Abstract
The cybersecurity landscape continues to evolve rapidly with the integration of Generative AI and Large Language Models (LLMs) transforming penetration testing methodologies. This roadmap provides a structured approach to becoming an ethical hacker, covering foundational security principles like defense in depth and secure by design, alongside practical aspects including network security, endpoint protection, and incident response.
Modern ethical hacking now incorporates AI tools for automated vulnerability scanning and analysis, while addressing ethical concerns, skill gaps, and data privacy risks. This guide emphasizes continuous learning, certifications, and community engagement as essential elements for success in this dynamic field.
