CISM Exam Dumps - Isaca Certification Questions and Answers

An advanced persistent threat (APT) is a stealthy and sophisticated attack that aims to compromise and maintain access to a target network or system over a long period of time, often for espionage or sabotage purposes. APTs are difficult to detect by conventional security tools, such as antivirus or firewalls, that rely on signatures or rules to identify threats. Therefore, the best way to monitor for APTs is to search for anomalies in the environment, such as unusual network traffic, user behavior, file activity, or system configuration changes, that may indicate a compromise or an ongoing attack.

Determining the root cause of the incident is essential for preventing or minimizing the recurrence of similar incidents, as well as for identifying and implementing corrective actions to improve the security posture of the organization.

An increase in false negatives would be of greatest concern when reviewing the performance of an organization’s IDSs, because it means that the IDSs are failing to detect and alert on actual attacks that are occurring on the network. False negatives can lead to serious security breaches, data loss, reputational damage, and legal liabilities for the organization. False positives, on the other hand, are alerts that are triggered by benign or normal activities that are mistaken for attacks. False positives can cause annoyance, inefficiency, and desensitization, but they do not pose a direct threat to the security of the network. Therefore, a decrease in false positives would be desirable, and an increase in false positives would be less concerning than an increase in false negatives.

Compartmentalization is the best defense-in-depth implementation for protecting high value assets or for handling environments that have trust concerns because it is a strategy that divides the network or system into smaller segments or compartments, each with its own security policies, controls, and access rules. Compartmentalization helps to isolate and protect the most sensitive or critical data and functions from unauthorized or malicious access, as well as to limit the damage or impact of a breach or compromise. Compartmentalization also helps to enforce the principle of least privilege, which grants users or processes only the minimum access rights they need to perform their tasks. Therefore, compartmentalization is the correct answer.

 Metrics for an information security program should be aligned with the security objectives and strategy, and should demonstrate how well the program is performing in terms of reducing risk, enhancing security posture, and supporting business goals. Metrics that support major information security initiatives, reflect the corporate risk culture, or reduce information security program spending may be useful, but they are not the best approach for establishing metrics for the entire program.

The best approach to developing an incident escalation process is to classify incidents based on the information assets affected, because this will help to determine the impact and severity of the incidents, as well as the appropriate response and recovery actions. The information assets affected by an incident can indicate the potential loss of confidentiality, integrity, or availability of the information, as well as the legal, regulatory, contractual, or reputational implications. By classifying incidents based on the information assets affected, the organization can prioritize the incidents and escalate them to the relevant stakeholders and authorities.

The most important consideration when developing key performance indicators (KPIs) for the information security program is B. Alignment with business initiatives. This is because KPIs are measurable values that demonstrate how effectively the information security program is achieving its objectives and delivering value to the organization. KPIs should be aligned with the business initiatives, such as the strategic goals, the mission, the vision, and the values of the organization, and support the achievement of the desired outcomes and benefits. KPIs should also reflect the needs, expectations, and challenges of the business stakeholders, and provide relevant, meaningful, and actionable information for decision making and improvement. KPIs should not be too technical, complex, or ambiguous, but rather focus on the key aspects of information security performance, such as risk, compliance, maturity, value, and effectiveness.

KPIs are measurable values that demonstrate how effectively the information security program is achieving its objectives and delivering value to the organization. KPIs should be aligned with the business initiatives, such as the strategic goals, the mission, the vision, and the values of the organization, and support the achievement of the desired outcomes and benefits.

Declaring an incident is the best course of action when confidential information is inadvertently disseminated outside the organization, as it triggers the incident response process, which aims to contain, analyze, eradicate, recover, and learn from the incident. Declaring an incident also helps to communicate the exposure to the relevant stakeholders, such as senior management, legal authorities, customers, or regulators, and to comply with the applicable laws and regulations regarding notification and disclosure. Changing the encryption keys, reviewing compliance requirements, or communicating the exposure are possible steps within the incident response process, but they are not the first course of action.

Conducting periodic user awareness training is the best way to mitigate accidental data loss events because it can educate the users on the causes, consequences, and prevention of data loss, and increase their awareness of the security policies and procedures of the organization. User awareness training can also help users to identify and report potential data loss incidents, and to adopt good practices such as backing up data, encrypting data, and using secure channels for data transmission and storage.

