What is Ethical Hacking and what is it used for?
Ethical hacking is the process of finding vulnerabilities in a system or application, and then informing the appropriate parties how to fix them. Ethical hackers are also called “penetration testers” or “white hat hackers”. These hackers use their skills to find vulnerabilities in order to improve security.
They try to find ways into a computer system, but they don’t do anything that will cause harm. They are usually employed by large companies or organizations to test their systems and networks for any vulnerabilities that could be exploited.
“Hacking” was originally a word used to describe the process of exploiting computer vulnerabilities and it is still used as such today, but “hacker” has also come to be associated with an individual who derives pleasure from discovering and exploring the murky depths of these vulnerabilities. The term “ethical hacking” has emerged to describe the process of identifying and fixing those same vulnerabilities before any malicious hacker can find them.
The Value of an Ethical Hacker; How To Get Started As An Ethical Hacker
An ethical hacker is someone who identifies potential security vulnerabilities in a network, system, or application. They do this to help the company improve their security and protect their customers.
There are many different ways to get started as an ethical hacker. Some people start by taking online courses and certifications like the Certified Ethical Hacker (CEH). Others just learn on the job from experience, or even from hacking into their own networks to find vulnerabilities and fix them.
If you’re looking to get a job as an ethical hacker, then the first step is to figure out what type of ethical hacker you want to be. If you want a more traditional career with large companies or government, then getting a Masters in Information Security could be a better fit.

What are the types of ethical hackers?
They are the ones who find vulnerabilities in a system and then report them to the company. They help companies to make their systems more secure and safe for the users.
One of the most important types of ethical hackers is a penetration tester. These people test company’s security system by doing things like scanning, probing, or trying to break into it. Penetration testers can work for companies or be hired by other companies that want to know how secure their system is before they launch it for public use.
Another type of ethical hacker is a vulnerability researcher. These people find vulnerabilities in software, hardware, or anything that can be hacked and then report them so that they can be fixed before something bad happens like someone using them to do something malicious or dangerous.
The Difference Between Black Hat And White Hat Hackers
A black hat hacker is someone who hacks into a system with malicious intent. They want to steal information, destroy data, or disrupt the system.
A white hat hacker is someone who hacks into a system with good intent. They want to find vulnerabilities and fix them before they are exploited by the black hats.
Black hats have malicious intentions, while white hats have good intentions.
Some examples of black hat hackers are:
- Thieves: They steal things such as money and items.
- Spies: They gather information without the consent of the owner.
- Hackers: They seek to disrupt or destroy systems with malicious intent.
Some examples of white hat hackers are:
- Computer programmers and IT professionals that find vulnerabilities and fix them before they are exploited by the black hats.
- Security researchers who find vulnerabilities and help companies patch them before they are exploited by the black hats
- White hat hackers may also have their own business, such as penetration testing companies
What are the various types of Ethical Hacking?
Ethical hacking is a term that has been around for quite some time now. The term ethical hacking was coined by Loyd Blankenship in the late 1980s.
There are various types of ethical hacking that include system penetration testing, application security testing, social engineering, physical security and many more.
System penetration testing:
System penetration testing is the process of trying to penetrate the system’s defenses without authorization or the consent of the owner. The goal of this type of test is to see if it can be done and how easy it would be for someone else to do so.
Application security testing:
Application security testing is performed on applications with a specific focus on finding bugs or vulnerabilities that may allow an attacker unauthorized access into an application or network.
Social engineering is a form of attack where one attempts to gain information from people through deception , and also manipulate them to get what one wants. In this example, the attacker is posing as a network admin that needs you to approve some changes on your computer.
The following list includes some of the most common tools used by Ethical hackers.
There are many tools that can be used by ethical hackers. The most common ones are:
- OWASP ZAP
- Burp Suite Pro
Ethical Hacking and the Importance of Looking After Your Computer’s Security
It is essential that we take care of our computers and the data contained therein. Hacking is a major concern for most people, but it does not have to be.
The first step in ensuring your computer’s security is to make sure that you have a strong password (one that has numbers, letters, and symbols). The second thing you should do is install anti-virus software on your computer so that it can scan the internet for viruses before they get onto your system.
There are also other precautions you can take to ensure the safety of your computer and its data. For example, you should never open attachments from unknown sources or click on links from suspicious emails.
You should also keep all of your software up-to-date to prevent any security vulnerabilities from being exploited by hackers. Lastly, it is important to be careful about what information you share on social media since this could be used by hackers as well as identity thieves.
