112-51

The EC-Council 112-51 exam, Certified Ethical Hacker (CEH), is a globally recognized certification that validates your knowledge and skills in ethical hacking. It covers a wide range of topics, but the main points can be categorized as follows:

1. Footprinting and Reconnaissance:

• Gathering information about a target organization through open sources like social media, websites, and public records.
• Understanding different techniques like whois lookup, DNS enumeration, and Google hacking.

2. Scanning and Enumeration:

• Identifying live systems and services on a target network.
• Understanding various scanning tools like Nmap, Nessus, and OpenVAS.
• Discovering vulnerabilities like open ports, outdated software, and misconfigurations.

3. Vulnerability Analysis and Exploitation:

• Identifying and assessing vulnerabilities in software and hardware.
• Understanding common vulnerability categories like buffer overflows, SQL injection, and cross-site scripting (XSS).
• Exploiting vulnerabilities to gain unauthorized access to systems.

4. System Hacking:

• Understanding various methods for gaining access to operating systems, including password cracking, privilege escalation, and backdoor installation.
• Learning about different operating systems like Windows, Linux, and macOS.

5. Network Hacking:

• Understanding how to compromise network devices like routers, switches, and firewalls.
• Learning about different network protocols like TCP/IP, UDP, and ICMP.
• Knowing how to launch network attacks like denial of service (DoS) and man-in-the-middle (MITM).

6. Web Hacking:

• Understanding how to exploit vulnerabilities in web applications.
• Learning about various web technologies like HTML, CSS, JavaScript, and PHP.
• Knowing different web attack techniques like SQL injection, cross-site scripting (XSS), and session hijacking.

7. Cryptography:

• Understanding different encryption and decryption algorithms like AES, DES, and RSA.
• Learning about cryptography concepts like hashing, digital signatures, and key management.

8. Social Engineering:

• Understanding how to manipulate people to gain access to information or systems.
• Learning about different social engineering techniques like phishing, baiting, and pretexting.

9. Malware and Virus Analysis:

• Understanding different types of malware like viruses, worms, and trojans.
• Learning about malware analysis techniques and tools.
• Knowing how to identify, analyze, and remove malware from systems.

10. Legal and Ethical Considerations:

• Understanding the legal and ethical implications of hacking.
• Learning about different laws and regulations related to cybersecurity.
• Knowing the importance of ethical hacking and how to conduct it responsibly.

11. Countermeasures and Security Tools:

• Learning about security tools for intrusion detection and prevention.
• Understanding how to configure and deploy security tools.
• Knowing how to implement countermeasures against common attacks.

Overall, the CEH exam emphasizes practical skills and the ability to think like a hacker. It teaches you how to identify vulnerabilities, exploit them, and then use that knowledge to secure systems and networks.
