What is Network Security?

Network security is a measure to protect systems, networks, and programs from being attacked or tampered with, including the security of network devices, network information, and network software. Its existence can prevent others from stealing important information which includes Network systems to Webpage Security, such as personal-related information, company secrets, and even state secrets, which may all become the scope of network security.

Since the mid-1980s, a computer virus was the earliest network security problem when Internet had become popular.

In the past decade, with the rise of social media and the Internet of Things, Network Security has become a very important issue. For companies, it is a subject that must pay attention to which can also be divided into "software" and "personnel".

Software

In order to use the Internet safely and protect the integrity of online information, we need to take many protections, such as improving the resource integration capacity of software and hardware, being able to identify the various threats right after facing it also take action to prevent proliferation or intrusion. The most important of all is Internet access rights which also need to be managed to avoid being targeted by others.

Personnel

Network Security is not just an issue that the IT department needs to pay attention to. All the employees in the company must be aware of the danger in both acknowledgment and behavior. They can identify users, judge the permission to use specific resources, and record the relationship between users and users. The data between systems is convenient for future management or analysis, so as to manage Network Security effectively.

The importance of Network Security

With the rapid progress of the Internet, information from individuals, and management to business operations have been transferred online. If attacked, it may cause various problems such as identity theft, extortion, or damage to important data there are also some problems related to life, health care and electricity, etc. It will cause major accidents and even affect people's lives if we don’t take any preventive actions. What advantages of Network Security?

Protect attacks by others directly on your Internet

Enterprises can enhance the confidence of customers and stakeholders

Higher assurance of business continuity and availability

Prevent unauthorized access to information

Comparison of Network Security, IT Security, and Information Security

The term Network Security is often used interchangeably with IT security or information security, and the difference between them is mainly in the scope of security range. IT security covers a wide range and concepts, including physical, information, and network security.

Conceptually, it protects the physical and digital aspects of an organization's internal infrastructure and information.

The scope of Network Security is mainly to protect against attacks on the network, such as flaw scanning, penetration testing, firewalls, and many important verification projects, all of which belong to the category of Network Security. Information security is more focused on protecting data. Last but not least, physical security is the measures to control the server room or office, including access cards, security guards, or cameras.

In fact, it is not only necessary to carry out complete planning for Network Security, but also to carry out multi-directional detection of data we had and protection methods, and also to cooperate with physical security protection in order to formulate a complete plan and protect the important data effectively.

Types of Network Security Threats

1.Phishing: This is one of the most common threat methods. It is believed that many people have received emails from fake trusted sources, stealing information through URLs or scams, such as login information, credit card numbers, bank accounts, etc.

2.Ransomware: There have been many news reports recently about ransomware. Hackers may block access to files or computer systems, and then ask for money from users, but even paying ransoms may not be restored.

3.Malware: Malicious code is designed to damage the device, possibly through advertisements.

4.Social engineering: Social engineering is for malicious people to use fraudulent methods to get users' information or charge users for fees or even obtain access rights to confidential information, and social engineering can also be combined with any of the above methods to achieve their goals.

What technologies may affect Network Security?

In addition to the above types of Network Security, there are many technologies nowadays that have potential risks to Network Security and are closely related to us. We must understand more in order to prevent them from happening.

Internet of Things

The popularity of the Internet of Things is obvious to all. The density of sensors, processors, and communication hardware information is very high in the Asia-Pacific region. Its security has also caused many concerns. For example, in the medical industry, if it appears on products, it will leak disease privacy or health-related information, and even affect the safety of patients, which will be a very serious problem.

5th generation mobile networks

5th generation mobile networks are more and more important in life. Whether it is a company or an individual, it will transmit information through the Internet, and the details of each user's life are closely related to it. If such private information is used by interested people, it will be many worrisome issues. Therefore, companies, governments, and suppliers need to pay more attention to this issue, otherwise, network security will become unknown.

Artificial Intelligence

Artificial intelligence is a popular technology in recent years, which can help us reduce the burden of management and provide decision-making assistance. However, if it is used by people with intentions to write more convincing phishing campaigns or Cyberattacks, it will become the enemy of enterprises or the public.

Conclusion

The rapid development of science and technology has brought more attention to the issue of Network Security. There are more and more problems with stealing information and defrauding behaviors happens. It is believed that all of you have seen many relevant reports. This no longer exists in individuals, but also extends to enterprises, countries, or even endangers life safety. Although we look forward to the development of future technology, Network Security is an issue that must exist and needs to be improved in order to prevent problems effectively.