Stop hackers before they have a chance to attack you by following these steps:
- You should always use a firewall, antivirus and backup system for your website.
- Make sure you know who is managing the hosting server for your site.
- Keep an eye on what other sites are linking to yours, as this can be an indication of where the vulnerability might be coming from.
- Make sure you don’t have any custom software added to your website that could be exploited.
- Be careful of the software you are using and who it is from.
- Make sure all the content on your website is appropriate, including word choice and clarity.
- Finally, make sure all the URLs on your site are unique and that they can’t be guessed or found in a Google search.
What is DOS (Denial of service) attack?
Denial of service (DOS) attack is a form of cyber-attack. It is an attempt to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet.
There are many forms of DOS attacks, including:
This is one of the most common methods used in DOS attacks. In this type, the attacker sends large numbers of SYN packets to a target machine with the intent that the machine will not be able to handle all these requests and will crash. This attack can be prevented by implementing SYN cookies and SYN rate limiting on servers.
Teardrop attack exploits flaws in TCP/IP protocol implementation and causes fragmented packets to overlap each other and cause packet loss. The attacker sends multiple overlapping IP fragments with different destination ports, which causes fragmentation and packet reassembly at the destination host causing it to crash or become unresponsive.
This type of attack sends huge number of pings to a target machine causing it to become unresponsive. This can be prevented by implementing rate limiting on servers.
Ethical hacking Frequently Asked Questions
What is the Meaning of IP address and a MAC address?
An IP address is a number that identifies a computer or device on the internet. It is used to locate and identify the computer so that data can be sent to it.
A Mac address is a unique identifier for a network interface card (NIC) which helps devices in a network find each other.
What is SQL injection?
SQL injection is a type of attack that exploits the security vulnerability of an application that uses SQL queries to construct and execute commands.
SQL injection is a type of attack in which the attacker sends specially-crafted SQL statements to the database server, which then executes them as actions within the application.
What is footprinting in ethical hacking?
Footprinting is the process of gathering information about a target computer system. The information gathered can be used to identify vulnerabilities and other weaknesses in the system. It is often done for the purpose of hacking.
Footprinting is a process of obtaining as much information about an organization or individual as possible, in order to create a profile that can be exploited later on.
Footprinting techniques include: reconnaissance, scanning, enumeration, and vulnerability assessment.
What is Network Sniffing?
Network sniffing is a technique used to capture packets of data as they traverse a network. It’s an important tool for network administrators that helps them troubleshoot and monitor networks. Network sniffers are software programs or hardware devices that monitor all traffic on the network and make it available for analysis.
This includes not only the content of the traffic, but also its timing and other properties such as packet length and frequency. The term “network sniffer” can refer to either software or hardware, but in this article we’ll use it to refer exclusively to software programs.
What is ARP Spoofing or ARP poisoning?
ARP spoofing or ARP poisoning is a technique in which an attacker sends out an ARP (address resolution protocol) request with their own MAC address as the target’s. This confuses the switch into thinking that the attacker’s computer is actually on that network and all traffic for that computer will be sent to them.
This confuses the switch into thinking that the attacker’s computer is actually on that network and all traffic for that computer will be sent to them.
An attacker can achieve this by using a tool called “Netcat” which is installed on their computer. It makes it easier for Netcat to listen for traffic for the target computer and route it to them.
What is Mac Flooding?
Mac Flooding is a technique that is used to get a user to download and install malware or phishing software. This technique can be carried out by sending large amount of messages, emails or tweets with the same file name and content.
The aim of this technique is to fill up the user’s inbox so that they are unable to find the real message among all the spam messages. This type of attack can also be carried out by sending a single email with multiple attachments.
What is Keylogger Trojan?
Keyloggers are typically installed on a computer through phishing or drive-by downloads. They can also be downloaded by users themselves unknowingly, if they are not paying attention to what they download.
The keylogger saves all the data it collects in some hidden folder and sends the information back to its creator via email, FTP or other networking protocols.
What is Pharming and Defacement?
Pharming is a technique of hacking web sites to redirect visitors to another site. This can be done by entering the URL of a legitimate site into an address bar, and the user will be redirected to a fake website that looks like the original one.
Defacement is a type of computer sabotage in which someone alters or replaces data on a website without permission.
Pharming and Defacement are two types of cyber attacks that are on the rise. These cyber attacks are often used for malicious purposes such as stealing information from users and disrupting business operations.
