A company has issued a new mobile device policy permitting BYOD and company-issued devices. The company-issued device has a managed middleware client that restricts the applications allowed on company devices and provides those that are approved. The middleware client provides configuration standardization for both company owned and BYOD to secure data and communication to the device according to industry best practices. The policy states that, “BYOD clients must meet the company’s infrastructure requirements to permit a connection.” The company also issues a memorandum separate from the policy, which provides instructions for the purchase, installation, and use of the middleware client on BYOD. Which of the following is being described?
A. Asset management
B. IT governance
C. Change management
D. Transference of risk
Answer: B

The internal website is hosted on a laptop on the internal corporate network. The internal network does not restrict traffic between any internal hosts. Which of the following locations will BEST secure both the intranet and the customer facing website?
A. The existing internal network segment
B. Dedicated DMZ network segments
C. The existing extranet network segment

Q226. - (Topic 3)
The Chief Technology Officer (CTO) has decided that servers in the company datacenter should be virtualized to conserve physical space. The risk assurance officer is concerned that the project team in charge of virtualizing servers plans to co-mingle many guest operating systems with different security requirements to speed up the rollout and reduce the number of host operating systems or hypervisors required.
Which of the following BEST describes the risk assurance officer’s concerns?
A. Co-mingling guest operating system with different security requirements allows guest OS privilege elevation to occur within the guest OS via shared memory allocation with the host OS.
B. Co-mingling of guest operating systems with different security requirements increases the risk of data loss if the hypervisor fails.
C. A weakly protected guest OS combined with a host OS exploit increases the chance of a successful VMEscape attack being executed, compromising the hypervisor and other guest OS.
D. A weakly protected host OS will allow the hypervisor to become corrupted resulting in data throughput performance issues.
Answer: C
