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.

Domain 1: Information Security and Ethical Hacking Overview-6%
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.
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.

Types of ethical hacking:
Since virtually any system component may be hacked, there are several ethical 
hacking methods that need an in-depth understanding of that component. Below 
you’ll find a list of several ethical hacking techniques.
1.Web application hacking: Web hacking refers to the exploitation of HTTP 
applications by altering the application’s graphical web interface, tampering with 
the Uniform Resource Identifier (URI), or modifying HTTP components not present 
in the URI.
2.Social Engineering techniques: 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.
3.System hacking: 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.

4.Hacking wireless networks: 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.
5.Web server hacking: 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.
