Learn now what is Cybersecurity and what is the relationship with Industry 4.0

If the internet is the answer to many of our problems, cybersecurity is the question. With the increasing number of digital crimes, the question is: what are the threats to users, businesses and governments?

We are increasingly connected and immersed in the world of technology and, with the increasing use of new products and services, discussions on network security, user data and privacy have intensified.

Companies nowadays operate with a large volume of data, which previously did not exist or were not obtained and stored. To accentuate, it still comes into account the great ease of communication between devices that increases and the volume of transactions and also from openings to frauds.

This variety of devices favors a scenario of cyber attacks of many types by providing an attractive and profitable environment for cybercriminals.

So if you want to know about which threats you may be vulnerable to, how to protect them and even the relationship between information security and Industry 4.0, read this article through to the end.

What is cyber security?

Cybersecurity is the term used to denote procedures, practices and technologies that aim at digital security against illegal practices and damages to computers, networks, programs and data.

The dangers and harms that the Internet can cause have intensified cybersecurity debates around the world as more and more businesses, industries and governments use connected digital systems and this promotes a scenario of cybercrime attacks.

Now imagine the following situation: what would be the consequences if one of these networks were invaded?

• Partial or total loss of data;
• Theft of passwords, identity, bank data, among others;
• Bribe to rescue confidential information;
• Espionage;
• Manipulation of corporate data;
• Dissemination of SPAM;

The damage could be catastrophic and often irreversible. But do not panic, below I'll tell you a little bit more about what the types of attacks are and soon after some protective measures.

What are the types of attacks?

There are several types of attacks by cybercriminals, each of which operates in a different way by acting on various levels of security. As I explain, imagine that a protection system is an onion, that is, it contains several shells that need to be penetrated before reaching the nucleus.

Some of these attacks focus on passing through undetected levels, others on getting credentials from users, and there are also attacks that overwhelm the request server to congest communication.

Among the main types of attacks we can mention:

DDos

An abbreviation for Distributed Denial of Service,

this attack occurs when a server is purposely overloaded with hits and requests in order to make the page "fall". At that moment, users can not access, generating losses, for example, in the commercial sector because they can not make sales;

Malware

This term is the contraction in English of "Malicious Software" or in free translation (Malicious Software). It is a generalization of traditional and well-known viruses, spy programs, Scarewares, Trojan horses, screenshots and keyloggers (Keyloggers). They are programs used to gain unauthorized access, capture access credentials, or monitor the user.

Phishing

One of the most widely used forms of attack by its ease of expansion. Already received an email from promotions or bank but noticed that the sender was not truly the institution? Well, know this is Phishing.

It involves collecting personal information and information such as credit card through the resemblance of the legitimate website where the user can not perceive the small differences and provides his access credentials.

Internal attacks

They can be defined as actions of people who have physical access to administrative systems or privileges and use this advantage for their own benefit. Usually gets sensitive data or uses USB flash drives to install malware directly into the system.

As you may have noticed, many malicious people today have realized that failures in cybersecurity can be profitable. For this reason, it is necessary to take protective measures to avoid becoming vulnerable.

It is the function of cyber security to protect users, but it is also necessary to spread ideas of self-security. Below, I will explain some of the measures better.

What are the protective measures?

After a better understanding of some types of attacks, one wonders: How can I protect myself? According to cybersecurity experts, users themselves should take preventative measures. They are:

• Use original software and keep it up to date;
• Install a firewall, AntiSpam and antivirus;
• Be careful when connecting to Wi-Fi networks, especially those without a password;
• Encrypt your data;
• Make backups;
• Have secure and different passwords for each service;
• Be careful when sharing images, videos, and other information with applications.
• Use 2-step login whenever possible.

Now that you have understood better about doing your own cybersecurity, let's talk about future trends and about Industry 4.0.

Industry Cyber ​​Security 4.0

Naturally, anyone working with Information Technology (IT) is already used to dealing with day-to-day device security issues. Since the third industrial revolution, problems related to cybersecurity have been studied, but with the advent of the fourth industrial revolution or Industry 4.0, new challenges are emerging.

The difference is that, today, the industry has evolved and is investing in even more sophisticated means of control such as IoT (Internet of Things) devices, cloud computing, Big Data, Artificial Intelligence, autonomous robots, additive manufacturing, augmented reality and along with all these pillars, cybersecurity enters as a way to keep all data and processes safe.

Industry CyberPlans 4.0

SecurityUnlike individual protection measures, corporate and industrial cyber security plans involve much more system protection measures because they are environments where many people have access.

All these measures together are turning into the onion peels that I said earlier, making the direct entry into the nucleus more and more complex.

It is worth remembering that there is not only one way, the important thing is to be followed some basic premises, such as:

1. Internal Security Policy

Going straight to the point, it is very important to have an internal information security policy. This means that the company has taken legal action to protect data with which it works.

To get started, define simple clauses such as using internal documents, personal storage devices, and private email, and then go incrementally. Enter anything that is relevant to your business.

2. Access Control and Intrusion Detection

After learning the general about cyber security, it is clear why limit physical and logical access controls. Therefore, define digital IDs and access restrictions for employees across sectors and infrastructure areas. Keep face-to-face and intruder detection systems always up to date.

3. Use of digital signatures Digital

signatures are a secure and advanced type of encryption that follow cyber security standards. With them, it is possible to have a high level of reliability between each signer, which makes your company have authority and authenticity in the documents they sign.

4. Isolation of connection

Instead of connecting devices and machines directly to the Internet, make an internal network free of access (Intranet) and only then define protocols of communication with the external network (Internet).

Through the Intranet, it is possible to access corporate data located in a branch, in a secure way, by computers that are in the matrix, that is, it creates a channel of direct communication and still gains in the cybersecurity.

5. Monitoring systems and networks

Periodically scan your systems, run tests, monitor and trace end-to-end production. It is very common, when it comes to business cyber security, to think that it will never be invaded or that the system is fail-proof. For know that if you have not yet been invaded it is because you are now.

When we talk about projects, we think about something of great magnitude. This is a mistake, because a project may be involved with small day-to-day activities. We can cite some examples in solving internal problems, negotiating with suppliers, delivering products, implementing systems and strategies. The correct management of the projects brings benefits to the organization, being able to be used in problem-solving. Good project management defines precisely the decision-making processes and also identify causes and effects.
