Top Tips for Passing the Isaca CISM Exam on Your First Try

= Business continuity management (BCM) is the process of planning and implementing measures to ensure the continuity of critical business processes in the event of a disruption. The most important consideration of BCM is ensuring human safety, as this is the primary responsibility of any organization and the basis of ethical conduct. Human safety includes protecting the health and well-being of employees, customers, suppliers, and other stakeholders who may be affected by a disruption. Identifying critical business processes, ensuring the reliability of backup data, and securing critical information assets are also important aspects of BCM, but they are secondary to human safety. References = CISM Review Manual, 16th Edition, ISACA, 2020, p. 2111; CISM Online Review Course, Domain 4: Information Security Incident Management, Module 4: Business Continuity and Disaster Recovery, ISACA2

 Wiping the device remotely is the best option to minimize the risk of data exposure from a stolen personal mobile device. This action will erase all the data stored on the device, including the sensitive corporate data, and prevent unauthorized access or misuse. Wiping the device remotely can be done using enterprise mobility management (EMM) or mobile device management (MDM) tools that allow administrators to remotely manage and secure mobile devices. Alternatively, some mobile devices have built-in features that allow users to wipe their own devices remotely using another device or a web portal.

Preventing the user from using personal mobile devices is not a feasible option, as it may affect the user’s productivity and convenience. Moreover, this option does not address the immediate risk of data exposure from the stolen device.

Reporting the incident to the police is a good practice, but it does not guarantee that the device will be recovered or that the data will be protected. The police may not have the resources or the authority to track down the device or access it.

Removing the user’s access to corporate data is a preventive measure that can limit the damage caused by a stolen device, but it does not eliminate the risk of data exposure from the data already stored on the device. The user may have cached or downloaded data that can still be accessed by an attacker even if the user’s access is revoked. References =

= The best approach for developing a physical access control policy for the organization is to conduct a risk assessment to determine the security risks and mitigating controls that are relevant and appropriate for the organization’s data center. A risk assessment is a process of identifying, analyzing, and evaluating the information security risks that could affect the availability, integrity, or confidentiality of the servers, applications, and data that are hosted in the data center. A risk assessment can help to determine the likelihood and impact of the unauthorized or inappropriate physical access to the data center, such as theft, damage, sabotage, or espionage, and the potential consequences for the organization and its customers, such as service disruption, data loss, data breach, or legal liability. A risk assessment can also help to identify and prioritize the appropriate risk treatment options, such as implementing technical, administrative, or physical controls to prevent, detect, or respond to the physical access incidents, such as locks, alarms, cameras, guards, badges, or logs. A risk assessment can also help to communicate and report the risk level and status to the senior management and the relevant stakeholders, and to provide feedback and recommendations for improvement and optimization of the physical access control policy and the risk management process.

Reviewing customers’ security policies, developing access control requirements for each system and application, and designing single sign-on (SSO) or federated access are all possible steps that the organization can take after conducting the risk assessment, but they are not the best ones. Reviewing customers’ security policies is a process of understanding and complying with the customers’ expectations and requirements for the security of their servers, applications, and data that are hosted in the data center, and ensuring that the organization’s physical access control policy is consistent and compatible with them. Developing access control requirements for each system and application is a process of defining and implementing the specific rules and criteria for granting or denying the physical access to the servers and applications that are hosted in the data center, based on the roles, responsibilities, and privileges of the users, and the sensitivity and criticality of the systems and applications. Designing single sign-on (SSO) or federated access is a process of enabling and facilitating the authentication and authorization of the users who need to access the servers and applications that are hosted in the data center, by using a single or shared identity and credential across multiple systems and domains. References = CISM Review Manual 15th Edition, pages 51-531; CISM Practice Quiz, question 1542

