A threat analysis will best identify the external influences to an organization's information security because it involves identifying and evaluating the sources and likelihood of potential adverse events that could affect the organization's assets, operations, or reputation.External influences include factors such as emerging technologies, social media, business environment, risk tolerance, regulatory requirements, third-party considerations, and threat landscape1. A threat analysis can help the organization to align its information security strategy with its business objectives and risk appetite, and to prioritize and mitigate the most relevant and impactful threats. A business impact analysis (BIA) is a process of assessing the potential consequences of a disruption to the organization's critical business functions or processes. A BIA does not directly identify the external influences to the organization's information security, but rather the impact of those influences on the organization's continuity and recovery. A gap analysis is a process of comparing the current state of the organization's information security with a desired or expected state, based on best practices, standards, or frameworks. A gap analysis does not directly identify the external influences to the organization's information security, but rather the areas of improvement or compliance. A vulnerability analysis is a process of identifying and evaluating the weaknesses or flaws in the organization's information systems or processes that could be exploited by threats.A vulnerability analysis does not directly identify the external influences to the organization's information security, but rather the exposure or susceptibility of the organization to those influences.Reference= CISM Review Manual, 15th Edition, pages 22-232; CISM Exam Content Outline, Domain 1, Knowledge Statement 1.113

Threat analysis is a process that is used to identify and assess the external influences or threats that could potentially affect an organization's information security. It is used to identify potential risks and develop strategies to mitigate or reduce those risks. Threat analysis involves analyzing the environment, identifying potential threats and their potential impacts, and then evaluating the organization's current security measures and developing strategies to address any deficiencies.

Email software packages that provide native encryption of messages use proprietary algorithms and formats that are not compatible with other email software packages. This means that the encryption cannot interoperate across product domains, and the recipients of encrypted messages must use the same email software package as the sender to decrypt and read the messages. This limits the usability and scalability of native encryption, and may also pose security risks if the encryption algorithms or formats are not well-tested or widely accepted.A common drawback of email software packages that provide native encryption of messages is that the encryption cannot interoperate across product domains1234.Reference= CISM Review Manual 15th Edition, page 206.The Top 10 Email Encryption Solutions In 2023 - Expert Insights2, The Best Email Encryption Services for 2023 | PCMag3, The Top 12 Email Encryption Services for 2023 - Right Inbox4.

A common drawback of email software packages that provide native encryption of messages is that the encryption cannot interoperate across product domains. This means that emails sent from one product cannot be read by another product, as the encryption keys used are not compatible. This can be a problem when sending emails to people who use different software packages, as the encrypted emails cannot be read.

A business impact analysis (BIA) is a process that identifies and evaluates the potential effects of disruptions to critical business operations as a result of a disaster, accident, emergency, or threat. A BIA helps to determine the business continuity requirements and priorities for recovery of business functions and processes, including their dependencies on IT systems, applications, and data. A BIA also provides information on the financial and operational impacts of a disruption, the recovery time objectives (RTOs), the recovery point objectives (RPOs), and the minimum service levels for each business function and process. A BIA is an essential input for designing a disaster recovery plan (DRP), which is a documented and approved set of procedures and arrangements to enable an organization to respond to a disaster and resume its critical functions within a predetermined timeframe. A DRP must be based on the BIA results to ensure that the system restoration is prioritized according to the business needs and expectations. A DRP must also consider the availability and suitability of the recovery resources, such as backup systems, alternate sites, and personnel.A DRP should be tested and updated regularly to ensure its effectiveness and alignment with the changing business environment and requirements.Reference= CISM Review Manual, 15th Edition, pages 175-1761; CISM Review Questions, Answers & Explanations Database, question ID 2182; Working Toward a Managed, Mature Business Continuity Plan - ISACA3; Part Two: Business Continuity and Disaster Recovery Plans - CISM Foundations: Module 4 Course4.

A BIA is an important part of Disaster Recovery Planning (DRP). It helps identify the impact of a disruption on the organization, including the critical systems and processes that must be recovered in order to minimize that impact. The BIA results are used to prioritize system restoration and determine the resources needed to get the organization back into operation as quickly as possible.

