A CEH (Certified Ethical Hacker) is a professional who typically works within a
Red Team environment. A Certified Ethical Hacker’s focus must be on attacking
systems and accessing applications, networks, databases, or other crucial
data on the secured systems. In addition to recognizing attack strategies and
exploiting creative attack vectors, a CEH can mimic the skills and creativity of
malicious hackers. Unlike black hat hackers, certified ethical hackers approach
systems with permission from their owners and maintain the confidentiality of
their work.
The job opportunities for a Certified Ethical Hacker are very high because of the
increasing cybercrimes. If you are interested in learning CEH, this blog is for
you. In this blog, you will get to know about all the domains of CEH certification.
Let’s dive into the topic.

The process of hacking involves finding vulnerabilities within a computer
system. In addition to stealing sensitive information, they can delete files and
perform other malicious activities using these vulnerabilities. It is illegal to
hack into computers, so you may face sanctions and be imprisoned for years
and years if caught. Nevertheless, hacking is legal when conducted with
permission. Usually, hackers are hired by owners of organisations to penetrate
their systems to discover vulnerabilities so that they can be remedied. Such
people who have access to your systems without any malicious intent are
called Ethical Hackers, and the process is called Ethical Hacking.
In this blog, we will discuss the 1st
domain of CEH,
which is ‘Information Security & Ethical

The importance of Ethical Hacking
The fundamental goal of an ethical hacker is to prevent sensitive data and
information from getting into the hands of cyber violators. It protects your
organisation from being threatened with extortion by individuals looking to
take advantage of the weaknesses.
The advantages of Ethical Hacking:
Organisations can find security flaws from an attacker’s point of view to
strengthen defenses.
> We can implement a secure network that blocks security violations.
> Ethical hackers can defend national security by preventing terrorists from
gaining access to sensitive information.
> We can gain the confidence of our consumers and investors by providing
secure products and data.

Social Engineering Techniques
DOMAIN 1
Information Security & Ethical Hacking Oveview
In social engineering, the goal is to manipulate others into disclosing sensitive
information. Criminals employ social engineering techniques because it is far
easier to take advantage of your inherent tendency to trust others than it is to
figure out how to hack your program or system.

System Hacking
DOMAIN 1
Information Security & Ethical Hacking Oveview
As a result of the penetration of computer systems and software, system
hacking allows the hacker to get control of the target machine and steal or
misuse the data on it. A malevolent hacker takes advantage of the flaws in a
computer system or network to get access to its data or benefit illegally.

Hacking Wireless Networks
DOMAIN 1
Information Security & Ethical Hacking Oveview
A wireless network is a collection of two or more devices connected by radio
waves within a restricted spatial range. Because wireless networks use radio
waves to communicate, an intruder may simply sniff the network from a
nearby place. Sniffing the network for SSID is a common attack technique used
by hackers.

Web Server Hacking
DOMAIN 1
Information Security & Ethical Hacking Oveview
A server-side software program generates web content in real-time. Hackers
use DoS (DDoS) assaults, SYN floods, ping floods, port scans, sniffer attacks, and
social engineering to steal credentials, passwords, and corporate information
from the web server.
