A security engineer has inherited an authentication project which integrates 1024-bit PKI
certificates into the company infrastructure and now has a new requirement to integrate 2048-bit
PKI certificates so that the entire company will be interoperable with its vendors when the project
is completed. The project is now 25% complete, with 15% of the company staff being issued 1024-
bit certificates. The provisioning of network based accounts has not occurred yet due to other
project delays. The project is now expected to be over budget and behind its original schedule.
Termination of the existing project and beginning a new project is a consideration because of the
change in scope. Which of the following is the security engineer’s MOST serious concern with
implementing this solution?

A.
Succession planning

B.
Performance

C.
Maintainability

D.
