By maintaining thoroughness in control implementation, organizations can not only fulfill FedRAMP requirements but also create a more secure environment for sensitive information.

Methodical Approach to Control Inheritance

What is Control Inheritance?

Control inheritance refers to the practice of relying on security controls implemented by another organization or system, rather than duplicating those controls within one's own system security plan (SSP). This approach is often used when a cloud service provider (CSP) utilizes external services or third-party solutions that already have established security measures in place. Understanding control inheritance is crucial for creating a comprehensive and efficient system security plan.

How to Document Inherited Controls

Documenting inherited controls should be a systematic process to ensure clarity and compliance. Key steps include:

1. Identify Inherited Controls: Determine which controls will be inherited and from which sources they originate.
2. Reference Documentation: Link back to the original sources that define and describe these inherited controls. This can involve citing existing compliance documents, such as FedRAMP authorization reports.
3. Assessment of Control Effectiveness: Evaluate the effectiveness of the inherited controls, noting any areas that are not sufficiently addressed within the source documentation.
4. Integrate into SSP: Incorporate these evaluations and references into the SSP, clearly indicating which controls are inherited.

A structured table can help summarize the inherited controls and their sources.

Key Considerations for Inherited Controls

When dealing with inherited controls, several critical factors should be taken into account:

• Responsibility: While controls may be inherited, the organization remains responsible for ensuring their effectiveness. It's important to maintain oversight and ensure adequate documentation, including any necessary updates.
• Cross-Reference Existing Documents: Ensure that all inherited controls are aligned with existing compliance documents, such as those related to POA&M management.
• Collaboration with Third-Party Organizations: Engage with the controlling organizations to verify their operational status, making sure controls are currently effective and compliant with standards.
• Adaptation to Changes: Be prepared to reassess inherited controls regularly, especially in a rapidly evolving cybersecurity landscape. Changes in the cloud environment or third-party operations may necessitate adjustments to the inherited controls.

By applying a methodical approach to control inheritance, organizations can strengthen their SSP while maintaining compliance with FedRAMP requirements. For more information on the broader FedRAMP authorization process, consider reviewing related guidelines.

Accurate Boundary Descriptions

What is a Boundary Description?

A boundary description outlines the limits of the system and the environment in which it operates. It defines what components and services fall within the scope of the system security plan (SSP). Boundary descriptions are critical for ensuring that compliance measures are applied effectively. They help identify the system's assets, including databases, applications, services, and network components, thus providing clarity on what is being protected under FedRAMP policies.
