Information Protection

SK-CERT strictly follows the rules in handling and processing of sensitive information. Therefore, in communication it uses Traffic Light Protocol (TLP) which ensures the information classification according to specified addressees. SK-CERT also uses PGP protocol for transfer of important information, whereas the public key for communication with SK-CERT can be found in Contact and Information.

TLP protocol

Traffic Light Protocol (TLP) was created in order to facilitate greater sharing of information. TLP is a set of designations used to ensure that sensitive information is shared with the appropriate audience. It employs four levels individually marked with different colour, whereas these levels separate individual distribution rules. SK-CERT uses TLP for sharing of information and also supports that protocol as a recipient and follows its rules. For reporting incidents and also in common communication with SK-CERT unit, please use TLP according to the following table:
