The technique of discovering vulnerabilities in a
software, website, or agencys structure that a
hacker might exploit is known as ethical hacking.
They employ this method to avoid cyberattacks and
security breaches by legitimately hacking into
systems and looking for flaws. CEH was designed
to include a hands-on environment and a logical
procedure across each ethical hacking area and
technique. This is to provide you the opportunity
to work towards proving the knowledge and skills
to earn the CEH certificate and perform the tasks

Interview Questions 1. Describe hacking? Hacking
is the act of gaining access to a system or
network without authorization. A hacker is
someone who engages in this activity. They use
computers for malevolent purposes such as
invasion of privacy, theft of corporate and
individual data, and more. 2. Explain ethical
hacking? When someone performs penetration
testing or intrusion testing on behalf of the
owner of a software system, program, network, or
other computing resources, they are considered to
be ethical hackers because they are looking for
loopholes and vulnerabilities that a malevolent
hacker could use.

3. What are the different categories of
hackers?There are three categories of hackers,
each with a different goal and legality of the
action. Black Hat The black hat hackers are
responsible for creating malware. They obtain
unauthorized access to data or network, causing
it to be damaged and stealing critical
data. White Hat These are known as ethical
hackers. They are widely used by organizations or
government bodies to identify weaknesses. Grey
Hat The grey hat hacker is the combination of
both black and white hats, they find the weakness
of the network or device without the permission
or knowledge of the owner. Their objective is to
bring the systems vulnerabilities to the
customers attention and seek compensation or an
enticement from the owner. Besides these
well-known hackers, there are a variety of
hackers based on what they hack and how they hack

Website defacement or Denial-of-Service assaults
are common examples of hacktivism. Script
Kiddie The person who accesses a computer system
using automation tools written by others and has
little understanding of the fundamental concept,
known as Script Kiddie. Elite Hackers This is a
term used among hackers to describe the most
proficient hackers. Neophyte Theyre also known
as green hat hackers or beginner hackers because
they have no prior experience with technology or
hacking. Blue Hat Those who are not affiliated
with computer security consulting firms seek to
do a bug test on a system before its release to
identify flaws and plug gaps. Red Hat  They are
a hybrid of both white hat and black hat hackers,
and are typically engaged by top intelligence
services, government entities, and other firms
that handle sensitive data.

4. Explain different types of hacking? Hacking is
classified into the following types, based on the
category of being hacked Website hacking It
refers to unlawful access to a web server and its
connected software, such as databases and
interfaces, as well as the alteration of
data. Network hacking It refers to collecting
network data using tools such as Telnet, ping,
and so on, with the goal of serious harm to the
network and disturbing its functions. Email
hacking Email hacking means accessing customers
email accounts and utilizing them without
permission. Password hacking It is a process of
recovering secret passwords from data stored on
multiple platforms. Computer hacking Using

6. Explain various stages of hacking? Hacking is
divided into five stages Reconnaissance This
is the primary stage of hacking, also known as
the information gathering and footprinting phase.
In this stage, hackers collect as much as
information about the target. It includes
network, host, DNS records, and more. Scanning
It examines the network using the data collected
during reconnaissance. Achieving access The
stage in which attackers use various tools and
tactics to gain access to a system or
network. Keeping access open Once attackers have
gained access, they want to keep it for further
attacks and operations. This can be accomplished
through the use of malware, spyware, and other
malicious software. Covering tracks Once the
attackers have gained and maintained access, they
hide their traces to prevent identification. It
includes changing/deleting/corrupting the value
of logs, erasing all evidence of work,
uninstalling software, deleting files, and other
tasks.

7.What is the distinction between hashing and
encryption?
Hashing Encryption
Hashing is a technique for verifying the contents authenticity Hashing is a one-way function that converts plain text into an unchangeable unique sequence Whereas encryption ensures data privacy and security Encryption is a two-way process that encrypts and decrypts information




8. What exactly do you understand when you say
keystroke logging?Keystroke logging (sometimes
called keylogging or keyboard capturing) is a
technique for recording keystrokes. Its a form
of monitoring software that records every input
on the keyboard. Every keystroke is recorded, and
data is accessed by using the logging program.

9. What exactly do you mean by Trojan and how do
you classify them? A Trojan is a sort of malware
that is frequently created by hackers or
attackers to obtain access to target computers.
Users are tricked by some appealing social media
advertisements and then led to fake links, where
Trojans are loaded and run on their
devices. Types of Trojan Trojan downloader It
is a virus that downloads and installs other
viruses. Ransomware This type of malware
encrypts the data on your device/system. Trojan-dr
oppers These are advanced programs that
attackers utilize to install malware. Because
most antivirus products do not detect droppers as
dangerous, they are used to install
malware. Trojan banker These cybercriminals
collect user account information such as credit
card numbers and online banking
passwords. Trojan-backdoor It is the most common
sort of Trojan, and it builds a backdoor that
allows attackers to gain access to the machine,
later from a remote location using a Remote
Access Tool (RAT). This Trojan gives you complete
control over your computer.

  • 10. What exactly do you mean by
    exploitation?Exploitation is a feature of
    pre-programmed software or scripts that enable
    attackers to obtain control of the specified
    system/network and attack its vulnerabilities. To
    detect these vulnerabilities, most hackers
    utilize scanners such as OpenVAS, Nessus, and
    others.
  • 11. What exactly is enumeration in the context of
    ethical hacking?The first phase of ethical
    hacking is enumeration, which is information
    collection. During this phase, the attacker
    establishes an active connection with the target
    and attempts to gather as much data as possible
    to identify system vulnerabilities or weaknesses
    and further take advantage of the system.
    Enumeration gathers information on the following
    topics
  • Password policies list
  • IP tables
  • Network share
  • Username of different system
  • SNMP data

12. Describe MIB? The Management Information Base
(MIB) is a collection of network components that
are accessed remotely. It comprises all of the
technical specifications of the network objects
that a network management system is observing.
The MIB database object serves as a point of
reference for a comprehensive set of management
data on a network system. 13. What is
footprinting? Footprinting is a methodology for
gathering as much information about the specified
infrastructure as possible in order to carry out
a successful cyber operation. It also determines
the users defense capabilities. A hacker can
gather information about a domain name, IP
address, namespace, employee information, contact
information, mails, and employee data during this
period. It is divided into two parts Active
footprinting It collects data by direct contact
through the target network. Passive
footprinting It gathers data from a target
network that is located far away from the
attacker.

14. What exactly is DNS(Domain Name System) Cache
Poisoning? DNS cache poisoning is a method of
diverting internet traffic away from real servers
and towards misleading ones by exploiting DNS
flaws. DNS spoofing is another term for it. 15.
What exactly is a DDoS assault, and how does it
perform? Distributed Denial of Service(DDoS) is a
type of attack, where numerous affected systems
are frequently infected with a virus and
leveraged to target a single system, resulting in
a DoS (Denial of Service) attack. It is an
attempt to keep a webpage or online service
unavailable by flooding it with massive amounts
of traffic from several sources. 16. What
exactly is a phishing attack?Phishing is a
process or an attempt to get sensitive
information such as user data, credit card
numbers, and so on. These attacks usually happen
