What is Certified Ethical Hacker (CEH)
The Certified Ethical Hacker (CEH) is a prestigious professional certification provided by the EC-Council. It’s designed for cybersecurity practitioners who are primarily responsible for securing information systems. A CEH is skilled in understanding and knowing how to look for weaknesses and vulnerabilities in target systems, using the same knowledge and tools as a malicious hacker, but in a lawful and legitimate manner.
The CEH certification verifies the candidate’s skills in ethical hacking (also known as penetration testing or white-hat hacking) and ensures they understand how to secure a system by assessing it for possible vulnerabilities. These vulnerabilities are usually exploited by attackers or malicious hackers to penetrate network systems and retrieve sensitive information.
A CEH-certified professional uses various hacking tools and techniques, but unlike a malicious hacker, they have legal permission to improve system security. The primary goal is to protect and secure the systems from attacks by fixing the vulnerabilities found during the testing.

What is the CEH Syllabus?
The CEH certification covers a wide array of topics, such as footprinting and reconnaissance, scanning networks, system hacking, social engineering, denial of service, session hijacking, hacking web servers, wireless networks, and web applications, and more. Candidates also gain practical, hands-on experience through labs that simulate a real-world environment. The syllabus includes the following:
1. Introduction to Ethical Hacking
Overview of different hacking methodologies, types of hackers, and various types of attacks.
2. Footprinting and Reconnaissance
This involves gathering information about a target. For instance:
whois domain.com // obtain domain registration information nslookup domain.com // obtain domain IP information
3. Scanning Networks
Identify live hosts, ports, and services that are running on the host.
nmap -sS -p 22,80,443 target.com // perform SYN scan
4. Enumeration
Extract further information from the network like routing paths, users/groups, etc.
net view \\target.com // enumerate network resources
5. Vulnerability Analysis
Identify vulnerabilities in the system.
nmap --script vuln target.com // check for vulnerabilities
6. System Hacking
Gaining access and maintaining access to the system.
john --format=descrypt passwordfile // crack passwords with John The Ripper
7. Malware Threats
Understand various types of malware, their functioning, and how to use antivirus tools.
8. Sniffing
Intercepting and logging traffic.
tcpdump -i eth0 // start packet capture
9. Social Engineering
Manipulation techniques that prompt individuals to make security mistakes.
10. Denial-of-Service
