The Challenge
The Colonial Pipeline attack in May 2021 highlighted a critical issue: cybersecurity is no longer just an IT problem; it's a national security concern. This incident revealed that voluntary cybersecurity measures weren't enough to protect the 16 critical infrastructure sectors identified by CISA. The National Cybersecurity Strategy, released on March 2, 2023, recognized this and called for mandatory cybersecurity requirements across these sectors. The challenge now is finding a scalable model that can be applied across diverse sectors like aviation, water utilities, and the defense industrial base without each agency creating its own framework from scratch.
The Environment and Constraints
The scale of securing critical infrastructure is immense. The defense industrial base includes 100,000 firms, with compliance costs for CMMC 2.0 estimated at $10 billion annually. The aviation sector, guided by TSA as of March 7, 2023, involves around 19,700 organizations. The EPA's guidance for water utilities on March 3, 2023, impacts 153,000 public drinking water systems and over 16,000 treatment facilities. Each sector has unique challenges, but all require robust cybersecurity defenses. Building separate frameworks for each would be inefficient and time-consuming.
The most pressing constraint is time. Critical infrastructure can't afford to wait for new frameworks to develop.
The Approach in Practice
FedRAMP provides a proven model. Since 2011, it has accredited nearly 300 commercial cloud services, with 4,600 instances of agency reuse. This demonstrates its value: one rigorous authorization can replace numerous assessments.
FedRAMP's success is based on two key pillars. First, it establishes a consistent security baseline through formal authorization requirements. Cloud service providers must implement NIST SP 800-53 controls, undergo third-party assessments, and receive an Authority to Operate. Second, continuous monitoring ensures that security isn't a one-time check. Providers must submit monthly reports and maintain their security posture under ongoing scrutiny.
This model can be adapted for critical infrastructure. Each Sector Risk Management Agency (SRMA) could set baseline requirements, accredit solutions, and maintain a marketplace of pre-authorized services. For example, a water utility could choose from pre-vetted SCADA monitoring tools, avoiding lengthy assessments with limited cybersecurity expertise.
The strategy recommends mandating FedRAMP or StateRAMP accredited solutions where applicable, especially for entities receiving federal cybersecurity grants. This isn't about forcing operators onto government platforms but ensuring that vetted commercial solutions are the default choice.
Results and Demonstrated Value
FedRAMP has saved millions in compliance costs, though a comprehensive cost-avoidance study hasn't been published. Its marketplace serves as a benchmark beyond federal use, with state agencies and international organizations recognizing FedRAMP authorization as a cybersecurity standard.
StateRAMP and TX-RAMP are adaptations of the FedRAMP model for state-level procurement, proving its portability. A McKinsey survey found that regulated sectors adopt cloud solutions faster, suggesting clear authorization pathways facilitate adoption.
The reuse metric is a clear success indicator. When 4,600 agency instances rely on 300 authorizations, it shows the network effects of shared security validation.
What Could Work Better
A significant bottleneck is the FedRAMP authorization queue. Small businesses and startups struggle to get initial sponsorship for Authority to Operate, limiting their market entry. Offering SBIR grants for FedRAMP costs and SRMA sponsorship for innovative solutions could address this gap. Critical infrastructure sectors need solutions tailored for smaller budgets, often provided by startups.
Another issue is the lack of standardization across frameworks. While NIST SP 800-53 underpins FedRAMP, CMMC builds on NIST SP 800-171, and other frameworks reference the NIST Cybersecurity Framework. Expanding the use of Open Security Controls Assessment Language (OSCAL) for consistent control documentation and monitoring could streamline compliance across frameworks.
What Your Team Should Do
If you're a compliance officer in a critical infrastructure sector, focus on these actions:
Inventory your current solutions against FedRAMP and StateRAMP marketplaces. When procuring cloud services or security tools, check for FedRAMP-authorized options. If they exist, justify any non-authorized choices by explaining why they don't meet your needs.
Map your sector's requirements to NIST SP 800-53 controls. Whether your SRMA adopts a FedRAMP-style model or a sector-specific one, the control baseline will likely reference 800-53. Understanding how your security posture aligns with these controls positions you ahead of mandate deadlines.
Watch for SRMA guidance on authorized solution marketplaces. TSA issued aviation guidance on March 7, 2023, and EPA issued water sector guidance on March 3, 2023. Your sector's guidance is forthcoming. Align procurement cycles to take advantage of authorized options rather than committing to long-term contracts that won't meet new mandates.
The shift from voluntary to mandatory requirements is underway. FedRAMP has proven the authorization model works at scale. Your sector is next.
