CompTIA Cybersecurity Analyst (CySA+) Certification Exam 認定 CS0-003 試験問題 (Q409-Q414):

質問 # 409
A company wants to grant access to identity administrators who are completing similar tasks.
Which of the following access control models should the company use?

正解：A

解説：
Role-based access control (RBAC) assigns permissions based on job roles, allowing identity administrators who perform similar tasks to have the same level of access efficiently and securely.


質問 # 410
A company has the following security requirements:
. No public IPs
All data secured at rest
. No insecure ports/protocols
After a cloud scan is completed, a security analyst receives reports that several misconfigurations are putting the company at risk. Given the following cloud scanner output:

Which of the following should the analyst recommend be updated first to meet the security requirements and reduce risks?

正解：B

解説：
To determine the highest priority for remediation, we must compare the configuration of each VM against the three mandatory security requirements:
No public IPs
All data secured at rest (Encryption = Yes)
No insecure ports/protocols (No unencrypted protocols like HTTP/Telnet)
1. Analyze the Compliance of VM_PRD_DB (Option A):
Asset Type: Production Database (High Value Target).
IP Config: public - > FAIL. (A production database should never be directly exposed to the internet; it should reside in a private subnet).
Encryption: no - > FAIL. (Violates the " data secured at rest " policy).
Ingress Port: 80 (HTTP) - > FAIL. (Port 80 is cleartext/unencrypted. Using an insecure protocol on a public interface puts data confidentiality at immediate risk).
Conclusion: This asset violates all three security policies and exposes the organization ' s most critical data (Production DB) to the public internet via an insecure channel.
2. Why the other options are lower priority:
B). VM_DEV_DB:
It uses a private IP (Pass) and Port 443 (Secure). It only fails the " Encryption " check. Since it is a Development box and not publicly exposed, the risk is significantly lower.
C). VM_DEV_Web02:
It exposes Port 22 (SSH). While exposing SSH to the internet is poor practice, SSH is a secure protocol (encrypted), unlike Port 80. It also has encryption at rest enabled.
D). VM_PRD_Web01:
It exposes Port 3389 (RDP). While RDP is a common attack vector (ransomware entry point), the server has " Encryption at rest " enabled (Pass).
Comparison: While VM_PRD_Web01 is risky due to RDP, VM_PRD_DB is riskier because it involves a Database (higher impact than a web server) communicating over Port 80 (cleartext) with No Encryption at rest.


質問 # 411
An employee received a phishing email that contained malware targeting the company. Which of the following is the best way for a security analyst to get more details about the malware and avoid disclosing information?

正解：C

解説：
Comprehensive Detailed Explanation:To safely analyze malware while avoiding unintended disclosure of company information, it is best to use a local sandbox in a microsegmented environment. Here's why:
A). Upload the malware to the VirusTotal website
Risk: VirusTotal and similar services are public and may share uploaded files with other security vendors, potentially exposing proprietary or sensitive information.
B). Share the malware with the EDR provider
Limitation: While EDR providers may offer insight, sharing potentially sensitive malware samples externally still introduces risk of disclosure or data leaks.
C). Hire an external consultant to perform the analysis
Cost and Risk: Hiring an external consultant can be costly and may introduce risks related to third-party handling of sensitive data. Although it may provide insights, this is typically not the most efficient initial response.
D). Use a local sandbox in a microsegmented environment
A local sandbox provides a secure, isolated environment for malware analysis without exposing sensitive data outside the organization. Microsegmentation enhances security by further isolating the sandbox from the network, preventing lateral movement if the malware attempts to communicate externally.

質問 # 412
A security analyst is tasked with prioritizing vulnerabilities for remediation. The relevant company security policies are shown below:
Security Policy 1006: Vulnerability Management
1. The Company shall use the CVSSv3.1 Base Score Metrics (Exploitability and Impact) to prioritize the remediation of security vulnerabilities.
2. In situations where a choice must be made between confidentiality and availability, the Company shall prioritize confidentiality of data over availability of systems and data.
3. The Company shall prioritize patching of publicly available systems and services over patching of internally available system.
According to the security policy, which of the following vulnerabilities should be the highest priority to patch?

正解：C

解説：
According to the security policy, the company shall use the CVSSv3.1 Base Score Metrics to prioritize the remediation of security vulnerabilities. Option C has the highest CVSSv3.1 Base Score of 9.8, which indicates a critical severity level. The company shall also prioritize confidentiality of data over availability of systems and data, and option C has a high impact on confidentiality (C:H). Finally, the company shall prioritize patching of publicly available systems and services over patching of internally available systems, and option C affects a public-facing web server.

質問 # 413
A web application has a function to retrieve content from an internal URL to identify CSRF attacks in the logs. The security analyst is building a regular expression that will filter out the correctly formatted requests. The target URL is https://10.1.2.3/api, and the receiving API only accepts GET requests and uses a single integer argument named "id." Which of the following regular expressions should the analyst use to achieve the objective?

正解：A

解説：
The correct regular expression to match a GET request to this API endpoint is
"https://10\.1\.2\.3/api\?id=\d+". This pattern checks for the specific URL with an id parameter that accepts integer values. The syntax \d+ matches one or more digits, which aligns with the requirement for a single integer argument. Other options either use incorrect syntax or do not accurately capture the expected URL format.
