Advance your career through Ethical Hacking. Ethical Hacking is a fascinating career opportunity for people who have excellent problem-solving skills and a passion for information security. It is the responsibility of ethical hackers to protect the essential infrastructure of the organization. Over the past several years, there has been a growing demand for ethical hackers in government agencies and private organizations. In order to become an ethical hacker, you need to be familiar with the network and hacking systems.
In this blog, we have provided some of the frequently asked Ethical hacking interview Questions. We have divided the frequently asked questions into basic, intermediate, and advanced levels. Let's get started with the basic level Ethical hacking interview questions for beginners.
Ethical Hacking is when an individual is permitted to hack the system with the owner of the product's permission to find a weakness in a system and then fix it. It is carried out by ethical hackers to evaluate and deliver a report based on the knowledge acquired during the hack.
Cybersecurity is about protecting computers and servers, electronic systems, mobile devices, networks, and data against malicious attacks. Cybersecurity is managed by cybersecurity experts who are responsible for protecting the system against malicious activity and attacks.
Hacking is divided into different types according to the category of being hacked:

Apart from these, there are other different types of hackers as well. They are Hacktivist, Script Kiddie, Elite Hackers, Neophyte, Red hat, Blue hat.

A network protocol is defined as a set of rules for determining how data transmissions occur among the devices within the same network. It mainly enables communication among connected devices irrespective of any differences in their design, internal structure, or processes. Network protocols are an essential component of digital communications.
Keylogger is a monitoring technique that an attacker uses on a target computer for recording and monitoring Keystrokes struck by the users. It records the sensitive information that the target has entered.
Network security is basically a set of rules and configurations designed to protect the confidentiality, accessibility, and integrity of computer networks and data using software or hardware technologies. Types of network security include:
Enumeration is the main step in ethical Hacking, which is the collection of information. At this stage, the attacker establishes an active connection with the victim and attempts to get much information to identify vulnerabilities or weaknesses in the system and attempt to make further use of it. Enumeration captures information related to IP tables, Network shares, password policy lists, Usernames of various systems, and SNMP data if incorrectly secured.
Cowpatty is a tool implemented on an offline dictionary-based attack over WPA/WPA2 networks that utilize PSK-based authentication. Cowpatty may perform an improved attack if a recalculated PMK document is available to the SSID being evaluated.
System sniffing involves the use of sniffing tools that enable real-time monitoring and analysis of data streams on PC systems. Sniffers can be used for a wide range of purposes, from data theft to systems management. Network sniffing is used for ethical as well as unethical purposes. System administrators use them as a tool to monitor and analyze the system in order to analyze and avoid network problems, such as traffic bottlenecks. Cyber Criminals use these devices for unreliable purposes, such as character usurpation, email, hacking sensitive information, and so on.
Footprinting is the accumulation and discovery of so much information on the target network prior to accessing a network. It is the approach of hackers before hacking the target network.
Phishing is a type of attack where attackers create an emergency through the use of threats, financial incentives, and impersonating an authoritative organization to ask a user to submit sensitive information, like usernames and passwords, credit card details, etc.
In other words, Phishing is the effort to steal sensitive information like user data, credit card numbers, etc. Such attacks mainly occur through the use of personal social networking sites, email accounts, online transactions, etc.
Spoofing is a fraud that involves impersonating a legitimate source or someone known to the target to obtain sensitive information. Hackers may use that information to carry out illegal activities like identity theft. Some of the more popular spoofing attacks include:
ARP refers to the Address Resolution Protocol. It is a type of attack where an attacker changes the Media Access Control (MAC) address and attacks an Internet LAN by modifying the ARP cache of the target computer with a fake ARP query and reply packets. ARP spoofing is also called ARP poisoning. ARP poisoning can be avoided using the following methods.
CSRF refers to Cross-site request forgery. This is an attack from a malicious website which sends a request to a Web application against which a user is already authenticated from another Web site. To avoid CSRF, you can add an unpredictable challenge token to every request and link them to the user's session. They ensure the developer that the requests they received are from a valid source.
MIB refers to Management Information Base. It is a virtual database. It includes all formal network object descriptions that are controlled by a network management system. It is used to refer to a full collection of management information about an entity such as a computer network.
Mac Flooding is one technique in which the security of a particular network switch is compromised. In this technique, the hacker floods the switch with a lot of frames, then what it can manage. It makes the switch behave like a hub and sends all packets to all ports. Using this, the attacker will attempt to send their package within the network for stealing sensitive data.
Some of the password cracking techniques include:
SQL injection is a way to hack a Web application. In this method, the attacker runs malicious SQL commands to gain control over the database server. Attackers are using SQL vulnerabilities to recover or change SQL data.
Types of SQL injections are as follows:
DOS attacks involve the flooding of servers, networks, or systems with traffic to cause overconsumption of resources of victims. As a result, legitimate users have difficulty accessing or using targeted sites.
DOS attacks include the following:
DDOS refers to Distributed Denial of Services. It is an attack that involves an attacker flooding a network, website, or server with unnecessary traffic for it to become unserviceable to the intended user. Traffic may include incoming connection requests or false data packets. There are three kinds of DDOS attacks.
By adopting the following method, we can prevent our website from being hacked:
Fingerprinting is a technique used to determine an operating system that operates on a remote computer. There are two types of fingerprinting techniques.
It is a technique which uses vulnerabilities in the domain name system to redirect Internet traffic from legitimate and fake servers. It is also referred to as DNS spoofing.
It is a DHCP server that is configured on a network by an attacker who is not controlled by the network admins. Maybe it's a modem or a router. Rogue DHCP servers are mainly used by hackers for network attacks like Reconnaissance, Sniffing, and Man in the Middle.
Burp Suite is a built-in platform used to perform a web application security test. It comprises a variety of tools that work perfectly together to handle the complete testing process, from initial mapping to security vulnerabilities. It includes all the tools that hackers would need to attack any application like spider, proxy, scanner, intruder, decoder, repeater, comparer, sequencer.
A penetration test is also called a pen test. It simulates a cyberattack on a computer to verify possible vulnerabilities within the system. It is usually implemented to enhance a Web Application Firewall. It may involve a simulated attack on a number of application systems like front-end servers, back-end servers, and APIs to find out all the vulnerabilities present. The information acquired through this test is used to tighten WAF security policies and solve detected problems. Some of the most commonly used tools in penetration testing include:
