Information Security: what it is and why it is so important

Since the popularization of the internet, the information security is vital to protect Dice and sensitive information circulating throughout the online network. Thanks to it, we can make online purchases, bank transactions, and a series of activities safely, using just the PC or smartphone.

However, just as technology evolves every day to protect this data, on the other hand, there are cyber criminals who live by exploiting holes in software and operating systems to commit crimes like ransomware. With that, there is a daily battle in which security becomes more and more fundamental in the online network.

Today, TecMundo explains the topic better, in addition to showing how you can pursue a career in one of the most important areas of the market. Check out:

What is Information Security

As its name suggests, information security is responsible for protecting sensitive data and information about people and companies on the internet. It is with it that rules, mechanisms, and methodologies are created that aim to secure data traffic between, for example, a company and a customer, or a software and a user.

Every large company has an area dedicated to data security in its Information Technology (IT) sector. It is she who creates protocols to prevent from unauthorized access to sensitive information, to the internal blocking of websites and applications so that their employees do not compromise the corporate network.

The sector is also one of the ones that live in constant evolution. Every day, new technologies are created and implemented in order to give more security to operations such as online purchases and financial transactions. Since criminals live by exploiting loopholes to carry out a series of cyber crimes, from stealing sensitive information, such as personal and banking data, and even total and remote control of a computer.

To complete, today it is also necessary to deal with a crime that is becoming more and more frequent, and that has already affected large companies and institutions: ransomware. It consists of the sequestration of information from an establishment’s database, demanding a value for the release, which is paid in cryptocurrencies, precisely to make it difficult to track whoever committed the crime.

In Brazil, ransomware was the most common criminal attack on companies in 2021. And this type of crime does not only happen in the country. In Cuba, for example, a gang of cybercriminals managed to extort more than R$ 250 million with attacks on the financial sector , healthcare, manufacturing and IT.

The importance of Information Security in everyday life

Although the concept may seem like something more linked to companies and organizations, Information Security is also needed by the user. In other words, as much as stores, websites and companies have a strict protocol for protecting your data, you also need to be very careful in how you expose it on a daily basis.

From keeping an up-to-date antivirus on your PC and cellphone, to preventing access to unknown sites without a security certificate, you must be aware of what is passed on daily. So avoid making common mistakes that can make life easier for criminals such as:

  • take photos of documents, credit cards and share in messaging apps or leave them in your mobile gallery;
  • avoid exposing data such as your social security number, phone number, e-mail to strangers (as in pranks to “receive a PIX”);
  • do not install unknown software outside of official stores such as App Store or Play Store.
