Today cybersecurity is an increasingly important issue in technology for large, medium, and small companies, also for the users who consume it. That is why this article will see what cybersecurity is, its importance, how it can be applied and its demanded profile in the labor market, you will see how exciting this topic is in our daily life and how it can help us.
According to security professionals at ISACA (Information Systems Audit and Control Association), cybersecurity is defined as a layer of protection for information files; based on this, work is done to avoid all kinds of threats, which put the information that is processed, transported and stored on any device. You have probably heard this word before. Lately, we hear it everywhere. However, do you know that this term could have been coined more than 80 years ago?
The definition of cybersecurity could be:
“The set of processes used for the management and protection of the transmission, processing, use, and storage of data and information, using information and communication technologies (ICT).”
However, it was not until the advent of computers in the 1970s that the term hacker was first coined.
Tools to increase security
- Protection against malicious code malware: Commonly known as antivirus, this type of security is essential for any organization, regardless of their activity or size, it is also essential to go beyond computer systems, workstations or servers, and gather all aspects related to mobility. A large number of different types of malware and their evolution, become one of the most challenging threats to deal with.
- Anti-fraud or pishing protection: This is one of the most important, common sense. Cheating has become one of the most widely accepted practices on the Internet, both to infect thousands of devices and to get user data. Here there are no tools to combat these threats; you have to have common sense and be suspicious of suspicious places.
- Be proactive These tools consist of achieving by various means the survival of the organization or company, after a security problem, within this solution are backups in the cloud or other devices, which keep the information of the company, which is essential to carry out its functions. There are also other solutions such as systems recovery tools, which allow you to restore a system from one point from before the attack to lose as little data as possible.
- Protection of communications: These solutions are in charge of protecting the organization from a group of threats, such as a denial of service attacks, unauthorized access, or the interception of communications. We must also bear in mind that threats can not only come from the Internet, but also from within companies, which is why the protection of communications is essential when there are several offices or headquarters in various parts of the world when they are carried out daily through the Internet. The above tools are the fundamental basis of the necessary security solutions in any company. We must not forget that these solutions are only part of the security puzzle to be safer from unwanted attacks.
What is a hacker?
There is no doubt that the arrival of new technologies has forever changed the world. Although it enables smoother labor relations, faster processes, and practically eliminates borders; technology can negatively affect organizations, an idea from which concepts such as cybersecurity and the term hacker are born. In many places, we can find the term hacker applied to cybercriminals, to people who, with excellent knowledge of computers, are engaged in illegal activities. Well, this definition does not correspond to the term hacker, but to one of the branches that exist within it. A hacker is simply a person with high computer skills; Hackers currently master mainly programming languages, software and hardware manipulation, and telecommunications.
Why do we call hackers?
Within the hacker world, there are two distinct groups:
- The White Hat Hackers
- The Black Hat Hackers
Usually, we apply the term hacker to the second group, but the first one is also within this broad concept. In fact, in addition to these two very different groups, we find two more groups that also have an increasing impact: gray hat hackers and crackers.
White hat hacker
These are what are commonly called “ethical hackers. ” These are people who, as we said before, have extensive knowledge of programming, software, hardware, and telecommunications and use it to protect the transfer of data in organizations.
Primarily, the White Hat is dedicated to cybersecurity, a professional market that is growing more and more and whose salaries are skyrocketing due to the lack of experts.
Gray hat hacker
This group is always controversial to categorize because we could say that they are Black Hats that become White Hats. In this group, we find hackers who violate the security systems of large organizations and then ask them to hire them. That is, they use illicit means to demonstrate their knowledge and get to work in cybersecurity. Also, on many occasions hackers of the type of those who form the group Anonymous are brought into this group; They are dedicated to delivering justice (uncovering political and economic fraud, unmasking consumers and providers of child pornography), but by using methods that violate data protection rights, they usually fall into this group.
Black hat hacker
This group is made up of all those that we commonly mid-call hackers. Perfect connoisseurs of the computing environment, they are dedicated to generating especially viruses, spyware, and malware, and making money from it (mainly through extortion).
Also located within the Black Hat group, the main objective of crackers is to decrypt software and offer paid products for free.
What phases does it consist of?
For a few years, the word cybersecurity has become a standard among companies since computing is already a common tool in business, and to keep systems safe, they lack security measures to help us avoid being exposed to significant risks. When we consider what cybersecurity is, it must be said that it is known as information technology security, since it encompasses a large number of techniques and methods to protect our system. Thanks to the tools we have available about cybersecurity, our system will be better protected from computer attacks, hacks, or any theft of data or identity.
What are the most common threats?
Even though computer attacks are the order of the day and are continually being renewed, we can say that several threats are prevalent and familiar within this sector. We are referring to cyberwarfare, cyberterrorism, and cybercrime. What does each of these threats consist of?
Cyberwar: This is an attack whose purpose is generally political. In this context, cybercriminals try to collect as much information as possible and relevant data that may compromise a political party or government in the future. There have been notable cases of political parties whose structure has been shaken due to one of these actions.
Cyberterrorism: It is another form of a common threat, but this time, although it is also trying to collect the maximum amount of information, the purpose is different, since the objective is to create an environment of terror among citizens. One of the great fears of today’s society is losing stability due to it.
Cybercrime: Cybercrime is one of the most common threats and the one that most often occurs in all types of countries. Through it, hackers access protected computer systems and try to make financial profits. It is also done at the user level, taking control of specific devices and requesting economic amounts in exchange for their release, among other possibilities.
