The digital transformation process brought an increase in the number of connected devices, including industrial devices, in what we call Industry 4.0. Ensuring cybersecurity is essential to keeping any business system up and running. With that in mind, we have brought here the main vulnerabilities of cybersecurity in industry 4.0, which corresponds to the period of technological breakthroughs we are experiencing.

It is no surprise that everyone is connected and so are businesses. However, just as regular users are at risk, business data is also in vulnerable, even dangerous, situations.

Industry 4.0 and cybersecurity

With the high volume of data circulating on several servers, malicious attackers and cybercriminals obviously arise. As such, they develop techniques for stealing data that often have financial value involved.

Considering that many companies operate through electronic and automated systems, the risk is high. Even with all the existing security, there are still no 100% secure systems against hackers.

With the increasing number of cyberattacks, it is crucial to guarantee protection against intrusions. In this scenario, cybersecurity arises in order to prevent and protect important data from these attacks.

Mainly marked by the large volume of data, Industry 4.0 simply lacks protection against virtual threats. Therefore, it is important to understand the main vulnerabilities that all technological developments have.

The dangers of interconnecting systems

Despite making the automation processes much easier for companies, services such as Cloud need to have increased security. If information was previously separated and organized in different locations, this technology has changed that.

With the interconnection of systems and with increasingly centralized storage, attackers have access to all information at once. If, on the one hand, the system becomes more and more intelligent, on the other hand, the risk becomes increasingly greater.

And that is why several companies invest in security. The hackers behind these attacks are constantly looking for loopholes in these systems. If a company does not keep up to date, it becomes a potential victim.

The biggest vulnerability in industry 4.0 is the inability to stop

The technological dependence of industry 4.0 is one of the most striking characteristics of the current period. Having information interrupted or leaked can mean immense monetary losses.

According to data from ITU (International Telecommunication Union), about R$ 80 billion have already been lost in cyberattacks in Brazil. And this figure refers to the period of 2017 and 2018 alone.

Therefore, In 2020 it could not be different. The jump was immense, and according to a report by McAfee, the impact on the economy for these crimes reaches US $ 1 trillion.

In this way, malicious criminals already have greater knowledge about the importance of data. Ransoms for data recovery are increasing and the attempts are becoming increasingly sophisticated.

The main vulnerabilities in cybersecurity and attacks today

With the ever-greater connection between data, it becomes much easier for an attacker to gain access to all of them. This is because of malicious software, which can access all centralized information.

The most common attacks, therefore, are:

• Through malware: here, apparently harmless software is installed on the computer with the user’s permission. With the virus inserted in the program, the attacker receives access to various data. Also, through this program, the criminal can limit the functions of the machine itself. The data can become inaccessible and be stolen by the attacker.
• Through ransomware: this type of attack is much more common in companies. This involves data hijacking, where the attacker can leave the data inaccessible and release it to the user through ransom payments.
• Phishing: it is a very recurring attack. In it, hackers can simulate a page identical to that of a bank, for example. Thus, the user is prompted to enter important data such as individual taxpayer ID, account, and others.
• ZeroDay: this type of attack is a little more common and occurs in newly launched applications. The criminal seeks, in several ways, to find flaws in applications before they are corrected.

Cloud storage and Artificial Intelligence are pillars of industry 4.0. What happens is that a lot of stolen information can easily allow access to much more valuable data.

The interconnection of systems, therefore, generates a lot of concern among cybersecurity experts. On the other hand, information will always be essential to prevent these attacks from being successful.

How to manage cybersecurity in industry 4.0

We can consider that many attacks occur by prior permission from users (as is the case with Trojan horses and Phishing). Although it is not the only factor that guarantees security, restricting users can minimize threats.

By limiting the number of people within the company that can access valuable data, the risk of losing them is much less. This is because, in cases of invasion of any of the machines, the main information will be, for the most part, protected.

It is very important that, for the maintenance of cybersecurity, a company pays attention to the following measures:

• Greater access controls;
• Data encryption; and
• Blocking of certain accesses (mainly from anonymous users);
• Keep the system updated, always exploring and correcting security flaws;
• Scanning for viruses and using an antivirus;
• Frequent updating of passwords and privileged users;
• Monitoring of security services.

The cybersecurity vulnerabilities are directly associated with the lack of maintenance in an organization’s security systems. Keeping systems up to date can be a chore, but it is always a must.

Considering the increasingly sophisticated and intelligent cyberattacks that we come across, we need to update ourselves too.

Otherwise, loopholes are exploited by hackers. The result? Even before a company learns about them, they have already been used for the invasion. A reliable security service is therefore essential in industry 4.0.

