An investigation of a recent security incident determined that the root cause was negligent handing of incident alerts by system admit manager to address this issue?
Correct Answer:
C
The best action for the system admin manager to address the issue of negligent handling of incident alerts by system admins is to provide incident response training to data custodians because it helps to improve their awareness and skills in recognizing and reporting security incidents, and following the incident response procedures and protocols. Conducting a risk assessment and sharing the result with senior management is not a good action because it does not address the root cause of the issue or provide any solutions or improvements. Revising the incident response plan to align with business processes is not a good action because it does not address the root cause of the issue or provide any solutions or improvements. Providing incident response training to data owners is not a good action because data owners are not responsible for handling incident alerts or performing incident response tasks.

Which of the following service offerings in a typical Infrastructure as a Service (laaS) model will BEST enable a cloud service provider to assist customers when recovering from a security incident?
Correct Answer:
D
A snapshot is a point-in-time copy of the state of a virtual machine (VM) that can be used to restore the VM to a previous state in case of a security incident or a disaster. A snapshot can capture the VM’s disk, memory, and device configuration, allowing for a quick and easy recovery of the VM’s data and functionality. Snapshots can also be used to create backups, clones, or replicas of VMs for testing, analysis, or migration purposes. Snapshots are a common service offering in Infrastructure as a Service (IaaS) models, where customers can provision and manage VMs on demand from a cloud service provider (CSP). A CSP that offers the capability to take snapshots of VMs can assist customers when recovering from a security incident by providing them with the following benefits12:
✑ Faster recovery time: Snapshots can reduce the downtime and data loss caused by a security incident by allowing customers to quickly revert their VMs to a known good state. Snapshots can also help customers avoid the need to reinstall or reconfigure their VMs after an incident, saving time and resources.
✑ Easier incident analysis: Snapshots can enable customers to perform online or offline analysis of their VMs after an incident, without affecting the production environment. Customers can use snapshots to examine the VM’s disk, memory, and logs for evidence of compromise, root cause analysis, or forensic investigation. Customers can also use snapshots to test and validate their incident response plans or remediation actions before applying them to the production VMs.
✑ Enhanced security posture: Snapshots can improve the security posture of customers by enabling them to implement best practices such as backup and restore, disaster recovery, and business continuity. Snapshots can help customers protect their VMs from accidental or malicious deletion, corruption, or modification, as well as from environmental or technical disruptions. Snapshots can also help customers comply with regulatory or contractual requirements for data retention, availability, or integrity.

Which of the following should an information security manager do FIRST upon learning that some security hardening settings may negatively impact future business activity?
Correct Answer:
A
Security hardening is the process of applying security configuration settings to systems and software to reduce their attack surface and improve their resistance to threats1. Security hardening settings are based on industry standards and best practices, such as the CIS Benchmarks2, which provide recommended security configurations for various software applications, operating systems, and network devices. However, security hardening settings may not always be compatible with the business requirements and objectives of an organization, and may negatively impact the functionality, performance, or usability of the systems and software3. Therefore, before applying any security hardening settings, an information security manager should perform a risk assessment to evaluate the potential benefits and drawbacks of the settings, and to identify and prioritize the risks associated with them. A risk assessment is a systematic process of identifying, analyzing, and evaluating the risks that an organization faces, and determining the appropriate risk responses. A risk assessment helps the information security manager to balance the security and business needs of the organization, and to communicate the risk level and impact to the relevant stakeholders. A risk assessment should be performed first, before taking any other actions, such as reducing security hardening settings, informing business management of the risk, or documenting a security exception, because it provides the necessary information and justification for making informed and rational decisions.

An organization learns that a third party has outsourced critical functions to another external provider. Which of the following is the information security manager's MOST important course of action?
Correct Answer:
C
According to the CISM Review Manual, the information security manager should evaluate the third party’s agreements with its external provider to ensure that the security requirements and controls are adequate and consistent with the organization’s expectations. Engaging or conducting an audit may be a subsequent step, but not the most important one. Recommending canceling the contract may be premature and impractical.

A new application has entered the production environment with deficient technical security controls. Which of the following is MOST Likely the root cause?
Correct Answer:
C
Change control is the process of ensuring that changes to an information system are authorized, tested, documented and implemented in a controlled manner. Inadequate change control can result in deficient technical security controls, such as missing patches, misconfigurations, vulnerabilities or errors in the new application.
