This paper deals with the safety evaluation of agrarian portals operated in the Czech Republic. It focuses mainly on security authentication process when accessing remote servers. The security of internet banking application has high level but the safety of agrarian portals seems to be very low. However, these systems contain sensitive data that must be adequately secured. The assessment covers “eAGRI” portal, “Portál farmáře” (Farmers portal), “Internet pro chovatele” (Internet for breeders) and “Agromanuál”. Two most popular domestic portals – „seznam.cz” and “Datové schránky” (Data boxes) were also included to compare the results of agricultural portals security. The aim of this paper is to point out the lack of security in relation to the management of user identities and suggest measures to improve safety.
