DoD Directive 8570.01 Certification Requirements
DoD 8570 requires two certifications for compliance, an approved IA certification based on your assigned IAT level and a Computing Environment (CE) certification based on the equipment and software you work with for your primary duties. The DoD 8570 Information Assurance Workforce Improvement Program website has a good FAQ section that answers many questions regarding the requirements. The specific FAR clause for contractors, which references the requirement, is displayed below along with direct links to the DoD source.

"C220.127.116.11.3. In addition to the IA baseline certification requirement for their level, IATs with privileged access must obtain appropriate Computing Environment (CE) certifications for the operating system(s) and/or security related tools/devices they support as required by their employing organization. If supporting multiple tools and devices, an IAT should obtain CE certifications for all the tools and devices they are supporting. At a minimum the IAT should obtain a certification for the tool or device he or she spends the most time supporting. For example, if an IAT is spending most of his or her time supporting security functions on a CISCO router, the IAT should obtain a CE certification for that equipment."