An information security post-incident review is a process that aims to identify the root causes, impacts, lessons learned, and improvement actions of a security incident. The highest priority during a post-incident review should be evaluating the effectiveness of the incident response, which means assessing how well the incident response plan, procedures, roles, resources, and communication were executed and aligned with the business objectives and requirements. Evaluating the incident response effectiveness can help to identify the gaps, weaknesses, strengths, and opportunities for improvement in the incident response process and capabilities. Documenting actions taken in sufficient detail, updating key risk indicators (KRIs), and evaluating the performance of incident response team members are also important activities during a post-incident review, but they are not as critical as evaluating the incident response effectiveness, which can provide a holistic and strategic view of the incident response maturity and value.

During post-incident reviews, the highest priority should be given to evaluating the effectiveness of the incident response effort. This includes assessing the accuracy of the response to the incident, the timeliness of the response, and the efficiency of the response. It is important to assess the effectiveness of the response in order to identify areas for improvement and ensure that future responses can be more effective. Documenting the actions taken in sufficient detail, updating key risk indicators (KRIs), and evaluating the performance of incident response team members are all important components of a post-incident review, but evaluating incident response effectiveness should be given the highest priority.

The main reason for having senior management review and approve an information security strategic plan is to ensure that the plan aligns with the corporate governance of the organization.Corporate governance is the set of responsibilities and practices exercised by the board and executive management to provide strategic direction, ensure objectives are achieved, manage risks appropriately and verify that the organization's resources are used responsibly1.An information security strategic plan is a document that defines the vision, mission, goals, objectives, scope and approach for the information security program of the organization2.The plan should be aligned with the organization's business strategy, risk appetite, culture, values and objectives3.By reviewing and approving the plan, senior management demonstrates their commitment and support for the information security program, ensures its alignment with the corporate governance, and provides the necessary resources and authority for its implementation4.Reference=1: CISM Review Manual 15th Edition, ISACA, 2017, page 172: CISM Review Manual 15th Edition, ISACA, 2017, page 253: CISM Review Manual 15th Edition, ISACA, 2017, page 264: CISM Review Manual 15th Edition, ISACA, 2017, page 27.

Senior management review and approval of an information security strategic plan is important to ensure that the plan is aligned with the organization's overall corporate governance objectives. It is also important to ensure that the plan takes into account any legal and regulatory requirements, as well as the resources and staff needed to properly implement the plan.

To support effective risk decision making, it is most important to have risk reporting procedures in place. Risk reporting procedures define how, when, and to whom risk information is communicated within the organization. Risk reporting procedures ensure that risk information is timely, accurate, consistent, and relevant for the decision makers. Risk reporting procedures also facilitate the monitoring and review of risk management activities and outcomes. Risk reporting procedures enable the organization to align its risk appetite and tolerance with its business objectives and strategies. Established risk domains are not the most important factor for effective risk decision making. Risk domains are categories or areas of risk that reflect the organization's structure, objectives, and operations. Risk domains help to organize and prioritize risk information, but they do not necessarily support the communication and analysis of risk information for decision making. An audit committee consisting of mid-level management is not the most important factor for effective risk decision making. An audit committee is a subcommittee of the board of directors that oversees the internal and external audit functions of the organization. An audit committee should consist of independent and qualified members, preferably from the board of directors or senior management, not mid-level management. An audit committee provides assurance and oversight on the effectiveness of risk management, but it does not directly support risk decision making. Well-defined and approved controls are not the most important factor for effective risk decision making. Controls are measures or actions that reduce the likelihood or impact of risk events. Well-defined and approved controls are essential for implementing risk responses and mitigating risks, but they do not directly support the identification, analysis, and evaluation of risks for decision making.Reference= CISM Review Manual 15th Edition, page 207-208.

