Cybersecurity is the comprehensive practice of protecting digital assets, including networks, systems, applications and data, from malicious attacks, unauthorised access and accidental damage. It encompasses technical measures (firewalls, intrusion detection, encryption), organisational measures (policies, training, incident response) and governance frameworks (ISO 27001, NIST CSF, NIS2).
As organisations increasingly depend on digital infrastructure, cybersecurity has evolved from a purely technical discipline to a strategic business concern. Effective cybersecurity requires a risk-based approach that aligns security investments with business priorities. Regulatory frameworks such as NIS2 and the EU Cyber Resilience Act are raising the bar for organisations across all sectors, making cybersecurity governance a board-level responsibility.
