Invisible cyber attack! Introducing its visualization and countermeasures

recent years,"Cyber ​​attack"We often hear this word on the news. It is safe to say that cyber attacks are not just a matter of distant places; Japanese companies are also being targeted. However, even though it is called a cyber attack, many people may not have a clear idea of ​​what kind of attack is carried out. This time,How often do cyber attacks occur? Visualization and countermeasures for cyber attacksI would like to introduce about.

How often do cyber attacks occur?

Do you know how many cyberattacks Japan receives every year? In 2017,Approximately 105.4 billion itemscyber attacks have been detected. (From a survey by the National Institute of Information and Communications Technology)

In 2005, it was about 300 million, in 2010 it was about 5.6 billion, and in 2015 it was about 54.5 billion, so over the past 10 years or so,is rapidly increasing at an explosive rate.

Why are cyber attacks increasing so much? This is said to be because IoT has enabled all electrical products to be connected to the internet. There is a possibility that security cameras, which are supposed to be used as a security measure, may be infected with a virus.

invisible cyber attack

Approximately 105.4 billion cyber attacks have been detected in Japan alone, which means that by simple calculation, there are approximately 1000 cyber attacks per person, and most people are exposed to the threat of cyber attacks. It can be said that it is in a state of being.

But why do we have so few opportunities to experience this in our daily lives?

Because cyberattacks are carried out inside computers and networks, they are invisible to the naked eye.Is it difficult to grasp the actual situation?It is et al. Some people may not feel a real sense of cyber attacks because they are invisible.

Of course, if direct damage occurs, such as money being stolen or data being leaked, you will be aware of it. However, in many cases, it is difficult to obtain information about the attack method, purpose, clues, etc., and the probability of solving the case is very small. In order to take countermeasures against cyber attacks and prevent damage, first of all,It is important to visualize what kind of cyber attacks you are receiving.It will be.

Visualization of cyber attacks

Cyber ​​attacks areprofessional toolsIt can be visualized by introducing . Regardless of whether or not there is actual damage, you can learn the actual situation of cyberattacks, including those that can be prevented with existing security measures, and even those who are not familiar with IT can be aware of the approaching danger. You will be able to see that you are there.

Additionally, many cyberattacks originate from overseas, and in the world of the Internet, there are no physical borders, making you aware that you can be attacked at any time.

Many tools have already been released to visualize cyberattacks occurring around the world. For example, the National Institute of Information and Communications Technology provides the following tools:

This is a cyber attack visualization tool provided by a Japanese government agency. Here, we observe darknet traffic among cyber attacks.

Measures against cyber attacks

In the previous chapter, we discussed cyber attacks. So, what measures should we actually take?

To solve problems in the IT industryPDCA CycleThere is a way of thinking.

<PDCACycle>

1. Plan(plan)
2. Do(execution)
3. Check(evaluation)
4. Action (Improvement )

This approach can also be applied to the challenge of cyber attacks.

Visualization of cyber attacks①Planincluded in the early stages of By visualizing current threats and problems, you will be able to understand what countermeasures are required now.

The security measures you need vary greatly depending on your company's size, industry, and business. The situation and trends of attacks occurring around the world can be used to develop your own security measures, but for companies that have not yet implemented full-scale measures,First, understand the current state of attacks on your organization's systems.

The situation regarding cyber attacks changes daily. Measures once introduced may no longer be effective after a year. By using tools to visualize cyber attacks, etc.It is important to keep checking dailyis.

Visualize threats and develop countermeasures

As for what kind of tools to use, I think it would be best to use company policies and tools that are easy for each person to use.Above all, it is important to “visualize” threats.is. If you understand how many cyber-attack threats you are actually exposed to, you will understand the importance of countermeasures against cyber-attacks.

In addition, by understanding what kind of cyber attacks you are experiencing, you can determine what kind of security measures you should take.

In recent years, cyber attacks have become increasingly sophisticated, which has meant that those taking countermeasures have had to frequently review their own security measures.It may be useful to visualize cyber attacks in order to gather information on the latest cyber attacks..
