Cyber Security

Cyber security, or information security, is the practice of protecting computer systems, networks, and data from attacks, unauthorized access, damage, and theft. It includes a range of technologies, processes, and practices designed to protect computers, networks, programs, and data from cyberattacks. The fundamental aspects of cyber security include protecting sensitive information, preventing cyberattacks, monitoring networks for suspicious activity, and effectively responding to security incidents.


In everyday life, cyber security is essential for protecting personal and business information. For example, a bank uses advanced cyber security systems to protect its customers' financial data from cyber criminals. Companies implement security solutions such as firewalls, antivirus software, data encryption, and intrusion detection systems to protect their networks and sensitive data. Individuals also benefit from cyber security by using strong passwords, enabling two-factor authentication, and keeping software updated to protect their devices from malware and other threats. Sometimes, their internet router already has a firewall that ensures information security on the home network.


In Switzerland, cyber security is a national priority, given the importance of the financial sector and the increasing digitalization of society. The Swiss National Cyber Security Centre (NCSC) coordinates efforts to protect critical infrastructures and businesses from cyber threats. Swiss companies, especially network operators and internet providers, invest heavily in cyber security solutions to protect customer data and maintain market trust. Additionally, Switzerland collaborates internationally to address global cyber threats, participating in initiatives and partnerships to share information and improve resilience against cyberattacks.
