CompTIA CAS-005 Exam Dumps - Actual Questions Answers

Risk appetite is the amount of risk an organization is willing to accept to achieve its objectives. When operating with a constrained budget, understanding the organization's risk appetite is crucial because:

It helps prioritize security investments based on the level of risk the organization is willing to tolerate.

High-impact, low-likelihood events may be deemed acceptable if they fall within the organization's risk appetite, allowing for budget allocation to other critical areas.

Properly understanding and defining risk appetite ensures that limited resources are used effectively to manage risks that align with the organization's strategic goals.

The best description of the cyber threat to a central bank implementing strict risk mitigations for the hardware supply chain, including an allow list for specific countries of origin, is the risk of physical implants and tampering. Here’s why:

Supply Chain Security: The supply chain is a critical vector for hardware tampering and physical implants, which can compromise the integrity and security of hardware components before they reach the organization.

Targeted Attacks: Banks and financial institutions are high-value targets, making them susceptible to sophisticated attacks, including those involving physical implants that can be introduced during manufacturing or shipping processes.

Strict Mitigations: Implementing an allow list for specific countries aims to mitigate the risk of supply chain attacks by limiting the sources of hardware. However, the primary concern remains the introduction of malicious components through tampering.

To reduce the risk of unauthorized BYOD (Bring Your Own Device) usage, the organization should implement Conditional Access and Network Access Control (NAC).

Why Conditional Access and NAC?

Conditional Access:

User-to-Device Binding: Conditional access policies can enforce that only registered and compliant devices are allowed to access corporate resources.

Context-Aware Security: Enforces access controls based on the context of the access attempt, such as user identity, device compliance, location, and more.

Network Access Control (NAC):

Device Configuration Requirements: NAC ensures that only devices meeting specific security configurations are allowed to connect to the network.

Access Control: Provides granular control over network access, ensuring that BYOD devices comply with security policies before gaining access.

Other options, while useful, do not address the specific need to control and secure BYOD devices effectively:

A. Cloud IAM to enforce token-based MFA: Enhances authentication security but does not control device compliance.

D. PAM to enforce local password policies: Focuses on privileged account management, not BYOD control.

E. SD-WAN to enforce web content filtering: Enhances network performance and security but does not enforce BYOD device compliance.

F. DLP to enforce data protection capabilities: Protects data but does not control BYOD device access and compliance.
