CompTIA Updated CAS-005 Exam Questions and Answers by fearne

To prevent sensitive corporate information from being exposed if a laptop is stolen, the solution must ensure that data is not stored locally and access is tightly controlled. According to the CompTIA SecurityX CAS-005 study guide (Domain 4: Governance, Risk, and Compliance, 4.3), Desktop as a Service (DaaS) hosts data and applications in the cloud, reducing the risk of data exposure on physical devices. Combining DaaS with multifactor authentication (MFA) ensures that even if a laptop is stolen, unauthorized access to the cloud environment is prevented.

Option B:IP allow lists and SSO do not address data stored locally on the laptop, which could be accessed offline.

Option C:MDM and stronger passwords help but do not prevent data exposure if the device is compromised (e.g., via offline attacks).

Option D:Updating policies and monitoring breaches are reactive measures that do not directly protect data on a stolen laptop.

Option A:DaaS ensures no sensitive data resides on the device, and MFA secures access, making it the best solution.

A risk register is atool commonly used in risk management to document all identified risks, their assessment in terms of likelihood and impact, and the actions steps to manage them. By adding the newly identified risks to the risk register and assigning an owner and severity, the organization ensures that each risk is visible to stakeholders and has a designated individual responsible for its management. This aligns with the company's requirements for transparency and accountability in risk management.​

Vendor lock-in occurs when a client is overly dependent on a vendor, limiting flexibility. Risks include:

Option B:Vendors changing offerings (e.g., features, pricing) can disrupt the client, a key lock-in risk.

Option D:Decreased quality of service may result from reliance on a single vendor without alternatives.

Option A:Seamless data movement is a benefit, not a risk.

Option C:Sufficient service is neutral or positive, not a risk.

Option E:Multicloud is hindered by lock-in, not a risk of it.

Option F:Increased interoperability contradicts lock-in’s limitations.

To determine how the acquisition of Company B will impact the attack surface, the following steps are crucial:

A. Documenting third-party connections used by Company B: Understanding all external connections is essential for assessing potential entry points for attackers and ensuring that these connections are secure.

E. Performing an architectural review of Company B's network: This review will identify vulnerabilities and assess the security posture of the acquired company's network, providing a comprehensive understanding of the new attack surface.

These actions will provide a clear picture of the security implications of the acquisition and help in developing a plan to mitigate any identified risks.
