CompTIA Cybersecurity Analyst (CySA+) Certification Exam CS0-004 Prüfungsfragen mit Lösungen (Q86-Q91):

86. Frage
Which of the following best explains why sensitive data should be encrypted at rest on laptops?

A. To ensure the integrity of the data on the company network
B. To prevent end users from copying data to other systems
C. To protect disclosure of information if physical devices are stolen
D. To comply with regulatory and legal requirements

Antwort: C

Begründung:
Encryption at rest primarily protects the confidentiality of stored information when an unauthorized party obtains physical or logical access to the storage medium. This is particularly important for laptops because portable devices can be lost or stolen, giving an attacker possession of the disk outside the organization's normal network and endpoint protections.
NIST guidance on storage encryption specifically addresses laptops and other end-user devices and explains that storage encryption combines encryption and authentication to restrict unauthorized access to stored information. NIST further notes that threats involving lost or stolen end-user devices can expose information to unauthorized parties.
Encryption does not inherently prevent an authenticated and authorized user from copying information while the system is unlocked; data loss prevention controls are more directly suited to that objective. Regulatory requirements may mandate encryption in some environments, but compliance is an external requirement rather than the fundamental security reason encryption at rest exists. Option D confuses confidentiality with integrity and network protection. Encryption of data stored on a laptop is not primarily intended to validate whether network data has been modified.
The examination concept is the CIA triad: encryption primarily supports confidentiality , especially when physical possession of the storage device is lost.
Study Guide Reference: Security Operations # Data Protection # Encryption at Rest # Full-Disk Encryption
# Confidentiality # Lost/Stolen Endpoint Protection.

87. Frage
A cybersecurity analyst requests a paid subscription to a threat intelligence feed relevant to a company's industry.
Which of the following best describes this type of feed?

A. Threat modeling
B. Threat mapping
C. Open-source intelligence
D. Closed-source intelligence

Antwort: D

Begründung:
A paid, subscription-based threat intelligence service is best classified as closed-source intelligence because access is restricted to authorized subscribers rather than being freely available to the public. Commercial threat-intelligence providers typically collect, analyze, correlate, and curate indicators and adversary information before distributing that intelligence through authenticated portals, APIs, or feeds.
NIST identifies several external intelligence-source categories, including open-source repositories, commercial threat feeds, and external information-sharing partners . A commercial feed relevant to a company's specific industry may provide higher-context intelligence regarding threat actors, infrastructure, malware, vulnerabilities, campaigns, and indicators affecting that vertical.
OSINT, by contrast, originates from publicly accessible sources and normally does not require restricted subscription access. Threat mapping is the activity of associating adversary behavior or intelligence with infrastructure, campaigns, frameworks, or organizational assets. Threat modeling is a structured process used to identify potential threats and weaknesses in systems or applications; it is not an intelligence-source classification.
The examination clue is "paid subscription." Restricted commercial access distinguishes the feed from publicly obtainable OSINT.

88. Frage
An analyst receives the following summary report for vulnerabilities on multiple hosts:

Which of the following servers should the analyst remediate first?

A. COMPTIA-WEB01
B. COMPTIA-FS01
C. COMPTIA-DC01
D. COMPTIA-APP01

Antwort: D

Begründung:
The internal application server has the highest number of high-severity vulnerabilities. High- severity vulnerabilities present the greatest immediate risk because they are more likely to be exploited and can result in significant compromise of systems or data. Since this server has the largest concentration of critical issues, it should be prioritized for remediation.

89. Frage
A vulnerability analyst conducts a web application scan on an asset sitting behind a load balancer configured as a pass through:
http://10.203.20.10
The analyst launches the Zed Attack Proxy (ZAP) utility, conducts a scan, and receives the following alert:

Which of the following should the analyst propose as a remediation to the finding while keeping the site operational?

A. Ensure the Hypertext Transfer Protocol (HTTP) endpoint is protected with a network firewall with geo- blocking.
B. Ensure the load balancer is configured with online certificate status protocol (OCSP) stapling.
C. Ensure the web application is configured to suppress the "Server" header.
D. Ensure the web server host-based firewall is configured to block HTTP incoming traffic.

Antwort: C

Begründung:
The ZAP finding concerns information disclosure through the HTTP Server response header , so the correct remediation is to suppress or minimize that header while leaving the website operational. OWASP ZAP maintains specific alerts for servers that disclose the web-server application or version through this response field. The version-disclosure rule is categorized as information exposure because detailed server identification can assist reconnaissance and vulnerability targeting.
Removing unnecessary product and version information reduces information available to an attacker without interrupting legitimate HTTP requests. This directly satisfies the requirement to remediate the finding while maintaining service availability.
Geo-blocking does not correct server-version disclosure and may unnecessarily deny legitimate users based on location. OCSP stapling relates to certificate-revocation status in TLS and is irrelevant to an HTTP server- header disclosure. Blocking incoming HTTP entirely would make the current endpoint unavailable, contradicting the requirement to keep the site operational.
The remediation principle is therefore minimize externally exposed implementation details while preserving application functionality . Server banners are not themselves an exploit, but they can improve an attacker's ability to fingerprint technology and select applicable exploits.
Study Guide Reference: Vulnerability Management # Web Application Scanning # OWASP ZAP # Information Disclosure # HTTP Server Headers # Banner Suppression # Secure Configuration.

90. Frage
Which of the following is the most difficult for threat actors to change according to the Pyramid of Pain model?

A. Domain names
B. Internet Protocol addresses
C. Tools
D. Tactics, techniques, and procedures

Antwort: D

Begründung:
TTPs reflect an attacker's established behavior and operational methods, making them much harder to change than tools, domains, or IP addresses.
