CJIS compliance refers to adhering to the security requirements set by the FBI Criminal Justice Information Services Advisory Policy Board (CJIS APB) to protect criminal justice information (CJI). It establishes the minimum controls necessary to safeguard CJI throughout its lifecycle, whether at rest or in transit. Compliance is crucial for agencies that access CJI databases, ensuring that sensitive information remains secure and that personnel can operate effectively in the field.

BYOD policies are not recommended for accessing CJI because they pose significant challenges in managing secure device configurations. The technical methods required for CJIS compliance often exceed any potential cost savings from implementing BYOD. Additionally, it can be difficult to apply effective security measures on personal devices, which may lead to unauthorized access to sensitive information.

MDM is essential for CJIS compliance as it allows agencies to maintain control over mobile devices accessing CJI. CJIS Policy mandates the use of MDM to perform tasks such as remote locking or wiping devices, enforcing encryption, and detecting unauthorized configurations. This level of control helps mitigate security risks associated with mobile devices, ensuring that only authorized personnel can access sensitive information.
