Which of the following BEST enables the capability of an organization to sustain the delivery of products and services within acceptable time frames and at predefined capacity during a disruption?
Correct Answer:
B
The best option to enable the capability of an organization to sustain the delivery of products and services within acceptable time frames and at predefined capacity during a disruption is B. Business continuity plan (BCP). This is because a BCP is a documented collection of procedures and information that guides the organization to prepare for, respond to, and recover from a disruption, such as a natural disaster, a cyberattack, or a pandemic. A BCP aims to ensure the continuity of the critical business functions and processes that support the delivery of products and services to the customers and stakeholders. A BCP also defines the roles, responsibilities, resources, and actions required to maintain the operational resilience of the organization in the face of a disruption.

Which of the following functions is MOST critical when initiating the removal of system access for terminated employees?
Correct Answer:
B
Information security is the most critical function when initiating the removal of system access for terminated employees, as it is responsible for ensuring that the access rights of the employees are revoked in a timely and effective manner, and that the security of the organization’s data and systems is maintained. Information security should coordinate with other functions, such as HR, legal, and help desk, to implement the access removal process, but it is the primary function that has the authority and capability to disable or delete the access credentials of the terminated employees. The other options are not as critical as information security, as they may have different roles or responsibilities in the access removal process, or they may not have direct access to the systems or tools that control the access rights of the employees.

CISM Review Manual 15th Edition, page 114: “Information security is responsible for ensuring that access rights are revoked in a timely and effective manner.”
SOC 2 Controls: Access Removal for Terminated or Transferred Users, snippets: “Systems access that is no longer required for terminated or transferred users is removed within one business day. For terminated employees, access to key IT systems is revoked in a timely manner. A termination checklist and ticket are completed, and access is revoked for employees as a component of the employee termination process.”
IT Involvement in Employee Termination, A Checklist, snippets: “Disable all network access. If your company uses a master access list of active passwords, tell the system to deny any passcodes associated with the user being terminated. If your system doesn’t have a deny function, delete the user and their associated passwords. Monitor employee access.”
Human resources (HR) is the most critical function when initiating the removal of system access for terminated employees because it is responsible for notifying the relevant parties, such as information security, help desk, and legal, of the employee’s termination status and date. HR also ensures that the employee’s exit process is completed and documented, and that the employee returns any company-owned devices or assets. HR also coordinates with the employee’s manager and team to ensure a smooth transition of work and responsibilities.

During which of the following development phases is it MOST challenging to implement security controls?
Correct Answer:
C
The development phase is the stage of the system development life cycle (SDLC) where the system requirements, design, architecture, and implementation are performed. The development phase is most challenging to implement security controls because it involves complex and dynamic processes that may not be well understood or documented. Security controls are essential for ensuring the confidentiality, integrity, and availability of the system and its data, as well as for complying with regulatory and contractual obligations. However, security controls may also introduce additional costs, risks, and constraints to the development process, such as:
✑ Increased complexity and overhead of testing, verification, validation, and maintenance
✑ Reduced flexibility and agility of changing requirements or design
✑ Increased dependency on external vendors or third parties for security services or products
✑ Increased vulnerability to errors, defects, or vulnerabilities in the code or configuration
✑ Increased difficulty in measuring and reporting on security performance or effectiveness
Therefore, implementing security controls in the development phase requires careful planning, coordination, communication, and collaboration among all stakeholders involved in the SDLC. It also requires a clear understanding of the security objectives, scope, criteria, standards, policies, procedures, roles, responsibilities, and resources for the system. Moreover, it requires a proactive approach to identifying and mitigating potential threats or risks that may affect the security of the system.

Which of the following components of an information security risk assessment is MOST valuable to senior management?
Correct Answer:
B
Residual risk is the risk that remains after implementing risk mitigation actions. It is the most valuable component for senior management because it helps them to evaluate the effectiveness and efficiency of risk management and make informed decisions about risk acceptance, transfer or avoidance.

An information security manager has been notified about a compromised endpoint device Which of the following is the BEST course of action to prevent further damage?
Correct Answer:
B
A compromised endpoint device is a potential threat to the security of the network and the data stored on it. The best course of action to prevent further damage is to isolate the endpoint device from the network and other devices, so that the attacker cannot access or spread to other systems. Isolating the endpoint device also allows the information security manager to investigate the incident and determine the root cause, the extent of the compromise, and the appropriate remediation steps. Wiping and resetting the endpoint device may not be feasible or desirable, as it may result in data loss or evidence destruction. Powering off the endpoint device may not stop the attack, as the attacker may have installed persistent malware or backdoors that can resume once the device is powered on again. Running a virus scan on the endpoint device may not be effective, as the attacker may have used sophisticated techniques to evade detection or disable the antivirus software.

The best way to reduce the risk associated with a bring your own device (BYOD) program is to implement a mobile device policy and standard. This policy should include guidelines and rules regarding the use of mobile devices, such as acceptable use guidelines and restrictions on the types of data that can be stored or accessed on the device. Additionally, it should also include requirements for secure mobile device practices, such as the use of strong passwords, encryption, and regular patching. A mobile device management (MDM) solution can also be implemented to help ensure mobile devices meet the organizational security requirements. However, it is not enough to simply implement the policy and MDM solution; employees must also be trained on the secure mobile device practices to ensure the policy is followed.
