Definition of data classifications and class-specific security procedures

Critical
High
Normal
Low

Data classification can be used to give data processors a quick view of how critical data is and how data should be processed and protected.

The data categories used and the corresponding security levels are defined. The category of information is defined by analyzing the confidentiality, integrity and availability of the information in question, as well as any other requirements. Each level is given a clear and descriptive name.

Data classifications can be, for example, the following:

  • disclosure of information does not cause harm (PUBLIC)
  • disclosure of information causes slight inconvenience or minor operational annoyance (CONFIDENTIAL)
  • disclosure of information has significant short-term effects on operations or tactical objectives (LIMITED)
  • disclosure of information has serious implications for long-term strategic objectives or jeopardizes the very existence of the organization (PROHIBITED)

CONFIDENTIAL paper information may require e.g. the following protections:

  • Locked cabinet
  • Trusted transfer partner
  • Sealed envelopes
  • Safe disposal process

CONFIDENTIAL electronic information may require e.g. the following protections:

  • Use the selected encryption level
  • Password protection
  • Safe disposal process
  • More limited access rights

Encryption of public network traffic for application services

Critical
High
Normal
Low

Information included in application services transmitted over public networks must be protected against fraudulent and non-contractual activity and against unauthorized disclosure and alteration.

We use strong encryption and security protocols (eg TLS, IPSEC, SSH) to protect confidential information when it is transmitted over public networks in connection with the IT services we develop.