The most effective way to avoid paying the ransom in a ransomware attack is to have a properly tested offline backup system. A ransomware attack is a type of cyberattack that encrypts the victim’s data or systems and demands a payment for the decryption key. A properly tested offline backup system is a method of storing copies of the data or systems in a separate location that is not connected to the network or the internet. By having a properly tested offline backup system, the hospital can restore its critical server from the backup without paying the ransom or losing any data. The other options are not the most effective way to avoid paying the ransom in a ransomware attack, although they may be some preventive or detective measures. Employee training on ransomware is a preventive measure that can help raise awareness and reduce the likelihood of falling victim to phishing or other social engineering techniques that may deliver ransomware. However, it does not guarantee that employees will always follow best practices or that ransomware will not enter the network through other means. A continual server replication process is a method of creating copies of the server data or systems in real time or near real time. However, it may not be effective against ransomware, as the replication process may also copy the encrypted data or systems, making them unusable. A properly configured firewall is a preventive measure that can help block malicious network traffic and prevent unauthorized access to the server. However, it does not guarantee that ransomware will not bypass the firewall through other channels, such as email attachments or removable media.

Reviewing the vendor contract should be the information security manager’s first course of action when discovering an HVAC vendor has remote access to the stores to enable real-time monitoring and equipment diagnostics. The vendor contract should specify the terms and conditions of the vendor’s access to the retailer’s network, such as the scope, purpose, duration, frequency, and method of access. The vendor contract should also define the roles and responsibilities of both parties regarding security, privacy, compliance, liability, and incident response. Reviewing the vendor contract will help the information security manager to understand the contractual obligations and expectations of both parties, and to identify any gaps or issues that need to be addressed or resolved1. The other options are not the first course of action for the information security manager when discovering an HVAC vendor has remote access to the stores. Conducting a penetration test of the vendor may be a useful way to assess the vendor’s security posture and potential vulnerabilities, but it should be done with the vendor’s consent and cooperation, and after reviewing the vendor contract2. Reviewing the vendor’s technical security controls may be a necessary step to verify the vendor’s compliance with security standards and best practices, but it should be done after reviewing the vendor contract and in accordance with the agreed-upon audit procedures3. Disconnecting the real-time access may be a drastic measure that could disrupt the vendor’s service delivery and violate the vendor contract, unless there is a clear and imminent threat or breach that warrants such action.

Chain of custody is the MOST important requirement when collecting admissible evidence, because it ensures the integrity and authenticity of the evidence by documenting its history, handling, and storage. Chain of custody records who, what, when, where, why, and how the evidence was collected, analyzed, and preserved. Without a proper chain of custody, the evidence may be challenged or rejected in a court of law. Need to know, preserving audit logs, and due diligence are important aspects of evidence collection, but they are not as critical as chain of custody. References = CISM Review Manual, 16th Edition, page 3031; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 1492The most important requirement when collecting admissible evidence is the chain of custody. The chain of custody is a documented record of who had control of the evidence at any given time, from the point of collection until the evidence is presented in court. This is important in order to ensure the evidence can be authenticated and is not subject to tampering or any other form of interference. Other important considerations include need to know, preserving audit logs, and due diligence.

Digital encryption is the process of transforming data into an unreadable form using a secret key or algorithm. Digital encryption will ensure the confidentiality of content when accessing an email system over the Internet, as it prevents unauthorized parties from intercepting, viewing, or modifying the email messages. Digital encryption can be applied to both the email content and the email transmission, using different methods such as symmetric encryption, asymmetric encryption, or hybrid encryption. Digital encryption can also provide other benefits such as authentication, integrity, and non-repudiation, depending on the encryption scheme and the use of digital signatures or certificates. References = CISM Review Manual 15th Edition, page 101, page 102.

 The best way to ensure the capability to restore clean data after a ransomware attack is to maintain multiple offline backups. Offline backups are backups that are not connected to the network or the internet, and therefore are not accessible by ransomware. Multiple offline backups provide redundancy and allow the organization to choose the most recent and uncorrupted backup to restore the data. Offline backups should be stored in a secure location and tested regularly to ensure their integrity and availability.

Purchasing cyber insurance may help the organization cover some of the costs associated with a ransomware attack, such as ransom payment, data recovery, legal fees, etc., but it does not guarantee the capability to restore clean data. Cyber insurance policies may have exclusions, limitations, or conditions that affect the coverage and reimbursement. Moreover, cyber insurance does not prevent or mitigate the ransomware attack itself, and it may not cover all the losses or damages caused by the attack.

