A security engineer is a new member to a configuration board at the request of management. The company has two new major IT projects starting this year and wants to plan security into the application deployment. The board is primarily concerned with the applications’ compliance with federal assessment and authorization standards. The security engineer asks for a timeline to determine when a security assessment of both applications should occur and does not attend subsequent configuration board meetings. If the security engineer is only going to perform a security assessment, which of the following steps in system authorization has the security engineer omitted? (Select TWO).
A. Establish the security control baseline to be assessed
B. Build the application according to software development security standards
C. Write the systems functionality requirements into the security requirements traceability matrix
D. Review the results of user acceptance testing
E. Categorize the applications according to use
F. Consult with the stakeholders to determine which standards can be omitted

Q310. - (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
