CAS-005 Exam Dumps - CompTIA SecurityX Certification Exam

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.

A proxy-based Cloud Access Security Broker (CASB) is chosen primarily for its ability to block unapproved applications and services. Here’s why:

Application and Service Control: Proxy-based CASBs can monitor and control the use of applications and services by inspecting traffic as it passes through the proxy. This allows the organization to enforce policies that block unapproved applications and services, ensuring compliance with security policies.

Visibility and Monitoring: By routing traffic through the proxy, the CASB can provide detailed visibility into user activities and data flows, enabling better monitoring and threat detection.

Real-Time Protection: Proxy-based CASBs can provide real-time protection against threats by analyzing and controlling traffic before it reaches the end user, thus preventing the use of risky applications and services.

This scenario describes an attack where the attacker mimics the CEO’s voice to deceive the CFO, likely using AI-generated audio. According to the CompTIA SecurityX CAS-005 study guide (Domain 1: Security Strategy and Risk Management, 1.2), a deepfake attack involves using artificial intelligence to create realistic but fake audio, video, or other media to impersonate someone. In this case, the voice similarity suggests a deepfake audio attack, which is a targeted social engineering tactic.

Option A:Smishing involves SMS-based phishing, not voicecalls.

Option C:Automated exploit generation refers to creating software exploits, not impersonation.

Option D:Spear phishing targets specific individuals but typically via email, not voice-based impersonation.

Option B:Deepfake is the most accurate, as it describes AI-driven impersonation of the CEO’s voice.

SecurityX CAS-005 cloud architecture guidance emphasizes horizontal scaling for workloads that need to handle both predictable and fluctuating growth over time. Horizontal scaling allows the infrastructure to add nodes for both compute and storage dynamically, providing elasticity to meet fluctuating computational demands while accommodating exponential storage growth.

Vertical scaling (B) has hardware limits and is not as flexible for large, sustained growth.

CDN (A) is optimized for content distribution, not intensive compute workloads.

Load balancing (C) distributes workloads but does not address scaling for data growth.

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.

The best solution is Conditional Access (D). Conditional access policies enforce access requirements based on contextual signals such as device compliance, user identity, location, or risk profile. In this case, the administrator can configure conditional access to ensure that only managed, corporate-approved devices are allowed to access confidential data. If an employee attempts to use a personal laptop, the access request will be blocked or redirected to a secure process (e.g., virtual desktop).

Option A (OCSP stapling) relates to certificate revocation checking and does not control device access. Option B (CASB) provides cloud access visibility and control but is broader and less precise than enforcing direct device-level conditional policies. Option C (SOAR) orchestrates responses but is not primarily designed for access enforcement. Option E (package monitoring) detects software changes but does not prevent unauthorized device usage.

Conditional access is a core principle in Zero Trust and modern IAM, making it the best solution for ensuring that sensitive data can only be accessed from trusted devices.

The application allows users to input URLs, which the application then fetches using requests.get(url). This functionality can be exploited if not properly validated, leading to potential security vulnerabilities such as Server-Side Request Forgery (SSRF).

Implementing a code scanner as part of the development pipeline can help identify insecure coding practices, such as unsanitized user inputs and improper handling of external requests. Code scanners analyze the source code for known vulnerabilities and coding errors, enabling developers to remediate issues before deployment.
