Explanation: Cybersecurity refers to the practice of protecting networks, systems, and data from cyber threats, including unauthorized access, cyberattacks, and data breaches. As technology advances, cybersecurity becomes increasingly essential for organizations and individuals alike.

A comprehensive cybersecurity strategy involves multiple layers of protection across networks, applications, and devices. Security measures include implementing firewalls, intrusion detection systems, and antivirus software, as well as conducting regular audits and awareness training.

The growing number of sophisticated cyber threats, such as ransomware and phishing attacks, has led to significant investments in cybersecurity solutions. Governments, businesses, and individuals need to collaborate to safeguard sensitive information and maintain digital security.

Formal Definition: Cybersecurity is the practice and technology of protecting computer systems, networks, and data from unauthorized access, disruption, theft, or damage by cyber threats.

Additional Information: Effective cybersecurity encompasses various domains, such as network security, application security, and operational security. It involves both preventive and reactive strategies to address cyber threats.

As cyber threats continue to evolve, cybersecurity frameworks like NIST and ISO/IEC 27001 provide organizations with guidelines for establishing secure environments. Cyber insurance is also becoming a common solution to mitigate financial losses resulting from security incidents.
