World Internet Day: security is a challenge for users

 The anguish we feel when we forget the cell phone and run out of communication or the bad feeling we have when we realize that the internet has "fallen" are some of the symptoms of a time when we are increasingly connected to the world wide web. However, it is necessary to be careful and learn to use the resources that multiply and promise to make life easier for users. On World Internet Day, celebrated on May 17, professors at the Paula Souza Center (CPS) discuss access to the web in Brazil, navigation security issues and what can be expected of a future that promises to be increasingly digital.


The numbers that show Brazilians' access to the internet are significant, although there is still a large margin for growth in this audience. According to the Brazilian Institute of Geography and Statistics (IBGE), in 2016, 116 million people were connected to the web, equivalent to about 65% of the national population. Google released a survey in 2017 revealing that 86% of Brazilians watch videos on the web and 99% search for content on YouTube.


With so many accesses, improving security on the internet becomes a relevant issue. “It is necessary to increase the levels of cryptography”, defends the professor at the State Technology Faculty (Fatec) Carapicuíba Magali Andreia Rossi. Through this procedure, a message transmitted over the internet is encoded so that only the sender and the receiver have access to its content. This is the case, for example, with the transmission of information via WhatsApp. Magali explains that banks have strict control systems, but many online stores only have digital certificates, which does not give many guarantees to customers.


The teacher gives tips to navigate more safely. "It is important to have an antivirus capable of detecting the most common types and always checking the website's URL," he says. She explains that scams that involve a page very similar to that of a bank or store are common. "The visual part is the same, but the website address is not exactly the same." Finally, Magali suggests covering the notebooks' camera with masking tape, to avoid having their images recorded by some software.


Suspicious email


Professor João Carlos Lopes Fernandes, from Fatec São Caetano do Sul, recalls that no company requests data or registration updates by email. “Call the bank and check if the email is real. Don't go straight by clicking on the link ”, he warns. He also suggests keeping your computer up to date and running a good antivirus.


For Fernandes, another challenge for the internet in Brazil is improving access, the coverage area. "Complaints about the fact that you hire a plan are very common, but you don't get what you're paying for."

In Magali Rossi's opinion, the future will have much more interaction with network users, through resources such as holography, augmented reality and virtual reality. With augmented reality, it is possible for a device, such as a cell phone, to bring elements to the real world, as in the Pokémon Go game. In virtual reality, a kind of glasses transports the user to a digital environment. "Today we receive information passively, but that tends to change."


According to Fernandes, more and more services will be available on the internet. “Today we call a taxi, check the bus schedule, register at Zona Azul, all by cell phone,” he recalls. "The internet will become more and more part of our life." The trend is for cars, buildings and appliances to be connected to the web, what is known as the internet of things.


Programming


It is with an eye on that future that the Curriculum Formulation and Analysis Group (Gfac) of the State Technical Schools (Etecs) is working. Hugo Ribeiro de Oliveira, one of those responsible for the technological axis of Information and Communication at Gfac, explains that the trend is that all professionals have to learn to program or, at least, learn to communicate with a programmer to work together.


With that in mind, Gfac begins to develop curriculum components for courses that are not directly linked to the IT area. The idea is that all high school and technical students have the knowledge to work in an increasingly digital world.

What is a DDoS Attack? A Simple Definition

Since we’re all about making technical topics simple, let’s start with a basic answer to the question: What does DDoS mean (a.k.a. “What is a distributed denial of service attack”)? As mentioned above, a DDoS attack is a bit like a traffic jam on a website (but it’s intentionally caused by a hacker). Here’s a simple definition for the meaning of DDoS: A DDoS (distributed-denial-of-service) attack is when a hacker makes a website or other service inaccessible by flooding it with requests from many different devices. If you’ve also heard the term “DoS attack,” don’t let that confuse you. A DDoS attack is just a specific type of DoS (denial-of-service) attack — one that uses multiple computers/devices to attack with. How Does a DDoS Attack Work ? Just like a traffic jam floods a highway with more cars than it can handle, a DDoS attack floods a website with more requests (i.e. visitors) than the web server or other related systems can handle. Many hackers use botnets (a.k.a.

How to prevent a DDoS?

Keeping yourself protected from DDoS attacks is something that is often easier said than done because of the fact cybercriminals will often stop at nothing to gain unauthorised access to private data, and many international brands such as Netflix, AirBnB, and Spotify have all become victims in the past. In spite of this, there are certain things that can be done in an effort to prevent a DDoS attack from occurring. Denial of service attack definition Firstly, you will need to make sure that any firewalls and routers are configured in the correct manner and applied with up-to-date security patches. Similarly, it’s also worth regularly checking for security updates for your Internet of Things (IoT) devices and adding a password where possible. This is because these devices have been increasingly targeted by hackers in recent years. Doing everything in your power to keep things up to date will ensure that any bogus traffic is promptly rejected during a process whereby network traff
