Ensuring accountability for changes to the environment is the primary reason for implementing change management. Change management is a process that ensures that any changes to the system or network environment, such as the hardware, software, configuration, or documentation, are planned, approved, implemented, and documented in a controlled and consistent manner. Change management can provide several benefits, such as:

• Improving the security and reliability of the system or network environment by preventing or reducing the errors, conflicts, or disruptions that might occur due to the changes
• Enhancing the performance and efficiency of the system or network environment by optimizing the resources and functions
• Increasing the compliance and alignment of the system or network environment with the internal or external requirements and standards
• Facilitating the monitoring and improvement of the system or network environment by tracking and logging the changes and their outcomes

Ensuring accountability for changes to the environment is the primary reason for implementing change management, because it can ensure that the changes are authorized, justified, and traceable, and that the parties involved in the changes are responsible and accountable for their actions and results. Accountability can also help to deter or detect any unauthorized or malicious changes that might compromise the system or network environment.

The other options are not the primary reasons for implementing change management, but rather secondary or specific reasons for different aspects or phases of change management. Certifying and approving releases to the environment is a reason for implementing change management, but it is more relevant for the approval phase of change management, which is the phase that involves reviewing and validating the changes and their impacts, and granting or denying the permission to proceed with the changes. Providing version rollbacks for system changes is a reason for implementing change management, but it is more relevant for the implementation phase of change management, which is the phase that involves executing and monitoring the changes and their effects, and providing the backup and recovery options for the changes. Ensuring that all applications are approved is a reason for implementing change management, but it is more relevant for the application changes, which are the changes that affect the software components or services that provide the functionality or logic of the system or network environment.

Write blocking devices are used to prevent any modification of the forensic evidence when it is examined. This preserves the integrity of the evidence and ensures its admissibility in court. Write blocking devices do not affect the inventory, confidentiality, or availability of the evidence. References: 1, p. 1030; [4], p. 17

Recovery strategies of a Disaster Recovery planning (DRP) must be aligned with the cost/benefit analysis and business objectives. A DRP is a part of a BCP/DRP that focuses on restoring the normal operation of the organization’s IT systems and infrastructure after a disruption or disaster. A DRP should include various components, such as:

• Risk assessment: a process that identifies and evaluates the potential threats and vulnerabilities that might affect the IT systems and infrastructure, and estimates the likelihood and impact of a disruption or disaster
• Recovery objectives: a process that defines and quantifies the acceptable levels of recovery for the IT systems and infrastructure, such as the recovery point objective (RPO), which is the maximum amount of data loss that can be tolerated, and the recovery time objective (RTO), which is the maximum amount of downtime that can be tolerated
• Recovery strategies: a process that selects and implements the appropriate methods and resources to recover the IT systems and infrastructure, such as backup, replication, redundancy, or failover
• DRP document: a document that outlines and details the scope, purpose, and features of the DRP, such as the roles and responsibilities, the recovery procedures, and the contact information
• Testing, training, and exercises: a process that evaluates and validates the effectiveness and readiness of the DRP, and educates and trains the relevant stakeholders, such as the IT staff, the management, and the users, on the DRP and their roles and responsibilities
• Maintenance and review: a process that monitors and updates the DRP, and addresses any changes or issues that might affect the DRP, such as the IT requirements, the threat landscape, or the feedback and lessons learned

Recovery strategies of a DRP must be aligned with the cost/benefit analysis and business objectives, because it can ensure that the DRP is feasible and suitable, and that it can achieve the desired outcomes and objectives in a cost-effective and efficient manner. A cost/benefit analysis is a technique that compares the costs and benefits of different recovery strategies, and determines the optimal one that provides the best value for money. A business objective is a goal or a target that the organization wants to achieve through its IT systems and infrastructure, such as increasing the productivity, profitability, or customer satisfaction. A recovery strategy that is aligned with the cost/benefit analysis and business objectives can help to:

• Optimize the use and allocation of the IT resources and funds for the recovery
• Minimize the negative impacts and risks of a disruption or disaster on the IT systems and infrastructure
• Maximize the positive outcomes and benefits of the recovery for the IT systems and infrastructure
• Support and enable the achievement of the organizational goals and targets through the IT systems and infrastructure

The other options are not the factors that the recovery strategies of a DRP must be aligned with, but rather factors that should be considered or addressed when developing or implementing the recovery strategies of a DRP. Hardware and software compatibility issues are factors that should be considered when developing the recovery strategies of a DRP, because they can affect the functionality and interoperability of the IT systems and infrastructure, and may require additional resources or adjustments to resolve them. Applications’ criticality and downtime tolerance are factors that should be addressed when implementing the recovery strategies of a DRP, because they can determine the priority and urgency of the recovery for different applications, and may require different levels of recovery objectives and resources. Budget constraints and requirements are factors that should be considered when developing the recovery strategies of a DRP, because they can limit the availability and affordability of the IT resources and funds for the recovery, and may require trade-offs or compromises to balance them.
