    關於 安全 的常見問題

  • Information security, also known as information technology (IT) security, is the implementation and maintenance of systems to protect information or data. This includes responsibility for the security of data in all forms, including not only internet-connected computers but paper files, other types of physical media, and data stored offline.

    While cybersecurity is a subset of this field, it is focused primarily on the security of electronic data and computer technologies from threats via the internet. At the same time, many information security specialists also deal with common cybersecurity issues such as ransomware, spyware, viruses, and malware.
