CISM Exam Dumps - Certified Information Security Manager

The BEST indication that an organization has a mature information security culture is when its staff consistently consider risk in making decisions. When an organization's staff understands the risks associated with their actions and are empowered to make risk-informed decisions, it indicates that the organization has a mature information security culture.

According to the Certified Information Security Manager (CISM) Study Manual, "A mature information security culture exists when the people within the organization understand and appreciate the risks associated with information and technology and when they take steps to manage those risks on a daily basis."

While information security training, documented information security policies, and regular interaction between the chief information security officer (CISO) and the board are all important components of a mature information security culture, they are not sufficient on their own. It is only when staff consistently consider risk in making decisions that an organization's information security culture can be considered mature.

During due diligence, performing a risk assessment is critical to understanding the potential impact of integrating the new organization into the acquiring company. This includes evaluating inherited risks, compliance gaps, and technical vulnerabilities.

“As part of due diligence during mergers and acquisitions, it is crucial to assess risks associated with the target organization to ensure proper integration and continuity.”

— CISM Review Manual 15th Edition, Chapter 2: Risk Management, Section: Due Diligence

ISACA’s CISM practice database reinforces that identifying and quantifying risks early helps ensure appropriate controls are in place before the integration, making risk assessment the most critical activity.

 The primary objective of the information security incident response process is to minimize the negative impact to critical operations. An information security incident is an event that threatens or compromises the confidentiality, integrity, or availability of the organization’s information assets or processes. The information security incident response process is a process that defines the roles, responsibilities, procedures, and tools for detecting, analyzing, containing, eradicating, recovering, and learning from information security incidents. The main goal of the information security incident response process is to restore the normal operations as quickly and effectively as possible, and to prevent or reduce the harm or loss caused by the incident to the organization, its stakeholders, or its environment.

Conducting incident triage (A) is an important activity of the information security incident response process, but not the primary objective. Incident triage is the process of prioritizing and assigning the incidents based on their severity, urgency, and impact. Incident triage helps to allocate the appropriate resources, personnel, and time to handle the incidents, and to escalate the incidents to the relevant authorities or parties if needed. However, incident triage is not the ultimate goal of the information security incident response process, but a means to achieve it.

Communicating with internal and external parties (B) is also an important activity of the information security incident response process, but not the primary objective. Communicating with internal and external parties is the process of informing and updating the stakeholders, such as management, employees, customers, partners, regulators, or media, about the incident status, actions, and outcomes. Communicating with internal and external parties helps to maintain the trust, confidence, and reputation of the organization, and to comply with the legal and contractual obligations, such as notification or reporting requirements. However, communicating with internal and external parties is not the ultimate goal of the information security incident response process, but a means to achieve it.

Classifying incidents (D) is also an important activity of the information security incident response process, but not the primary objective. Classifying incidents is the process of categorizing and labeling the incidents based on their type, source, cause, or impact. Classifying incidents helps to identify and understand the nature and scope of the incidents, and to apply the appropriate response procedures and controls. However, classifying incidents is not the ultimate goal of the information security incident response process, but a means to achieve it.

= A post-incident review is a process of analyzing and learning from a security incident, such as a data breach, to improve the security posture and resilience of an organization. A post-incident review should include the following elements12:

A clear and accurate description of the incident, including its scope, impact, timeline, root cause, and contributing factors.

A detailed assessment of the effectiveness and efficiency of the incident response process, including the roles and responsibilities, communication channels, coordination mechanisms, escalation procedures, tools and resources, documentation, and reporting.

An evaluation of the adequacy of existing controls, such as policies, standards, procedures, technical measures, awareness, and training, to prevent, detect, and mitigate similar incidents in the future.

A list of actionable recommendations and improvement plans, based on the lessons learned and best practices, to address the identified gaps and weaknesses in the security strategy, governance, risk management, and incident management.

A follow-up and monitoring mechanism to ensure the implementation and verification of the recommendations and improvement plans.

The most important element to include in a post-incident review following a data breach is the evaluation of the adequacy of existing controls, because it directly relates to the security objectives and requirements of the organization, and provides the basis for enhancing the security posture and resilience of the organization. Evaluating the existing controls helps to identify the vulnerabilities and risks that led to the data breach, and to determine the appropriate corrective and preventive actions to reduce the likelihood and impact of similar incidents in the future. Evaluating the existing controls also helps to align the security strategy and governance with the business goals and objectives, and to ensure the compliance with legal, regulatory, and contractual obligations.

The other elements, such as an evaluation of the effectiveness of the information security strategy, documentation of regulatory reporting requirements, and a review of the forensics chain of custody, are also important, but not as important as the evaluation of the existing controls. An evaluation of the effectiveness of the information security strategy is a broader and more strategic activity that may not be directly relevant to the specific incident, and may require more time and resources to conduct. Documentation of regulatory reporting requirements is a necessary and mandatory task, but it does not provide much insight or value for improving the security posture and resilience of the organization. A review of the forensics chain of custody is a technical and procedural activity that ensures the integrity and admissibility of the digital evidence collected during the incident investigation, but it does not address the root cause or the mitigation of the incident. References = 1: CISM Exam Content Outline | CISM Certification | ISACA 2: CISM Review Manual 15th Edition, page 147

 Improving security controls is an example of risk mitigation, which is the process of reducing the likelihood or impact of a risk. Risk mitigation can be achieved by implementing various strategies, such as purchasing insurance, discontinuing the activity associated with the risk, or improving security controls. Purchasing insurance is a form of risk transfer, which is the process of shifting the responsibility or burden of a risk to another party. Discontinuing the activity associated with the risk is a form of risk avoidance, which is the process of eliminating or avoiding a potential source of harm. Performing a cost-benefit analysis is a form of risk evaluation, which is the process of assessing the costs and benefits of different options to manage a risk. References = CISM Review Manual, 16th Edition, page 1741; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 802
