Information Security (Информационная безопасность)

Information security means protecting information and information systems from unauthorized access, use, disclosure, modification or destruction.
Since the early days of writing, heads of state and military commanders understood that it was necessary to provide some mechanism to protect the confidentiality of written correspondence and to have some means of detecting tampering.
For over twenty years, information security has held confidentiality, integrity and availability as the core principles of information security.
