Which of the following tasks is performed by the same person
in a well-controlled information processing
facility/computer center?
A. Security administration and management
B. Computer operations and system development
C. System development and change management
D. System development and systems maintenance
Answer / guest
Answer: D
It is common for system development and maintenance to be
undertaken by the same person. In both cases, the programmer
requires access to the source code in the development
environment, but should not be allowed access in the
production environment. Choice A is not correct because the
roles of security administration and change management are
incompatible functions. The level of security administration
access rights could allow changes to go undetected. Computer
operations and system development (choice B) are
incompatible since it would be possible for an operator to
run a program that he/she had amended. Choice C is incorrect
because the combination of system development and change
control would allow program modifications to bypass change
control approvals.
