CJIS Compliance for Software Developers: Security Considerations for Law Enforcement Apps

Building software for law enforcement requires developers to think about security from the beginning of the development lifecycle.
Applications that store, process, or transmit criminal justice information may need to operate within the requirements of the FBI's CJIS Security Policy.
For developers, this means that security cannot simply be treated as a feature added after development.
Understanding the Data
The first step is understanding what the application handles.
Criminal justice information can include criminal history records, biometric information, investigative files, arrest information, and other sensitive records.
Developers should understand where this information enters the application, where it is stored, how it moves between services, and who can access it.
Authentication and Authorization
Authentication verifies the identity of a user.
Authorization determines what that user is allowed to do.
For law enforcement applications, both are important. Multi-factor authentication can provide additional protection, while role-based permissions can restrict access according to job responsibilities.
Protecting Data in Transit and at Rest
Sensitive information should be protected while stored and while moving between systems.
Developers therefore need to consider encryption across databases, APIs, communication channels, backups, and other parts of the application architecture.
Encryption should not be considered only at the database layer. The complete data flow needs to be reviewed.
Audit Logging
Applications handling sensitive information should maintain appropriate audit records.
Developers may need to design logging mechanisms that capture relevant security events without unnecessarily exposing sensitive information inside the logs themselves.
Audit data should also be protected from unauthorized modification or access.
Secure Cloud Architecture
Cloud applications introduce additional considerations.
A cloud provider may secure parts of the underlying infrastructure, but application teams remain responsible for areas such as identity management, configuration, application security, and data handling.
Developers should clearly understand where the provider's responsibility ends and the organization's responsibility begins.
Mobile Applications
Law enforcement personnel may access applications from mobile devices while working in the field.
Mobile applications therefore need appropriate authentication, secure communications, device protections, and access controls.
Developers should also consider what happens when a device is lost, stolen, or compromised.
Compliance Should Be Part of Development
CJIS requirements should be considered during architecture, development, testing, deployment, and maintenance.
Security controls that are designed into an application from the beginning are generally easier to manage than controls added after the system is already deployed.
Developers building applications for law enforcement can use this CJIS compliance guide for software as a broader reference for understanding requirements around authentication, encryption, access control, cloud systems, mobile devices, and security monitoring.
Conclusion
Developing software for law enforcement involves security requirements that extend beyond ordinary application development.
Authentication, authorization, encryption, logging, mobile security, cloud configuration, and continuous monitoring all need to be considered.
By incorporating security and compliance requirements into the development lifecycle, teams can build applications that are better prepared to protect sensitive criminal justice information.
