5 Worldbuilding
Effective cybersecurity case studies require believable, consistent fictional worlds where students can engage with complex security challenges. This chapter provides practical guidance for creating systematic worldbuilding frameworks using YAML-based data management that scales across multiple case studies.
The centralized _worldbuilding.yml
approach demonstrated in the tutorial enables consistent character development, organizational structures, and technical environments while maintaining narrative coherence across your entire case study collection.
Why Systematic Worldbuilding Matters
Consistent worldbuilding provides several critical benefits for cybersecurity education:
Student Engagement: Students connect more deeply with realistic characters and organizations they can believe in
Technical Authenticity: Systematic data management ensures accurate representation of cybersecurity tools, processes, and organizational structures
Scalable Development: Centralized world data enables efficient creation of multiple related case studies
Cross-Case Continuity: Shared characters and organizations create interconnected learning experiences that reinforce key concepts
Setting Up Your Worldbuilding System
The _worldbuilding.yml
file serves as your central data repository for all fictional world elements. This systematic approach ensures consistency across multiple case studies while enabling dynamic content generation.
Basic YAML Structure
Start with this foundational _worldbuilding.yml
template. We’ll start with fully manual work. You can automate the creation of the year_plus_#
values in the setup script to generate accurate and dynamic dates as far forward or back as you like. We’ll presume there’s just one single case study for this example. When describing multiple, cross-linked cases, prefixing values with casename_
is suggested.

client_size: "1,200 employees"
client_location: "Phoenix, Arizona"
# Technical Environment
primary_network: "10.0.0.0/16"
dmz_network: "192.168.100.0/24"
vpn_solution: "Cisco AnyConnect"
firewall_vendor: "Palo Alto Networks"
# Incident Details
incident_type: "Advanced Persistent Threat"
incident_discovery_day: "March 15" # Couple with world$year_plus_1 for next year
incident_duration: "72 hours"
systems_affected: 145
records_compromised: "~50,000 patient records" # Useful for writing news stories
# Financial Impact
direct_costs: "$2.3 million" # Easily increase or decrease

business_interruption: "$1.2 million"
# Regulatory Context
primary_regulation: "HIPAA"
notification_deadline: "60 days"
reporting_authority: "HHS Office for Civil Rights"
Choose consistent naming conventions early. Use underscores for YAML keys (company_name
) and establish clear patterns for character references (cto_name_last
, ceo_name_salutation
).
This allows for text like “`r world$ceo_name_salutation`
`r world$ceo_name_last`
.” to render as “Ms. Drum-Butcher.”
Advanced: Developing Characters and Organizations
Character Development Framework
Effective cybersecurity case studies require believable characters with realistic professional backgrounds and motivations. Expand your _worldbuilding.yml
with detailed character information if you wish to have more nuanced and documented character development. While you may use this information in your case content, it is more useful for AI-analysis of your world for consistency’s sake. Remember: _worldbuilding.yml
can arbitrarily organized so long as the YAML syntax is valid.
Example:
# Character Relationships and Dynamics
relationships:
sarah_and_marcus:
type: "Professional colleagues"
history: "Worked together at previous company for 3 years"
dynamic: "Collaborative leadership style"
aisha_and_alex:
type: "Mentor-mentee"
history: "Aisha hired Alex directly from bootcamp"
dynamic: "Supportive but demanding training relationship"
# Character Motivations and Goals
character_motivations:
ceo:
primary: "Building company reputation in competitive market"
secondary: "Proving women can lead in cybersecurity"
fear: "Losing client trust due to preventable incidents"
junior_analyst:
primary: "Proving competence in first professional role"
secondary: "Learning from experienced professionals"
fear: "Making mistakes that compromise client security"
Base character backgrounds on realistic career paths. Research actual cybersecurity roles, typical experience levels, and common certification progressions to create believable professional personas.
Organizational Structure and Context
Create detailed organizational frameworks that support complex cybersecurity scenarios:
You cannot have YAML keys include other YAML keys for inline R rendering. In the example below, it would be tempting to set the company head to head: world$ceo_name-last
but this will not work. Your own personal organization of worldbuilding content will be unique depending on what you want to highlight or focus on. If you’re interested in a focus on organizational structures, then perhaps the example below is best. I’ve blown out the head of the Executive Leadership department to use the same modular naming conventions as earlier just for demonstration. You could then refer to `world$company_structure$departments$exec_leadership$head_last`
to get “Drum-Butcher,” or `world$client_portfolio$healthcare$average_size`
to insert “500-2000 employees.” This, however, is an advanced approach and isn’t necessary for a successfully designed case study.
# Company Structure and Departments
company_structure:
departments:
exec_leadership:
dept_name: "Executive Leadership"
head_last: "Drum-Butcher"
head_first: "Sarah"
head_salutation: "Mrs."
staff_count: 3
budget: "$2.5M annually"
soc:
dept_name: "Security Operations Center"
dept_abbr: "SOC"
head_last: "Patel"
head_first: "Aisha"
head_salutation: "Dr."
staff_count: 45
specializations: ["SOC Operations", "Incident Response", "Threat Intelligence"]
shift_structure: "24/7 coverage"

