistics, after the mathematician Thomas Bayes (1702–1761), who formalized the namesake theorem. Assets in an organization are usually quite diverse. Financial losses, legal issues, reputational damage and disruption of operations are among the most devastative consequences of a data breach for an enterprise. Basically, just ease into her new job and allow hereself to adjust and get a feel for the organization. After some aggressive recruiting the CIO convinced Jane to join the hospital system as their information security officer. How can you strengthen your data security? Because security is often one of several competing alternatives for capital investment, the existence of a cost–benefit analysis that would offer proof that security will produce benefits that equal or exceed its cost is of great interest to the management of the organization. Risk Management Projects/Programs. Risk is an interesting subject, linked to psychology, sociology and mathematics. Identifying, evaluating, and remediating vulnerabilities are core elements of several information security processes supporting risk management, including security control selection, implementation, and assessment as well as continuous monitoring. The definition of data security is broad. Data collection is by far the most rigorous and most encompassing activity in an information security risk assessment project. A list of some of these is given in Section 5.1. ISO 27001 requires the organisation to produce a set of reports, based on the risk assessment, for audit and certification purposes.
