Information Security Guide: Symbols and Abbreviations

Information security (IS) is responsible for protecting corporate networks, confidential and raw data, mobile applications, social networks, cloud computing, etc. It includes:

  • infrastructure security,
  • cloud security,
  • application security,
  • recovery in case of an incident,
  • incident response,
  • vulnerability management,
  • encryption (cryptography).

IS uses common abbreviations, abbreviations for security tools, as well as standards and certificates. So that an IT specialist or a novice IS specialist does not get confused, we have prepared this information security guide.
