最新的 Cybersecurity Audit CCOA 免費考試真題 (Q130-Q135):

問題 #130
When reviewing encryption applied to data within an organization's databases, a cybersecurity analyst notices that some databases use the encryption algorithms SHA-1 or 3-DES while others use AES-256. Which algorithm should the analyst recommend be used?

• A. TLS 1.1
• B. DES
• C. AES-256
• D. SHA-1

答案：C

解題說明：
AES-256 (Advanced Encryption Standard)is the recommended algorithm for encrypting data within databases because:
* Strong Encryption:Uses a 256-bit key, providing robust protection against brute-force attacks.
* Widely Adopted:Standardized and approved for government and industry use.
* Security Advantage:AES-256 is significantly more secure compared to older algorithms like3-DESor SHA-1.
* Performance:Efficient encryption and decryption, suitable for database encryption.
Incorrect Options:
* B. TLS 1.1:Protocol for secure communications, not specifically for data encryption within databases.
* C. SHA-1:A hashing algorithm, not suitable for encryption (also considered broken and insecure).
* D. DES:An outdated encryption standard with known vulnerabilities.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 6, Section "Encryption Standards," Subsection "Recommended Algorithms" - AES-256 is the preferred algorithm for data encryption due to its security and efficiency.

 

問題 #131
Which of the following is theMOSTimportant component oftheasset decommissioning process from a data risk perspective?

• A. Informing the data owner when decommissioning is complete
• B. Updating the asset status in the configuration management database (CMD8)
• C. Destruction of data on the assets
• D. Removing the monitoring of the assets

答案：C

解題說明：
Themost important component of asset decommissioningfrom adata risk perspectiveis thesecure destruction of dataon the asset.
* Data Sanitization:Ensures that all sensitive information is irretrievably erased before disposal or repurposing.
* Techniques:Physical destruction, secure wiping, or degaussing depending on the storage medium.
* Risk Mitigation:Prevents data leakage if the asset falls into unauthorized hands.
Incorrect Options:
* A. Informing the data owner:Important but secondary to data destruction.
* C. Updating the CMDB:Administrative task, not directly related to data risk.
* D. Removing monitoring:Important for system management but not the primary risk factor.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 9, Section "Asset Decommissioning," Subsection "Data Sanitization Best Practices" - Data destruction is the most critical step to mitigate risks.

 

問題 #132
What is the GREATEST security concern associated with virtual (nation technology?

• A. Shared network access
• B. Insufficient isolation between virtual machines (VMs)
• C. Missing patch management for the technology
• D. Inadequate resource allocation

答案：B

解題說明：
The greatest security concern associated withvirtualization technologyis theinsufficient isolation between VMs.
* VM Escape:An attacker can break out of a compromised VM to access the host or other VMs on the same hypervisor.
* Shared Resources:Hypervisors manage multiple VMs on the same hardware, making it critical to maintain strong isolation.
* Hypervisor Vulnerabilities:A flaw in the hypervisor can compromise all hosted VMs.
* Side-Channel Attacks:Attackers can exploit shared CPU cache to leak information between VMs.
Incorrect Options:
* A. Inadequate resource allocation:A performance issue, not a primary security risk.
* C. Shared network access:Can be managed with proper network segmentation and VLANs.
* D. Missing patch management:While important, it is not unique to virtualization.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 6, Section "Virtualization Security," Subsection "Risks and Threats" - Insufficient VM isolation is a critical concern in virtual environments.

 

問題 #133
An organization uses containerization for its business application deployments, and all containers run on the same host, so they MUST share the same:

• A. database.
• B. operating system.
• C. user data.
• D. application.

答案：B

解題說明：
In acontainerization environment, all containers running on thesame hostshare thesame operating system kernelbecause:
* Container Architecture:Containers virtualize at the OS level, unlike VMs, which have separate OS instances.
* Shared Kernel:The host OS kernel is shared across all containers, which makes container deployment lightweight and efficient.
* Isolation through Namespaces:While processes are isolated, the underlying OS remains the same.
* Docker Example:A Docker host running Linux containers will only support other Linux-based containers, as they share the Linux kernel.
Other options analysis:
* A. User data:Containers may share volumes, but this is configurable and not a strict requirement.
* B. Database:Containers can connect to the same database but don't necessarily share one.
* D. Application:Containers can run different applications even when sharing the same host.
CCOA Official Review Manual, 1st Edition References:
* Chapter 10: Secure DevOps and Containerization:Discusses container architecture and kernel sharing.
* Chapter 9: Secure Systems Configuration:Explains how container environments differ from virtual machines.
