CCOA Exam Dumps : ISACA Certified Cybersecurity Operations Analyst

Maintaining an effectiverisk management programrequiresongoing reviewbecause:

Dynamic Risk Landscape:Threats and vulnerabilities evolve, necessitating continuous reassessment.

Policy and Process Updates:Regular review ensures that risk management practices stay relevant and effective.

Performance Monitoring:Allows for the evaluation of control effectiveness and identification of areas for improvement.

Regulatory Compliance:Ensures that practices remain aligned with evolving legal and regulatory requirements.

Other options analysis:

A. Approved budget:Important for resource allocation, but not the core of continuous effectiveness.

B. Automated reporting:Supports monitoring but does not replace comprehensive reviews.

C. Monitoring regulations:Part of the review process but not the sole factor.

CCOA Official Review Manual, 1st Edition References:

Chapter 5: Risk Management Frameworks:Emphasizes the importance of continuous risk assessment.

Chapter 7: Monitoring and Auditing:Describes maintaining a dynamic risk management process.

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.

To determine the host IP of the machine vulnerable toCVE-2021-22145usingGreenbone Vulnerability Manager (GVM), follow these detailed steps:

Step 1: Access Greenbone Vulnerability Manager

OpenFirefoxon your system.

Go to the GVM login page:
