CYBERSECURITY FIRST


to create a ZT readiness profile and was successful in enhancing system security without duplicating efforts.


Te focused approach of optimizing current configurations for ZT alignment allowed the team to make systems more resilient. Building upon the RMF ensured a smoother transition to ZT with minimized disruptions.


Te transformative effort involves aligning current cybersecurity guidelines with more efficient, beefed-up ZT security measures. Te SEC is referencing the Department of Defense (DOD) Zero Trust Overlay, a document published in June 2024, to meticu- lously map the Control Correlation Identifiers (CCIs). Mapping the CCIs makes the policy implementable and measurable.


“Te Zero Trust framework is not a new piece of technology per se, nor a service that one can acquire and implement. In essence, it’s a concept that, in simpler terms, is ‘never trust, always verify,’ ” said Shah. “To holistically achieve Zero Trust, we’re not coming up with anything new that the Army hasn’t seen—we’re


building upon our current capabilities, and we are building Zero Trust in,” she added.


Te overarching aim of developing a ZT implementation policy baseline was to further bolster the Army’s efforts in protecting critical data from the preying advances of nation-state and non- nation-state attackers and rogue hackers who intend to harm and disrupt U.S. interests across its cyber infrastructure and beyond. Te new policy stands as another case of the Army’s require- ment to employ enhanced, sturdier countermeasures in the face of emerging, ever-changing cybersecurity threats. Te first-of- its-kind effort seeks to aid the Army in maintaining constant vigilance of critical network resources while rigorously adapting its cyber posture to stay ahead of the game.


BUILD ON THE FOUNDATION Te SEC is using the DOD Zero Trust Security Control Overlay to map and implement changes to the current RMF. Mapping the new policy to the existing RMF is critical to upgrading the cyber posture.
