How often should access reviews be performed for OIMS, and who should conduct them?

• A. Weekly
• B. Monthly
• C. Regularly (quarterly or biannually); by security/compliance team with system owners
• D. Never

Answer: (C)

Regular, periodic access reviews are essential in OIMS to ensure that only authorized users retain access and that privileges match current roles. The best practice is to perform these reviews on a cadence like quarterly or biannually to balance timely detection of access drift with workable administrative load. They should be conducted by the security/compliance team with involvement from system owners, so governance and policy requirements are enforced while the actual need for access is validated against job duties. This collaboration helps promptly revoke unused or unnecessary access and adjust permissions as roles change, preserving confidentiality and data integrity for sensitive offender information. Weekly or monthly reviews are typically excessive for most environments, and never reviewing access leaves the system exposed to unnecessary risk.
