What is a hacker and what does it do?

 To break the image of a hacker doing illegal work in front of your computer once and for all, you need to understand what a hacker is and what he does. The hacker is a person specialized in dealing with the structure of software and hardware, which are programs and the physical part of the computer, respectively.


With this knowledge, the hacker's primary role is to ascertain whether systems are secure and to ensure that potential attackers do not have access to information and data that undermine the security of businesses, governments and people.


In order not to be related to criminal activities, they are also known as “good hackers” or “ethical hackers”. Those who commit cyber crimes and use their skills in illegal activities may be known as "crackers".

How to become a hacker?

To become a hacker, you need a lot of knowledge and expertise with computers and the information systems that make it all work.


For that, there are several courses at colleges that prepare students who have an affinity with computers to work in this and in the various fields and have a higher education diploma. Check the list of popular courses in this area:


Analysis and systems development

Computer science

Cyber ​​Defense

computer engineering

Software Engineering

Information Technology Management

Computer network

Information security

Information systems

Systems for internet

They are courses focused on the knowledge of the various structures that are part of the networks and can prepare students so that they know the tools that prevent attacks by crackers.


These degrees are of two types: bachelor's degrees and technologist courses, each with its own characteristics. The bachelor's courses last between four and five years. Technologists, on the other hand, have courses that vary between two and three years, being more focused on all practical aspects and quick entry into the job market.


As these are practically entire courses focused on the computer, technology graduations tend to be very popular in the distance learning (EAD) modality, in addition to being highly sought after in face-to-face and hybrid (semi-face) education.
