Helping security teams and training platforms publish hands-on cybersecurity content that engineers actually learn from.
I’m Collin Little, a cybersecurity technical writer and lab developer specializing in Linux hardening, authentication systems, vulnerability analysis, and blue team tooling.
My work focuses on lab-driven technical content — breaking down complex security systems through real experiments, command-line walkthroughs, and reproducible labs.
This approach helps security teams and learners understand how systems behave in practice, not just in theory.
Technical Security Articles
Deep-dive blog posts and tutorials designed for engineering audiences.
Typical topics include:
- Linux hardening and system security
- PAM authentication and account security
- vulnerability scanning workflows
- authentication and authorization flaws
- web application security fundamentals
Typical deliverables include:
- diagrams or architecture explanations where helpful
- 1500–3000 word technical articles
- command-line demonstrations and configuration walkthroughs
Hands-On Security Labs
Interactive training environments designed for learning platforms and internal security training.
Deliverables may include:
- lab environment design
- challenge scenarios
- step-by-step walkthroughs
- solution guides and instructor notes
These labs simulate real-world security scenarios in controlled environments.
Security Playbooks & Documentation
Operational documentation designed for security teams.
Examples include:
- Linux hardening procedures
- incident response playbooks
- detection engineering workflows
- vulnerability scanning processes
Content is written to be clear, structured, and immediately actionable.
Writing Samples
Examples of my work:
- Linux Hardening Guide – Securing the User Jungle
- Passbolt Deployment & Configuration
- Nessus Vulnerability Scanning Walkthrough
- PortSwigger Web Security Lab Analysis