average_size: "800-3000 employees"
common_challenges: ["OT/IT convergence", "Supply chain security", "Industrial espionage"]
revenue_percentage: "10%"
Technical Infrastructure and Authenticity
Technology Stack Development
If your focus is on technical applications and implementations, you may wish to provide specific technical specifications. In this situation, ground your case studies in realistic technical environments. Document specific tools, systems, and configurations. Note that you can even add markdown to these, such as the access_switches
below:
# Detailed Technical Environment
technical_environment:
network_architecture:
core_switches: "Cisco Catalyst 9500 Series"
access_switches: "[Cisco Catalyst 9300 Series](https://cisco.com)"
wireless_controller: "Cisco WLC 5520"
network_segmentation: "VLANs for guest, corporate, and secure zones"
security_infrastructure:
firewall: "Palo Alto Networks PA-5220"
endpoint_protection: "CrowdStrike Falcon Complete"
email_security: "Proofpoint Email Protection"
web_filtering: "Zscaler Internet Access"
vulnerability_scanner: "Tenable Nessus Professional"
siem_solution: "Splunk Enterprise Security"
cloud_environment:
primary_provider: "AWS"
regions: ["us-west-2", "us-east-1"]
key_services: ["EC2", "S3", "RDS", "CloudFront", "IAM", "CloudTrail"]
backup_strategy: "Multi-region replication with 30-day retention"
# Attack Methodology (MITRE ATT&CK Framework)
attack_scenario:
initial_access:
tactic: "T1566 - Phishing"
technique: "T1566.002 - Spearphishing Link"
target: "Finance department staff via LinkedIn connection"
success_rate: "3 of 15 recipients clicked malicious link"
execution:
tactic: "T1059 - Command and Scripting Interpreter"
technique: "T1059.001 - PowerShell"
payload: "Obfuscated PowerShell script downloaded from compromised site"
persistence:
tactic: "T1053 - Scheduled Task/Job"
technique: "T1053.005 - Scheduled Task"
location: "Primary domain controller"
frequency: "Every 4 hours during business hours"
lateral_movement:
tactic: "T1021 - Remote Services"
technique: "T1021.001 - Remote Desktop Protocol"
method: "Compromised administrator credentials"
affected_systems: "15 workstations, 3 servers"
Verify all technical details against current industry standards. Outdated technology references can undermine case study credibility and educational value.
Timeline Management and Consistency
Relative Date Systems
Use relative date references to maintain timeline consistency across case studies. Note that you cannot reference a YAML key in another YAML key.
# Flexible Timeline Framework
timeline:
company_founding: "year_minus_6" # DOES NOT WORK!
company_founding: 2019 # Use year_minus_6 in the document
# Specific Incident Timeline
incident_progression:
initial_compromise: "March 15, 2025, 9:23 AM"
first_detection: "March 17, 2025, 2:15 PM"
escalation_to_leadership: "March 17, 2025, 3:45 PM"
containment_achieved: "March 18, 2025, 11:30 PM"
forensic_analysis_complete: "March 22, 2025, 4:45 PM"
systems_recovery: "March 25, 2025, 8:00 AM"
lessons_learned_session: "April 2, 2025, 10:00 AM"

