Select the Action Items for the Appropriate Locations:

Authorization Server:

Action Item: Grant access

The authorization server's role is to authenticate the user and then issue an authorization code or token that the client application can use to access resources. Granting access involves the server authenticating the resource owner and providing the necessary tokens for the client application.

Resource Server:

Action Item: Access issued tokens

The resource server is responsible for serving the resources requested by the client application. It must verify the issued tokens from the authorization server to ensure the client has the right permissions to access the requested data.

B2B Client Application:

Action Item: Authorize access to other applications

The B2B client application must handle the OAuth flow to authorize access on behalf of the user without requiring direct knowledge of the user's credentials. This includes obtaining authorization tokens from the authorization server and using them to request access to the resource server.

Detailed Explanation:

OAuth 2.0 is designed to provide specific authorization flows for web applications, desktopapplications, mobile phones, and living room devices. The integration involves multiple steps and components, including:

Resource Owner (User):

The user owns the data and resources that are being accessed.

Client Application (B2B Client Application):

Requests access to the resources controlled by the resource owner but does not directly handle the user's credentials. Instead, it uses tokens obtained through the OAuth flow.

Authorization Server:

Handles the authentication of the resource owner and issues the access tokens to the client application upon successful authentication.

Resource Server:

Hosts the resources that the client application wants to access. It verifies the access tokens issued by the authorization server before granting access to the resources.

OAuth Workflow:

The resource owner accesses the client application.

The client application redirects the resource owner to the authorization server for authentication.

The authorization server authenticates the resource owner and asks for consent to grant access to the client application.

Upon consent, the authorization server issues an authorization code or token to the client application.

The client application uses the authorization code or token to request access to the resources from the resource server.

The resource server verifies the token with the authorization server and, if valid, grants access to the requested resources.

The CIO needs to clarify the organization’s risk appetite, which defines the level of residual risk the business is willing to accept after all mitigation measures are applied. Risk appetite reflects the balance between operational requirements, security controls, and cost constraints. In business continuity planning, risk appetite helps decision-makers determine which risks must be reduced through additional investments (e.g., redundant systems, faster recovery strategies) and which risks are tolerable based on business priorities.

Mitigation (A) refers to the strategies used to reduce risk but not the threshold of acceptable residual risk. Impact (B) and Likelihood (C) are components of risk assessment—measuring severity and probability—but they do not define acceptance criteria. Risk appetite is the guiding principle that aligns technical controls with executive tolerance for disruption or loss.

By clarifying appetite, the CIO provides the compliance team and IT leadership with a framework for designing remediation activities that ensure continuity of critical internal processes while aligning with the organization’s strategic objectives and regulatory requirements.

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.
