1: What is Ethical Hacking?

In the context of computer security, the process of simulating cyberattacks in order to find flaws in a computer system, network, or application is referred to as ethical hacking.  In contrast to harmful hackers, also known as black hat hackers, ethical hackers, also known as white hat hackers, employ the same methods and tools as black hat hackers, but they do so with the permission of the owner and with the intention of enhancing security rather than producing harm.

2: What is the difference between Ethical Hacking and Cybersecurity?

The broader topic of cybersecurity encompasses a variety of activities, one of which is known as ethical hacking. Protecting systems, networks, and data from unauthorized access, use, disclosure, interruption, modification, or destruction is the overall goal of cybersecurity, which comprises all of the techniques and procedures that are employed to achieve this goal.

Ethical hacking is a technique that helps find vulnerabilities in a system’s defenses, which enables specialists in the field of cybersecurity to put suitable precautions into place.

3: What are the advantages and disadvantages of hacking?

The prime advantages and disadvantages of hacking are as follows:

Advantages (Ethical Hacking):

  • Identifies security vulnerabilities,
  • Improves overall system security posture,
  • Helps organizations stay ahead of cyber threats, etc.

Disadvantages (Malicious Hacking):

  • Data breaches and leaks,
  • System disruptions and downtime,
  • Financial losses,
  • Reputational damage, and many more.

4: What are the different types of hackers?

The different types of hackers are as follows:

  • White Hat Hackers (Ethical Hackers),
  • Black Hat Hackers (Malicious Hackers), and
  • Gray Hat Hackers.

5: What can an ethical hacker do?

Ethical hackers can:

  • Identifying vulnerabilities in systems and networks can be accomplished through the use of penetration testing.
  • Examine the policies and procedures pertaining to security.
  • Develop and put into action certain safety precautions.
  • Maintain a current knowledge of the most recent hacking techniques.

6: What is Pharming and Defacement?

  • Pharming: It takes people to a fake website that appears to be real in order to steal their personal information.
  • Defacement: Changes made to the visual look of a website that are malicious in nature.

7: Distinguish between phishing and spoofing?

  • Phishing: This malware sends users misleading emails or messages in an attempt to fool them into divulging personal information or clicking on dangerous links.
  • Spoofing: For the purpose of deceiving users, involves impersonating a reliable source (such as an email address, website, or phone number).

8: What is network security, and what are its types?

Network security allows for the protection of networks and devices against unwanted access, hence guaranteeing the availability, integrity, and confidentiality of data. There is a variety of network security, including the following:

  • Perimeter security,
  • Wireless security,
  • Endpoint security,
  • Data security, etc.

9: What are network protocols, and why are they necessary?

Rules that are standardized and regulate how devices communicate with one another via a network are referred to as network protocols. In addition, they guarantee compatibility and facilitate the sharing of data. Protocols such as TCP/IP, which stands for Transmission Control Protocol/Internet Protocol, are essential to the functioning of the Internet.

10: What do you understand by footprinting in ethical hacking? What are the techniques utilized for footprinting?

The first step in the process of ethical hacking is called “footprinting,” and it involves gathering information about a target system or network during this stage. Different methods include:

  • DNS interrogation,
  • Social media reconnaissance,
  • Searching public databases, etc.

11: What are the hacking stages? Explain each stage

Hacking is often a multi-step process that includes the following stages:

  • Reconnaissance,
  • Scanning,
  • Gaining Access,
  • Maintaining Access,
  • Covering Tracks, etc.

12: What is scanning and what are some examples of the types of scanning used?

Utilizing various technologies to locate vulnerabilities within a system or network is what is meant by the term “scanning.” Various kinds of scans include the following:

  • Port scanning,
  • Vulnerability scanning,
  • Stress testing, etc.

13: What are some of the standard tools used by ethical hackers?

Many tools are used in ethical hacking, including:

  • Kali Linux,
  • Nmap,
  • Nessus,
  • Burp Suite, etc.

14: What is Burp Suite? What tools does it contain?

A tool for evaluating the security of online applications, Burp Suite is available for free and is open-source. Through the use of a wide range of tools, it provides ethical hackers with the ability to locate vulnerabilities in web applications. These are some of the tools that are included in the Burp Suite:

Proxy For the purpose of analysis, intercepts web communication on the way between the browser and the web server.
Scanner In order to identify typical vulnerabilities, web applications are automatically scanned.
Intruder Contributes to the testing of various inputs and the manipulation of requests in order to find vulnerabilities.
Repeater Replaying and changing HTTP requests is possible in order to test the functionality of the system.
Sequencer The behavior of the application is analyzed in order to locate any potential logic problems.

15: What is network sniffing?

The act of recording data packets as they pass over a network is known as network sniffing.  Sniffing tools are used by ethical hackers to examine network traffic and spot possible security risks such as unencrypted data transfer or questionable communication patterns.

16: What is SQL injection and its types?

SQL injection is a vulnerability in web applications that permits malignant SQL code to be injected into the database queries of a website. This may be exploited to modify data, pilfer sensitive information, or even seize control of the database server. Diverse varieties of SQL injection assaults exist, encompassing:

  • In-band SQL injection, and
  • Out-of-band SQL injection.

17: What is cross-site scripting and its different variations?

Cross-site scripting (XSS) is a form of web security vulnerability through which malicious scripts can be injected into a website by an adversary. The execution of these scripts in a user’s browser could result in the theft of sensitive data such as cookies and session identifiers. Diverse iterations of XSS attacks exist:

  • Stored XSS,
  • Reflected XSS, and
  • DOM-based XSS.

18: What is a denial of service (DOS) attack and what are the common forms?

The objective of a denial-of-service (DoS) attack is to render an infrastructure or network inaccessible to authorized users by inundating it with traffic. Frequent DoS assaults consist of:

  • SYN flood,
  • UDP flood,
  • Application-layer DoS, etc.

19: How can you avoid or prevent ARP poisoning?

ARP poisoning is a form of cyberattack in which an assailant manipulates the Media Access Control (MAC) address of another device in order to deceive a network device. Follow these steps to avoid ARP poisoning:

  • Enable static ARP entries,
  • Use strong network authentication,
  • Enable ARP inspection on switches, etc.

20: What is the difference between VA and PT?

The basic differences between Vulnerability Assessment and Penetration Testing are mentioned below:

  • Vulnerability Assessment (VA): An extensive and automated scan that detects potential system or network vulnerabilities. While it offers a broad perspective on security vulnerabilities, it might inadvertently overlook particular defect types or their severity.
  • Penetration Testing (PT): A manual and more comprehensive procedure that simulates actual assaults in order to exploit vulnerabilities and evaluate their consequences. Assisting in the prioritization of remediation efforts, PT offers more comprehensive insights into security risks.
