NIST CSF Details
What It Is
NIST Cybersecurity Framework 2.0 (CSF 2.0) is a voluntary, risk-based guideline for managing cybersecurity risks. Developed by NIST, it provides a flexible structure for organizations of all sizes and sectors to assess, prioritize, and improve cybersecurity programs using a common language.
Key Components
- **Six Core FunctionsGovern (new), Identify, Protect, Detect, Respond, Recover.
- Organized into Categories (22 total) and Subcategories (112 outcomes).
- Implementation Tiers (Partial to Adaptive) for maturity evaluation.
- Profiles for aligning current and target states; no formal certification, self-attestation used.
Why Organizations Use It
- Enhances risk communication to executives and partners.
- Supports compliance demonstration and supply chain management.
- Drives prioritization, reduces threats cost-effectively.
- Builds stakeholder trust through strategic risk integration.
Implementation Overview
- Create Profiles for gap analysis and roadmaps.
- Map to existing standards; use Tiers for progression.
- Applicable globally, all industries; quick starts for SMEs, ongoing for enterprises. No audits required. (178 words)
CAA Details
What It Is
The Clean Air Act (CAA), codified at 42 U.S.C. §7401 et seq., is a U.S. federal statute establishing the national framework for air pollution control. Its primary purpose is protecting public health and welfare through ambient air quality standards and source emission limits. The cooperative federalism approach sets federal floors via EPA, with states implementing via enforceable plans.
Key Components
- NAAQS for six criteria pollutants (ozone, PM, CO, Pb, SO2, NO2) with primary/secondary standards.
- SIPs, NSPS, NESHAPs/MACT, Title V permits, NSR/PSD.
- Built on ambient outcomes, technology-based controls, permitting, and enforcement.
- No formal certification; compliance via permits, monitoring, reporting, audited by EPA/states.
Why Organizations Use It
Mandatory for emitters to avoid penalties, sanctions, citizen suits. Drives risk management, operational compliance, ESG benefits. Enables permitting agility, cost avoidance, market access.
Implementation Overview
Phased: gap analysis, permitting (Title V/NSR), controls/monitoring (CEMS), training/governance. Applies to stationary/mobile sources nationwide; major facilities require audits, electronic reporting. (178 words)
