CAS-005 Exam Dumps : CompTIA SecurityX Certification Exam

The best location to test a newly released feature for an internal application, without affecting the production environment, is the staging environment. Here’s a detailed explanation:

Staging Environment: This environment closely mirrors the production environment in terms of hardware, software, configurations, and settings. It serves as a final testing ground before deploying changes to production. Testing in the staging environment ensures that the new feature will behave as expected in the actual production setup.

Isolation from Production: The staging environment is isolated from production, which means any issues arising from the new feature will not impact the live users or the integrity of the production data. This aligns with best practices in change management and risk mitigation.

Realistic Testing: Since the staging environment replicates the production environment, it provides realistic testing conditions. This helps in identifying potential issues that might not be apparent in a development or testing environment, which often have different configurations and workloads.

Comprehensive and Detailed Step-by-Step Explanation:

Option A: Deny list

Deny lists block specific applications or processes identified as malicious.

This approach is reactive and may inadvertently block the non-standard applications that are currently in use without proper ownership.

Option B: Allow list

Allow lists permit only pre-approved applications to run.

While secure, this approach requires defining all non-standard applications, which may disrupt operations in an environment where ownership is unclear.

Option C: Audit mode

Correct Answer.

Audit mode allows monitoring and logging of applications without enforcing restrictions.

This is ideal in environments with non-standard applications and undefined ownership because it enables the engineer to observe the environment and gradually implement control without interruption.

Audit mode provides critical visibility into the software landscape, ensuring that necessary applications remain functional.

Option D: MAC list

Mandatory Access Control (MAC) lists restrict access based on classification and clearance levels.

This does not align with application control objectives in this context.

To improve the vulnerability management process in an environment where new devices/IPs are added and dropped regularly, the company should perform regular discovery scanning throughout the IT landscape using the vulnerability management tool. Here’s why:

Accurate Asset Inventory: Regular discovery scans help maintain an up-to-date inventory of all assets, ensuring that the vulnerability management process includes all relevant devices and IPs.

Consistency in Reporting: By continuously discovering and scanning new and existing assets, the company can generate consistent and comprehensive vulnerability reports that reflect the current state of the network.

Proactive Management: Regular scans enable the organization to proactively identify and address vulnerabilities on new and existing assets, reducing the window of exposure to potential threats.
