Cybersecurity is the practice of protecting computer systems, networks, and digital information from unauthorized access, attacks, and data breaches. It involves implementing measures such as firewalls, encryption, and intrusion detection systems to safeguard against cyber threats. Cybersecurity aims to ensure the confidentiality, integrity, and availability of information, defending against malicious activities like hacking, phishing, and malware. As technology advances, cybersecurity remains crucial in safeguarding individuals, organizations, and governments from the evolving landscape of cyber risks.
