What does the Trusted Computer System Evaluation Criteria Toolkit include?

The Trusted Computer System Evaluation Criteria Toolkit includes 240 assessment questions across all TCSEC security classes (D through A1), 18 editable policy templates (Word), 7 implementation playbooks, a TCSEC-to-NIST SP 800-53 crosswalk (Excel), 3 gap analysis matrices (Excel), and a 65-page implementation guide (PDF). All files are available for instant digital download in PDF, DOCX, and XLSX formats, providing a complete resource for evaluating, documenting, and improving compliance with the TCSEC Orange Book standard.

The Trusted Computer System Evaluation Criteria Toolkit delivers a complete, standards-aligned framework to assess, document and improve your organisation's information security posture against rigorous evaluation benchmarks, ensuring compliance with the Trusted Computer System Evaluation Criteria (TCSEC), commonly known as the Orange Book. Without a structured approach, organisations risk failing independent audits, exposing critical systems to unauthorised access, incurring regulatory penalties, and losing stakeholder trust due to demonstrably inadequate security controls. With this toolkit, you gain immediate access to ready-to-use assessment instruments, policy templates and implementation guidance that align with TCSEC's hierarchical security classification levels (D, C1, C2, B1, B2, B3, A1), enabling you to systematically validate technical and administrative controls, close compliance gaps, and demonstrate due diligence in securing sensitive computing environments.

What You Receive

  • A comprehensive 240-question TCSEC maturity self-assessment (PDF and Excel), organised across seven security classes and 12 core domains including discretionary access control, mandatory access control, object reuse protection, trusted path mechanisms, audit logging, system architecture, and reference monitor implementation, enabling you to score current capabilities and identify priority remediation areas
  • 18 fully customisable policy and procedure templates (Word format) mapped to TCSEC requirements, covering trusted facility manual development, configuration management, trusted recovery, covert channel analysis, and labelling of sensitive data, reducing drafting time by up to 70% while ensuring technical accuracy
  • 7 detailed implementation playbooks (one per TCSEC class), each providing step-by-step workflows, system design checklists, trusted computing base (TCB) boundary definitions, and configuration benchmarks, so you can plan incremental upgrades from minimal protection (D) to verified design (A1)
  • A TCSEC-to-NIST SP 800-53 crosswalk dataset (Excel), enabling comparison between legacy Orange Book controls and modern cybersecurity frameworks, critical for organisations modernising legacy systems while maintaining compliance traceability
  • 3 editable gap analysis matrices (Excel) that map your current system configuration against required features for each TCSEC level, calculate maturity scores, and auto-generate prioritised remediation roadmaps, helping you justify investment in security enhancements
  • A 65-page implementation guide (PDF) explaining how to conduct a formal TCSEC evaluation, prepare for technical reviews, document system architecture, and satisfy evidence requirements for each class, so you avoid rework during assessment cycles
  • Access to all files via instant digital download in industry-standard formats: PDF, Word (.docx), and Excel (.xlsx), ready for immediate use across your security, audit, and engineering teams

How This Helps You

Using the Trusted Computer System Evaluation Criteria Toolkit, you transform an otherwise complex, high-risk compliance obligation into a structured, repeatable process. Each assessment question and template is derived directly from the original TCSEC standard (DoD 5200.28-STD), ensuring technical fidelity and audit defensibility. You can rapidly evaluate whether your operating system, database, or network infrastructure meets formal security policy models like Bell-LaPadula, enforce least privilege through granular access controls, and produce documentation that satisfies stringent review requirements. Without this toolkit, organisations often underestimate the depth of technical evidence required, resulting in failed evaluations, project delays, and continued exposure to unauthorised data access. By contrast, users of this toolkit consistently reduce preparation time by 50%, align cross-functional teams around a common compliance target, and increase the likelihood of first-time evaluation success, protecting contracts that require certified systems, avoiding non-compliance penalties, and strengthening customer confidence in your security posture.

Who Is This For?

  • Information security managers responsible for achieving or maintaining formal certification of critical systems against government or defence-grade security standards
  • Compliance officers in regulated sectors (defence, aerospace, critical infrastructure) who must demonstrate adherence to legacy evaluation criteria during audits
  • IT risk assessors conducting gap analyses on existing systems to determine TCSEC alignment and roadmap upgrade paths
  • Security architects designing high-assurance computing environments requiring verified protection mechanisms and trusted system components
  • Government contractors preparing systems for evaluation under national information assurance programmes that reference TCSEC or Common Criteria
  • Cybersecurity consultants delivering assurance services and needing standardised, citable assessment tools for client engagements

Choosing the Trusted Computer System Evaluation Criteria Toolkit is not just a purchase, it’s a strategic decision to eliminate ambiguity, accelerate compliance, and position yourself as a technically rigorous, outcome-focused professional capable of delivering auditable security results.
