질문 # 142
A security professional is investigating a trend in vulnerability findings for newly deployed cloud systems Given the following output:
Which of the following actions would address the root cause of this issue?
정답：D
설명：
The output shows that multiple systems have outdated or vulnerable software versions (OpenSSL 1.01 and Java 11 runtime). This suggests that the systems are not being patched regularly or effectively.
A: Automating the patching system to update base images: Automating the patching process ensures that the latest security updates and patches are applied to all systems, including newly deployed ones. This addresses the root cause by ensuring that base images used for deployment are always up-to-date with the latest security patches.
B: Recompiling the affected programs with the most current patches: While this can fix the immediate vulnerabilities, it does not address the root cause of the problem, which is the lack of regular updates.
C: Disabling unused/unneeded ports on all servers: This improves security but does not address the specific issue of outdated software.
D: Deploying a WAF with virtual patching upstream of the affected systems: This can provide a temporary shield but does not resolve the underlying issue of outdated software.
Automating the patching system to update base images ensures that all deployed systems are using the latest, most secure versions of software, addressing the root cause of the vulnerability trend.

질문 # 143
SIMULATION
[Security Architecture]
An organization is planning for disaster recovery and continuity ofoperations, and has noted the following relevant findings:
1. A natural disaster may disrupt operations at Site A, which would then cause an evacuation. Users are unable to log into the domain from-their workstations after relocating to Site B.
2. A natural disaster may disrupt operations at Site A, which would then cause the pump room at Site B to become inoperable.
3. A natural disaster may disrupt operations at Site A, which would then cause unreliable internet connectivity at Site B due to route flapping.
INSTRUCTIONS
Match each relevant finding to the affected host by clicking on the host name and selecting the appropriate number.
For findings 1 and 2, select the items that should be replicated to Site B. For finding 3, select the item requiring configuration changes, then select the appropriate corrective action from the drop-down menu.
정답：
설명：
See the solution below in Explanation
Explanation:
Matching Relevant Findings to the Affected Hosts:
Finding 1:
Affected Host: DNS
Reason: Users are unable to log into the domain from their workstations after relocating to Site B, which implies a failure in domain name services that are critical for user authentication and domain login.
Finding 2:
Affected Host: Pumps
Reason: Thepump room at Site B becoming inoperable directly points to the critical infrastructure components associated with pumping operations.
Finding 3:
Affected Host: VPN Concentrator
Reason: Unreliable internet connectivity at Site B due to route flapping indicates issues with network routing, which is often managed by VPN concentrators that handle site-to-site connectivity.
Corrective Actions for Finding 3:
Finding 3 Corrective Action:
Action: Modify the BGP configuration
Reason: Route flapping is often related to issues with Border Gateway Protocol (BGP) configurations. Adjusting BGP settings can stabilize routes and improve internet connectivity reliability.
Replication to Site B for Finding 1:
Affected Host: DNS
Domain Name System (DNS) services are essential for translating domain names into IP addresses, allowing users to log into the network. Replicating DNS services ensures that even if Site A is disrupted, users at Site B can still authenticate and access necessary resources.
Replication to Site B for Finding 2:
Affected Host: Pumps
The operation of the pump room is crucial for maintaining various functions within the infrastructure. Replicating the control systems and configurations for the pumps at Site B ensures that operations can continue smoothly even if Site A is affected.
Configuration Changes for Finding 3:
Affected Host: VPN Concentrator
Route flapping is a situation where routes become unstable, causing frequent changes in the best path for data to travel. This instability can be mitigated by modifying BGP configurations to ensure more stable routing. VPN concentrators, which manage connections between sites, are typically configured with BGP for optimal routing.
Reference:
CompTIA Security+ Study Guide: This guide provides detailed information on disaster recovery and continuity of operations, emphasizing the importance of replicating critical services and making necessary configuration changes to ensure seamless operation during disruptions.
CompTIA Security+ Exam Objectives: These objectives highlight key areas in disaster recovery planning, including the replication of critical services and network configuration adjustments.
Disaster Recovery and Business Continuity Planning (DRBCP): This resource outlines best practices for ensuring that operations can continue at an alternate site during a disaster, including the replication of essential services and network stability measures.
By ensuring that critical services like DNS and control systems for pumps are replicated at the alternate site, and by addressing network routing issues through proper BGP configuration, the organization can maintain operational continuity and minimize the impact of natural disasters on their operations.
질문 # 144
After an incident occurred, a team reported during the lessons-learned review that the team.
* Lost important Information for further analysis.
* Did not utilize the chain of communication
* Did not follow the right steps for a proper response
Which of the following solutions is the best way to address these findinds?
정답：D
설명：
Building playbooks for different scenarios and performing regular table-top exercises directly addresses the issues identified in the lessons-learned review. Here's why:
Lost important information for further analysis: Playbooks outline step-by-step procedures for incident response, ensuring that team members know exactly what to document and how to preserve evidence.
Did not utilize the chain of communication: Playbooks include communication protocols, specifying who to notify and when. Regular table-top exercises reinforce these communication channels, ensuring they are followed during actual incidents.
Did not follow the right steps for a proper response: Playbooks provide a clear sequence of actions to be taken during various types of incidents, helping the team to respond in a structured and effective manner. Regular exercises allow the team to practice these steps, identifying and correcting any deviations from the plan.
Investing in better forensic tools (Option A) or requiring certifications (Option C) are also valuable, but they do not directly address the procedural and communication gaps identified. Publishing and enforcing the incident response policy (Option D) is important but not as practical and hands-on as playbooks and exercises in ensuring the team is prepared.
질문 # 145
An administrator brings the company's fleet of mobile devices into its PKI in order to align device WLAN NAC configurations with existing workstations and laptops. Thousands of devices need to be reconfigured in a cost-effective, time-efficient, and secure manner. Which of the following actions best achieve this goal?
(Select two)
정답：E,F
설명：
Comprehensive and Detailed Explanation:
For bulk PKI enrollment:
* MDM integration with directory services streamlines certificate request and deployment per device, leveraging existing authentication methods.
* Simple Certificate Enrollment Protocol (SCEP) with one-time passwords allows automated, secure, large-scale certificate issuance without manual CSR handling.
* clientAuth templates are used for device authentication, but selecting it alone is insufficient without automated enrollment mechanisms.
* A single certificate for all devices violates PKI security principles and compromises individual device accountability.
질문 # 146
Following a security incident, a company decides to improve its device management.
The company establishes the following requirements for the new process:
- EOL devices must be properly replaced in a timely manner.
- Accurate, detailed information about the devices must be available in a centralized repository.
Which of the following should the company do to meet these requirements? (Choose two.)
정답：B,C
설명：
Implementing an asset management life cycle ensures EOL devices are tracked and replaced in a timely manner.
Maintaining a configuration management database (CMDB) provides a centralized repository with accurate and detailed device information.
