FedRAMP Program
FedRAMP is a U.S. government program that standardizes the security assessment, authorization, and continuous monitoring of cloud products and services. Its primary goal is to speed up the adoption of secure cloud solutions across the federal government.
This government program uses NIST 800-53 Rev. 5 controls as the baseline for its security requirements.
In short, this means that cloud service providers seeking FedRAMP authorization must demonstrate compliance with the security controls outlined.
FedRAMP categorizes cloud services into three impact levels: Low, Moderate, and High.
Each level corresponds to the sensitivity of the data handled and has its own set of security controls derived from NIST SP 800-53.
This categorization ensures that security measures are tailored to the specific risk profiles of different systems, enabling a more targeted and effective approach to cybersecurity.
Now, let’s talk about the controls and their relationship with FedRAMP.
NIST SP 800-53 Rev. 5 Controls and FedRAMP
As we mentioned NIST 800-53 Rev. 5 includes a set of security controls organized into families.
Here is a brief overview of the 20 control families:
1) Access Control (AC)
Restrict and manage access to information systems and data.
2) Awareness and Training (AT)
Promote security awareness and provide training programs to enhance the knowledge and capabilities of personnel, reducing security risks associated with human factors.
3) Audit and Accountability (AU)
Ensure accountability, detect incidents, and support investigations.
4) Assessment, Authorization, and Monitoring (CA)
Assess and authorize information systems for use and continuously monitor to ensure ongoing compliance and security.
5) Configuration Management (CM)
Establish and maintain a secure baseline configuration for information systems.
6) Contingency Planning (CP)
CP is designed to establish effective measures for preparing and responding to disruptions in information system operations.
The goal is to ensure the availability and integrity of critical systems and data during and after incidents.
7) Identification and Authentication (IA)
The Identification and Authentication control family aims to establish and enforce processes that uniquely identify and verify the identity of users, devices, and processes accessing information systems.
This is crucial for ensuring that only authorized entities gain access to system resources.
8) Incident Response (IR)
Prepare for, detect, respond to, and recover from security incidents.
9) Maintenance (MA)
System maintenance addresses the information security aspects of the system maintenance program and applies to all types of maintenance to system components conducted by cloud providers.
10) Media Protection (MP)
This control family focuses on safeguarding physical and digital media containing information. The objective is to prevent unauthorized access, disclosure, alteration, and destruction of sensitive information stored on various types of media.

11) Physical and Environmental Protection (PE)
This control family includes controls and guidelines to address the security of physical spaces, equipment, and environmental conditions.
Moreover, this encompasses measures to safeguard information systems against physical threats, environmental hazards, and unauthorized access.
12) Planning (PL)
Planning control family refers to a set of controls that focus on establishing and maintaining an organization-wide risk management framework and processes.
Furthermore, the objective of the Planning control family is to provide a structured approach to managing risk, ensuring that organizations can identify, assess, and mitigate potential risks to their information systems effectively.
13) Program Management (PM)
This control family defines a set of requirements that focus on establishing and maintaining an organization-wide information security program.
The objective is to ensure that an organization has a structured and comprehensive approach to managing information security, encompassing policies, procedures, and governance mechanisms.
14) Personnel Security (PS)
It focuses on establishing and maintaining processes to manage the security of individuals who have access to information systems and data.
At last, the objective of the Personnel Security control family is to ensure that individuals with access to sensitive information are trustworthy, reliable, and have the appropriate level of integrity to safeguard the organization’s assets.
15) PII Processing and Transparency (PT)
Personally identifiable information processing and transparency policies and procedures address the controls in the PT family that are implemented within systems and organizations.
The risk management strategy is an important factor in establishing such policies and procedures. Policies and procedures contribute to security and privacy assurance
16) Risk Assessment (RA)
Identify, assess, and manage risks to organizational operations and assets.
17) Systems and Service Acquisition (SA)
Its objectives are establishing security controls and measures during the acquisition, development, and implementation of information systems and services.
The goal is to ensure that security considerations are integrated throughout the entire life cycle of systems and services, from the initial planning and acquisition stages to deployment and ongoing operations.
18) System and Communications Protection (SC)
Protect the integrity, confidentiality, and availability of information during system and data communication processes.
19) System and information integrity (SI)
It focuses on protecting information systems and the integrity of the information processed, stored, and transmitted by those systems.
Moreover, the controls in this family aim to ensure that systems operate securely, detect and respond to unauthorized changes, and maintain the integrity of information throughout its lifecycle.
20) Supply Chain Risk Management (SR)
Manage and mitigate risks associated with the supply chain by addressing the need to manage and mitigate risks associated with the supply chain, which includes processes, people, technology, and other resources involved in the development, delivery, and maintenance of information systems.
Now, for FedRAMP compliance, controls and its associated enhancements are applicable based on the level of risk. Controls could be:
Applicable at All Levels:
- Some controls in NIST SP 800-53 Rev. 5 are relevant for all impact levels. For example, AC-14 (Permitted Actions without Identification or Authentication) might apply across all levels, but it’s essential to review the latest revision for any changes in control applicability or enhancements.
For Specific Impact Levels:
- Certain controls are designed only for Moderate and High-impact levels. For instance, AC-12 (Session Termination) may primarily apply to these levels, but verification with the latest Rev. 5 document is recommended to confirm its current categorization.
With Level-Specific Enhancements:
- Controls like AC-17 (Remote Access) often come with additional enhancements that vary depending on the impact level. In NIST SP 800-53 Rev. 5, there could be new enhancements or alterations in existing ones, tailoring the control more effectively to different security requirements.
Selecting Controls
The choice and execution of security and privacy controls must align with the goals of information security and privacy programs. These objectives and associated risks may operate independently or intersect depending on the context.
Federal information security programs aim to safeguard information and information systems. They ensure confidentiality, integrity, and availability by preventing unauthorized access, use, disclosure, disruption, modification, or destruction.
Additionally, they manage security risks and ensure compliance with relevant security requirements. Federal privacy programs focus on mitigating risks to individuals related to the processing of Personally Identifiable Information (PII). They ensure compliance with applicable privacy requirements.
When a system handles PII, both information security and privacy programs share the responsibility for addressing security risks associated with the PII. The controls chosen to manage these security risks are generally consistent, irrespective of their classification as security or privacy controls in control baselines or program/system plans.

