During a tabletop exercise, engineers discovered that an ICS could not be updated due to hardware versioning incompatibility. Which of the following is the most likely cause of this issue?
The most likely cause of the issue where an ICS (Industrial Control System) could not be updated due to hardware versioning incompatibility is a legacy system. Legacy systems often have outdated hardware and software that may not be compatible with modern updates and patches. This can pose significant challenges in maintaining security and operational efficiency.
Which of the following best describes the key goal of the containment stage of an incident response process?
The key goal of the containment stage in an incident response process is to limit further damage from occurring. This involves taking immediate steps to isolate the affected systems or network segments to prevent the spread of the incident and mitigate its impact. Containment strategies can be short-term, to quickly stop the incident, or long-term, to prepare for the eradication and recovery phases.

A security analyst has prepared a vulnerability scan that contains all of the company's functional subnets. During the initial scan, users reported that network printers began to print pages that contained unreadable text and icons.
Which of the following should the analyst do to ensure this behavior does not oocur during subsequent vulnerability scans?
The best way to prevent network printers from printing pages during a vulnerability scan is to create a tailored scan for the printer subnet that excludes the ports and services that trigger the printing behavior. The other options are not effective for this purpose: performing non-credentialed scans may not reduce the impact on the printers; ignoring embedded web server ports may not cover all the possible ports that cause printing; increasing the threshold length of the scan timeout may not prevent the printing from occurring.
According to the CompTIA CySA+ Study Guide: Exam CS0-003, 3rd Edition1, one of the objectives for the exam is to ''use appropriate tools and methods to manage, prioritize and respond to attacks and vulnerabilities''. The book also covers the usage and syntax of vulnerability scanning tools, such as Nessus, Nmap, and Qualys, in chapter 4. Specifically, it explains the meaning and function of each component in vulnerability scanning, such as credentialed vs. non-credentialed scans, port scanning, and scan scheduling1, pages 149-160. It also discusses the common issues and challenges of vulnerability scanning, such as network disruptions, false positives, and scan scope1, pages 161-162. Therefore, this is a reliable source to verify the answer to the question.
The Chief Information Security Officer (CISO) of a large management firm has selected a cybersecurity framework that will help the organization demonstrate its investment in tools and systems to protect its dat
a. Which of the following did the CISO most likely select?
ISO 27001 is an international standard that establishes a framework for implementing, maintaining, and improving an information security management system (ISMS). It helps organizations demonstrate their commitment to protecting their data and complying with various regulations and best practices. The other options are not relevant for this purpose: PCI DSS is a standard that focuses on protecting payment card data; COBIT is a framework that provides guidance on governance and management of enterprise IT; ITIL is a framework that provides guidance on service management and delivery.
According to the CompTIA CySA+ Study Guide: Exam CS0-003, 3rd Edition1, one of the objectives for the exam is to ''use appropriate tools and methods to manage, prioritize and respond to attacks and vulnerabilities''. The book also covers the usage and syntax of various cybersecurity frameworks and standards, such as ISO 27001, PCI DSS, COBIT, and ITIL, in chapter 1. Specifically, it explains the meaning and function of each framework and standard, such as ISO 27001, which provides a comprehensive approach to information security management1, page 29. Therefore, this is a reliable source to verify the answer to the question.
