Diving Deeper into Ongoing ConMon Requirements

Monthly requirements form the foundation of your ConMon process. Each month, you must conduct vulnerability scans of your systems and networks, analyze the results and update your Plan of Action and Milestones (POA&M) accordingly. The POA&M itself needs to be reviewed and updated, tracking progress on addressing identified vulnerabilities and security weaknesses. It's also essential to report any significant changes to your system, including new features, major updates, or changes in system architecture. Lastly, you must submit reports for any security incidents that occurred during the month, even if there were none.

Quarterly requirements build upon your monthly activities, providing a more comprehensive view of your security posture. Every three months, you need to provide an update on the status of your security controls, highlighting any changes or improvements. You should also report any modifications to your cloud service offering that might impact your security posture. Additionally, it's necessary to submit an updated inventory of your system components, including hardware, software, and interfaces.

Annual requirements involve more in-depth assessments and testing. Once a year, you must conduct a comprehensive security assessment of your system, typically performed by a Third Party Assessment Organization (3PAO). This is accompanied by penetration testing to identify potential vulnerabilities that may not be detected through regular scanning. You're also required to test your contingency plans to ensure they remain effective and up-to-date. Lastly, you need to review and update your System Security Plan (SSP) to reflect any changes in your system or security controls over the past year.

In addition to these timeline-based requirements, there are ongoing activities that you must maintain continuously. These include maintaining ongoing monitoring of your system's security status, with real-time alerting for potential security events. It's crucial to keep your agency customers informed about your system's security status, including any significant changes or identified risks. Additionally, you need to continuously monitor and manage your system's configuration to maintain a secure state.

ConMon is a high communication routine with CSPs who must actively engage with their federal clients. This includes providing regular reports, participating in security reviews, and addressing any concerns or findings raised by the agencies. 

Selecting the Right FedRAMP GRC Solution

As a CSP, Governance, Risk, and Compliance (GRC) software plays a crucial role in managing your FedRAMP Continuous Monitoring (ConMon) process. Here are the key roles of GRC software in FedRAMP ConMon and their limitations:

Key Roles of GRC Software for ConMon:

GRC software centralizes your security control management, allowing you to track the implementation and status of all required FedRAMP controls in one place. It provides a comprehensive view of your compliance posture, making it easier to identify gaps and prioritize remediation efforts.

These tools often include automated data collection features, which can significantly streamline your ConMon reporting process. They can automatically gather data from various security tools, reducing manual effort and the risk of human error in compiling monthly and quarterly reports.

GRC platforms typically offer robust POA&M management capabilities. They help you track identified vulnerabilities, remediation plans, and progress over time. This is crucial for maintaining an up-to-date POA&M, which is a key requirement of FedRAMP ConMon.

Quality GRC tools provide dashboard and reporting features that can generate FedRAMP-specific reports. This can save time and ensure consistency in your reporting to the FedRAMP PMO and your agency customers.

ConMon Limitations with Software:

While GRC software offers many benefits, it's important to understand its limitations:

GRC tools can only be as effective as the data they receive. If your security tools or manual processes aren't capturing all the necessary information, your GRC platform won't provide a complete picture of your security posture.

These platforms often require significant initial setup and ongoing maintenance to align with FedRAMP's specific requirements. This can be time-consuming and may require specialized expertise.

Even with promised AI features, GRC software won't customize or implement the controls that you need, nor will it update them as your ConMon deals with new challenges. This role requires the involvement of FedRAMP experienced implementers and IT security experts.

While GRC software can help manage compliance, it doesn't automatically ensure compliance. You still need knowledgeable staff to interpret results, make decisions, and take appropriate actions.

Some GRC tools may not fully align with all FedRAMP requirements out of the box. You might need to customize the tool or supplement it with additional processes to meet all FedRAMP ConMon requirements.

GRC software can be expensive, both in terms of initial implementation and ongoing licensing costs. This can be a significant consideration, especially for smaller CSPs.

While these tools can automate many aspects of ConMon, they can't replace the need for human judgment in risk assessment and decision-making. Critical thinking and expert analysis remain essential in maintaining FedRAMP compliance.

By understanding both the capabilities and limitations of GRC software, you can make informed decisions about how to best leverage these tools in your FedRAMP ConMon process. Remember, GRC software should be viewed as a valuable tool to support your compliance efforts, not as a complete solution on its own.

One good example of a GRC software that aligns with FedRAMP requirements and includes implementation and expert configuration is Federal ZenGRC which specifically addresses both the compliance and implementation challenges of FedRAMP ConMon.
