Per DCSA, For purposes of streamlining the onsite validation of a system, DCSA will use the DISA STIG, associated benchmark and STIG Viewer to assess the controls documented within the system security authorization package.
Industry is not required to STIG their systems. However, they must identify their baseline standards within their system security authorization package (e.g. NIST, NSA, STIG). DCSA as the Security Control Assessor (SCA) and NISP authorization authority will leverage the DISA STIGs for assessment of the implementation of RMF technical security controls.
If the system cannot be assessed using the specified scanning tools, Industry must document the justification and process for assessing the system in the system security authorization package. The assessment will then be conducted in accordance with the system security authorization package.
The ISSP (SCA) and Authorizing Official with oversight of the system can utilize any STIG deemed applicable in their official assessment of the NISP system, however the compliance or non-compliance of each individual control must be validated against any STIG findings.
There is no "requirement" for a specific set of STIGs to be implemented. Prepared by NISP Authorization Office (NAO) 7/22/2019 v1.0 they serve as a benchmark from which the SCA's assessment of security controls can begin. All applicable security controls (according to the security categorization and risk assessment) must be addressed, and residual risk from vulnerabilities mitigated to the satisfaction of the Authorizing Official.
- The DISA “STIG Master List” provides a repository of all current STIG resources available.
- If STIGs are not developed for a particular system or application, organizations can substitute a Security Requirements Guide (SRG).
- There may be cases when a STIG is not available for a current hardware, firmware, operating system, or application.
