Ensuring Continuous Compliance: Key Requirements for FedRAMP's OA&A Phase
The Federal Risk and Authorization Management Program (FedRAMP) ensures that cloud services used by federal agencies meet stringent security standards. An essential component of maintaining FedRAMP compliance is the Continuous Monitoring Phase, specifically the Ongoing Assessment and Authorization (OA&A). This phase involves continuous monitoring requirements and best practices, including the mandatory 90 days of Continuous Monitoring (CM) before a Third-Party Assessment Organization (3PAO) assessment.
Continuous Monitoring Requirements
Overview
Continuous monitoring involves the ongoing assessment of a Cloud Service Provider’s (CSP) security controls to ensure they remain effective over time. This process is critical for identifying and mitigating new vulnerabilities and threats as they emerge.
Key Requirements
-
Automated Monitoring Tools:
Utilize automated tools to continuously monitor the security controls and system activities. These tools help detect anomalies, unauthorized access attempts, and other security incidents in real-time.
-
Regular Vulnerability Scans:
Conduct regular vulnerability scans to identify and address security weaknesses. This includes both internal and external scans to ensure comprehensive coverage.
-
Patch Management:
Implement a robust patch management process to ensure that all software and hardware components are up to date with the latest security patches and updates.
-
Configuration Management:
Continuously monitor and manage system configurations to prevent unauthorized changes and ensure compliance with security policies.
-
Incident Response:
Maintain an effective incident response plan to quickly address and remediate security incidents. This includes regular testing and updating of the incident response plan.
90 Days Continuous Monitoring Requirement
Before undergoing a 3PAO assessment, CSPs must demonstrate at least 90 days of continuous monitoring. This period allows CSPs to implement and document their continuous monitoring processes effectively. The 90 days of continuous monitoring involves:
-
Implementing Monitoring Tools:
Deploy and configure automated monitoring tools to capture system activities and security events continuously.
-
Conducting Regular Assessments:
Perform regular security assessments and vulnerability scans during the 90-day period to ensure all security controls are functioning as intended.
-
Documenting Findings:
Document all findings, incidents, and remediation actions taken during the 90 days. This documentation is crucial for the subsequent 3PAO assessment.

Reporting and Documentation for Ongoing Assessment
Importance of Reporting
Accurate and timely reporting is essential for maintaining FedRAMP compliance. It ensures that federal agencies and the FedRAMP Program Management Office (PMO) are aware of the CSP's security posture and any potential risks.
Key Reporting Elements
-
Security Status Reports:
Submit regular security status reports to the FedRAMP PMO. These reports should detail the results of continuous monitoring activities, including vulnerability scans, incident responses, and system changes.
-
Plan of Action and Milestones (POA&M):
Maintain and update the POA&M document, which outlines identified vulnerabilities, planned remediation actions, and timelines for addressing these issues.
-
Incident Reports:
Report any security incidents promptly, detailing the nature of the incident, its impact, and the steps taken to remediate it. Regular updates on incident resolution progress should also be provided.
-
Annual Security Assessments:
Conduct annual security assessments to verify the continued effectiveness of security controls. These assessments should be documented and submitted as part of the ongoing compliance process.
-
Audit Logs:
Maintain detailed audit logs of all system activities and security events. These logs should be regularly reviewed and analyzed to detect and respond to potential security threats.
For comprehensive guidelines on reporting and documentation requirements, refer to the FedRAMP Continuous Monitoring Performance Management Guide.
Conclusion
The Continuous Monitoring Phase, particularly the Ongoing Assessment and Authorization (OA&A), is a crucial aspect of the FedRAMP authorization process. By adhering to continuous monitoring requirements and best practices, and ensuring accurate and timely reporting, CSPs can maintain their FedRAMP compliance and ensure the security and integrity of their cloud services.
