Cybersecurity is the practice of protecting digital systems, networks, and data from cyber threats, including hacking, malware, and data breaches. As technology continues to evolve, so do the risks associated with cybercrime, making cybersecurity a critical field for individuals, businesses, and governments. Cybersecurity encompasses several key areas, such as network security, which protects systems from unauthorized access; cryptography, which ensures secure communication; and ethical hacking, which helps organizations identify vulnerabilities before malicious hackers can exploit them.
