The Internet is one of the main means by which information is distributed in the form of bits and bytes. News, opinions, tutorials and products are spread across the Web at a speed never seen in other media. Precisely for this reason, with so much data available at just one click, information security is more than necessary. After all, spreading information that is confidential, false or that simply shouldn't be published for exposing someone, is a practice that should be avoided and has consequences. But after all, what is Information Security and how does it work?

What is Information Security? The term is used to refer to data protection and the practice that ensures that sensitive information can be accessed only by those to whom it refers (in other words, their legal guardians). Information security is a great ally of companies, as it is responsible for preventing anyone from distributing data about sales, profit margin, competitors, among others, improperly. In a world in which several tasks are performed at the same time and confidential e-mails can be sent in just one click, it is essential that there is protection against any errors. In such cases, Information Security allows the construction of policies and methods that are used in the circulation of confidential data and are controlled by a company's Information Technology (IT) department.

Generally, programs are installed to ensure that computers will be used only for work purposes, in addition, it is essential to ensure that employees have not downloaded any type of program on the computer, since a simple bug or malware can put everything at risk. That is why corporations foresee strict punishments (and even risk of dismissal) for any employee who breaks rules of information use, whether they are in an email with sales reports, spreadsheets referring to the percentage of profits, presentations, models and prototypes and even even passwords and personal files, since once inside the network you can capture the entire data flow. Information Security can also be used by individuals, especially on social networks that practice various scams with false links called “phishing” which consists of recreating a page identical to the original and having the victim insert their login and password data. To ensure your privacy and the security of your data, use a good antivirus, do not log in using your social networks on sites you do not know, always check in the email header if it corresponds to the sender and use passwords that are difficult to guess containing letters, numbers and special characters such as “@! * #” avoid sharing them with others, All of this is part of the basic properties of Information Security, which are: confidentiality, availability, authenticity, integrity and legality.

How do I protect my personal data? Avoid connections on public networks like cafes, bus stations and airports as they have free connection without any type of authentication “for an attacker it is like locking the door and leaving the window open” Be wary of promotions and offers from stores that are too attractive, especially at the time of payment as the only payment option is via boleto. E-mails from banks or stores always check the e-mail header, large companies use their own domains, so they will never use Gmail, Hotmail, bol and etc.

Because of the importance of the area for the protection of confidential data, there are postgraduate courses, MBA courses and also courses that do not require previous graduation and can be found on platforms such as Udemy.
