The lead systems architect on a software development project developed a design which is optimized for a distributed computing environment. The security architect assigned to the project has concerns about the integrity of the system, if it is deployed in a commercial cloud. Due topoor communication within the team, the security risks of the proposed design are not being given any attention. A network engineer on the project has a security background and is concerned about the overall success of the project. Which of the following is the BEST course of action for the network engineer to take?
A. Address the security concerns through the network design and security controls.
B. Implement mitigations to the security risks and address the poor communications on the team with the project manager.
C. Document mitigations to the security concerns and facilitate a meeting between the architects and the project manager.
D. Develop a proposal for an alternative architecture that does not leverage cloud computing and present it to the lead architect.

A new internal network segmentation solution will be implemented into the enterprise that consists of 200 internal firewalls. As part of running a pilot exercise, it was determined that it takes three changes to deploy a new application onto the network before it is operational. Security now has a significant affect on overall availability. Which of the following would be the FIRST process to perform as a result of these findings?
A. Lower the SLA to a more tolerable level and perform a risk assessment to see if the solution could be met by another solution. Reuse the firewall infrastructure on other projects.
B. Perform a cost benefit analysis and implement the solution as it stands as long as the risks are understood by the business owners around the availability issues. Decrease the current SLA expectations to match the new solution.
C. Engage internal auditors to perform a review of the project to determine why and how the project did not meet the security requirements. As part of the review ask them to review the control effectiveness.
D. Review to determine if control effectiveness is in line with the complexity of the solution. Determine if the requirements can be met with a simpler solution.
Answer: D

Q136. - (Topic 1)
A security manager at Company ABC, needs to perform a risk assessment of a new mobile device which the Chief Information Officer (CIO) wants to immediately deploy to all employees in the company. The product is commercially available, runs a popular mobile operating system, and can connect to IPv6 networks wirelessly. The model the CIO wants to procure also includes the upgraded 160GB solid state hard drive. The producer of the device will not reveal exact numbers but experts estimate that over 73 million of the devices have been sold worldwide. Which of the following is the BEST list of factors the security manager should consider while performing a risk assessment?
A. Ability to remotely wipe the devices, apply security controls remotely, and encrypt the SSD; the track record of the vendor in publicizing and correcting security flaws in their products; predicted costs associated with maintaining, integrating and securing the devices.
B. Ability to remotely administer the devices, apply security controls remotely, and remove the SSD; the track record of the vendor in securely implementing IPv6 with IPSec; predicted costs associated with securing the devices.
C. Ability to remotely monitor the devices, remove security controls remotely, and decrypt the SSD; the track record of the vendor in publicizing and preventing security flaws in their products; predicted costs associated with maintaining, destroying and tracking the devices.
D. Ability to remotely sanitize the devices, apply security controls locally, encrypt the SSD; the track record of the vendor in adapting the open source operating system to their platform; predicted costs associated with inventory management, maintaining, integrating and securing the devices.
