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. References = 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.

During the initiation phase of the system development life cycle (SDLC) for a software project, information security activities should address security objectives, which are derived from the business objectives and the risk assessment. Security objectives define the desired level of protection for the system and its data, and guide the selection of security controls in later phases. Baseline security controls are predefined sets of security requirements that apply to common types of systems or environments. Benchmarking security metrics is a process of comparing the performance of security processes or controls against a standard or best practice. Cost-benefit analyses are used to evaluate the feasibility and effectiveness of security controls, and are usually performed in the acquisition/development phase or the implementation phase of the SDLC. References = CISM Review Manual, 16th Edition, page 1021; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 772

= Information classification is the process of assigning appropriate labels to information assets based on their sensitivity and value to the organization. Information classification should be aligned with the business objectives and risk appetite of the organization, and should be reviewed periodically to ensure its accuracy and relevance. The information security manager is responsible for establishing and maintaining the information classification policy and procedures, as well as providing guidance and oversight to the data owners and custodians. Data owners are the individuals who have the authority and accountability for the information assets within their business unit or function. Data owners are responsible for determining the appropriate classification level and security controls for their information assets, as well as ensuring compliance with the information classification policy and procedures. Data custodians are the individuals who have the operational responsibility for implementing and maintaining the security controls for the information assets assigned to them by the data owners.

If the information security manager believes that information has been classified inappropriately, increasing the risk of a breach, the best action is to complete a risk assessment and refer the results to the data owners. A risk assessment is a systematic process of identifying, analyzing, and evaluating the risks associated with the information assets, and recommending appropriate risk treatment options. By conducting a risk assessment, the information security manager can provide objective and evidence-based information to the data owners, highlighting the potential impact and likelihood of a breach, as well as the cost and benefit of implementing additional security controls. This will enable the data owners to make informed decisions about the appropriate classification level and security controls for their information assets, and to justify and document any deviations from the information classification policy and procedures.

The other options are not the best actions for the information security manager. Refering the issue to internal audit for a recommendation is not the best action, because internal audit is an independent and objective assurance function that provides assurance on the effectiveness of governance, risk management, and control processes. Internal audit is not responsible for providing recommendations on information classification, which is a management responsibility. Re-classifying the data and increasing the security level to meet business risk is not the best action, because the information security manager does not have the authority or accountability for the information assets, and may not have the full understanding of the business context and objectives of the data owners. Instructing the relevant system owners to reclassify the data is not the best action, because system owners are not the same as data owners, and may not have the authority or accountability for the information assets either. System owners are the individuals who have the authority and accountability for the information systems that process, store, or transmit the information assets. System owners are responsible for ensuring that the information systems comply with the security requirements and controls defined by the data owners and the information security manager. References = CISM Review Manual, 16th Edition, ISACA, 2020, pp. 49-51, 63-64, 69-701; CISM Online Review Course, Domain 3: Information Security Program Development and Management, Module 2: Information Security Program Framework, ISACA2

 Performing a risk assessment is the best approach to determine how to protect newly acquired data assets prior to integration, as it will help to identify the threats, vulnerabilities, impacts, and likelihoods of the data assets, and to prioritize the appropriate risk treatment options. Including security requirements in the contract is a good practice, but it may not be sufficient to address the specific risks of the data assets. Assessing security controls and reviewing data architecture are also important steps, but they should be done after performing a risk assessment, as they will depend on the risk level and the risk app

The best approach to determine how to protect newly acquired data assets prior to integration is to perform a risk assessment. A risk assessment will identify the various threats and vulnerabilities associated with the data assets and help the organization develop an appropriate security strategy. This risk assessment should include an assessment of the security controls in place to protect the data, a review of the data architecture, and a review of any contractual requirements related to security.
