Question 361

Which of the following features of a library control software package would protect against unauthorized updating of source code?

    Correct Answer: A

    Access controls for source libraries are the most effective mechanism for preventing unauthorized updates to source code. They restrict who can access and modify the source code, ensuring that only authorized personnel can make changes. This directly protects against unauthorized modifications. Other features like date and time stamping and required approvals are useful for tracking and auditing changes but do not inherently prevent unauthorized access.

Discussion
ChangwhaOption: A

A. Access controls for source libraries

SwallowsOption: A

While date and time stamping of source and object code (Option B) can provide valuable information about when changes were made to the code, it does not inherently prevent unauthorized updates. Timestamps can help track changes and identify potential discrepancies, but they do not restrict access or prevent unauthorized modifications on their own.
