Does NIST expect implementing Zero trust?

NIST offers guidance for Zero Trust through SP 800-207, the CISA Zero Trust Maturity Model, and alignment with the Cybersecurity Framework.

NIST doesn't provide a set of strict requirements for Zero Trust implementation. However, their publications offer valuable guidance and principles that organizations can follow. Here's how NIST contributes to Zero Trust:

1. NIST SP 800-207: Zero Trust Architecture  This publication defines Zero Trust and outlines its core tenets. It emphasizes the principles of least privilege access, continuous verification, and dynamic authorization. While not a list of requirements, it provides a foundational understanding for building a Zero Trust architecture.
   

2. CISA Zero Trust Maturity Model This model, developed by the Cybersecurity and Infrastructure Security Agency (CISA) in collaboration with NIST, builds upon SP 800-207. It outlines five key pillars (Identity, Devices, Network/Data/Apps, Visibility/Analytics, and Governance) that organizations should focus on when implementing Zero Trust.  The model provides a maturity scale for each pillar, allowing organizations to assess their current state and plan improvement steps.
   

3. NIST Cybersecurity Framework (CSF) While not specific to Zero Trust, the NIST CSF provides a comprehensive framework for managing cybersecurity risk. Its core principles of Identify, Protect, Detect, Respond, and Recover align well with Zero Trust principles. Organizations can leverage the CSF to identify critical assets, prioritize controls, and continuously improve their overall security posture, which complements a Zero Trust approach.

In essence, NIST provides a knowledge base and guiding principles for Zero Trust implementation.  They don't dictate a specific set of requirements, but rather empower organizations to build a secure and adaptable security architecture based on their unique needs and context.

Conclusion

NIST is central to Zero Trust development, offering crucial guidance via SP 800-207 and collaborative efforts like the CISA Zero Trust Maturity Model. By aligning with the Cybersecurity Framework, NIST enables adaptable security strategies, empowering organizations to navigate evolving threats with resilience.
