CompTIA Cybersecurity Analyst (CySA+) Certification Exam 認定 CS0-004 試験問題 (Q181-Q186):

質問 # 181
Which of the following best explains why sensitive data should be encrypted at rest on laptops?

正解：B

解説：
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.


質問 # 182
Which of the following is the most important component to include in the preparation phase of an incident response plan?

正解：C

解説：
Clearly defined roles and responsibilities are foundational to incident-response preparation because responders must know in advance who has authority to make decisions and who performs specific technical, management, legal, communications, and recovery functions. Attempting to determine ownership while an active compromise is developing introduces delays, duplicated effort, communication failures, and potentially conflicting actions.
Preparation should define escalation paths, decision-making authority, contact mechanisms, incident leadership, technical responsibilities, evidence-management responsibilities, and coordination with business, legal, privacy, communications, and external parties where applicable. NIST's current incident-response guidance emphasizes preparation across organizational risk-management activities so organizations can respond and recover efficiently when incidents occur.
An after-action report is produced after an incident and documents the event, response actions, recovery, and lessons learned. Data-integrity validation is important during evidence analysis and recovery but is not the primary organizational foundation of preparation. Chain of custody must be established when evidence is collected and transferred, particularly where legal proceedings may occur, but it represents one procedure within a broader incident-response capability.
Without predefined ownership, even technically sound procedures may fail operationally.
Study Guide Reference: Incident Response and Management # Preparation # Incident Response Plan # Roles and Responsibilities # Escalation # Communication # Authority and Coordination.


質問 # 183
A server was recently compromised. A security analyst needs to collect artifacts for further analysis before disconnecting the server from the network.
Which of the following artifacts should the analyst collect first?

正解：C

解説：
The analyst should collect the Netstat output first because current network-connection information is highly volatile and will change immediately when the server is disconnected. netstat-type evidence can identify active TCP/UDP connections, listening services, remote endpoints, and potentially the communication channels associated with an attacker or command-and-control infrastructure.
Digital-forensic acquisition follows the order of volatility : evidence most likely to disappear or change should be captured before more persistent artifacts. RFC 3227 explicitly directs investigators to proceed from volatile to less-volatile evidence and identifies information such as routing data, ARP cache, process state, memory-related information, and network state as highly time-sensitive.
The ARP table is also volatile and should be captured early, but the wording "before disconnecting the server from the network" makes active connection state particularly important because those sessions will terminate when network connectivity is removed. ShellBags are persistent forensic artifacts stored within Windows Registry data and can be collected later from disk. A hard-disk image is critical but comparatively nonvolatile and should follow acquisition of live state.
Therefore, live network-session information takes priority.
Study Guide Reference: Incident Response and Management # Evidence Acquisition # Order of Volatility # Live Response # netstat # Network Connections # Forensic Preservation.


質問 # 184
Which of the following security controls should be classified as operational?

正解：D

解説：
Operational controls are implemented through people and processes rather than technology alone. Conducting a penetration test is an operational control because it is a security activity performed by personnel to assess the effectiveness of security measures and identify vulnerabilities in the environment.


質問 # 185
Which of the following is an example of the shift-left concept as it pertains to the SDLC?

正解：C

解説：
Shift-left emphasizes integrating security activities as early as possible in the Software Development Life Cycle (SDLC). Scanning code for exposed API keys when it is committed to the development repository identifies security issues during development, allowing them to be remediated before reaching later testing or production stages.
