NEW QUESTION # 125
Which of the following characteristics ensures the security of an automated information system is the most effective and economical?
Answer: D
Explanation:
Comprehensive Detailed Explanation:The most effective and economical way to ensure the security of an automated information system is to design it with security in mind from the outset. This is often referred to as
"security by design." Here's a breakdown of each option and why option A is correct:
* A. Originally designed to provide necessary security
* Explanation: Systems designed with security from the beginning integrate secure practices and considerations during the development process. This approach mitigates the need for costly and complex retroactive security implementations, which are common in systems where security was an afterthought.
* Cost Efficiency: Security implementations at the design stage can be embedded into the system architecture, reducing the costs associated with later modifications.
* Effectiveness: Security-by-design approaches often result in robust systems that are more resilient to vulnerabilities because they address security concerns at each development phase.
* B. Subjected to intense security testing
* While rigorous security testing (such as penetration testing and vulnerability assessments) is essential, it is reactive. Security testing is more effective when applied to systems already designed with foundational security principles, ensuring that tests identify potential flaws in an inherently secure system.
* C. Customized to meet specific security threats
* Customizing security to meet specific threats addresses unique risks, but such a targeted approach may miss new or emerging threats not initially considered. It also risks neglecting fundamental security practices that apply universally, leading to potential vulnerabilities.
* D. Optimized prior to the addition of security
* Optimizing a system before adding security features may enhance performance but does not guarantee security. Security cannot be effectively added onto a system as an afterthought without incurring additional costs or creating potential weaknesses.

NEW QUESTION # 126
Which of the following best describes the goal of a tabletop exercise?
Answer: B
Explanation:
A tabletop exercise is a type of simulation exercise that involves testing possible incident scenarios and how to react properly, without actually performing any actions or using any resources. A tabletop exercise is usually conducted by a facilitator who presents a realistic scenario to a group of participants, such as a cyberattack, a natural disaster, or a data breach.
The participants then discuss and evaluate their roles, responsibilities, plans, procedures, and policies for responding to the incident, as well as the potential impacts and outcomes. A tabletop exercise can help identify strengths and weaknesses in the incident response plan, improve communication and coordination among the stakeholders, raise awareness and preparedness for potential incidents, and provide feedback and recommendations for improvement.
NEW QUESTION # 127
A cybersecurity team has witnessed numerous vulnerability events recently that have affected operating systems. The team decides to implement host-based IPS, firewalls and two-factor authentication. Which of the following does this most likely describe?
Answer: D
Explanation:
System hardening is the process of securing a system by reducing its attack surface, applying patches and updates, configuring security settings, and implementing security controls. System hardening can help prevent or mitigate vulnerability events that may affect operating systems.
Host-based IPS, firewalls, and two-factor authentication are examples of security controls that can be applied to harden a system.
NEW QUESTION # 128
An incident response analyst is taking over an investigation from another analyst. The investigation has been going on for the past few days. Which of the following steps is most important during the transition between the two analysts?
Answer: B
Explanation:
Reviewing the steps that the previous analyst followed is the most important step during the transition, as it ensures continuity and consistency of the investigation. It also helps the new analyst to understand the current status, scope, and findings of the investigation, and to avoid repeating the same actions or missing any important details. The other options are either less important, premature, or potentially biased. Reference: CompTIA CySA+ CS0-003 Certification Study Guide, Chapter 4: Incident Response and Management, page 191. Incident response best practices and tips, Tip 1: Always pack a jump bag.
NEW QUESTION # 129
An organization has tracked several incidents that are listed in the following table:
Which of the following is the organization's MTTD?
Answer: B
Explanation:
The MTTD (Mean Time To Detect) is calculated by averaging the time elapsed in detecting incidents. From the given data: (180+150+170+140)/4 = 160 minutes.
