NEW QUESTION # 78
Which of the following is the core component of an operating system that manages resources, implements security policies, and provides the interface between hardware and software?
Answer: B
Explanation:
Thekernelis the core component of an operating system (OS) responsible for:
* Resource Management:Manages CPU, memory, I/O devices, and other hardware resources.
* Security Policies:Enforces access control, user permissions, and process isolation.
* Hardware Abstraction:Acts as an intermediary between the hardware and software, providing low- level device drivers.
* Process and Memory Management:Handles process scheduling, memory allocation, and inter-process communication.
Incorrect Options:
* B. Library:A collection of functions or routines that can be used by applications, not the core of the OS.
* C. Application:Runs on top of the OS, not a part of its core functionality.
* D. Shell:An interface for users to interact with the OS, but not responsible for resource management.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 4, Section "Operating System Security," Subsection "Kernel Responsibilities" - The kernel is fundamental to managing system resources and enforcing security.
NEW QUESTION # 79
After an organization's financial system was moved to a cloud-hosted solution that allows single sign-on (SSO) for authentication purposes, data was compromised by an individual logged onto the local network using a compromised username and password. What authentication control would have MOST effectively prevented this situation?
Answer: D
Explanation:
Multi-factor authentication (MFA)would have been the most effective control to prevent data compromise in this scenario:
* Enhanced Security:MFA requires multiple authentication factors, such as a password (something you know) and a one-time code (something you have).
* Mitigates Credential Theft:Even if a username and password are compromised, an attacker would still need the second factor to gain access.
* SSO Integration:MFA can be seamlessly integrated with SSO to ensure robust identity verification.
* Example:A user logs in with a password and then confirms their identity using an authenticator app.
Incorrect Options:
* A. Challenge handshake:An outdated protocol for authentication, not as secure as MFA.
* C. Token-based:Often used as part of MFA but alone does not mitigate password theft.
* D. Single-factor:Only uses one method (e.g., a password), which is insufficient to protect against credential compromise.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 4, Section "Identity and Access Management," Subsection "Multi-Factor Authentication" - MFA is essential to prevent unauthorized access when credentials are compromised.
NEW QUESTION # 80
Which of (he following is the PRIMARY reason to regularly review firewall rules?
Answer: B
Explanation:
Regularly reviewing firewall rules ensures that outdated, redundant, or overly permissive rules are identified and removed.
* Reduced Attack Surface:Unnecessary or outdated rules may open attack vectors.
* Compliance and Policy Adherence:Ensures that only authorized communication paths are maintained.
* Performance Optimization:Reducing rule clutter improves processing efficiency.
* Minimizing Misconfigurations:Prevents rule conflicts or overlaps that could compromise security.
Incorrect Options:
* B. Identifying blocked traffic to permit:The review's primary goal is not to enable traffic but to reduce unnecessary rules.
* C. Ensuring correct rule order:While important, this is secondary to identifying obsolete rules.
* D. Correcting administrator mistakes:Though helpful, this is not the main purpose of regular reviews.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 5, Section "Firewall Management," Subsection "Rule Review Process" - The primary reason for reviewing firewall rules regularly is to eliminate rules that are no longer necessary.
NEW QUESTION # 81
A penetration tester has been hired and given access to all code, diagrams,and documentation. Which type oftesting is being conducted?
Answer: D
Explanation:
The scenario describes apenetration testing approachwhere the tester is givenaccess to all code, diagrams, and documentation, which is indicative of aFull Knowledge(also known asWhite Box) testing methodology.
* Characteristics:
* Comprehensive Access:The tester has complete information about the system, including source code, network architecture, and configurations.
* Efficiency:Since the tester knows the environment, they can directly focus on finding vulnerabilities without spending time on reconnaissance.
* Simulates Insider Threats:Mimics the perspective of an insider or a trusted attacker with full access.
* Purpose:To thoroughly assess the security posture from aninformed perspectiveand identify vulnerabilities efficiently.
Other options analysis:
* B. Unlimited scope:Scope typically refers to the range of testing activities, not the knowledge level.
* C. No knowledge:This describesBlack Boxtesting where no prior information is given.
* D. Partial knowledge:This would beGray Boxtesting, where some information is provided.
CCOA Official Review Manual, 1st Edition References:
* Chapter 8: Penetration Testing Methodologies:Differentiates between full, partial, and no- knowledge testing approaches.
* Chapter 9: Security Assessment Techniques:Discusses how white-box testing leverages complete information for in-depth analysis.
NEW QUESTION # 82
What is the GREATEST security concern associated with virtual (nation technology?
Answer: A
Explanation:
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.
