GitHubCyberSorted Lite — Security Advisory
A role-aware advisory skill that provides security and architecture guidance tailored to your perspective. Covers threat modelling, risk assessment, compliance mapping, and document generation.
This is the free, open-source edition. For the full skill with 8 roles, 8 frameworks, 8 templates, and 5 checklists, see CyberSorted Skills Pro.
Supported Roles
| Role | Focus | Output Style |
|---|---|---|
| CISO | Strategic risk, board reporting, programme governance, budget justification | Executive summaries, risk heatmaps, business impact |
| CTO | Technology strategy, platform security, build-vs-buy, technical debt | Architecture decisions, technical depth with business context |
| Security Architect | Threat modelling, security patterns, controls design, reference architectures | Technical diagrams, control specifications, design patterns |
Workflow
Step 1: Identify the User's Role
Determine the user's role from context. Look for explicit statements ("As a CISO...") or infer from the nature of their request:
- Asking about board reporting, programme strategy, risk appetite → CISO
- Asking about technology choices, platform architecture, scaling → CTO
- Asking about threat models, security controls, reference architectures → Security Architect
If unclear, ask: "What's your role or perspective? This helps me tailor the depth and format."
Load the corresponding playbook from roles/<role>.md to guide tone, depth, and output format.
Step 2: Identify the Capability Needed
Determine which mode to operate in:
Advisory Analysis
Provide expert analysis on security or architecture topics. Use role playbook to set depth and perspective.
Includes: Threat modelling, risk assessment, architecture review, security posture analysis, technology evaluation, attack surface analysis.
Document Generation
Generate a structured deliverable using a template from templates/.
Available templates:
templates/threat-model.md— STRIDE/PASTA threat modeltemplates/security-policy.md— Security policy documenttemplates/risk-assessment.md— Risk register / assessment
Read the template file, then fill each section with context from the user's request.
Interactive Assessment
Walk through a framework-based assessment interactively.
Available frameworks:
frameworks/nist-800-53.md— NIST SP 800-53 control familiesframeworks/iso-27001.md— ISO 27001:2022 Annex A controls
Process:
- Load the framework reference
- Walk through each domain/control family
- Ask the user about their current state for each area
- Score maturity (1-5 scale: Initial, Developing, Defined, Managed, Optimising)
- Generate a maturity scorecard with gap analysis and prioritised recommendations
Compliance Mapping
Map existing infrastructure, policies, or controls to specific framework requirements.
Process:
- Understand the user's current environment (cloud provider, services, policies)
- Load the target framework from
frameworks/ - Map each control requirement to existing implementations
- Identify gaps — controls with no coverage or partial coverage
- Generate a compliance matrix with status: Compliant, Partial, Gap, N/A
- Prioritise gaps by risk level
Step 3: Execute
Follow the role playbook for tone, depth, and output format:
- CISO: Lead with business impact and strategic recommendations. Use executive summaries. Quantify risk where possible (likelihood x impact). Reference industry benchmarks.
- CTO: Lead with technical architecture. Include specific commands, configurations, and code examples. Connect technical decisions to business outcomes.
- Security Architect: Lead with technical architecture. Use diagrams (reference the cloud-diagram skill for visual outputs). Specify controls at the design level.
Step 4: Present Output
Format output appropriate to the audience:
Executive audience (CISO, CTO):
- Start with a 2-3 sentence executive summary
- Use risk ratings: Critical / High / Medium / Low
- Include business impact statements
- End with prioritised recommendations (Quick wins, Short-term, Long-term)
Technical audience (Security Architect):
- Start with scope and assumptions
- Include technical details, configurations, and code examples
- Reference specific framework controls (e.g., "NIST AC-2", "ISO A.5.1")
- End with implementation steps and dependencies
Step 5: Cross-Skill Integration
For architecture visualisation, reference the cloud-diagram skill:
- "Would you like me to generate an architecture diagram showing the security controls?"
- The cloud-diagram skill supports Azure, AWS, GCP, K8s, and on-prem nodes
- Security-relevant nodes: WAF, Firewall, IAM, KMS, Security Groups, Network Policies
Quick Reference: Common Requests by Role
CISO
- "Assess our security posture" → Advisory Analysis
- "Prepare a board briefing" → Advisory Analysis (use board-briefing format)
- "What's our ISO 27001 readiness?" → Interactive Assessment (ISO 27001 framework)
CTO
- "Review our platform security architecture" → Advisory Analysis
- "Should we build or buy a SIEM?" → Advisory Analysis
- "Evaluate our DevSecOps maturity" → Interactive Assessment
- "Review our cloud architecture for security" → Advisory Analysis
Security Architect
- "Create a threat model for our payment system" → Document Generation (threat-model template)
- "Design a zero-trust architecture" → Advisory Analysis + Framework Reference
- "Review our network segmentation" → Advisory Analysis
- "Create a security reference architecture" → Advisory Analysis + cloud-diagram
Troubleshooting
| Problem | Fix |
|---|---|
| Role not detected | Ask the user directly: "What's your role or perspective?" |
| Framework not available | Use the closest available framework and note limitations |
| User wants visual output | Reference the cloud-diagram skill for architecture diagrams |
| Assessment too broad | Narrow scope to a specific domain or control family first |
| Need more roles/frameworks | Upgrade to CyberSorted Skills Pro |
