The exam, which is based on the EC-Council’s Certified Ethical Hacker syllabus, tests you on 20 key domains. These include things like footprinting and reconnaissance (how hackers gather info about a target), scanning networks (finding vulnerabilities), enumeration (digging deeper into systems), system hacking (exploiting weaknesses), and malware threats (like viruses, worms, and trojans). You’ll also learn about social engineering – that’s when hackers trick people into giving up sensitive info, like through phishing emails – as well as denial-of-service attacks, session hijacking, and even how to hack web applications and wireless networks. It’s a broad, hands-on look at the tools and techniques hackers use, from sniffing network traffic to cracking passwords.
The CEH exam itself is a 4-hour, multiple-choice test with 125 questions. You need to score at least 70% to pass, and it’s not an easy ride – the questions are designed to test your real-world understanding, not just memorization. The EC-Council updates the exam regularly to keep up with new threats, so you’ll be learning cutting-edge stuff. Once you pass, you earn the CEH credential, which is globally recognized and respected in the cybersecurity industry. But here’s the catch: to maintain your certification, you’ll need to earn continuing education credits or retake the exam every three years. It’s their way of ensuring you stay sharp and up-to-date in a field that changes fast.Cloud Security Engineer Roadmap (Fundamentals, Career Path)Brendan Metcalfe2025-01-24 | A comprehensive look into cloud security.
