CompTIA Cybersecurity Analyst (CySA+) Certification Exam CS0-004 Prüfungsfragen mit Lösungen (Q105-Q110):

105. Frage
A security analyst uses a full pcap solution to extract all traffic from the last two days associated with the 10.213.4.27 file server. This file server is under investigation due to concerns about potential data exfiltration using Domain Name System (DNS) traffic. Which of the following commands should the analyst use to extract any potentially leaked data from the suspicious.pcap file?

A. strings suspicious.pcap | grep 10.213.4.27
B. snort -r suspicious.pcap ; grep eve.log 10.213.4.27
C. zeek -r suspicious.pcap ; grep 10.213.4.27 file.log
D. tcpdump -r suspicious.pcap port 53 and host 10.213.4.27

Antwort: D

Begründung:
This command reads the packet capture and filters traffic involving the file server on DNS port 53, allowing the analyst to inspect potential DNS-based data exfiltration.

106. Frage
During a recent security event, log files were being sent to a stand-alone console that was not being checked on a daily basis. As a result, the stated SLA for detection was exceeded. Which of the following is a way to prevent this delay in the future?

A. Reevaluating the SLA for detection to reflect current operations
B. Decreasing the interval for sending logs from endpoints
C. Automating the process for ingesting logs into the stand-alone console
D. Using a centralized dashboard for monitoring

Antwort: D

Begründung:
The issue was not that logs were unavailable, but that they were being sent to a stand-alone console that was not routinely monitored. A centralized dashboard improves visibility by aggregating logs and alerts into a single monitoring platform, making it more likely that security events are detected within the required SLA.

107. Frage
Which of the following is the most important reason why tactics, techniques, and procedures (TTP) are beneficial to a defensive strategy?

A. TTP provides useful insights on an attacker's indicators of compromise.
B. TTP provides useful insights on the strategy and behavior of an attacker.
C. TTP provides useful insights on the hash values and internet protocol addresses attributed to an attacker.
D. TTP provides useful insights on the tools used by an attacker.

Antwort: B

Begründung:
Tactics, techniques, and procedures represent the behavioral characteristics of an adversary rather than merely individual technical artifacts. A tactic describes the adversary's objective, a technique identifies how that objective is achieved, and procedures represent the specific implementation observed during an intrusion.
Consequently, TTP intelligence allows defenders to understand how an attacker operates , including patterns of reconnaissance, persistence, privilege escalation, lateral movement, command-and-control activity, and other operational behaviors.
Options A and B focus primarily on indicators of compromise such as IP addresses and hashes. These are useful for detection, but they are comparatively fragile because attackers can replace infrastructure, change domains, regenerate malware, or modify files to produce different hashes. Option C is broader than an individual IoC, but tools can likewise be replaced or modified. Behavioral knowledge is generally more durable because changing established operational methods imposes greater cost on an adversary.
The CS0-004 objectives explicitly place TTPs, Pyramid of Pain, MITRE ATT & CK, attribution, IoC analysis, and behavioral indicators within threat intelligence and threat-hunting concepts.
Study Guide Reference: Security Operations # Threat Intelligence and Threat Hunting # TTPs # Pyramid of Pain # MITRE ATT & CK # Behavioral IoCs.

108. Frage
A security operations center (SOC) manager reviews a document signed by the Chief Financial Officer (CFO), the sales director, and a customer to decide whether a contract breach occurred.
Which of the following best describes the document that includes key performance indicators (KPIs)?

A. Return on investment report
B. Service-level agreement (SLA)
C. Risk management plan
D. Tactics, techniques, and procedures (TTPs)
E. Memorandum of understanding

Antwort: B

Begründung:
An SLA is a formal agreement that defines measurable service requirements, KPIs, responsibilities, and consequences when agreed performance levels are not met.

109. Frage
A Chief Information Security Officer (CISO) is notified of an ongoing incident.
Which of the following explains why the CISO instructs the Chief Executive Officer not to discuss the incident over email?

A. The CISO has not notified the public relations team of the incident.
B. The security team discovered a vulnerability in the Short Message Service email gateway.
C. Emails are not encrypted in transit.
D. The email system may be compromised.

Antwort: D

Begründung:
During an active cybersecurity incident, responders must assume that systems associated with the compromise may no longer provide trustworthy confidentiality or integrity until their status has been established. If the incident could involve the organization's email infrastructure, discussing response strategy, investigative findings, affected assets, or containment actions through corporate email could unintentionally provide the attacker with intelligence about the organization's response.
Therefore, the email system may be compromised is the strongest explanation. Incident-response communication plans should define approved communication methods, relevant stakeholders, escalation paths, and alternative communication channels so responders can continue coordinating when ordinary enterprise systems are unavailable or untrusted. NIST's current incident-response guidance emphasizes integrating communication and stakeholder coordination throughout response activities.
Option C is too broad. Modern email commonly uses transport encryption, although encryption alone would not make a compromised mailbox or server trustworthy. Option D concerns public-relations coordination but does not explain why email itself should be avoided. Option A describes a specific gateway vulnerability that the scenario does not establish.
The core principle is out-of-band communication : when normal communication infrastructure may be under attacker control, responders should use a previously approved independent channel.

# Out-of-Band Communications # Stakeholder Coordination # Compromised Communication Channels.
