| A. The risk would not change because network firewalls are in use. | | B. The risk would decrease because RDP is blocked by the firewall. | | C. The risk would decrease because a web application firewall is in place. | | D. The risk would increase because the host is external facing. |
B. The risk would decrease because RDP is blocked by the firewall.
Question # 2

A. Geoblock the offending source country.
Question # 4
| A company is deploying new vulnerability scanning software to assess its systems. The current network is highly segmented, and the networking team wants to minimize the number of unique firewall rules. Which of the following scanning techniques would be most efficient to achieve the objective? |

Which of the following tuning recommendations should the security analyst share? |
| A. Set an HttpOnly flag to force communication by HTTPS | | B. Block requests without an X-Frame-Options header | | C. Configure an Access-Control-Allow-Origin header to authorized domains | | D. Disable the cross-origin resource sharing header |
B. Block requests without an X-Frame-Options header
Question # 6
| A zero-day command injection vulnerability was published. A security administrator is analyzing the following logs for evidence of adversaries attempting to exploit the vulnerability. Which of the following log entries provides evidence of the attempted exploit? |
| A. Log entry 1 | | B. Log entry 2 | | C. Log entry 3 | | D. Log entry 4 |
A. Log entry 1
Question # 7
| A security team is concerned about recent Layer 4 DDoS attacks against the company website. Which of the following controls would best mitigate the attacks? |
| A. Block the attacks using firewall rules. | | B. Deploy an IPS in the perimeter network. | | C. Roll out a CDN. | | D. Implement a load balancer. |
C. Roll out a CDN.
Explanation:
Rolling out a CDN is the best control to mitigate the Layer 4 DDoS attacks against the company website. A CDN is a Content Delivery Network, which is a system
of distributed servers that deliver web content to users based on their geographic location, the origin of the web page, and the content delivery server. A CDN can
help protect against Layer 4 DDoS attacks, which are volumetric attacks that aim to exhaust the network bandwidth or resources of the target website by sending a
large amount of traffic, such as SYN floods, UDP floods, or ICMP floods. A CDN can mitigate these attacks by distributing the traffic across multiple servers,
caching the web content closer to the users, filtering out malicious or unwanted traffic, and providing scalability and redundancy for the website.
Question # 8
A security analyst must preserve a system hard drive that was involved in a litigation request Which of the following is the best method to ensure the data on the device is not modified?
|
A. Generate a hash value and make a backup image.
| B. Encrypt the device to ensure confidentiality of the data.
| C. Protect the device with a complex password.
| D. Perform a memory scan dump to collect residual data.
|
A. Generate a hash value and make a backup image.
Explanation:
Generating a hash value and making a backup image is the best method to ensure the data on the device is not modified, as it creates a verifiable copy of the original data that can be used for forensic analysis. Encrypting the device, protecting it with a password, or performing a memory scan dump do not prevent the data from being altered or deleted.

Question # 9
Which of the following items should be included in a vulnerability scan report? (Choose two.)
|
A. Lessons learned
| B. Service-level agreement
| C. Playbook
| D. Affected hosts
| E. Risk score
|
D. Affected hosts
E. Risk score
Explanation:
A vulnerability scan report should include information about the affected hosts, such as their IP addresses, hostnames, operating systems, and services. It should also include a risk score for each vulnerability, which indicates the severity and potential impact of the vulnerability on the host and the organization.

Question # 10
An analyst is suddenly unable to enrich data from the firewall. However, the other open intelligence feeds continue to work. Which of the following is the most likely reason the firewall feed stopped working?
|
A. The firewall service account was locked out.
| B. The firewall was using a paid feed.
| C. The firewall certificate expired.
| D. The firewall failed open.
|
C. The firewall certificate expired.
Explanation:
The firewall certificate expired. If the firewall uses a certificate to authenticate and encrypt the feed, and the certificate expires, the feed will stop working until the certificate is renewed or replaced. This can affect the data enrichment process and the security analysis. References: CompTIA CySA+ Study Guide: Exam CS0-003, 3rd Edition, Chapter 4: Security Operations and Monitoring, page 161.

This exam tests not just theoretical knowledge, but also hands-on skills in addressing and neutralizing cyber threats.
Yes, CySA+ is generally considered more challenging than Security+. While Security+ serves as an entry-level certification focusing on foundational security concepts, CySA+ delves deeper into cybersecurity, particularly in threat detection and response. It requires a stronger grasp of security analytics, applying knowledge in more complex, scenario-based contexts.
CySA+ (CompTIA Cybersecurity Analyst) is not typically considered entry-level; it's more of an intermediate certification. It's designed for IT professionals who already have foundational knowledge and experience in cybersecurity, especially in areas like threat detection and response.
Yes, CySA+ is an excellent certification for those looking to enhance their cybersecurity careers. It's highly respected in the IT industry and focuses on practical, relevant skills in cybersecurity analysis, such as threat detection and response.