References: The article Mistakes Happen—Mitigating Unintentional Data Loss from the ISACA Journal 2018 states that “user awareness training is the most effective way to prevent unintentional data loss” and that “user awareness training should include information on the types and sources of data loss, the impact and cost of data loss, the legal and regulatory requirements for data protection, the organization’s data security policies and procedures, the roles and responsibilities of users in data security, the best practices and tools for data security, and the reporting and escalation process for data loss incidents” (p. 2)1. The Data Spill Management Guide from the Cyber.gov.au website also states that “user awareness training is an important preventative measure to reduce the likelihood of data spills” and that “user awareness training should cover topics such as data classification, data handling, data storage, data transmission, data disposal, and data spill reporting” (p. 2)

 When developing a categorization method for security incidents, the categories must have agreed-upon definitions. This means that the categories should be clear, consistent, and understandable for all the parties involved in the incident response process, such as the incident handlers, the stakeholders, the management, and the external authorities. Having agreed-upon definitions for the categories can help to ensure that the incidents are classified and reported accurately, that the appropriate actions and resources are allocated, and that the communication and coordination are effective. Aligning with industry standards, creating by the incident handler, and aligning with reporting requirements are not mandatory for developing a categorization method for security incidents, although they may be desirable or beneficial depending on the context and objectives of the organization. Aligning with industry standards can help to adopt best practices and benchmarks for incident response, but it may not be feasible or suitable for all types of incidents or organizations. Creating by the incident handler can allow for flexibility and customization of the categories, but it may also introduce inconsistency and ambiguity if the definitions are not shared or agreed upon by others. Aligning with reporting requirements can help to comply with legal or contractual obligations, but it may not cover all the aspects or dimensions of the incidents that need to be categorized. References = CISM Review Manual, 16th Edition, pages 200-2011; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 822

When developing a categorization method for security incidents, the categories MUST have agreed-upon definitions. This is because having clear and consistent definitions for each category of incidents will help to ensure a common understanding and communication among the incident response team and other stakeholders. It will also facilitate the accurate and timely identification, classification, reporting and analysis of incidents. Having agreed-upon definitions will also help to avoid confusion, ambiguity and inconsistency in the incident management process

Organizational units contribute to and agree on priorities is the best way to facilitate effective strategic alignment of security initiatives because it ensures that the security initiatives are aligned with the business goals and objectives, supported by relevant stakeholders, and prioritized based on risk and value. The business strategy is periodically updated is not sufficient to facilitate effective strategic alignment of security initiatives because it does not involve collaboration or communication between different organizational units. Procedures and standards are approved by department heads is not sufficient to facilitate effective strategic alignment of security initiatives because it does not reflect the strategic direction or vision of the organization. Periodic security audits are conducted by a third-party is not sufficient to facilitate effective strategic alignment of security initiatives because it does not address the planning or implementation of security initiatives.

According to the NIST SP 800-61 Computer Security Incident Handling Guide, the type of confirmed incident is one of the most important criteria for choosing a containment strategy, as different types of incidents may require different levels of urgency, scope, and impact1. For example, a denial-of-service attack may require a different containment strategy than a ransomware attack or a data breach.

 A risk register is a document that records and tracks the information security risks facing an organization, such as their sources, impacts, likelihoods, responses, and statuses. A risk register provides the most comprehensive insight into ongoing threats facing an organization, as it covers both internal and external threats, as well as their current and potential effects on the organization’s assets, processes, and objectives. A risk register also helps to prioritize and monitor the risk mitigation actions and controls, and to communicate the risk information to relevant stakeholders. Therefore, option B is the most appropriate answer.

Option A is not the best answer because a business impact analysis (BIA) is a process that identifies and evaluates the critical business functions, assets, and dependencies of an organization, and assesses their potential impact in the event of a disruption or loss. A BIA does not provide a comprehensive insight into ongoing threats facing an organization, as it focuses more on the consequences of the threats, rather than their sources, likelihoods, or responses. A BIA is mainly used to support the business continuity and disaster recovery planning, rather than the information security risk management.

Option C is not the best answer because penetration testing is a method of simulating a malicious attack on an organization’s IT systems or networks, to evaluate their security posture and identify any vulnerabilities or weaknesses that could be exploited by real attackers. Penetration testing does not provide a comprehensive insight into ongoing threats facing an organization, as it only covers a specific scope, target, and scenario, rather than the whole range of threats, sources, and impacts. Penetration testing is mainly used to validate and improve the technical security controls, rather than the information security risk management.

Option D is not the best answer because vulnerability assessment is a process of scanning and analyzing an organization’s IT systems or networks, to detect and report any flaws or gaps that could pose a security risk. Vulnerability assessment does not provide a comprehensive insight into ongoing threats facing an organization, as it only covers the technical aspects of the threats, rather than their business, legal, or regulatory implications. Vulnerability assessment is mainly used to identify and remediate the security weaknesses, rather than the information security risk management. References = CISM Review Manual 15th Edition1, pages 258-259; CISM Review Questions, Answers & Explanations Database - 12 Month Subscription, QID 306.

A risk register provides the MOST comprehensive insight into ongoing threats facing an organization. This is because a risk register is a document that records and tracks the identified risks, their likelihood, impact, mitigation strategies, and status. A risk register helps an organization to monitor and manage the threats that could affect its objectives, assets, and operations. A risk register also helps an organization to prioritize its response efforts and allocate its resources accordingly.

The most appropriate information to communicate to senior management regarding information risk is the risk profile changes, which reflect the current level and nature of the risks that the organization faces. The risk profile changes can help senior management to understand the impact of the risks on the business objectives, the effectiveness of the risk management strategy, and the need for any adjustments or improvements. The risk profile changes can also help senior management to prioritize the allocation of resources and to make informed decisions.
