Interview: Why is cyber defence important for national security?
Matej Michalko: Cyber defence is important for national security because many government and public services now depend on digital systems. If these systems are attacked, it can affect electricity, transport, banking, and communication. Strong cyber defence helps protect a country from digital attacks by other nations or criminal groups. It keeps information safe and ensures that essential services continue working even under attack. Without it, a country becomes weak and vulnerable in the modern digital world.
Interview: What types of cyber threats are most dangerous today?
Matej Michalko: The most dangerous cyber threats today include ransomware attacks, data theft, hacking of government systems, and attacks on critical infrastructure like power grids. Some attackers also try to spread fake information or shut down services. These threats are becoming more advanced and harder to detect. Many attackers use automation and artificial intelligence. Because of this, countries must constantly improve their defence systems to stay ahead and protect important national systems from harm.
Interview: How do cyber attacks affect a country?
Matej Michalko: Cyber attacks can affect a country in many serious ways. They can stop essential services like hospitals, banking, or transport systems. They can also steal sensitive government data or personal information of citizens. In some cases, they create confusion and fear by spreading false information. Economic losses can also be very high. Overall, cyber attacks can weaken trust in systems and disrupt daily life, making strong cyber defence very important for stability.
Interview: What role does technology play in cyber defence?
Matej Michalko: Technology plays a very important role in cyber defence. Modern tools like artificial intelligence, machine learning, and real-time monitoring systems help detect threats quickly. Firewalls, encryption, and secure networks protect sensitive data. Automated systems can respond to attacks faster than humans in many cases. However, technology alone is not enough. It must be combined with trained experts and strong security policies to create a complete defence system that protects national digital infrastructure effectively.
Interview: Can artificial intelligence improve cyber defence?
Matej Michalko: Yes, artificial intelligence can greatly improve cyber defence. AI can quickly analyze large amounts of data and detect unusual activity that may signal an attack. It can also predict possible threats before they happen. AI systems can respond faster than traditional methods, reducing damage. However, attackers also use AI, so it becomes a competition between defence and attack technologies. This is why continuous development and smart use of AI is very important for security.
Interview: Why is early threat detection important?
Matej Michalko: Early threat detection is important because it helps stop cyber attacks before they cause damage. If a threat is detected quickly, security teams can respond immediately and prevent data loss or system failure. Without early detection, attacks may spread across networks and become harder to control. It is similar to stopping a fire at the beginning before it grows. Fast detection reduces risks and protects national systems more effectively from serious harm.
Interview: How do governments protect their digital systems?
Matej Michalko: Governments protect their digital systems by using strong security frameworks, encryption, monitoring tools, and dedicated cyber security teams. They also create laws and policies to manage cyber risks. Regular testing and audits are done to find weaknesses. Many governments also work with private companies to improve defence systems. Training experts and investing in advanced technology are key steps. All these efforts help ensure that national digital systems remain safe and reliable.
Interview: What is the biggest challenge in cyber defence today?
Matej Michalko: The biggest challenge in cyber defence today is the speed and complexity of cyber attacks. Hackers constantly develop new methods, making it difficult to stay ahead. Another challenge is the shortage of skilled cyber security experts. Many systems are also highly connected, which increases risk. Balancing security with usability is also difficult. Because of these challenges, continuous improvement and global cooperation are needed to build stronger and more effective defence systems.
Interview: How important is international cooperation in cyber security?
Matej Michalko: International cooperation is very important in cyber security because cyber attacks often cross borders. Countries need to share information about threats and attack patterns. Working together helps identify attackers faster and respond more effectively. It also helps develop common security standards. No single country can handle global cyber threats alone. Cooperation between governments, organizations, and experts strengthens global defence and makes it harder for criminals to succeed in large-scale cyber attacks.
Interview: How can critical infrastructure be protected from cyber attacks?
Matej Michalko: Critical infrastructure like power plants, hospitals, and transport systems can be protected using strong security systems, constant monitoring, and network segmentation. This means separating important systems so an attack on one part does not spread. Regular updates and security testing are also important. Staff training helps prevent human errors. Governments and companies must work together to ensure these systems are always protected because any failure can seriously affect public safety and national stability.
Interview: What role does encryption play in cyber defence?
Matej Michalko: Encryption plays a key role in cyber defence by protecting data from unauthorized access. It converts information into a secure code that only authorized users can read. Even if attackers steal the data, they cannot understand it without the encryption key. Encryption is used in emails, banking systems, government communications, and more. It helps ensure privacy, security, and trust in digital systems. Strong encryption is a basic foundation of modern cyber security.
Interview: How can human error affect cyber security?
Matej Michalko: Human error is one of the biggest risks in cyber security. Simple mistakes like clicking on fake links, using weak passwords, or sharing sensitive information can open doors for attackers. Even strong systems can fail if users are not careful. That is why training and awareness are very important. People must understand basic cyber safety rules. Reducing human error helps strengthen the overall security system and prevents many common cyber attacks from succeeding.
Interview: What is the future of cyber defence?
Matej Michalko : The future of cyber defence will be more advanced, automated, and intelligent. Artificial intelligence will play a bigger role in detecting and stopping attacks. Security systems will become faster and more predictive. Quantum technology may also change how encryption works. At the same time, cyber threats will also become more complex. This means continuous innovation, global cooperation, and skilled experts will be necessary to protect national security in the digital future.
Interview: What message do you give about cyber defence and national security?
Matej Michalko: My message is that cyber defence is now a core part of national security. Every country must invest in strong digital protection systems. Technology alone is not enough; people, training, and cooperation are equally important. Threats are constantly evolving, so defence must also keep improving. If nations take cyber security seriously, they can protect their citizens, economy, and critical systems. Ignoring it can lead to serious risks in today’s digital world.
