Analysis Summary
# Regulation/Compliance: CISA Cybersecurity Performance Goals (CPGs) Adoption Summary
## Overview
This summary covers the guidance provided by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) regarding the voluntary adoption of Cybersecurity Performance Goals (CPGs) by organizations operating within the nation's critical infrastructure sectors to enhance cyber resilience. The CPGs are designed to help organizations prioritize cybersecurity investments and actions proactively.
## Key Details
- Issuing Authority: Cybersecurity and Infrastructure Security Agency (CISA)
- Effective Date: Initially introduced in October 2022; guidance reorganized in March 2023.
- Jurisdiction: United States, focusing on the 16 critical infrastructure sectors.
- Status: Voluntary Guidelines/Recommendations.
## Requirements
### Mandatory Requirements
*As the CPGs are presented as voluntary measures by CISA, there are currently no explicit federal *mandatory* requirements detailed in this context. Compliance is driven by the organization's risk management strategy and potential future rulemaking.*
1. **Adoption Intent:** Critical infrastructure owners are encouraged to adopt the CPGs to safeguard against cyber threats.
2. **Alignment for Investment Prioritization:** Organizations should use the CPGs to prioritize cybersecurity investments as part of a broader program built around the NIST Cybersecurity Framework (CSF) functions.
### Recommended Practices
1. **Risk Reduction:** Implement the suggested cybersecurity practices to achieve measurable reductions in cyber risks.
2. **Vulnerability Management:** Actively work to reduce the number of exploitable services monitored by CISA Vulnerability Scanning (data shows positive trends among adopters).
3. **Remediation Speed:** Focus on decreasing remediation times, especially for Critical and High-severity Known Exploited Vulnerabilities (KEVs) and SSL vulnerabilities.
4. **OT/ICS Exposure Mitigation:** Review and mitigate the exposure of Operational Technology (OT) and Industrial Control Systems (ICS) protocols to the public internet, especially in sectors like Government Services.
## Affected Organizations
- Industries: All 16 U.S. critical infrastructure sectors, with notable analysis focus on:
- Healthcare and Public Health
- Water and Wastewater Systems
- Communications
- Government Services and Facilities
- Organization Size: Not explicitly size-dependent; applies based on sector designation.
- Geographic Scope: United States Critical Infrastructure.
## Compliance Timeline
- October 2022: CISA CPGs initially introduced.
- March 2023: CPGs reorganized, reordered, and renumbered to align with NIST CSF functions.
- Aug 1, 2022 – Aug 31, 2024: Period analyzed for CPG adoption trends.
- **Final deadline:** Not applicable, as adoption is voluntary guidance, though proactive adoption is strongly encouraged in light of continuous threat actors.
## Implementation Guidance
### Assessment Phase
- **Enrollment in CISA Services:** Organizations are encouraged to enroll in services like CISA Vulnerability Scanning and Cyber Hygiene (CyHy) to gain insight into current exposure metrics.
- **Protocol Identification:** Identify and inventory all publicly exposed OT/ICS protocols, particularly focusing on high-risk protocols like OPC Unified Architecture (OPC UA) if operating in sensitive sectors.
### Implementation Phase
- **NIST CSF Structuring:** Integrate CPGs directly into existing cybersecurity programs structured around the NIST CSF architecture.
- **Prioritization:** Use CPG adoption data to focus spending and effort on the highest-priority items showing the greatest return on risk reduction for the organization.
### Validation Phase
- **Metric Monitoring:** Monitor remediation metrics, such as the reduction in exploitable service counts and faster resolution of KEV tickets (aiming for significant decrease, e.g., reduction of SSL resolution time from ~200 days toward under 50 days).
- **CISA Feedback:** Observe adoption analytics provided by CISA as guidance evolves to infer better adoption practices.
## Technical Requirements
*The CPGs map directly to technical controls, though this summary focuses on the *outcomes* observed through CISA scanning:*
1. **Vulnerability Reduction:** Systematically reduce the number of exploitable services exposed.
2. **Secure Configurations:** Implement controls to reduce public exposure of core OT/ICS protocols (e.g., segmentation, hardened firewalls, secure remote access).
3. **Patching and Remediation:** Rapidly remediate critical vulnerabilities, particularly those listed in CISA’s KEV Catalog.
## Penalties & Enforcement
- **Fines:** Not specified in the context, as CPGs are voluntary guidelines, not mandatory regulations triggering statutory fines.
- **Other Consequences:** The primary impact of non-adoption is increased risk exposure to nation-state adversaries and cybercriminal organizations, leading to potential operational disruption or data loss in the event of a successful cyber attack.
- **Enforcement:** CISA enforces goals through collaboration, transparency (via adoption reports), and encouragement rather than punitive legal action for non-adopters.
## Related Standards
- **NIST Cybersecurity Framework (CSF):** CPG structure and guidance are directly reorganized and renumbered to align with the five functions of the NIST CSF.
- **CISA KEV Catalog:** The CPGs work in tandem with the KEV Catalog, emphasizing the proactive remediation of known exploited vulnerabilities.
- **CISA PRNI:** The Pre-Ransomware Notification Initiative is another complementary CISA effort focused on enhancing collective resilience.

- Guidance Documents: CISA KEV Catalog, CISA PRNI guidance.
- Tools: CISA Vulnerability Scanning Service, CISA Cyber Hygiene (CyHy) Service.
## Practical Recommendations
1. **Engage Proactively:** Critical infrastructure entities should proactively engage with CISA programs (Vulnerability Scanning, CyHy) to establish a baseline against which CPG implementation can be measured.
2. **Map to CSF:** Ensure all adopted CPG controls are mapped explicitly to the existing NIST CSF structure to facilitate resource planning.
3. **Prioritize OT Risk:** Sectors must specifically audit and restrict public-facing exposure of OT/ICS protocols, given the high rates observed in sectors like Government Facilities.
4. **Measure Reduction:** Track remediation timelines and the reduction in exploitable services as tangible evidence of successful CPG implementation and risk reduction efforts.
