Top 50 Interview Questions/Answers for Ethical Hackers (2022)

A good understanding of ethical hacking interview questions will help you build a successful career in cybersecurity. Here are some:

The following (Ethical hacking interview questions) CEH questions and answers cover the basics Of Ethical Hacking:

1. Define ethical hacking.

Some hobbyist hackers started using this term to identify vulnerabilities in networks when they helped organizations. It is also called Whitehat hacking. Its main goal is to find and exploit security vulnerabilities in the target system and ethically report these loopholes to the responsible organizations. People who do ethical hacking are called ethical hackers or white hat hackers.

2. Why are ethical hackers in such high demand? 

In this growing digital world everyone is using the internet, almost every company uses the internet to give their services to users like we can book flights, trains, movie tickets online just by visiting a single website or by downloading an app into our phone. So this growing world of the internet has become a target of some bad people who are called “Black hat hackers”, they hack into companies and steal the user's data and other confidential information’s, to protect those data from being stolen organization’s hire ethical hackers, however, there is lack of security professionals in this domain and bad people continuously banging onto the door’s of organizations or breaking into it. That’s why there is a high demand for ethical hackers.

3. Define black hat hackers.

Black hat hackers are those who break into an organization’s networks and steal confidential information’s and leak them into the internet. They do this for money, personal reasons, political agenda, etc.

4. What are the differences between grey hat hackers and black hat hackers?

Gray hat hackers are those who do both things white hat hacking and black hat hacking, they do black hat stuff for personal reasons or money. 

Black hat hackers are those who do illegal things such as breaking into systems and breaching the security of organizations.

5. Define white hat hackers.

They focus on strengthening security systems by using ethical hacking techniques. The white hat hackers are never intended to cause harm. The majority of ethical hacker interview questions pertain to white hat hackers when you apply for an ethical hacker position.

6. Define SQL Injection.

An SQL injection is a type of injection attack’s where an attacker can interact with the backend database by using SQL commands ( SQL is a language widely used by applications to interact with the database. It stands for “Structured Query Language”). It arises when an application is not handling user input in the proper attacker and exploits this by giving malicious SQL commands from the input field.

7. Define Brute Force Attack.

Brute Force is an attack used by attackers to try every combination like they use this to find valid login creds of any website. There are two types of brute force attacks – 1) Dictionary attack and 2) Pure brute force attack.

8. Another kind of hacker exists, too?

Apart from White, black, and gray hat hackers, there are some other hackers –

1. Script Kiddies

2. Green hat hackers

3. Blue hat hackers

4. Red hat hackers

5. Malicious insider hacker

6. Hacktivist

7. Elite hackers

8. Gaming hacker

9. Scale hacker

9. Which types of hacking are there?

The first to evolve was computer hacking or system hacking. Today, it is still happening. We started to see hacks like email hacking, website hacking, and network hacking as we moved towards a more digital world. Hackers trying to infiltrate the network try to steal some sensitive data from the website, while hackers attacking the server try to gain access to the webserver.

10. Why is Cross-Site Scripting a problem?

Cross-site scripting is an attack where a malicious user can input malicious javascript codes which will then executes on the client-side by exploiting this an attacker can get sensitive data from the users like cookies, saved passwords, etc.

11. Define phishing attacks.

It is a widely used attack by hackers, in this attack an attacker can construct a fake page like a Facebook login page which looks the same as the original after creating a page they send that page to the victim by email or any other communication media, they use some juicy word phrases i.e. you have received a friend request from a girl or something like that, after reading the email if the user clicked on that link and login with their login creds, their login creds will send to attacker. This is called a phishing attack. 

12. Define social engineering. 

Social engineering is a technique that exploits human error to obtain personal information. It is also called human hacking. By employing social engineering techniques, hackers can obtain sensitive and personal information from their victims.

13. What is the ethical hacker's workflow? 

In the process of hacking, five stages are involved. These include:

Reconnaissance: This is the first step in hacking, we try to gather information as much as possible about the target.

Scanning: In this step, we scan the target to find open ports, running services, and vulnerabilities in that system.

Obtaining access: In this step, we try to exploit the vulnerabilities that we found in step 2 and get access to the system.

Keeping access open: After getting access to the system we install backdoor’s to maintain our access.

Getting track clear: In the last step we clear all the tracks that we used to get into the system.

14. Define reconnaissance.

The goal here is to gather all the information about the system so we can understand it better. You can discover open ports and access points as well as determine network range. 

15. What are the two types of reconnaissance?

The active type is where the hacker is permitted to interact with the system and the passive type is where the hacker has no connection to the system.

16. Getting access is an ethical hacker's goal, but how does one do that? 

The ethical hacker implements the tools and techniques that he learned in the reconnaissance and scanning phase. At this stage, he can gain unauthorized access, and this is called gaining access.

17. How do hackers keep access open?

To maintain the access, hackers use a backdoor, a backdoor is a malware that works on TCP/IP protocol, it sends a connection request to their admin and after a successful connection, an attacker can have full access to the target system.

