The general problem of this quantitative survey research was DoD did not execute an RMP governance approach as informed by NIST SP 800-39, Managing Information Security Risk, thereby jeopardizing national security interests. (Bayer et al., 2019; DoDIG, 2018, 2019; GAO, 2018b; Maclean, 2017; NIST, 2011b, 2018b; OMB, 2018; Schall, 2018). The specific problem was DoD did not implement organization-wide cybersecurity risk management policy, resulting in exploitable at-risk DoD information and ISs (Bayer et al., 2019; DoDIG, 2018, 2019; GAO, 2018a, 2018b; NIST, 2011b, 2018b; Schall, 2018). The purpose of this research was to evaluate to what extent RMF practitioners who earned DoD 8570.01M IAM Level III certifications were a predictor of Tier 1/organizational level RMF policy implementation ability as informed by NIST SP 800-39 and NIST SP 800-37r2. Each of the four research questions asked if there was a relationship between DoD 8570.01M IAM Level III certification and a perceived ability to implement one of four RMF Prepare step organizational level tasks. The research used a correlational design to evaluate the relationship between four RMF Prepare step organizational level task outcome variables and a single predictor variable, the number of DoD 8570.01M IAM Level III certifications earned. Based on this research, there is no correlation between a perceived ability to implement RMF Prepare step organizational level tasks referencing the NIST SP 800-39 and any number of earned or unearned DoD 8570.01M IAM Level III certifications. However, this study did find two statistically significant outcome variable differences among RMF practitioners who earned three DoD 8570.01M IAM Level III certifications suggesting targeted certification relevance.