Integrating World Data into Case Studies
Basic Variable Substitution
Reference your _worldbuilding.yml
data directly in case study QMD files using inline R code:
On `r world$incident_discovery_day`, `r world$this_year`, `r world$company_name` discovered
a security breach affecting `r world$client_name`. The incident was
initially detected by `r world$junior_analyst_job_title` `r world$junior_analyst_name_first`
`r world$junior_analyst_name_last`, who noticed unusual network traffic patterns
during routine monitoring.
Renders as:
On March 15, 2025, CyberSecure Technologies discovered a security breach affecting Regional Medical Center. The incident was initially detected by Junior Analyst Alexander Kim, who noticed unusual network traffic patterns during routine monitoring.
Complex Narrative Integration
Build detailed scenarios using multiple world data elements:
## Executive Response
`r world$ceo_name_salutation` `r world$ceo_name_last`, with her background as a `r world$ceo_background`,
immediately recognized the severity of the situation. Having faced
similar challenges during her previous role, she knew that the next
`r world$incident_duration` would be critical for both
`r world$company_name`'s reputation and `r world$client_name`'s
operational continuity.
The financial implications were substantial. Initial estimates suggested
direct response costs of `r world$direct_costs`, with potential
regulatory fines under `r world$primary_regulation` reaching
`r world$regulatory_fines`.
Dynamic Content with Conditional Logic
Create adaptive narratives based on character attributes:
# R code chunk for conditional content
if (world$junior_analyst_experience == "6 months") {
experience_desc <- "relative newcomer to the field"
confidence_level <- "cautious but eager"
decision_speed <- "carefully considered"
} else {
experience_desc <- "well-experienced professional"
confidence_level <- "confident and decisive"
decision_speed <- "quickly made"
}
Calculated Values and Financial Impact
Generate dynamic calculations for realistic financial scenarios:
# Calculate total incident costs
direct_cost_num <- as.numeric(gsub("[^0-9.]", "", world$direct_costs))
regulatory_fines_num <- as.numeric(gsub("[^0-9.]", "", world$regulatory_fines))
business_interruption_num <- as.numeric(gsub("[^0-9.]", "", world$business_interruption))
total_cost <- direct_cost_num + regulatory_fines_num + business_interruption_num
total_cost_formatted <- paste0("$", format(total_cost, big.mark = ","), " million")
# Calculate percentage of annual revenue (assuming $25M annual revenue)
revenue_percentage <- round((total_cost / 25) * 100, 1)
Quality Assurance for Worldbuilding
Systematic Consistency Checking
Implement regular validation processes to maintain worldbuilding integrity:
Character Audit Checklist
Technical Validation Framework
Validation Area | Check Points | Frequency |
---|---|---|
Network Architecture | IP ranges don’t conflict, logical subnetting | Per case study |
Security Tools | Current versions, realistic configurations | Quarterly |
Attack Techniques | MITRE ATT&CK alignment, current TTPs | Bi-annually |
Regulatory Requirements | Updated compliance standards, penalty amounts | Annually |
Timeline Feasibility | Incident progression, response timeframes | Per case study |
Content Review and Validation Process
Phase 1: Internal Review
- Cross-reference all character details for consistency

executive_leadership:
example_personas: ["ceo", "cto", "board_member"]
core_competencies: ["business_strategy", "resource_allocation", "crisis_management"]
learning_trajectory: "reactive_to_proactive_governance"
Role-Based Character Architecture: This methodology uses role-based character references rather than specific character names to maximize educational flexibility and transferability. This approach enables:
- Institutional Adaptation: Educators can map roles to their own character systems or local contexts
- Learning Objective Alignment: Focus remains on competency development rather than specific personas
- Methodological Transferability: The framework applies across diverse educational settings and character universes
- Maintenance Simplicity: Updates to specific character names don’t impact the underlying pedagogical structure
The character_role_mapping
section demonstrates how educators can implement their own character systems while maintaining pedagogical coherence across case sequences.
