Cybersecurity is the practice of protecting computers, servers, networks, and data from malicious attacks, unauthorized access, damage, or theft. It involves implementing measures such as firewalls, encryption, intrusion detection systems, and anti-virus software to safeguard digital assets. Cybersecurity also includes creating and enforcing policies, conducting regular risk assessments, and training employees to recognize and respond to potential threats. The goal is to ensure the confidentiality, integrity, and availability of information and systems, preventing cybercriminals from exploiting vulnerabilities.
