computer network with several requests to flood the network and render it
unusable.

it, which would then be sent to hackers.

Hackers
& Hacking Culture

Hackers are people with
advanced technological know-how that performs the exploitation of computer
systems. He/she performs the ‘hacking’. Hackers are usually antisocial and make
up for their communication barrier by hacking.

Hacker culture is mainly
driven by curiosity. Hackers are curious of the vulnerabilities that a new
computer system or network brings, and it gives them fame and reputation
whenever they are the first person to determine and/or exploit a vulnerability

There are two main types of
hackers:

·        
Black
Hat –
Black hat hackers are the people who are mostly portrayed in mainstream media
as ‘hackers’. These hackers have ill-intentions and they violate security for
their own gain. Black hat hackers are exceptionally skilled in computers, but
they use their skills unethically. Most, if not all black hat hacker methods
are against the law.

Some common things black hat hackers do: denial of service attacks, ransomware,
identity theft, keylogging, vandalism, theft

 

·        
White
Hat –
also known as ‘security hackers’ or ‘ethical hackers’, white hat hackers use
their skills to breach and exploit computer systems & networks for the
purpose of reporting these breaches and exploits to the organization
responsible for the systems and networks so that the organization can improve
their security.

A number of organizations
provide bounties to white hat hackers to give them incentive to purposefully crack
their systems so that they can ‘patch’ them afterwards.

·        
Grey
Hat –
Grey hat hackers are those who fall in-between the two types. Grey hat hackers
somewhat do the same thing as white hat hackers, but in the process of hacking
a system/network, they may commit crimes while doing so. Grey hat hackers may
also, instead of privately disclosing the vulnerability to the organization,
may publicly disclose the vulnerability. The main difference between black hat
hackers and grey hat hackers is that grey hat hackers will not use the
vulnerability for their own benefit.
