Think like an ethical tester
Start with permission, build a lab, and turn findings into improvements. Follow the sequence or open any note that catches your interest.
Permission & preparation
- 01
Rules of engagement
Define exactly what testing is authorized and how to handle unexpected events.
- 02
Virtual security labs
Create an isolated environment for learning without exposing vulnerable systems.
- 03
Kali Linux
A tool distribution is a platform for authorized work, not a substitute for fundamentals.
Explore the surface
- 04
Reconnaissance
Build a target model before choosing active assessment steps.
- 05
Port scanning
Observe service reachability from one network position at one time.
- 06
HTTP and HTTPS
Understand HTTP requests, methods, responses, and status codes while separating web semantics from encryption and application authorization.
Validate & report
- 07
OWASP Top 10
Use the OWASP Top 10:2025 as a versioned awareness guide, then turn relevant categories into application-specific requirements and evidence.
- 08
DVWA
A deliberately vulnerable application for isolated, authorized learning.
- 09
Reporting security assessments
Translate a controlled finding into a fix that an owner can validate.
Keep connecting the dots.
