CyberVault.
Connect the dots.
A structured security reference for curious learners and practitioners. Move from a concept to a tool to its place in the bigger picture.
A reference that grows with you.
Keep your own copy, search it locally, and add your lab notes alongside the source material. The vault uses Markdown files and linked notes, ready to open in Obsidian.
Understand the concepts
Scope, attack surface, authentication, authorization, injection, identity, and more. Build a vocabulary you can put to work.
Know your tools
Purpose, practical usage, and context across reconnaissance, web testing, identity, password analysis, and network investigation.
Connect the workflow
A reference that brings the stages together, from the initial scope through evidence and reporting.
A reference you can actually read.
Explore a tool manual, a concept, and a field-note excerpt from the sample.
Nmap
Network discovery, port scanning, service detection, and NSE-based enumeration.
Practical examples
Run a focused authorized check.
nmap -sV -p 22,80,443 192.0.2.10Review the output, confirm the result, and retain only evidence relevant to the assessment.
Authorization
The decision process that determines which resources and actions an authenticated identity is permitted to access.
Decision model
A useful authorization decision can be expressed as:
subject + action + resource + context → allow or denyThe server must derive trusted attributes—identity, tenant, ownership, and role—from authoritative state rather than client fields.
Pentest Field Notes
A penetration test is not a race to run the largest number of tools. It is a controlled investigation: establish what may be tested, build an evidence-based model of the target, form hypotheses, test them with the least risky method, and explain the business consequence of what was proven.
The field mindset
The best testers repeatedly ask:
- What do I know?
- What am I assuming?
- What could connect these facts?
- What is the safest next test?
- What evidence would another person need?
