Ethical Hacking Interview Questions

If you’ve got hacking skills, you can turn your ethical hacking into a career. Ethical hacking is the term given to penetration testing and prevention. Your career is based on your hacking skills, but you use them to protect companies against malicious hackers. Before you decide to interview, here are some questions you might run into when interviewing for a job.

1. What is an IP address?

A: An IP address is a virtual number assigned to a computer. It’s the address used by the TCP/IP protocol to identify a machine on the network. A computer must have a unique IP address or a conflicting IP error will occur.

A: The MAC address is the physical address of the computer. This address is also unique, and it is tied to the IP address when the IP is assigned to your computer. MAC and IP addresses work together to identify a computer on the network. The main difference is the MAC address is physical but the IP address is virtual.

A: Footprints leave a trail for ethical hackers to investigate. A footprint can be a physical file or social media footprints. A user can leave a footprint from domain registrations.

A: A brute force hack tries to “guess” a password and user name using a dictionary. A brute force attack takes longer but it uses each value in the dictionary attack.

A: A denial of service attack sends massive amounts of traffic to a website in an attempt to crash either the router or the web server. Hackers can use a syn attack, buffer overflow attack, smurf attack or even viruses.

A: SQL injection is a type of hack that sends SQL commands to a server. The SQL injection attack runs commands on the server and either inserts data or returns data to the attacker.

A: there are phishing attacks that trick people into entering data by using a website or form that looks similar to a bank website. Baiting is also a type of attack that tricks people into entering information on a malicious website.

A: Network sniffing reads the data packets sent over a network between a user and the web server. Network sniffing can be combated using SSL or encryption when communication with a web server.

A: A rogue DHCP server can redirect IP address assignments to allow the hacker to identify and redirect the client computer to another network segment. The hacker can then sniff network traffic from the target machine.

A: WireShark is a software penetration testing tool that lets you sniff network traffic and identify rogue packets for testing and security purposes.
