Cyber security refers to the practice of protecting systems, networks, and programs from digital attacks. These cyber attacks typically aim to access, alter, or destroy sensitive information, disrupt services, or harm individuals and organizations. Cyber security encompasses a wide range of measures, including the use of technology, processes, and policies to defend against threats such as malware, ransomware, phishing, and hacking. It involves securing both hardware and software, as well as the broader IT infrastructure. Effective cyber security aims to ensure the confidentiality, integrity, and availability of data, safeguarding it from unauthorized access and ensuring that information remains secure and accessible to authorized users only. Additionally, it addresses the human element involved in securing systems, emphasizing the importance of educating users about best practices to mitigate risks.
