質問 # 220
Which of the following key management practices ensures that an encryption key is maintained within the organization?
正解：A
解説：
Comprehensive and Detailed Step by Step
Understanding the Scenario: The question is about ensuring that an organization retains control over its encryption keys. It focuses on different key storage and management methods.
Analyzing the Answer Choices:
A . Encrypting using a key stored in an on-premises hardware security module (HSM): This is the best option for maintaining complete control over encryption keys. An HSM is a dedicated, tamper-resistant hardware device specifically designed for secure key storage and cryptographic operations. Storing keys on-premises within an HSM ensures the organization has exclusive access.
Reference:
B . Encrypting using server-side encryption capabilities provided by the cloud provider: With server-side encryption, the cloud provider typically manages the encryption keys. This means the organization is relinquishing some control over the keys.
C . Encrypting using encryption and key storage systems provided by the cloud provider: Similar to option B, using cloud-provider-managed key storage systems means the organization doesn't have full, exclusive control over the keys.
D . Encrypting using a key escrow process for storage of the encryption key: Key escrow involves entrusting a third party with a copy of the encryption key. This introduces a potential security risk, as the organization no longer has sole control over the key. Also, the key is not maintained within the organization.
Why A is the Correct answer:
Control: On-premises HSMs provide the highest level of control over encryption keys. The organization has physical and logical control over the HSM and the keys stored within it.
Security: HSMs are designed to be tamper-resistant and protect keys from unauthorized access, even if the surrounding systems are compromised.
Compliance: In some industries, regulatory requirements may mandate that organizations maintain direct control over their encryption keys. On-premises HSMs can help meet these requirements.
CASP+ Relevance: HSMs, key management, and data encryption are fundamental topics in CASP+. The exam emphasizes understanding the security implications of different key management approaches.
Elaboration on Key Management Principles:
Key Lifecycle Management: Proper key management involves managing the entire lifecycle of a key, from generation and storage to rotation and destruction.
Separation of Duties: It's generally a good practice to separate the roles of key management and data encryption to enhance security.
Access Control: Strict access controls should be in place to limit who can access and use encryption keys.
質問 # 221
A software vendor provides routine functionality and security updates to its global customer base. The vendor would like to ensure distributed updates are authorized, originate from only the company, and have not been modified by others. Which of the following solutions best supports these objectives?
正解：D
解説：
Comprehensive and Detailed
Code signing uses cryptographic digital signatures to prove that software or updates come from a trusted source and have not been altered. In the SecurityX CAS-005 objectives, this is covered under security engineering and cryptographic assurance mechanisms.
Envelope encryption protects confidentiality but does not authenticate the source.
File integrity monitoring detects file changes but does not confirm the origin of the update.
Application control manages which software can run but does not ensure authenticity of distributed files.
Only code signing meets all three objectives: verifying the source, ensuring authorization, and proving integrity.
質問 # 222
An analyst reviews a SIEM and generates the following report:
OnlyHOST002is authorized for internet traffic. Which of the following statements is accurate?
正解：C
解説：
Understanding the Security Event:
HOST002 is the only device authorized for internet traffic. However, theSIEM logs show that VM002 is making network connections to web.corp.local.
This indicatesunauthorized access, which could bea sign of lateral movement or network infection.
This is ared flagfor potential malware, unauthorized software, or a compromised host.
Why Option D is Correct:
Unusual network traffic patternsare often an indicator of acompromised system.
VM002 should not be communicating externally, but it is.
This suggests a possiblebreach or malware infectionattempting to communicate with a command-and-control (C2) server.
Why Other Options Are Incorrect:
A (Misconfiguration):While a misconfiguration could explain the unauthorized connections, the pattern of activity suggests something more malicious.
B (Security incident on HOST002):The issue is not with HOST002. The suspicious activity isfrom VM002.
C (False positives):The repeated pattern of unauthorized connections makes false positivesunlikely.

質問 # 223
An organization found a significant vulnerability associated with a commonly used package in a variety of operating systems. The organization develops a registry of software dependencies to facilitate incident response activities. As part of the registry, the organization creates hashes of packages that have been formally vetted. Which of the following attack vectors does this registry address?
正解：B
解説：
Why A is the Correct answer:
A supply chain attack is exactly what the organization is trying to mitigate. By creating a registry of known-good software packages and their hashes, they can verify that the packages they are using are legitimate and haven't been altered.
If an attacker were to compromise a software package in the supply chain, the hash of the altered package would not match the hash in the organization's registry. This would immediately alert the organization to a potential compromise.
CASP+ Relevance: This aligns with the CASP+ exam objectives, which emphasize the importance of risk management, threat intelligence, and implementing security controls to address various attack vectors, including supply chain risks.
How the Registry Works (Elaboration based on CASP+ principles):
Hashing: When a package is vetted, a cryptographic hash function (like SHA-256) is used to generate a unique "fingerprint" (the hash) of the package's contents.
Verification: Before installing or using a package, its hash is calculated and compared to the hash stored in the registry. A match confirms the package's integrity. A mismatch indicates tampering.
Incident Response: If a vulnerability is discovered in a commonly used package, the registry helps the organization quickly identify which systems are affected based on the dependency list and the stored hashes.
Explanation:
Comprehensive and Detailed Step by Step
Understanding the Scenario: The question describes a proactive security measure where an organization maintains a registry of software dependencies and their corresponding hashes. This registry is used to verify the integrity of software packages.
Analyzing the Answer Choices:
A . Supply chain attack: This type of attack involves compromising the software supply chain by injecting malicious code into legitimate software packages.
Reference:
B . Cipher substitution attack: This is a cryptographic attack focused on replacing ciphertext with a different ciphertext to deduce the key. It's not relevant to the scenario.
C Side-channel analysis: This attack involves gathering information from the physical implementation of a system (e.g., timing, power consumption) rather than exploiting the algorithm itself. It's not applicable here.
D . On-path attack (formerly man-in-the-middle): This attack involves intercepting and potentially altering communication between two parties. While important, it's not the primary focus of the registry.
質問 # 224
A company wants to improve and automate the compliance of its cloud environments to meet industry standards. Which of the following resources should the company use to best achieve this goal?
正解：C
解説：
Comprehensive and Detailed Explanation:
Automating compliance in cloud environments requires a tool that can enforce configurations, manage infrastructure as code, and align with industry standards (e.g., NIST, ISO). Let's evaluate:
* A. Jenkins:A CI/CD tool for automating software builds and deployments. It's not designed for compliance enforcement or infrastructure management.
* B. Python:A programming language that can be scripted for automation but lacks built-in compliance- focused features without significant custom development.
* C. Ansible:An automation tool for configuration management, application deployment, and compliance enforcement. It uses playbooks to define desired states, making it ideal for automating compliance checks and remediation in cloud environments (e.g., AWS, Azure). CAS-005 emphasizes automation tools for security and compliance, and Ansible fits perfectly.