18. How important is the clearing of tracks?

Hackers should avoid leaving a trail behind them. So no one can trace him how they entered into the system. To do this, you should delete past emails, server logs, uninstall apps, and more.

19. Define scanning.

In this step, we scan the target to find open ports, running services, and vulnerabilities in that system. There are three types of scanning – network scanning, port scanning, and vulnerability scanning.

20. Define virus.

A virus is a type of malware that is designed to spread from device to device, it can harm the computer file systems. It is not self replicated

21. Define worm.

A worm is the same as a virus, however, it can self replicated

22. A worm differs from a virus in what way?

Viruses and worms differ in primarily the fact that the former requires a functioning host program.

23. Define Trojan.

It is malicious software that looks legitimate but can take control of your computer system. It can be bound with any legitimate software.

24. Define trojan-backdoor.

Trojan backdoors are malicious software programs designed to grant unwanted access to the target system. Once a trojan gains a foothold in a system it will automatically add itself to the computer startup routine so that rebooting the computer will not permanently end the malicious process.

25. Define Trojan-Ransom.

Trojan programs such as this modify and encrypt sensitive files. To decrypt or unlock the data, a ransom is required. It is a form of malware that captures some important information about a computer system or a computer network.

26. Define Trojan-Droppers.

Hackers use it to attack systems and drop malware into them. Most antivirus software cannot detect droppers. Trojan-Dropper is a program that is designed to secretly install malicious files and programs to the victim's system without getting noticed.

27. Define Trojan-IM.

An automated program that targets instant messaging applications such as Skype to access the login credentials. It steals your logins and passwords on IM platforms.

28. Define Rootkits.

Unauthorized access to a computer system is made possible through a set of software tools called rootkits. It is a type of malware designed to give hackers access to and control over the target device.

29. Define Trojan-DDoS.

A Trojan-DDoS is a particular malware that negatively affects web addresses. and it's designed to conduct a Dos attack from an infected computer on a pre-defined address.

30. How is hashing done?

This is achieved by generating a string of text using a complex mathematical function. To keep the data accurate, the string of text is used. In hashing large keys are converted into small keys by using hash functions.

31. Define encryption.

Encryption is the process of using an algorithm to transform plain text into cipher text to ensure that sensitive data remains unreadable to unauthorized users. An encoded message can only be read by those who have the key.

32. What are the differences between hashing and encryption? 

Encryption is a two-way process, so it differs from a one-way process that is hashing. Encryption is Reversible but hashing Irreversible. Encryption has variable length but hashing has fixed length.

33. Define exploitation. 

A hacker can exploit a program or script to take over a system. It's designed to find and take advantage of a security flaw or vulnerability in an application or computer system, typically for malicious purposes such as installing malware.

34. How is exploitation done?

To identify vulnerable areas, vulnerability scanners are used.

35. Define enumeration.

Enumeration is defined as a process that establishes an active connection to the target host to discover potential attack vectors in the system, and the same can be used for further exploitation of the system.

It is known as enumeration to get a list of users or networks.

36. How is enumeration done?

It is done by gathering:

1. Names of users and groups and machines

2. Shared network resources

3. Programs installed

4. SNMP 

5. DNS

The Following Cover Advanced-Level Questions And Answers Of Ethical Hacking:

37. Define defacement.

Defacement is a form of vandalism, in which a website is marked by hackers or crackers. Website Defacement is an attack on a website that changes the visual appearance of the site or a webpage. An attack on a web page using SQL injection.

38. How does defacement do?

A website may appear to have defaced data after the query has been executed. Hackers deface a website by gaining unauthorized access to any environment.

39. Define footprinting.

It means gathering information about a target, Get as much information about a target as possible through the attack. It's divided basically into two types-- 

1. Active footprinting.

2. Passive footprinting. 

40. What does footprinting collect?

Most commonly, IP addresses, VPN, URLs, email ids, passwords, and server configurations are collected.

41. How is footprinting classified?

Footprinting data is gathered through both active and passive methods. The methods for connecting to the target system differ. 

Source-- Social Media. Websites. Google. Social Engineering.

42. Define fingerprinting.

Attackers need to identify the kinds of operating systems that they need to penetrate before deploying malware or malicious software.

43. What are other elements of fingerprinting?

TTL

DF

TOS

Window Size

44. Define active fingerprinting.

Active fingerprinting is defined as the process of actively interacting with the target entity, either by using social means, such as calling or emailing. or technical means, such as scanning. The target machine receives specially crafted packets as part of active fingerprinting.

45. Define passive fingerprinting.

This style of fingerprinting does not stiffer traces are sent by a remote system to the one under attack. but relies on sniffing techniques to analyze the information sent in normal network traffic.

46. Define sniffing.

Information passing through a network is monitored in this way. In this way, hackers capture sensitive data. It's divided basically into two types-- 

1. Active sniffing.

2. Passive sniffing.
