- Automation and Orchestration: Automation of safety responses to scale back human error and enhance velocity.
Implementation and Guidance
CISA Zero Trust Maturity Model Capabilities
Implementation: Provides businesses with a maturity mannequin to trace their progress (e.g., conventional, superior, and optimum Zero Trust maturity ranges).
Guidance: Encourages businesses to undertake industrial applied sciences and observe finest practices for securing methods incrementally.
Focus Areas:
- Identity and entry administration (IAM) with multi-factor authentication (MFA).
- Network segmentation for isolating delicate methods.
- Data encryption and monitoring.
DoD Zero Trust Strategy Capabilities
Implementation: Requires strict compliance with the DoD Cybersecurity Maturity Model Certification (CMMC) for contractors and adherence to mission-critical safety requirements.
Guidance: Mandates defense-grade instruments, applied sciences, and protocols (e.g., categorised communication networks, superior menace looking, and insider menace prevention mechanisms).
Focus Areas:
- Advanced adversary techniques comparable to nation-state threats.
- Secure operational know-how (OT) and weapons methods.
- Integration with defense-specific applied sciences like safe satellite tv for pc communications and categorised knowledge methods.
Risk Tolerance and Flexibility
CISA Zero Trust Model Capabilities
Risk Tolerance: Designed for environments with various ranges of danger tolerance. Encourages incremental adoption and adaptability based mostly on company maturity.
Flexibility: A broad and adaptable framework for various organizations, together with these with restricted assets.
DoD Zero Trust Strategy Capabilities
Risk Tolerance: Operates with a near-zero danger tolerance as a result of essential nature of protection operations. Focuses on eliminating single factors of failure and securing your complete ecosystem.
Flexibility: Minimal flexibility as a result of inflexible necessities for nationwide protection and mission assurance.
Similarities and Differences Summary
To assist visualize the place these frameworks align – and the place they diverge – Table 1 summarizes the important thing similarities and distinctions between the 2.
| Category | CISA Five Pillars of Zero Trust | DoD Seven Pillars of Zero Trust | Key Insights |
| Identify | Identify | User (Identity) | Both emphasize securing consumer identification, authentication, and entry management based mostly on identification verification. |

Key Observations:
Similarities
Both frameworks share a typical basis in securing identification, units, networks, functions/workloads, and knowledge. They additionally emphasize the core rules of Zero Trust: “never trust, always verify,” least privilege entry, and steady monitoring. Aligned with NIST 800-207, each use its rules as a basis. While they share related pillars comparable to Identity, Device, Network, and Data, the DoD provides extra particular classes (e.g., Visibility and Automation).
NIST Special Publication 800-207, titled Zero Trust Architecture (ZTA), is a framework printed by NIST that gives tips for implementing Zero Trust rules in IT methods. The doc serves as a foundational useful resource for organizations aiming to modernize their cybersecurity defenses and cut back the danger of knowledge breaches and unauthorized entry.
