ABSTRACT 
Internet security has been the subject of much debate over the past decade. Nowadays 
every industry and every business sector is aware of the importance of cybersecurity, 
however, the effects of the 4.0 revolution have raised issues of security and secure Internet 
connection. At the present time, the world is at the beginning of the fourth industrial 
revolution, one of its most prominent applications, the Internet of Things, which has shown a 
strong impact on all areas and the edge of life. The core of Internet of Things is the idea of 
using cyberspace as a means to improve performance, productivity, and customization of 
things. Through this, data is collected and transmitted from various things, such as production 
line equipment, sensors in the product at the customer base, sales data and more. This intense 
and continuous impact of Internet of Things has expanded the complexity of data security and 
information as things connect in the future. 
In an effort to shed light on the development of security on the Internet when the trend 
of typical application of the 4.0 Industrial Revolution is the Internet of Things developing 
robust, this article tries to identify risks in a connected business. The main purpose of this 
article is to show that the emergence of Internet of Things will reduce the gap between 
existing security and security. Based on that, the paper proposes some practical solutions to 
ensure Internet security for data transmission when things are connected.

1. INTRODUCTION 
Industrial revolutions are the events of an era in global history. The 18
th
-century 
steam-energy invention marks the beginning of the first revolution with machinery 
applications in the manufacturing process. The second industrial revolution witnessed the 
emergence of mass production by electric power and automation lines. With the third industry 
revolution marking the beginning of the electronic information age, the popularity of 
computers and the Internet has affected every aspect of life and business. While the fourth 
industry revolution is a broad framework for the future, the trend of Internet of Things makes 
the approach and application of the revolutionary 4.0 become more comprehensive, easier to 
understand and reveals the version. Substantial changes in technology affect the business 
activities of every business in the world. 
The enormous trends driven by Internet of Things are primarily related to the 
collection and transmission of data from the Internet to the Internet, thereby increasing the 
volume of data, enhancing the ability to analyze and process data. Diversified data, improved 
connectivity and communication between the digital and physical environment. Organizations 
that find meaning in these rich data sources will gain competitive advantage. But collecting 
detailed information means filtering out unnecessary information to obtain useful information 
and protecting the security and privacy of information, ensuring information security is not 
being accused of cards, blocking, theft or alteration by third parties. 
2. CONCEPTS AND PROCESS OF NETWORKING – PHYSICS OF 
INTERNET OF THINGS 
a. Concepts of Internet of Things 
According to the International Telecommunication Union (ITU) (2015), the Internet of 
Things (IoT) is a network of physical devices, vehicles and other embedded electronic 
gadgets with software, sensors and actuators. And networking allows these objects to collect 
and exchange data. Each item is uniquely identified through its embedded computer system

