The evolution of cybersecurity in the last 2 years.

Over the past two years, the cybersecurity landscape has evolved significantly. Increasing digitalisation and the risks that come with it have led companies and governments around the world to increase their efforts to ensure the security of their systems. This paper presents some of the most important developments in cybersecurity over the last two years.

Artificial Intelligence (AI) and Machine Learning (ML)

AI and ML have made great strides in recent years and are also of great importance in the cybersecurity landscape. These technologies make it possible to recognise complex patterns in large amounts of data and identify anomalies that indicate potential cyberattacks. Companies and governments are increasingly turning to AI and ML to protect their networks and systems.

Cloud security

The increasing use of cloud services has led to an increased focus on cloud security. Cloud providers have improved their security measures in recent years to minimise the risks of cyber attacks on their services. At the same time, companies have started to rely more on cloud security solutions to protect their data and systems in the cloud.

Quantum computing and post-quantum cryptography

The rapid development of quantum computing has the potential to break the existing cryptography algorithms used to secure data transmission and storage. Therefore, governments and companies have started to look at post-quantum cryptography, which is based on new mathematical concepts and is much more resilient on quantum computers.

Internet of Things (IoT) Security

The proliferation of IoT devices has increased dramatically in recent years, leading to new cybersecurity challenges. Many IoT devices are poorly protected and can be easily hacked. Companies and governments have therefore begun to look more closely at IoT security solutions to minimise the risks of cyberattacks on IoT devices.

Cybercrime and Ransomware

Cybercrime and ransomware attacks have increased in recent years and pose a significant threat to businesses and governments. Attackers are using increasingly sophisticated methods to gain access to systems and encrypt data in order to extort a ransom. Companies and governments are therefore increasingly focusing on prevention measures and contingency plans to respond to such attacks.

Overall, the cybersecurity landscape has made significant progress in the last two years. Companies and governments are increasingly turning to innovative technologies such as AI and ML to protect their networks and systems, and investing in cloud security solutions, post-quantum cryptography and IoT security to minimise the risks of cyberattacks. However, there continue to be new challenges that need to be addressed.

For example, the COVID-19 pandemic has led to an increase in cyberattacks as many businesses and governments have moved to remote working. Cybercriminals have used this opportunity to exploit vulnerabilities in systems and steal data. As a result, companies and governments have increased their focus on remote work security solutions and awareness training for their employees.

Another important trend is the collaboration between companies and governments on cybersecurity. Many governments have introduced laws and regulations to ensure the security of their critical infrastructure and to fight cybercrime. Increasingly, companies and governments are working together to share information and best practices to jointly combat cyber attacks.

In summary, the cybersecurity landscape has made significant progress over the past two years, but also continues to face new challenges. Businesses and governments must continue to focus on innovative technologies and collaboration to protect their systems and data from cybercrime threats.
