      Documentation Requirements

      Introduction

      The Federal Risk and Authorization Management Program (FedRAMP) ensures that cloud services used by federal agencies meet stringent security standards. The Assessment Phase is crucial for evaluating the security posture of Cloud Service Providers (CSPs) and involves extensive documentation. This article focuses on the detailed requirements for the System Security Plan (SSP) and the preparation of the Security Assessment Plan (SAP) and Security Assessment Report (SAR).

      Detailed Requirements for the System Security Plan (SSP)

      Overview of the SSP

      The System Security Plan (SSP) is a comprehensive document that describes how a CSP's information system meets the security requirements outlined by FedRAMP. It serves as a blueprint for the implementation, assessment, and management of the security controls.

      Key Components of the SSP

      • System Identification:
        • System Name and Identifier: Unique identification for the system.
        • System Owner and Point of Contact: Details of the individuals responsible for the system.
      • System Description:
        • System Purpose: An overview of the system's function and its criticality.
        • System Architecture: Detailed diagrams and descriptions of the system's architecture, including network components and data flow.
      • Security Categorization:
        • Based on the FIPS 199 standards, the security categorization defines the system's impact level (Low, Moderate, or High) on confidentiality, integrity, and availability.
      • Security Control Implementation:
        • NIST SP 800-53 Controls: Detailed descriptions of how each security control from NIST SP 800-53 is implemented within the system.
        • Control Allocation: Identifying who is responsible for each control, whether it is the CSP, the customer, or jointly managed.
      • Risk Assessment:
        • Risk Management Strategy: A comprehensive strategy for identifying, assessing, and mitigating risks.
        • Risk Assessment Results: Documented results of the risk assessment, including identified risks and their mitigation strategies.
      • Contingency Planning:
        • Contingency Plan: Procedures for responding to emergencies and restoring normal operations.
        • Disaster Recovery: Strategies and plans for recovering from catastrophic events.
      • Continuous Monitoring:
        • Monitoring Strategy: Ongoing monitoring of security controls to ensure their effectiveness.
        • Incident Response: Procedures for detecting, responding to, and recovering from security incidents.

      Preparing the Security Assessment Plan (SAP) and Security Assessment Report (SAR)

      Security Assessment Plan (SAP)

      The SAP outlines the scope, methodology, and schedule for the security assessment. It is essential for ensuring that the assessment is thorough and systematic.

      Key Components of the SAP

      • Assessment Scope:
        • System Boundaries: Define the boundaries of the system to be assessed, including interconnected systems.
        • Assessment Objectives: Clearly state the objectives of the assessment, such as verifying compliance with security controls.
      • Assessment Methodology:
        • Assessment Techniques: Describe the techniques to be used, including interviews, document reviews, and technical testing (e.g., vulnerability scanning, penetration testing).
        • Sampling Methods: Define the sampling methods to be used for testing security controls.
      • Assessment Schedule:
        • Timeline: Provide a detailed timeline for the assessment activities, including milestones and deadlines.
        • Resources: List the resources required for the assessment, such as personnel and tools.
      • Assessment Team:
        • Roles and Responsibilities: Define the roles and responsibilities of the assessment team members.

      Security Assessment Report (SAR)

      The SAR documents the results of the security assessment, including the effectiveness of the security controls and any identified vulnerabilities. It is a critical document for obtaining FedRAMP authorization.

      Key Components of the SAR

      • Assessment Results:
        • Control Effectiveness: Detailed findings on the effectiveness of each security control.
        • Vulnerability Findings: List of identified vulnerabilities, their severity, and potential impact.
      • Risk Analysis:
        • Risk Level: Assess the risk level of identified vulnerabilities based on their likelihood and impact.
        • Mitigation Strategies: Provide recommendations for mitigating identified risks.
      • Conclusion and Recommendations:
        • Overall Security Posture: Summarize the overall security posture of the system based on the assessment results.
        • Remediation Actions: Outline recommended remediation actions and timelines for addressing identified vulnerabilities.

      For a comprehensive guide on preparing the SAR, refer to the FedRAMP SAR Template.

      Conclusion

      The documentation requirements for the FedRAMP Assessment Phase are critical for ensuring that cloud services meet federal security standards. By meticulously preparing the SSP, SAP, and SAR, CSPs can demonstrate their commitment to security and enhance their chances of achieving FedRAMP authorization.
