The developments in technology and cyber security in the last few years show that there may be surprise developments in 2021 as well. The increase in the number of people working from home and the acceleration of digital transformation can create various threats in terms of cyber security.

The year 2020, in which the coronavirus epidemic spread rapidly, led to significant changes in many areas of life. Cyber ​​security mistakes experienced in this process have brought negative results. That's why it's so important to stay informed about 2021 cybersecurity trends and anti-average methods. The cyber security trends of 2021 can be expressed as follows:

The type of media in which the image of a person in camera images can be partially or completely changed with the help of artificial neural networks can be defined as “Deepfake”. This technology allows people to be replaced by different people in photos or videos. This can pose serious risks to online conversations and meetings. Thanks to deepfake technology, malicious people can learn many important information about the company by using the photo and identity information of any company executive. In addition, fraud can be committed by impersonating employees. Therefore, Deepfake has a very important place among the cyber security trends of 2021.

The Internet of Things (IOT) is among the areas where hackers operate intensively. This cybersecurity trend can continue for many years. Today, IoT is a technology that is frequently used by consumers and companies in almost every field. The prevalence of working from home during the coronavirus process has made it debatable whether IOT is safe or not. If enough security measures are not taken in electronic devices, it may become easier for hackers to infiltrate these tools. In particular, employees using their individual devices and home internet while working at home can pose serious risks. Addressing this issue in 2021 can help prevent potential cyberattacks in the future.

Ransomware attacks are one of the most common types of cyber attacks. In fact, about 40 percent of attacks in 2020 are ransomware attacks. Therefore, similar attacks can be expected to continue in the coming years. Therefore, large companies should take more precautions against such attacks in the coming years.

Cryptocurrency, which has spread rapidly in recent years, is another technological tool that is targeted by hackers. Cryptocurrencies targeted by hackers may become more risky if they are not stored on reliable platforms. Therefore, increased fraud incidents in 2021 may continue to be among the cyber security trends in the coming years. Both investors and cryptocurrency platforms and virtual exchanges may need to take more security measures in this regard.

Most of the hacker phishing attacks in 2020, it was seen that attempts were made to seize the health records of individuals. Therefore, serious phishing attacks against the health sector took place in 2021 as well.

In 2021, it is seen that there are usually phishing attacks related to the COVID-19 outbreak and vaccine news. In this process, very serious phishing attacks were organized against vaccine research centres in the USA, England, and Canada. Therefore, it is very important that all institutions and organizations, especially governments, take precautions against possible types of cyber attacks that may occur in the coming years. In addition, individuals need to be much more careful to protect important information such as health records.

Finally, innovations in technology can bring with it many risks. Therefore, taking into account the cyber security threats in 2021, more accurate security steps should be taken in the new year.
