Navigating FedRAMP Rev. 5 Baselines: Everything You Need to Know

The Federal Risk and Authorization Management Program (FedRAMP) program is vital for securing and ensuring compliance of Cloud Service Providers (CSPs) and Third-Party Assessment Organizations (3PAOs) serving federal departments, agencies, and commercial organizations.


The recent approval of the FedRAMP Rev. 5 baselines by the Joint Authorization Board (JAB) is a significant step forward in the cloud security and compliance domain. This update aligns the new and upgraded baselines closely with the NIST SP 800-53 Rev. 5 security controls, enhancing CSPs’ and 3PAOs’ security posture and promoting consistency in federal security practices. It safeguards sensitive information and streamlines the authorization process.

FedRAMP Rev 5: What’s New!

FedRAMP Rev. 5 introduces significant cybersecurity enhancements, including 66 new controls, 1 new control family, Supply Chain Risk Management, and an enhanced Privacy control family for Personally Identifiable Information Processing and Transparency. There are 135 control changes, 134 parameter, guidance, or requirement changes, 90 controls moved requirements, and 9 withdrawn controls. These changes prioritize cybersecurity practices rather than just increasing the number of controls. The new FedRAMP Rev 5 Baselines include:
  • Significant guidance for security controls implementation
CSPs, 3PAOs, and Federal departments and agencies receive detailed instructions and recommendations for transitioning to NIST SP 800-53 Rev. 5 and meeting new FedRAMP requirements. The FedRamp Program Management Office (PMO) has equipped stakeholders with a set of critical documents essential for a smooth transition. These valuable resources encompass the Rev. 5 Baselines, CSP transition plans, and a succinct yet comprehensive comparison summary outlining the key distinctions between Rev. 4 to Rev. 5 Baselines.
FedRAMP Rev. 5 categorizes CSPs based on their authorization stage and establishes specific transition periods. The plan assists CSPs to identify which Rev. 5 controls require assessment testing, providing clear guidance on scope and requirements. It minimizes uncertainties and facilitates a smooth transition to Rev. 5. It includes:
  • Transition timelines and requirements based on the CSP’s authorization phase (Planning, Initiation,  or Continuous Monitoring).
  • Clear tasks: developing a schedule, updating documentation, determining assessment scope, conducting security assessment, and managing risks for inherited controls.
  • Guidance on addressing risks with continued use of CSPs (e.g., IaaS and PaaS) undergoing  transition.
  • Guidelines to align with NIST SP 800-53 Rev 5 and SP 800-53B
Rev 5 baselines closely align with NIST SP 800-53 Rev. 5 and SP 800-53B (Security Control Baselines). NIST introduced NIST SP 800-53B to enhance the application of Rev. 5 guidelines in diverse organizations and environments. This publication provides guidance and assumptions for tailoring security controls to protect critical operations, assets, and individual privacy. It also offers insights on creating overlays to customize control baselines for specific communities, technologies, and environments. Stakeholders can voluntarily share security control overlays through NIST’s Security Control Overlay Repository (SCOR). This alignment promotes the use of the NIST Open Security Controls Assessment Language (OSCAL) format for package submission, expediting review, and approval processes.
  • Enhanced Focus on Privacy and Supply Chain Security: Rev. 5 places a strong emphasis on privacy and supply chain security with one new control family and another enhanced version of the privacy control family. The Privacy Baseline and Personally Identifiable Information Processing and Transparency controls are now integrated into the main catalog (from being in Appendix J in Rev 4), enhancing cybersecurity measures for healthcare applications and beyond. The addition of the new Supply Chain Risk Management controls addresses the rising concerns over critical infrastructure and government supply chain risks, bolstering cybersecurity practices in the federal ecosystem. Furthermore, Privacy controls and controls not covered by FedRAMP baselines are left to the agency’s discretion, allowing for tailored solutions while maintaining a robust cloud security framework.
  • Program Management (PM) Controls Not Included in Baselines

The agency retains responsibility for Program Management (PM) controls, which are not included in the FedRAMP baselines. This means that agencies are responsible for managing program-level controls, such as risk management, governance, and oversight, tailored to their specific organizational requirements. By excluding PM controls from the baselines, FedRAMP recognizes the agency’s accountability in ensuring effective program management practices while focusing on the security controls applicable to the cloud services provided by CSPs.

  • Flexibility in Control Implementation: Rev. 5 eliminates the prioritization guidance for controls within a baseline, providing organizations with greater flexibility. Unlike Rev. 4, Rev. 5 allows each organization to implement and manage baseline controls based on their specific needs and threat landscape, enabling a more customized approach to cloud security.
  • Unified Documentation Structure: Three System Security Plans (SSPs) were consolidated into a single SSP, reducing redundancy, and improving efficiency. Similarly, to enhance simplicity and coherence, two Security Assessment Report (SAR) templates were merged into one, as well as two Security Assessment Plan (SAP) templates, which were also combined into a single template. This consolidation aims to create a more unified and straightforward documentation structure, making it easier for stakeholders to manage and navigate the security processes.
  • Simplified Controls Implementation: Rev 5 has merged the two separate CIS (Control Implementation Summary) workbook templates from Rev 4 into a single, streamlined CIS workbook template. Furthermore, a new workbook called CRM (Control Rationalization Matrix) has been introduced to complement the CIS workbook. This consolidation simplifies documentation, providing a more efficient way to manage control implementation and rationalization. The CIS and CRM workbook template offers a comprehensive view of the control landscape.
Both NIST and FedRAMP offer low, moderate, and high baselines for system categorization, based on Federal Information Processing Standards (FIPS) 199 criteria related to confidentiality, integrity, and availability of data. Notably, each baseline has been updated to include a new set of controls:

Implications for CSPs and Third-Party Assessment Organizations (3PAOs)

  • Continuous Monitoring: FedRAMP Rev 5 places increased emphasis on automation and continuous monitoring of CSPs. It requires regular assessments to evaluate the effectiveness of security controls and risk management practices. This shift encourages a proactive approach, allowing agencies to identify and mitigate security risks in real-time.
  • Authorization Boundary: There is continued focus on authorization boundary to ensure that the cloud system’s internal components and connections to external services and systems processing federal data or metadata should be included within the authorization boundary or reside in a FedRAMP authorized system at the same FIPS-199 impact level.
  • Integrated Inventory: It introduces an integrated inventory approach to ensure comprehensive visibility into all authorized cloud services. It requires CSPs to maintain an inventory of all systems and components to facilitate effective security management and enable accurate risk assessments. This enables CSPs and 3PAOs to make informed decisions regarding risk management, ensuring that security controls align with their specific requirements.
  • Enhanced Threat-Based Approach: It integrates MITRE ATT&CK Framework, prioritizing threat-based intelligence. Controls are optimized to mitigate specific risks while minimizing additional requirements beyond NIST Rev. 5. This flexibility enables organizations to align security measures with their unique threat landscape effectively.

The inclusion of NIST-aligned security controls, the provision of significant guidance for controls, and the recognition of agency discretion for privacy and other controls in FedRAMP Rev 5 baselines signify an evolution toward a more comprehensive and flexible framework. This evolution enables CSPs and 3PAOs to adhere to industry best practices and empowers agencies to tailor their security approaches while maintaining a high level of security and compliance in the federal cloud environment.
