About this course

Defenders who understand offensive techniques build stronger systems. This course introduces the methodology professional penetration testers use — always within legal, authorised boundaries — and shows how each technique informs better defence.

In isolated practice labs you will map networks, identify vulnerable services, analyse web application weaknesses and then fix what you find. Each lab ends with a short report, the key deliverable in real security assessments.

What you'll learn

  • Explain the legal and ethical rules of security testing
  • Map networks and services in a lab environment
  • Assess systems for common vulnerabilities
  • Understand the OWASP Top 10 web application risks
  • Harden systems based on assessment findings
  • Write clear, actionable security reports
