The National Institute of Standards and Technology (NIST) has released a new guide, SP 1800-35, titled "Implementing a Zero Trust Architecture," aimed at providing practical assistance in building zero trust architectures (ZTA). This guidance includes 19 example setups that utilize commercially available, off-the-shelf tools. The initiative is a result of work conducted by NIST’s National Cybersecurity Center of Excellence (NCCoE).
Over the course of four years, NIST collaborated with 24 industry partners, including major tech companies, to build, install, test, and document the 19 ZTA models. These models illustrate various real-world scenarios such as hybrid cloud setups, branch offices, and even public Wi-Fi use in coffee shops. Each model provides technical details on deployment, sample configurations, integration steps, test results, and best practices derived from real-world experiences. The guide also maps these setups onto NIST's broader cybersecurity framework (CSF), SP 800-53 controls, and critical software measures.
The rise in popularity of zero trust architectures comes as traditional on-prem security perimeters weaken due to the increasing adoption of cloud services, mobile devices, remote employees, and IoT devices. The new NIST guidance builds on its earlier zero trust framework, SP 800-207, by providing more hands-on implementation advice. According to Brian Soby, CTO at AppOmni, one of the main challenges in real-world zero trust implementations is the existence of multiple policy decision and policy enforcement points, which are often left out of many zero trust plans, potentially leaving doors open for attackers. This new guidance recognizes the reality of multiple PDP/PEPs and operationalizes the concept of Policy Information Points, enhancing decision-making within the architecture by adapting to changing context and user behaviors.