Established risk domains are important for effective risk decision making because they provide a basis for categorizing risks and assessing their impact on the organization. Risk domains are also used to assign risk ownership and prioritize risk management activities. Having established risk domains in place helps ensure that risks are properly identified and addressed, and enables organizations to make informed and effective decisions about risk. Risk reporting procedures, an audit committee consisting of mid-level management, and well-defined and approved controls are all important components of an effective risk management program, but established risk domains are the most important for effective risk decision making.

Key performance indicators (KPIs) are the best tool to monitor the effectiveness of information security governance because they are quantifiable and measurable metrics that reflect the achievement of the information security objectives and the alignment of the information security strategy with the business goals. KPIs can help to evaluate the performance, efficiency, quality, and value of the information security processes and activities, and to identify the areas of improvement or adjustment. KPIs can also provide feedback to the management and the stakeholders on the status and progress of the information security governance.Some examples of KPIs for information security governance are: percentage of compliance with security policies and standards, number and severity of security incidents, return on security investment, and maturity level of information security capabilities12.

A balanced scorecard is a strategic management tool that translates the vision and mission of the organization into four perspectives: financial, customer, internal process, and learning and growth. A balanced scorecard can help to align the information security strategy with the business strategy, but it is not a tool to monitor the effectiveness of information security governance.A balanced scorecard can include KPIs as part of its measurement system, but it is not a substitute for KPIs13.

A business impact analysis (BIA) is a process of assessing the potential consequences of a disruption to the organization's critical business functions or processes. A BIA can help to identify the critical assets, dependencies, recovery priorities, and recovery objectives for the information security program, but it is not a tool to monitor the effectiveness of information security governance.A BIA is a one-time or periodic activity, not a continuous monitoring process14.

A risk profile is a representation of the organization's exposure to various types of risks, such as operational, financial, strategic, or reputational. A risk profile can help to identify the sources, likelihood, and impact of potential threats to the organization's assets and objectives, and to determine the risk appetite and tolerance for the information security program, but it is not a tool to monitor the effectiveness of information security governance.A risk profile is a snapshot of the organization's risk posture at a given point in time, not a dynamic monitoring tool15.Reference= CISM Review Manual, 16th Edition, pages 23-241; CISM Exam Content Outline, Domain 1, Knowledge Statement 1.122; CISM Review Questions, Answers & Explanations Database, Question ID 10093; CISM Review Questions, Answers & Explanations Database, Question ID 10104; CISM Review Questions, Answers & Explanations Database, Question ID 10115

Inherent risk is the risk that exists before any controls are applied. It is influenced by factors such as the nature, value, sensitivity, and exposure of the information asset. Business criticality is one of the most important factors that affect the inherent risk of an information asset, as it reflects how essential the asset is for the organization's operations and objectives. The higher the business criticality, the higher the inherent risk.Risk tolerance, NPV, and ROI are not directly related to the inherent risk of an information asset, as they are more relevant for the risk assessment and risk treatment processes.Reference= CISM Review Manual, 16th Edition, page 971 Business criticality is the degree to which an asset is essential to the success of the business and the extent to which its loss or compromise could have a significant impact on the business. Business criticality is one of the main factors that help to determine the inherent risk of an asset, as assets that are more critical to the business tend to have a higher inherent risk.

A disaster recovery plan (DRP) test is a simulation of a disaster scenario to evaluate the effectiveness and readiness of the DRP. The greatest inherent risk when performing a DRP test is the disruption to the production environment, which could cause operational issues, data loss, or system damage. Therefore, it is essential to plan and execute the DRP test carefully, with proper backup, isolation, and rollback procedures. Poor documentation, lack of communication, and lack of coordination are also potential risks, but they are not as severe as disrupting the production environment.Reference= CISM Review Manual 15th Edition, page 253; CISM Review Questions, Answers & Explanations Database - 12 Month Subscription, QID 224.

The greatest inherent risk when performing a disaster recovery plan (DRP) test is disruption to the production environment. A DRP test involves simulating a disaster scenario to ensure that the organization's plans are effective and that it is able to recover from an incident. However, this involves running tests on the production environment, which has the potential to disrupt the normal operations of the organization. This inherent risk can be mitigated by running tests on a non-production environment or by running tests at times when disruption will be minimized.
