So, what does it take to become the dark knight of technology?
Yes, we are talking about Ethical Hacking.
You have probably dreamt of being an ethical hacker from the time you started coding. Or, maybe it was the time when you have hacked through your school’s wifi password so that you can finish your project in time. Maybe it was at that point when you hacked your boyfriend or girlfriend’s social media account just o spy on them. There have been different times for each of you when you realized that you have grown fond of hacking, and at a certain point of time, you have decided to take up hacking as a career for good and becoming an ethical hacker. But now the million-dollar question arrives. Do you have what it takes to become an ethical hacker?
In our previous blog “Certified Ethical Hacker: The Dark Knight Of Technology”, we have mentioned all the skills that you’d need to acquire to become an ethical hacker. Let us state them in nutshell once again. In order to become an ethical hacker, you’ll have to have:
Think you have it all?
Now let’s walk you through the 20 most important Ethical Hacking interview questions with answers!
Ans. Ethical hacking is an act of locating the weaknesses and vulnerabilities of computer and information systems by duplicating the intent and actions of malicious hackers. Ethical hacking is also known as penetration testing, intrusion testing, or red teaming. An ethical hacker is a security professional who applies their hacking skills for defensive purposes on behalf of the owners of information systems.
Ans. ARP Poisoning is a technique by which an attacker sends spoofed Address Resolution Protocol (ARP) messages onto a local area network. Generally, the aim is to associate the attacker's MAC address with the IP address of another host, such as the default gateway, causing any traffic meant for that IP address to be sent to the attacker instead. It is also known as ARP spoofing or ARP cache poisoning.
Ans. Here are a few ways to avoid ARP poisoning:
Ans. Footprinting is gathering information about a target system that can be used to execute a successful cyber attack. To get this information, a hacker might use various methods with variant tools. This information is the first key for the hacker to crack a system.
Ans. Some widely used footprinting techniques are:
Ans. IP address is an address that is assigned to every device so that it can be located on the network.
On the other hand, Mac address is a unique serial number that is assigned to every network interface on every device.
Ans. Some common Ethical Hacking tools are as follows:
Ans. There are 4 types of Ethical Hackers:
Ans. DOS or a denial-of-service attack (DoS attack) is a cyber-attack in which the perpetrator seeks 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. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled.
Ans. The regular types of DOS assaults are:
Ans. Pharming is a strategy where the attacker compromises the DNS (Domain Name System) servers or on the user PC with the goal that traffic is directed towards the malicious site.
During the defacement strategy, the attacker replaces the firm’s site with an alternate page that contains the hacker’s name, images and may even include messages and background music.
Ans. SQL is a technique to steal data from organizations. It is executed by creating a fault in the application code. An SQL injection happens when you inject the content into a SQL query string and the result mode content into a SQL query string. After that, the result modifies the syntax of your query in ways you did not intend.
Ans. Some social engineering attacks are as follows:
Ans. Phishing technique is executed by sending false e-mails, chats or websites to impersonate real systems with the goal of stealing information from the original website.
Ans. CowPAtty is a C-based tool for running a brute-force dictionary attack against WPA-PSK and audit pre-shared WPA keys.
Ans. A CIA Triangle involves 3 main components:
Ans. A media access control attack or MAC flooding is a technique employed to compromise the security of network switches. The attack works by forcing legitimate MAC table contents out of the switch and forcing a unicast flooding behavior potentially sending sensitive information to portions of the network where it is not normally intended to go.
Ans. Network sniffing is the use of a software tool, called a network sniffer, that monitors or sniffs the data flowing over computer network links in real-time. This software tool is either a self-contained software program or a hardware device with the appropriate software or firmware.
Ans. The types of password cracking techniques include:
Maybe you are thinking, you just have to study these interview questions and voila! You are a champion who would be able to give the dark side of the web a taste of its own medicine. But that’s not it. If you really want to get hired to be someone who can roll the dice in dark for an organization’s good, that can only be achieved by taking the Ethical Hacking training! So hurry up and check the details of our virtual Certified Ethical Hacker sessions right away!
Apart from having a quirky way of writing, she has a vast knowledge regarding Data Science and Machine Learning. Her blogs are portrayed in a storytelling format that makes the readers understand the complicated technical parts swiftly. She prefers staying up to date about the new happenings of the tech world and pinning them down in articles to make our readers well aware of it and has been doing a pretty great job in that.
