Implementing the technical security controls required to achieve and maintain an Authority to Operate (ATO) acts as a hidden tax on defense and commercial programs, consuming critical engineering hours and demanding scarce subject-matter expertise. Rather than building and sustaining these custom hardening capabilities from scratch, which typically takes months or years, programs are increasingly shifting toward prebuilt infrastructure.
Mercury Systems' RelianceOne for Linux provides a fixed-cost, pre-evaluated drop-in solution compatible with enterprise Linux distributions like RHEL. It accelerates the hardest parts of the Risk Management Framework (RMF) process by providing ready-made implementation narratives and threat models, allowing engineering teams to eliminate open-ended hourly development costs and secure a predictable path to authorization.
Read this white paper to learn about:
- How to address 94% of technical controls across 14 NIST SP 800-53 control families using a prebuilt solution.
- The financial and schedule advantages of a fixed-cost product over open-ended custom engineering services.
- Strategies to drop security protections into existing RHEL baselines without maintaining custom operating systems or kernel forks.
- Methods for utilizing pre-vetted threat models and test plans to speed up RMF documentation.
