Final answer:
Parallel controls in technology are used as a risk management strategy to ensure that modifications to existing programs are correct and do not introduce new issues, which makes the statement true.
Step-by-step explanation:
The statement "Controls parallel are to provide reasonable assurances regarding modifications to existing programs" is generally true. In the context of information systems and technology, 'parallel controls' typically refer to mechanisms in place that run and check new or modified software alongside the old version to ensure the new modifications are producing the correct results before completely transitioning to the new system.
This is a risk management strategy that provides an additional layer of assurance that the updated or new program functions correctly and does not introduce new errors or vulnerabilities into the system.