Iran's uranium enrichment facilities is a clear warning of the potential risk that may be due to 
the attacks. network. Power sector is not without the usual attacks like Ransomware locking 
system or Trojans stealing financial information. For example, in 2013, a US fuel distribution 
company was financially stealing $800 million. Every business in any industry or business 
TRƯỜNG ĐẠI HỌC HẢI PHÒNG 
649 
has its own risks, but an attack on the energy industry can be particularly serious and costly. 
Globally, the cost of a cyberattack in the energy sector is second only to attacks on financial 
services. 
+ Attack on the Ukrainian power grid: Another case is the attack on the Ukrainian 
grid, December 2015 and December 2016. The attack on the Ukrainian power grid caused a 
major disruption, affecting a large number of consumers in Western Ukraine. An organized 
attack was made for the purpose of creating maximum disruption. Malicious software was 
used to target the power supply network and use some penetration techniques such as online 
fraud, software documentation containing malicious software, and BlackEnergy. The security 
flaws have emerged from the availability of internal company information online and failed to 
implement two-step authentication frameworks on its VPN. Although the power returned 
within a few hours, the destructive programs destroyed a lot of valuable data. Exactly one 
year later, in December 2016, the Ukrainian grid was once again suspected of being attacked, 
leaving the entire city of Kiev in the dark. The attack was suspected due to external 
interference through the data network. 
+ Attacks Niche Pharmaceutical Company: One of the most well-known data theft 
cases was made at Niche Pharmaceutical Company in 2015. A large pharmaceutical company 
containing a database of over 50,000 customers were harmed by a hacker requesting a ransom 
and threatening to sell data on a common forum to the highest bidder. Online attack 
techniques like SQL injection have been used to perform this attack. The compromised data 
includes details such as customer's personal information and DEA number. The failure to 
apply appropriate encryption techniques was found to be one of the main reasons behind this 
attack. So it is not surprising that pharmaceuticals are in the top 3 industries vulnerable to 
online attacks. Electronic attacks on the pharmaceutical industry have grown faster than other 
industries. In Frost & Sullivan's study, more than two thirds of the pharmaceutical industry 
was severely affected, while the rest had at least one attack on the Internet. 
However, the wireless network threats in a pharmaceutical enterprise come from 
within the enterprise rather than from the external threats. More than twenty percent of IP 
burglars have internal corporate records and are not external hackers. Due to opportunism, 
revenge, greed or competitive advantage, people in the exploitation of their position to gain 
access to the company's digital assets. Organizations should actively do their part in securing 
digital assets. This can be achieved to a certain extent by educating staff about security and 
other protocols and ensuring a convenient way for staff to report suspicion. Manufacturers 
will need to ensure adequate protection of proprietary information and regularly monitor 
computer networks for suspicious activity. Companies must also ensure access to security 
measures, tools and frameworks for their employees, and ensure that access to corporate and 
network data is revoked against any employee. 
In many ways, the Stuxnet event, the Ukrainian Powerhouse, the Niche Pharmacy is a 
wake-up call for an upcoming industrial demand that requires industry recognition and 
planned investment. This gaining greater significance with the increasing complexity and 
intensity of cyber attacks is expected in the future. Figure 3 shows how cyber attacks have 
evolved over the years and what the industry is likely to see in the coming years.

Whether they are smartphone plants or refineries, businesses involve a myriad of 
equipment, systems, assets, and human resources. Traditionally, networking between devices 
and systems has been achieved through proprietary protocols. The proprietary nature of these 
protocols makes them isolated and inaccessible to any outside intrusion. The nature of 
protection against this cyber attack began to dwindle as businesses grew to new heights of 
Internet of Things and applications in business production via IP (Internet Protocol) 
connections connected to all devices, products in the business. For example, accepting IP-
based connections between devices in the enterprise with the core system has increased 
security risks, a fact that has been ignored until now. Other developments of the Internet of 
Things continue to expand the security risk is the increasing use of processors in the 
enterprise. This has made the enterprise's core control system the most vulnerable asset for 
attacks in the world of things that are naturally connected to the Internet. The uncontrolled 
nature of this expansion has made it possible for third-party intrusion via the Internet to be 
easily implemented across different layers of the enterprise. Some examples of devices within 
the enterprises that have security and security risks are PLCs, supervisory control and control 
(SCADA). data acquisition, distributed control systems (DCSs) and intelligent electronic 
devices (IEDs). With weak control connections, they can be a bridge for hackers to cause 
problems such as denial of access to systems (DDoS attacks), loss or manipulation of data on 
large scale, which results in negative impacts on the environment and defective systems. All 
of these breaches of confidentiality may result in loss of control over business operations, 
which can lead to loss of revenue and damage to the brand reputation of the business. 
4. BASIC SECURITY SOLUTIONS IN THE INTERNET OF THINGS 
TRƯỜNG ĐẠI HỌC HẢI PHÒNG

Many current security solutions in the IT world are not built to handle the complexity 
of an Internet of Things environment. Thus, information security and data networks have been 
identified as one of the top concerns in the field of business production - the sector has seen 
an increase in the number of attacks on the global network. 
Before applying the basic security solutions in the Internet of Things, for any network 
in a business or factory, it is imperative that businesses understand the security layers. 
Different approaches need to be applied to fully protect their production and business 
activities. Here, the method "Defense in Depth" or "Castle Approach" is the method given by 
the IIC. The "Defense in Depth" philosophy aims to secure many aspects of a business or 
organization, including: personnel, procedures, technology and the physical. Different 
security control layers include: Level of Government policy and security frameworks; 
Physical levels; Level of Network; System level; Application and data layers as shown in 
Figure 4 below. 
Figure 4: Enterprise security layers in IoT 
(Source: [2]) 
The application of in-depth protection involves a sequential and conditional approach. 
Different levels of security acceptance include the following: 
a. Security measures at the administrative level 
These include laws, regulations, policies, rules, and guidelines governing the 
organization's information security practices. Manufacturers who want to adopt online 
security need to have a better understanding of the network security laws and frameworks that 
protect specific area where the organization is located. 
Common misconceptions about network security include: 
+ It will not happen to me. 
+ Antivirus and firewall is enough. 
+ Not all endpoints need to be protected. 
+ Endpoint security can not provide. 
The Department of Homeland Security (DHS) emphasized on IoT security: When 
some devices are connected to malicious code with increasing rely on national critical 
infrastructure, ensuring that these systems are appropriate. It is a top priority. Manufacturers 
can apply these principles as they design, manufacture and use interconnected systems. These 
TRƯỜNG ĐẠI HỌC HẢI PHÒNG 
 652 
guidelines are important to help businesses make security decisions. The main high-level 
principles defined by DHS include: 
+ Combining security at the design stage: With the intention to maximize profits in a 
shorter time, manufacturers fail to secure their systems and processes. This leaves room for 
hackers to manipulate information in the network. The guidelines are set by DHS but instruct 
manufacturers to incorporate these principles into network security right from the design 
stage. 
+ Activation of security updates and vulnerability management: The old industrial 
machines are vulnerable to attack. These vulnerabilities can be solved by fixing 
vulnerabilities, providing security updates, and managing vulnerabilities. 
+ Using the best proven security practices: Proven and proven security best practices 
can be a starting point for implementing effective security measures in Internet of Things. 
+ Prioritized security by impact: The risks arising from network threats and 
corresponding access measures vary with the types of objects that are connected to the 
Internet. These security measures should be prioritized based on the magnitude and nature of 
potential impact. 
+ Enhancing transparency: Increasing transparency and visibility in plant processes 
can help determine where and how to implement security measures. 
+ Careful consideration of connectivity: Industrial enterprises should thoroughly 
analyze their business practices and understand whether there is a need for continuous 
connectivity when considering the risks associated with connectivity. 
b. Security solutions at the grassroots level (physical) 
Safeguards at the grassroots level can help companies build and maintain a positive 
reputation with their customers. Improving enterprise security also means improving 
productivity because it helps prevent unwanted theft or loss of data. This in turn can help 
expand business opportunities. At all times, businesses must ensure that the material aspects 
of the facilities include identifying and monitoring individuals in and out of the business. 
Businesses also need to track the movement of assets, equipment in the enterprise and supply 
chain, controlling access to sensitive areas in the enterprise. They also need to be constantly 
alerted by optimizing response times with potential threats and alerts. 
c. Security measures at the technical level 
 This includes the technological components of a network security system that 
helps protect connected assets. Many IT security providers provide end-to-end protection 
solutions, but not all provide comprehensive security for endpoints and the Internet of Things. 
For end users, any attack on the Internet of Things network can cause business losses and a 
loss of credibility. The growing complexity and intensity of wireless network attacks are 
driving demand not only to prevent a possible attack, but also to anticipate and prepare for 
future scenarios. It can happen if a real attack takes place. 
5. CONCLUSION 
Industrial Revolution 4.0 brings many new technology trends, such as the Internet of 
Things, requiring a more rigorous approach to information security issues and attacks from 
wireless connection environment through objects or devices. The connection between devices, 
assets, processes, and people has made the boundaries between the internal and external 
network lighter and more favorable for attackers to attack the system - the core of a business 
or an organization. Ensuring Internet security in an increasingly complex environment has 
become an inevitable strategic need for end users in all sectors and business areas. In order to 
establish solutions in a holistic way, the all-power approach has been presented in a secure 
order that ensures the security of the layers with different aspects that the enterprise needs to

establish in operating environment to minimize the disadvantages and maximize the 
advantages of the trend of Internet connection.