The Covid-19 pandemic has caused massive adoption of remote working models in organizations of all sizes. Besides, security leaders have also accelerated the migration of their infrastructure to cloud environments. According to a study conducted in partnership by Forrester and CloudFare, 52% of the organizations surveyed indicated that the pandemic has caused a shift to cloud-based working models.

In these models, both employees and third parties need to have access to critical systems through privileged credentials, so that they can perform their daily tasks. And with the increase in the number of third parties, there was also an increase in the number of data leaks attributed to them. According to a study by Trustwave, 63% of these security incidents were caused by third parties, which makes this type of access an important attack vector in organizations. The associated costs are also higher. According to the Cost of a Data Breach 2020 report, the average cost of a data leak reaches USD 3.86 million. And leaks caused by third parties were one of the factors associated with even greater losses.

Considering this infrastructure that is distributed outside the security perimeter, many people responsible for Information Security have made their cybersecurity policies less restrictive, allowing access through insecure devices and networks (including BYOD or Bring Your Own Device), even VPNs without the proper security controls in place. And we already know that it is impossible to track what is not managed.

All of these aspects introduced new business risks and concerns for cybersecurity teams. In a study published by PDM Insights, 73% of IT decision-makers who responded to the survey recognize these new challenges. The related risks include opening phishing emails (for 38% of respondents) and inappropriate administrative access (37%), which required CISOs to seek the implementation of Zero Trust-based approaches.

In Zero Trust models, there is no concept of trust within the perimeters of the organizations’ infrastructure, and all actions taken by users must be continuously verified. Forrester reports that the percentage of IT leaders who have accelerated their investments in Zero Trust-based technologies reaches 76%. In addition, the same percentage also identified Identity and Access Management (IAM) as the biggest challenge for their Security teams. An example of Zero Trust-based IAM technology is just-in-time access.

In just-in-time accesses, access to applications or systems is allowed only at predetermined periods and on-demand. Therefore, through just-in-time it is possible to grant the required privileges for the performance of certain administrative tasks through the provisioning and de-provisioning of access in time of use, thus reducing the attack surface and the associated cybersecurity risks. As organizations adapt to a new working model, which includes the consolidation of remote work and the increase of third parties in the infrastructure, the use of PAM tools is imperative for security leaders to ensure compliance with policies and security regulations, such as PCI-DSS, HIPAA, and SOx. Also, it is possible to meet the requirements of data protection laws, such as LGPD and GDPR, mitigating security risks and preventing data leaks that can cost millions in fines, in addition to the loss of revenue, customers, and corporate reputation.

To solve the problems involved in the remote work of employees and third parties, senhasegura has launched Domum, which offers users secure access based on Zero Trust to devices of the corporate infrastructure wherever they are, without the need for VPN, installation of agents, and additional licensing or configurations. Access is granted instantly, easily, and securely, without exposing device passwords and without the user needing access credentials to the PAM security platform.

It works as follows: whenever it is necessary for an employee or third party to perform remote access to any device managed by the PAM platform in the infrastructure, senhasegura Domum will perform the provisioning of access using a just-in-time approach, sending an approved access link to the user, allowing immediate access only to authorized devices.

senhasegura Domum allows configuring access workflows at multiple levels to allow access, in addition to the high granularity offered by the PAM security platform, already recognized by the market. In this way, it is possible to have maximum adherence to the organization’s access policies, allowing the reduction of implementation and customization costs. After the predetermined time of authorization, access is revoked and the link is no longer valid, preventing the employee or third party from proceeding with malicious privileged actions on devices in the infrastructure, which allows for a smaller attack surface and security risks associated with the exploitation of privileged credentials. Besides, by automating the process of granting and revoking privileged access on devices used by third parties, senhasegura ensures the reduction of operational expenses with access management.

Domum also offers all the features offered by the senhasegura PAM platform, such as real-time monitoring of the actions performed. Through LiveStream, an auditor can check the actions taken by a user, allowing the blocking or closing of the remote session in case of non-compliance or if a malicious action is detected. Other features of senhasegura also offered by Domum include session recording, analysis of threats user behavior. Thus, one can reduce the time to detect and respond to malicious actions before the malicious attacker is able to take them. As a result, there is maximum visibility of privileged actions performed in the environment and compliance with regulatory standards.

Ensuring the protection of remote access for a lot of users working remotely is more than an optional security requirement, it is a business must. Therefore, by using the senhasegura PAM platform and senhasegura Domum to manage privileged access, you can reduce the attack surface and the associated security risks, avoiding data leaks and ensuring business continuity.
