近年、IT技術の急速な発展に伴って、IT技術を勉強し始める人がますます多くなっています。そこで、IT業界で働く人も多くなっています。このように、IT業界の競争が一層激しくなります。同様にIT業界で働いていて、IT夢を持っているあなたは、きっと他の人にキャッチアップされ、追い抜かれることを望まないでしょう。それでは、ずっと自分自身のスキルをアップグレードすることが必要になり、他の人に自分の強さを証明する必要があります。では、どうやって自分の能力を証明するのですか。多くの人々はIT認定試験を受験して認証資格を取ることを通して彼らの強さを証明します。あなたもIT認証資格を取りたいですか。まずCompTIAのCS0-004認定試験に合格しましょう。これはCompTIAの最も重要な試験の一つで、業界全体に認証された資格です。

CompTIA Cybersecurity Analyst (CySA+) Certification Exam 認定 CS0-004 試験問題 (Q93-Q98):

質問 # 93
Before merging with a software company, the acquiring company's legal team requires a detailed software scan to determine if all code base is using open-source or paid licensed libraries. The vulnerability management analyst needs to provide this report. Which of the following scan methods will best meet this requirement?

A. Credentialed vulnerability scan
B. Dynamic application security testing (DAST)
C. Static application security testing (SAST)
D. Runtime application self-protection (RASP)
E. Software composition analysis (SCA)

正解：E

解説：
SCA inventories third-party and open-source components, identifies their licenses, and detects associated vulnerabilities, making it the best method for software licensing due diligence.

質問 # 94
Which of the following is the most difficult for threat actors to change according to the Pyramid of Pain model?

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

正解：D

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

質問 # 95
A security analyst responds to an incident and finds the attacker embedded in the critical infrastructure. There is no evidence of lateral movement in the past 30 days. Which of the following is the most likely type of threat actor in the system?

A. Hacktivist
B. Script kiddie
C. Nation-state
D. Organized crime

正解：C

解説：
A nation-state threat actor is the most likely candidate because these actors are known for establishing long-term, persistent access to critical infrastructure targets. Their objectives often involve espionage, strategic positioning, or preparation for future operations, allowing them to remain embedded within systems for extended periods while minimizing detectable activity such as lateral movement.

質問 # 96
The Chief Information Security Officer wants to improve internal security measures by continuously validating and verifying access to the production environment.
Which of the following concepts best describes this practice?

A. Secure access service edge
B. Next-generation firewall
C. Privileged access management
D. Zero Trust

正解：D

解説：
Zero Trust is based on the principle that access should not be implicitly trusted merely because a user, workload, or device has already entered the enterprise environment. Access decisions are continuously evaluated using identity, authentication state, device posture, authorization, contextual information, and resource sensitivity. The scenario's emphasis on continuously validating and verifying access therefore directly describes Zero Trust.
Traditional perimeter-oriented models tend to treat internal network position as a degree of trust. Zero Trust removes that assumption and requires explicit verification before granting access to protected resources. It also supports least privilege, granular authorization, segmentation, and ongoing assessment of sessions or identities.
Secure access service edge combines networking and security capabilities delivered through a distributed service architecture and can support Zero Trust implementations, but SASE itself is not the fundamental principle described. A next-generation firewall provides application-aware traffic inspection and policy enforcement but does not by itself establish continuous identity-centric verification. Privileged access management specifically controls elevated or administrative accounts; it is an important component of access security but addresses a narrower scope than Zero Trust.
The CS0-004 objectives explicitly identify Zero Trust Network Architecture , SASE, hybrid cloud, IAM, PAM, authentication, and authorization as Security Operations architecture concepts.
Study Guide Reference: Security Operations # Network Architecture # Zero Trust Network Architecture # IAM # Authentication and Authorization # Least Privilege.

質問 # 97
There is an alert coming from the security information and event management system. Which of the following is the first task an analyst should complete?

A. Conduct remediation activities within the recovery phase.
B. Escalate the issue to the help desk team.
C. Perform triage activities that will identify the risk.
D. Contact the incident coordinator to communicate the vulnerability.

正解：C

解説：
The analyst must first validate and triage the alert to determine its severity, scope, and potential impact before escalating or beginning remediation.
