NEW QUESTION # 215
Which of the following key management practices ensures that an encryption key is maintained within the organization?
Answer: D
Explanation:
Step by Step Explanation:
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 thebest 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: HSMs are a core component of strong key management practices, often discussed in CASP+ material related to cryptography and data protection.
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.
Reference: Key escrow is sometimes used for data recovery, but it's generally not recommended for maintaining the highest level of security and control over encryption keys. This is relevant to CASP+ discussions on risk assessment and key management best practices.
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 LifecycleManagement: 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.
In conclusion, using an on-premises HSM for key storage is the best way to ensure that an organization maintains control over its encryption keys. It provides the highest level of security and control, aligning with best practices in cryptography and key management as emphasized in the CASP+ exam objectives.
NEW QUESTION # 216
A company is rewriting a vulnerable application and adding the mprotect()system call in multiple parts of the application's code that was being leveraged by a recent exploitation tool.
Which of the following should be enabled to ensure the application can leverage the new system call against similar attacks in the future?
Answer: D
Explanation:
The NX bit (No eXecute bit) is a security feature that marks certain areas of memory as non- executable. This prevents code from being run in those areas, which is a common technique used in modern operating systems to protect against buffer overflow and other exploits. When the application leverages the mprotect() system call, it can mark memory regions as non-executable, making it more difficult for attackers to execute injected malicious code. By enabling the NX bit, the system enforces that no code can be executed from areas that should only contain data, preventing certain types of exploits.
NEW QUESTION # 217
A company is developing a new service product offering that will involve the Security Officer (CISO) researching the relevant compliance regulations. Which of the following best describes the CISO's action?
Answer: B
Explanation:
Comprehensive and Detailed Step-by-Step
Option A: Data retention
Data retention refers to the policies and procedures surrounding how long data must be retained to meet regulatory, operational, or business requirements.
This does not describe the CISO's research into compliance regulations.
Option B: Data classification
Data classification involves categorizing data based on its sensitivity or importance (e.g., public, confidential, restricted).
While this is a critical process for compliance, it does not describe researching regulations.
Option C: Due diligence
Correct Answer.
Due diligence is the process of conducting thorough research and analysis to ensure that a company's operations comply with applicable laws, standards, and best practices.
The CISO's action of researching relevant compliance regulations directly aligns with due diligence responsibilities.
This concept is emphasized in the CASP+ objectives under governance, risk, and compliance (GRC), highlighting the need for security leaders to verify compliance requirements during product or service development.
Option D: Reference framework
A reference framework provides guidelines or standards, such as ISO 27001 or NIST frameworks, for structuring security programs.
While the CISO may use a framework during this process, the act of researching regulations is not equivalent to referencing a framework.
Reference:
CompTIA CASP+ Study Guide (Current Edition) - Chapters on GRC and Legal Compliance.
CASP+ Objective 3.2: Integrate enterprise resilience.
NEW QUESTION # 218
A hospital provides tablets to its medical staff to enable them to more quickly access and edit patients' charts. The hospital wants to ensure that if a tablet is Identified as lost or stolen and a remote command is issued, the risk of data loss can be mitigated within seconds. The tablets are configured as follows to meet hospital policy:
- Full disk encryption is enabled
- "Always On" corporate VPN is enabled
- ef-use-backed keystore is enabled'ready.
- Wi-Fi 6 is configured with SAE.
- Location services is disabled.
- Application allow list is configured
Answer: C
Explanation:
To mitigate the risk of data loss on a lost or stolen tablet quickly, the most effective strategy is to return the device's solid-state media to zero, which effectively erases all data on the device.
Immediate Data Erasure: Returning the solid-state media to zero ensures that all data is wiped instantly, mitigating the risk of data loss if the device is lost or stolen.
Full Disk Encryption: Even though the tablets are already encrypted, physically erasing the data ensures that no residual data can be accessed if someone attempts to bypass encryption.
Compliance and Security: This method adheres to best practices for data security and compliance, ensuring that sensitive patient data cannot be accessed by unauthorized parties.
NEW QUESTION # 219
A security operations engineer needs to prevent inadvertent data disclosure when encrypted SSDs are reused within an enterprise. Which of the following is the most secure way to achieve this goal?
Answer: B
Explanation:
The most secure way to prevent inadvertent data disclosure when encrypted SSDs are reused is to securely delete the encryption keys used by the SSD. Without the encryption keys, the data on the SSD remains encrypted and is effectively unreadable, rendering any residual data useless. This method is more reliable and efficient than overwriting data multiple times or using other physical destruction methods.