Encrypting sensitive production data may protect the confidentiality of the data from unauthorized access or disclosure, but it does not prevent ransomware from encrypting the data again. Ransomware does not need to decrypt the data to encrypt it, and it may use a different encryption algorithm or key than the one used by the organization. Encrypting production data may also increase the complexity and time required for data recovery, especially if the encryption keys are lost or compromised.

Performing integrity checks on backups may help the organization verify that the backups are not corrupted or tampered with, but it does not ensure the capability to restore clean data after a ransomware attack. Integrity checks are a preventive measure that should be done before the attack, not after. If the backups are already infected or encrypted by ransomware, performing integrity checks will not help to recover the data. Integrity checks should be complemented by other measures, such as isolation, versioning, and offline storage, to protect the backups from ransomware. References = CISM Certified Information Security Manager Study Guide, Chapter 9: Business Continuity and Disaster Recovery, page 3081; CISM Foundations: Module 4 Course, Part Two: Business Continuity and Disaster Recovery Plans2; Ransomware recovery: 8 steps to successfully restore from backup3; Ransomware Recovery: 5 Steps to Recover Data4

Communicating the residual risk is the best way to facilitate an information security manager’s efforts to obtain senior management commitment for an information security program. The residual risk is the level of risk that remains after applying the security controls and mitigation measures. The residual risk reflects the effectiveness and efficiency of the information security program, as well as the potential impact and exposure of the organization. The information security manager should communicate the residual risk to the senior management in a clear, concise, and relevant manner, using quantitative or qualitative methods, such as risk matrices, heat maps, dashboards, or reports. The communication of the residual risk should also include the comparison with the inherent risk, which is the level of risk before applying any security controls, and the risk appetite, which is the level of risk that the organization is willing to accept. The communication of the residual risk should help the senior management to understand the value and performance of the information security program, as well as the need and justification for further investment or improvement. Presenting evidence of inherent risk, reporting the security maturity level, and presenting compliance requirements are all important aspects of the information security program, but they are not the best ways to obtain senior management commitment. These aspects may not directly demonstrate the benefits or outcomes of the information security program, or they may not align with the business objectives or priorities of the organization. For example, presenting evidence of inherent risk may show the potential threats and vulnerabilities that the organization faces, but it may not indicate how the information security program addresses or reduces them. Reporting the security maturity level may show the progress and status of the information security program, but it may not relate to the risk level or the business impact. Presenting compliance requirements may show the legal or regulatory obligations that the organization must fulfill, but it may not reflect the actual security needs or goals of the organization. Therefore, communicating the residual risk is the best way to obtain senior management commitment for an information security program, as it shows the results and value of the information security program for the organization. References = CISM Review Manual 2023, page 41 1; CISM Practice Quiz 2

The level of protection for an information asset should be based on the impact to the business function that depends on the asset. The impact to the business function reflects the value and criticality of the information asset to the organization, and the potential consequences of its loss, compromise, or unavailability. The impact to the business function can be measured in terms of financial, operational, reputational, legal, or strategic effects. The higher the impact, the higher the level of protection required.

Impact on information security program, cost of controls, and cost to replace are not the best factors to provide guidance when deciding the level of protection for an information asset. Impact on information security program is a secondary effect that depends on the impact to the business function. Cost of controls and cost to replace are important considerations for implementing and maintaining the protection, but they do not determine the level of protection needed. Cost of controls and cost to replace should be balanced with the impact to the business function and the risk appetite of the organization. References = CISM Certified Information Security Manager Study Guide, Chapter 2: Information Risk Management, page 671; CISM Foundations: Module 2 Course, Part One: Information Risk Management2; CISM Review Manual 15th Edition, Chapter 2: Information Risk Management, page 693

When deciding the level of protection for an information asset, the most important factor to consider is the impact to the business function. The value of the asset should be evaluated in terms of its importance to the organization's operations and how its security posture affects the organization's overall security posture. Additionally, the cost of implementing controls, the potential impact on the information security program, and the cost to replace the asset should be taken into account when determining the appropriate level of protection for the asset.

