Computer Crimes Unit Network (CCUNet)

In its mission to ensure a safe, efficient, accessible, and convenient transportation system that meets our vital national interests and enhances the quality of life, OIG collects, accesses, and uses significant amounts of data every day. With increased data collection comes increased privacy risk to DOT employees, contractors, and members of the public.  The OIG is committed to protecting the integrity and confidentiality of all data throughout all its component systems.

This purpose of this privacy impact assessment is to proactively document the risk management framework associated with the DOT/OIG Data Analytics and Computer Crimes Unit (DACC) Network (CCUNet) to ensure privacy of all data managed within the system. The system serves as a temporary workspace where OIG investigators can process and review evidence collected via a variety of sources such as subpoena, consent, or warrant directly supporting OIG investigations as authorized by the Inspector General Act of 1978.  Such evidence may include any form of privacy information the person or business being investigated collected or maintained in any number of electronic formats. For example, a single forensic image acquired during a search warrant of a business may contain a database of personal information for customers of the business or detailed employee information. Since the scope of such evidence is very broad, the OIG DACC takes extreme precautions above and beyond what is mandated by federal regulations to ensure the privacy of the information is maintained.  

DOT is committed to ensuring that information is available in appropriate alternative formats to meet the requirements of persons who have a disability. If you require an alternative version of files provided on this page, please contact