Keep in mind:
There might be instances where the selection or implementation of a control impacts a program’s ability to meet its objectives and manage risks. The control discussion section may highlight specific security or privacy considerations. These considerations offer organizations insights to determine the most effective approach to implement the control.
However, these considerations are not exhaustive.
Enhancing Understanding and Implementation of Security Controls
In NIST SP 800-53 Rev. 5, each control offers a “Discussion” section. This section provides detailed information about specific security controls. This guidance helps organizations define, develop, and implement controls tailored to their unique operational contexts.
The “Discussion” section offers a detailed view of each control, explaining its purpose and application. This is useful when a control needs to be adapted to fit specific business requirements or address particular aspects of an organization’s risk assessment.
By reviewing these details, organizations can ensure that their implementation of controls is both effective and relevant to their specific security needs. This section clarifies the control’s function and offers insights into its broader implications within an organizational framework.
For controls with broader applications or those that need to be fine-tuned for specific scenarios, the supplemental guidance is helpful. It provides a comprehensive understanding of how a control operates, crucial for both implementing the control effectively and ensuring it aligns with the organization’s overall security posture.
Control Enhancements
The section on control enhancements describes security and privacy capabilities that enhance a foundational control. These enhancements are assigned sequential numbers within each control for easy identification when chosen to complement the base control.
Each enhancement has a brief subtitle indicating its intended function or capability. Control enhancements are used with their corresponding base controls. If a control enhancement is chosen, the associated base control must also be selected and implemented.
The references section provides applicable laws, policies, standards, guidelines, websites, and other valuable references pertinent to a specific control or its enhancement. This section includes hyperlinks to publications for additional information on control development, implementation, assessment, and monitoring.
Understanding FedRAMP: Streamlining Cloud Compliance for Federal Agencies
The Federal Risk and Authorization Management Program (FedRAMP) reshapes how federal agencies and Cloud Service Providers (CSPs) approach cloud computing services.
Essentially, it adapts the principles of the Federal Information Security Management Act (FISMA) for the cloud environment, standardizing security in this important area.
FedRAMP operates on a “do once, use many times” framework. This approach is designed to simplify and standardize the process of achieving FISMA compliance for Cloud Service Providers (CSPs).
Instead of multiple individual assessments, CSPs complete a single, comprehensive assessment applicable across various federal agencies.
This streamlines the process and reduces redundancy and costs.

Benefits and Goals
FedRAMP’s standardized approach to security and risk assessment for cloud technologies and federal agencies offers key advantages:
- Streamline Processes: Minimize inconsistencies and enhance cost-effectiveness by eliminating redundant efforts.
- Public-Private Partnership: Foster innovation and advance secure information technologies through collaboration.
- Rapid Adoption: Facilitate quick cloud computing adoption within the federal government with transparent standards.
- Secure Cloud Utilization: Expand the use of secure cloud technologies across government agencies.
- Improved Framework: Enhance the framework for securing and authorizing cloud technologies.
- Strong Partnerships: Cultivate and strengthen partnerships with FedRAMP stakeholders.
FedRAMP Authorization Process
You can achieve FedRAMP Authorization through two pathways: securing a provisional authorization via the Joint Authorization Board (JAB) or obtaining authorization through a specific agency.
Agency Authorization Route
In the Agency Authorization route, agencies can collaborate directly with a CSP for authorization. When a CSP engages with an agency to pursue an Authority to Operate (ATO), they navigate the FedRAMP Authorization process together.
The process is broken down into three phases:
1) Preparation
Readiness Assessment: CSPs can pursue the FedRAMP Ready designation, recommended for the Agency Authorization process. They work with an accredited Third Party Assessment Organization (3PAO) to conduct a Readiness Assessment. The resulting Readiness Assessment Report (RAR) outlines the CSP’s ability to meet federal security requirements.
Pre-Authorization: At this stage, the CSP should have a fully operational system and committed leadership aligned with the FedRAMP process. The CSP engages with FedRAMP by submitting a CSP Information Form and determining the data’s security categorization using the FedRAMP Federal Information Processing Standards (FIPS) 199 Categorization Template.
Pre-Authorization Steps:
- Ensure a fully built and functional system.
- Confirm leadership commitment for FedRAMP compliance.
- Engage with FedRAMP through the intake process.
- Determine data security categorization using relevant templates and guidelines.
2) Authorization
During the Full Security Assessment step, the 3PAO performs an independent audit of the system. Before this step, the CSP ensures that the System Security Plan (SSP) is complete and reviewed by the agency.
3) Continuous Monitoring
In this phase, the CSP must provide regular security reports (such as vulnerability scans, updated Plans of Action and Milestones, annual security assessments, incident reports, and significant change requests) to all agency customers.
More comprehensive information is available in the Continuous Monitoring Strategy Guide [PDF – 1.1MB].
Every agency using the service assesses the continuous monitoring reports monthly and annually. CSPs use the FedRAMP secure repository to publish monthly monitoring materials, ensuring convenient access and sharing with agency representatives.