The primary objective of performing a vulnerability assessment following a business system update is to review the effectiveness of controls. A vulnerability assessment is a systematic review of security weaknesses in an information system. It evaluates if the system is susceptible to any known vulnerabilities, assigns severity levels to those vulnerabilities, and recommends remediation or mitigation, if and whenever needed1. A business system update is a process of modifying or enhancing an information system to improve its functionality, performance, security, or compatibility. A business system update may introduce new features, fix bugs, patch vulnerabilities, or comply with new standards or regulations2. Performing a vulnerability assessment following a business system update is important because it helps to:

•Review the effectiveness of controls that are implemented to protect the information sys-tem from threats and risks

•Identify any new or residual vulnerabilities that may have been introduced or exposed by the update

•Evaluate the impact and likelihood of potential incidents that may exploit the vulnerabili-ties

•Prioritize and implement appropriate actions to address the vulnerabilities

•Verify and validate the security posture and compliance of the updated information sys-tem

Therefore, the primary objective of performing a vulnerability assessment following a business system update is to review the effectiveness of controls that are designed to ensure the confidentiality, integrity, and availability of the information system and its data. The other options are not the primary objectives of performing a vulnerability as-sessment following a business system update. Determining operational losses is not an objective, but rather a possible consequence of not performing a vulnerability as-sessment or not addressing the identified vulnerabilities. Improving the change control process is not an objective, but rather a possible outcome of performing a vulnerability assessment and incorporating its results and recommendations into the change man-agement cycle. Updating the threat landscape is not an objective, but rather a prereq-uisite for performing a vulnerability assessment that requires using up-to-date sources of threat intelligence and vulnerability information.

The PRIMARY benefit to an organization when information security program requirements are aligned with employment and staffing processes is that access is granted based on task requirements. This means that the organization can ensure that the employees have the appropriate level and scope of access to the information assets and systems that they need to perform their duties, and that the access is granted, reviewed, and revoked in accordance with the security policies and standards. This can help to reduce the risk of unauthorized access, misuse, or leakage of information, as well as to comply with the principle of least privilege and the segregation of duties12. Security incident reporting procedures are followed (A) is a benefit to an organization when information security program requirements are aligned with employment and staffing processes, but it is not the PRIMARY benefit. Security incident reporting procedures are the steps and guidelines that the employees should follow when they detect, report, or respond to a security incident. Aligning the information security program requirements with the employment and staffing processes can help to ensure that the employees are aware of and trained on the security incident reporting procedures, and that they are enforced and monitored by the management. This can help to improve the effectiveness and efficiency of the incident response process, as well as to comply with the legal and contractual obligations12. Security staff turnover is reduced (B) is a benefit to an organization when information security program requirements are aligned with employment and staffing processes, but it is not the PRIMARY benefit. Security staff turnover is the rate at which the security personnel leave or join the organization. Aligning the information security program requirements with the employment and staffing processes can help to reduce the security staff turnover by ensuring that the security roles and responsibilities are clearly defined and communicated, that the security personnel are adequately compensated and motivated, and that the security personnel are evaluated and developed regularly. This can help to retain the security talent and expertise, as well as to reduce the costs and risks associated with the security staff turnover12. Information assets are classified appropriately © is a benefit to an organization when information security program requirements are aligned with employment and staffing processes, but it is not the PRIMARY benefit. Information asset classification is the process of assigning a security level or category to the information assets based on their value, sensitivity, and criticality to the organization. Aligning the information security program requirements with the employment and staffing processes can help to ensure that the information assets are classified appropriately by establishing the ownership and custody of the information assets, the criteria and methods for the information asset classification, and the roles and responsibilities for the information asset classification. This can help to protect the information assets according to their security level or category, as well as to comply with the regulatory and contractual requirements12. References = 1: CISM Review Manual 15th Edition, page 75-76, 81-82, 88-89, 93-941; 2: CISM Domain 1: Information Security Governance (ISG) [2022 update]2

An anomaly-based intrusion detection system (IDS) operates by gathering data on normal network behavior and using it as a baseline for measuring abnormal activity. This is important because it allows the IDS to detect any activity that is outside of the normal range of usage for the network, which can help to identify potential malicious activity or security threats. Additionally, the IDS will monitor for any changes in the baseline behavior and alert the administrator if any irregularities are detected. By contrast, signature-based IDSs operate by gathering attack pattern signatures from historical data and comparing them against incoming traffic in order to identify malicious activity.

 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.
