Cybersecurity is the practice of protecting systems, networks, and data from digital attacks, theft, and damage. It involves a range of technologies, processes, and practices designed to safeguard sensitive information, prevent unauthorized access, and ensure the confidentiality, integrity, and availability of data. Key areas include threat detection, data encryption, firewalls, and risk management, all aimed at defending against cyber threats such as hacking, malware, and phishing. As digital threats continue to evolve, cybersecurity is crucial for both individuals and organizations to maintain safety in an increasingly connected world.
