Ethical Hacking Practice Test Questions
and Correct Answers
White Hat Hacking ✅The term "white hat" in Internet slang refers to an ethical
computer hacker, or a computer security expert, who specializes in penetration testing
and in other testing methodologies to ensure the security of an organization's
information systems.[1] Ethical hacking is a term coined by IBM meant to imply a
broader category than just penetration testing.[2] White-hat hackers may also work in
teams called "sneakers",[3] red teams, or tiger teams.[4]
Grey Hat Hacking ✅The term "grey hat" or "gray hat" refers to a computer hacker or
computer security expert who may sometimes violate laws or typical ethical standards,
but does not have the malicious intent typical of a black hat hacker.
The term began to be used in the late 1990s, derived from the concepts of "white hat"
and "black hat" hackers.[1] When a white hat hacker discovers a vulnerability, they will
exploit it only with permission and not divulge its existence until it has been fixed,
whereas the black hat will illegally exploit it and/or tell others how to do so. The grey hat
will neither illegally exploit it, nor tell others how to do so.[2]
Black Hat Hacking ✅A black hat hacker is a hacker who "violates computer security for
little reason beyond maliciousness or for personal gain."[1]
The term was coined by Richard Stallman, to contrast the maliciousness of a criminal
hacker versus the spirit of playfulness and exploration of hacker culture, or the ethos of
the white hat hacker who performs hackerly duties to identify places to repair.[2] It is a
reference to the black and white hat symbolism in film.
Black hat hackers form the stereotypical, illegal hacking groups often portrayed in
popular culture, and are "the epitome of all that the public fears in a computer
criminal".[3] Black hat hackers break into secure networks to destroy, modify, or steal
data; or to make the network unusable for those who are authorized to use the network.
DoS ✅In computing, a denial-of-service (DoS) attack is an attempt to make a machine
or network resource unavailable to its intended users, such as to temporarily or
indefinitely interrupt or suspend services of a host connected to the Internet. A
distributed denial-of-service (DDoS) is where the attack source is more than one, often
thousands of, unique IP addresses. It is analogous to a group of people crowding the
entry door or gate to a shop or business, and not letting legitimate parties enter into the
shop or business, disrupting normal operations.
Criminal perpetrators of DoS attacks often target sites or services hosted on high-profile
web servers such as banks, credit card payment gateways; but motives of revenge,
blackmail[1][2] or activism[3] can be behind other attacks.
